J Dent 2024; 146:105061. [PMID: 38729289 DOI: 10.1016/j.jdent.2024.105061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 05/08/2024] [Accepted: 05/08/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVES Orthognathic surgery (OS) has evolved with technological advancements, notably through the implementation of computer-assisted orthognathic surgery (CAOS). This article aims to elucidate various types of CAOS and their efficiency and accuracy, supplemented by a thorough literature review focusing on their clinical applications in South Korea. STUDY SELECTION, DATA, AND SOURCES A comprehensive search strategy was employed, including systematic reviews, meta-analyses, randomized controlled trials, and observational studies published until December 2023 in the PubMed, MEDLINE, and Google Scholar databases. The literature search was limited to articles written in English. RESULTS Static CAOS demonstrated high precision, reduced operative time, and high accuracy, suggesting its potential reliability in orthognathic procedures. Dynamic CAOS presented a promising avenue for exploration, showing an accuracy comparable to that of traditional methods. The critical considerations for CAOS include accuracy, time efficiency, and cost-effectiveness. Recent studies have indicated advancements in the time efficiency of static CAOS. Static CAOS requires less equipment and is more cost-effective than dynamic CAOS. CONCLUSIONS CAOS offers clear advantages over conventional OS in terms of surgical convenience and accuracy in implementing the surgical plan. To achieve recognition as the gold standard method for maxillofacial deformity treatment, CAOS must overcome its limitations and undergo continuous verification via well-designed studies. CLINICAL SIGNIFICANCE The introduction of CAOS, mainly static CAOS with high precision and reduced surgical time, signifies a notable advancement in OS. However, rigorous studies are warranted to validate CAOS as the gold standard for treating maxillofacial deformities.

Abstract
OBJECTIVES The aim of this study was to compare intaglio surface adaptation of the removable partial denture framework among various data acquisition techniques and fabrication approaches using three-dimensional comparison by metrology software. MATERIALS AND METHODS The partial edentulous typodont model with five digital superimposition landmarks was duplicated and scanned for the digital reference model. Three approaches were the conventional lost-wax (group I; LWT, n = 5), intraoral digital impressions combined with PolyJet printing and lost-wax (group II; IP-LWT, n = 5), and extraoral digital impressions combined with PolyJet printing and lost-wax (group III; EP-LWT, n = 5). Each framework was scanned and superimposed with the reference model. The misfits at 53 locations were measured. STATISTICAL ANALYSIS Data were statistically analyzed by one-way analysis of variance, followed by Tukey's honestly significant difference for pairwise comparisons (p < 0.05). RESULTS Significant differences were found between three approaches at the reciprocal arm, terminal part of the retentive arm, rest, and major connector (p < 0.05). In the LWT group, the reciprocal arm and palatal vault region of major connector had the lowest misfits, but the highest misfit was found in the midline region (p < 0.001). In the IP-LWT group revealed the most excessive contact at the terminal part of the retentive arm (-0.111 ± 0.038 mm, p = 0.031), with the highest misfit at the rest area (p < 0.001). CONCLUSION A difference in adaptation was found in several removable partial denture framework components among three approaches. The LWT group had a better adaptation than other groups. Nevertheless, a clinically acceptable adaptation was seen in all three approaches.

PeerJ 2023; 11:e16496. [PMID: 38077445 PMCID: PMC10710131 DOI: 10.7717/peerj.16496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 10/30/2023] [Indexed: 12/18/2023] Open
Abstract
Background The clinical teaching of esthetic implant-supported restoration of the atrophic maxilla is challenging due to the complexity and unpredictability of bone and soft tissue augmentation. The traditional problem-based learning and case-based learning method (PBL-CBL method) with a full digital workflow (digital PBL-CBL method) provides the students a chance to view clinical cases in a more accurate and measurable way. The aim is to evaluate the effectiveness of the new digital PBL-CBL method in teaching complex implant cases in esthetic area. Materials & Methods A full digital workflow of dental implant therapy was established for patients with severely atrophic anterior maxilla. The digital data of cases done in the new workflow was used as teaching materials in digital PBL-CBL teaching. Fifty-four postgraduate students were randomly selected and divided into three groups, including traditional PBL-CBL group (students taught in a PBL-CBL method with no digital cases), digital PBL-CBL group (students taught in a PBL-CBL method with full digital cases) and control group (students taught in didactic teacher-centered method). After training for three months, a study of the students' opinions on the corresponding teaching method was carried out through a feedback questionnaire. A theory test was used to evaluate students' mastery of knowledge about tissue augmentation and esthetic implant restoration. A case analysis was used to determine whether students could apply the knowledge to problem solving. Results The digital PBL-CBL method resulted in a higher rate of satisfaction than the traditional PBL-CBL method and the didactic teacher-centered method in all items except for "This approach decreases extracurricular work". Case analysis scores of the digital PBL-CBL group were significantly higher than that of the traditional PBL-CBL group and the control group. For the theory test, the digital PBL-CBL group (61.00 ± 6.80) but not traditional PBL-CBL group (55.22 ± 9.86) obtained a significant higher score than the control group (45.11 ± 12.76), although no significant difference was found between the digital PBL-CBL group and the traditional PBL-CBL group. Conclusion Compared with other methods, students taught with the digital PBL-CBL method showed higher satisfaction and better performance in acquisition of academic knowledge and ability in solving practical clinical problems. The digital PBL-CBL method provided a promising alternative for teaching complex implant cases at the anterior maxilla.

Abstract
PURPOSE The aim of this study was to evaluate the effect of light-emitting photobiomodulation therapy (LPT) on the rate of canine distalization. METHODS This study was performed on 60 extraction spaces formed by extraction of the upper first premolars of 30 patients (15 in the LPT group and 15 in the control group). Paul Gjessing (PG)-segmented canine retraction springs were used for canine distalization. In the LPT group, the Biolux OrthoPulse™ (Biolux Research Ltd, Vancouver, Canada) intraoral device (wavelength 850 nm LED light and an energy density of 63 mW/cm2 [±13 mW/cm2]) was used for 5 min per day over a period of 84 days. For each patient, the diagnosis was based on standard orthodontic documentation with photographs, digital model casts, and cephalometric and panoramic radiographs. The anchorage loss, canine rotations, canine inclinations, and molar inclinations were also evaluated on plaster models obtained on days 0, 21, 42, 63, and 84. The models were measured by using 3Shape OrthoAnalyzer software (3Shape, Copenhagen, Denmark). Measurements were made by a researcher and a blinded clinician. For statistical comparison, a paired-samples t‑test and one-way analysis of variance (ANOVA) were used at the p < 0.05 level. RESULTS The mean canine distalization rates were 1.36 mm/21 days and 1.02 mm/21 days in the LPT and control groups, respectively, and were statistically greater in the LPT group (p < 0.001). The amount of anchorage loss, canine rotations, canine inclinations and molar inclinations were not significantly different between the LPT and control groups at any of the timepoints. CONCLUSION LPT has the potential to accelerate orthodontic tooth movement by 33%.

[PMID: 37658317 PMCID: PMC10474673 DOI: 10.1186/s12903-023-03327-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 08/17/2023] [Indexed: 09/03/2023] Open
Abstract
BACKGROUND Dental technologies have increasingly been implemented in orthodontic practice to offer better experiences for orthodontists and patients, however, there is no scientific evidence yet whether which technologies should be implemented into the postgraduate programs. OBJECTIVES To investigate perceptions of orthodontic residents toward the confidence and importance of dental technologies, as well as to determine their necessity in postgraduate programs. MATERIALS AND METHODS The online questionnaire was designed to collect data from residents from all accredited orthodontic postgraduate programs in Thailand. The questionnaire consisted of four sections, which were (1) demographic data, (2) self-perceived importance of orthodontic technologies, (3) self-perceived confidence toward orthodontic technologies, and (4) the necessity of orthodontic technologies in postgraduate programs. The data were analyzed using descriptive statistics, Spearman correlation, and a chi-square test. RESULTS Intraoral scanner was found to be an orthodontic technology with the highest scores for both self-perceived importance (4.37 ± 0.59) and confidence (4.23 ± 0.75), followed by cone-beam computed tomography, digital treatment planning software, and lab-produced aligners. These orthodontic technologies were also considered as mandatory in orthodontic postgraduate programs. CAD/CAM technologies appeared to be least important, and their training may be arranged as short course training. There was no significant influence of training locations on the necessity of all orthodontic technologies (P > 0.05), except CBCT. Self-perceived importance and confidence in all technologies were found to have significant positive correlations (P < 0.05), except teledentistry and in-office aligners. CONCLUSION Orthodontic technologies were perceived as important in clinical workflow. Intraoral Scanners, CBCT, digital treatment planning software, lab-produced aligners, and digital modeling software appeared to be necessary for clinical practice and should be considered for orthodontic postgraduate programs, while other technologies may be arranged as short course training. Further research should investigate how to arrange and organize training sessions in orthodontic postgraduate programs.

Abstract
Background The aim of this study was to assess practicing dentists' characteristics and professional aspects that influence users to adopt Digital Technologies in Dentistry (DTD) in Saudi Arabia (SA). Moreover, we aimed to identify dentists' perceived barriers and challenges and to anticipate future potential developments towards implementing DTDs in their practices in SA. Methods This analytical cross-sectional study based on a validated questionnaire was conducted using a snowball sampling technique to include a conveniently selected sample of dentists from all dental specialties currently working in SA. Results The response rate was 64% completed and returned. A statistically significantly large share of Gen X (10.1%) used digital technologies (DTs) in dental practice compared with non-digital users. 40% received sufficient postgraduate education on DT, 92% agreed that DT should be included in the undergraduate dental curriculum. However, 79% actually gained skills or knowledge on DT through workshops and formal courses. 'Lack of practitioners' awareness', 'lack of education and pioneers' and 'lack of clinical evidence' were highlighted as the foremost barriers. Lower-frequency DT users believed that treating patients with DT makes treatment more predictable. Together, clinical trials and hands-on training courses can help overcome the barriers to the adoption of new dental technologies. Conclusions Exploring technology adoption and usage amongst practicing dentists allows healthcare stakeholders and policymakers to set a clear direction towards the digitalisation of the healthcare system and within healthcare organisations. The study also highlighted the foremost barriers, challenges and actions towards the adoption of DTDs.

Implementation of a Full Digital Workflow by 3D Printing Intraoral Splints Used in Dental Education: An Exploratory Observational Study with Respect to Students' Experiences. Dent J (Basel) 2022; 11:dj11010005. [PMID: 36661542 PMCID: PMC9858622 DOI: 10.3390/dj11010005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/11/2022] [Accepted: 12/16/2022] [Indexed: 12/28/2022] Open
Abstract
Fully digital workflows gained acceptance in dental practice and thereby are of interest for undergraduate education. An exploratory clinical observation was designed to track the implementation of such a workflow with novice digital users in order to describe its feasibility, time investment, and pitfalls. METHODS Students were invited to provide feedback for their experiences with a training module that consisted of the following: intraoral scanning, computer-aided design (CAD), manual finishing, and insertion of a 3D-printed bite splint for the lower jaw. RESULTS A total of 82 fourth-year students participated in the module. The average time required to perform an intraoral scan was 17 m 5 s, and all students were able to design a splint with an average time of 2 h 38 m. Students who indicated prior experience with CAD seem to outperform inexperienced students in both CAD task completion and intraoral scanning. The initial fit was reported as clinically acceptable by 68.5% of the participants, while 79% rated the workflow as very good to satisfactory and indicated that the training was helpful for dental practice. CONCLUSIONS The implementation of a digital workflow in undergraduate dental education is feasible and has acceptable clinical results. However, CAD is time-intensive, and the experience can be challenging.

Abstract
PURPOSE The purpose of this in vitro study was to assess whether scanning strategies of virtual interocclusal record (VIR) affect the accuracy of VIR during intraoral scanning. MATERIALS AND METHODS Five pairs of reference cubes were added to the digital upper and lower dentitions of a volunteer, which were printed into resin casts. Subsequently, the resin casts were articulated in the maximal intercuspal position in a mechanical articulator and scanned with an industrial computed tomography system, of which the VIR was served as a reference VIR. The investigated VIR of the upper and lower jaws of the resin master cast were recorded with an intraoral scanner according to 9 designed scanning strategies. Then, the deviation between the investigated VIRs and reference VIR were analyzed, which were measured by the deviation of the distances of six selected reference points on the upper reference cubes in each digital cast to the XY-plane between the investigated VIRs and reference VIR. RESULTS For the deviation in the right posterior dentitions, RP group (only scanning of right posterior dentitions) showed the smallest deviation. Besides, BP group (scanning of bilateral posterior dentitions) showed the smallest deviation in the left posterior dentitions. Moreover, LP group (scanning of left posterior dentitions) showed the smallest deviation in the anterior dentitions. For the deviation of full dental arches, BP group showed the smallest deviation. CONCLUSION Different scanning strategies of VIR can influence the accuracy of alignment of virtual dental casts. Appropriate scanning strategies of VIR should be selected for different regions of interest and edentulous situations.

[PMID: 34690040 DOI: 10.1016/j.ajodo.2020.08.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 08/01/2020] [Accepted: 08/01/2020] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Digital scanning, treatment planning, 3-dimensional imaging, and printing are changing the practice of orthodontics. These tools are adopted with the hope that treatment becomes more predictable, efficient, and effective while reducing adverse outcomes. Digital tools are impacting care, but knowledge of nationwide adoption trends and motivators is incomplete. METHODS We aimed to identify adoption decision-makers, information sources, incentives, and barriers through the first nationwide survey of American Association of Orthodontics members on their technology adoption habits, needs, and outcomes. Data were assessed using descriptive and bivariate analyses. The survey was developed from a comprehensive qualitative interview phase as part of a mixed methodology study. RESULTS Responses (n = 343) revealed orthodontists make adoption decisions on the basis of advice from other dentists and company representatives while rarely consulting staff or research literature. Continuing education and meetings are most effective at disseminating information to practicing doctors, whereas journals generate less impact. Key adoption incentives include added capabilities, practice efficiency, ease of implementation, and performance, whereas cost is the main barrier to purchase. Early adopters with larger practices charge higher fees than other adopters to support the costs of technologies. Treatment outcome is not a primary adoption incentive for specific technologies. CONCLUSIONS Orthodontists positively perceive the influence of intraoral scanning, cone-beam computed tomography imaging, 3-dimensional printing, computer-aided design-computer-aided manufacturing archwires, and clear aligner therapy on their practice and patient care. The orthodontic technological transformation is underway, and knowledge of adoption can guide our transition into modern practice, in which digital tools are effective adjuncts to the specialists' expertise.

Abstract
BACKGROUND To investigate the preference and perception on intraoral scanning and impression making among dental students. METHODS Final-year dental students from the 2019 and 2020 cohorts were invited to complete an online questionnaire via Google-Form. Their preference on the intraoral-scanning/impression making techniques and their perception on these techniques including the ease of defect identification, ease of infection control, need of chairside support, ease to master the technique as a beginner, efficiency in their hands and ease to handle the scanner software (yes/no) were collected. The results were analysed using McNemar tests and binary logistic regression test. All tests were performed at significance level α = 0.05. RESULTS Ninety-seven students participated in this study with a response rate of 96.0 %. Eighty-one students (83.5 %) have tried intraoral scanning on peers. Fifty-three (54.6 %) students preferred intraoral-scanning and were categorized as Pro-scanning group. Forty-four (45.4 %) students either preferred impression-making (n = 21) or not sure (n = 23) were categorized as Others. More than half of students in both groups felt that intraoral-scanning is easier to identify defect, easier in infection control and require less chairside support. Higher proportion of students in the Pro-scanning group felt that intraoral-scanning requires less chairside support, easier to master as a beginner, more efficient in their hands and they can deal well with the scanner software than that in Others (P < 0.05). Regression shown that students preferred a technique that they perceived is more efficient (P = 0.000). CONCLUSIONS While intraoral scanning has perceived advantages, many students still prefer impression making that works more efficient to them.

Abstract
PURPOSE To investigate the effect of impression technique (conventional preliminary alginate and digital scan) and operator experience in impression making (experienced in digital and conventional, experienced in conventional and inexperienced in digital, and inexperienced in conventional and digital) on impression time, satisfaction and stress levels, and the preference of the operators. MATERIAL AND METHODS One patient was assigned for each of the 60 operators, who were experienced in impression techniques at different levels (Group 1: experienced in conventional and digital, Group 2: experienced in conventional and inexperienced in digital, Group 3: inexperienced in conventional and digital). They made conventional impressions (irreversible hydrocolloid) and digital scans (Trios 3) from the same patient. The impression times were recorded at each step (patient registration, maxillary arch, mandibular arch, and bite registration) and in total. A visual analog scale (VAS) was used for the operator satisfaction for applicability, comfort, and hygiene; the State-Trait Anxiety Inventory form (STAI-TX1) was used for stress, and a questionnaire was completed to measure the operator's impression preference. The data were analyzed with a 2-way ANOVA and Chi-square test (α = 0.05). RESULTS A significant interaction was found between the operator experience in impression making and the impression technique on time for maxillary and mandibular arch impressions and total time (p ≤ 0.002). Operator experience and impression technique interaction had a significant effect on comfort and average VAS scores (p ≤ 0.016). Whereas, no significant effect of this interaction was found on stress (p ≥ 0.195). Operator experience in impression making had a significant effect on applicability (p < 0.001), and the impression technique had a significant effect on hygiene VAS scores (p < 0.001). Operators in Group 1 and Group 3 preferred the digital scans, however, operators in Group 2 had no preference (p = 0.022). CONCLUSION Operator experience in impression making and impression technique had varying effects on clinician's impression time, comfort, applicability, hygiene, and preference. Operators needed less time for the impressions they were experienced with. Operator stress level was not affected by the operator experience in impression making and the impression technique. Dental students and operators experienced in both techniques were satisfied with the digital scans and they preferred digital scans. Operators experienced with conventional impressions were satisfied with conventional impressions but didn't have a preference for the impression type.

Abstract
BACKGROUND Photographs and radiographs are indispensable resources for dental education, research and dissemination of clinical cases in scientific journals. The objective of this study was to evaluate the behaviour of dentists on the use of patients' images. MATERIAL AND METHODS Fifty-two dentists were interviewed using a semi-structured script containing open-ended questions on the use of patients' images. The answers were analysed using a qualitative-quantitative method of the discourse of the collective subject, and the distribution of the absolute and relative frequency of the answers was presented according to the central ideas obtained from the discourses. RESULTS The following central ideas on the use of patients' images were identified: (a) purpose: didactic and/or academic; (b) informed consent: verbal or absent when the patient cannot be identified; (c) discussion groups on social media contribute to learning; (d) most dentists would not appreciate and sue the author if they had their own photographs/imaging examinations posted on social media; 5. most dentists received some information on ethical regulations during dental school and state that images can be used with patient authorisation, without identification and for didactic/academic purposes. CONCLUSION Dentists consider the use of patients' images for didactic and scientific purposes beneficial, request informed consent to share mainly images that reveal the identity and would not appreciate if their personal images were shared without consent.

Abstract
Background This study aims to develop a novel process to establish a standardized manufacturing technique of customized esthetic ceramic bracket system (CCB) which could be endowed with individual color and shape to satisfy patients’ individual demands. Material characteristics and mechanical parameters of CCB were evaluated. Subjects and methods CCB virtual models were designed individually according to patient’s teeth morphology and clinical demands. 3D printing technology, lost-wax technology, and selected glass-ceramic ingots were employed to fabricate CCB. Scanning electron microscopy (SEM) analyses were performed to characterize the surface morphology of CCB and commercially available brackets (Clarity Advanced; Crystalline VII; Inspire ICE; Damon Q). Static and kinetic frictional resistance (FR), shear bond strength (SBS) and adhesive remnant index (ARI) scores were recorded. One-way analyses of variance (ANOVA) and post-hoc Tukey’s HSD multiple tests were used for statistical analyses. Results Multi-color and multi-transparency raw materials facilitated CCB with a wide range of color options and controllable optical properties to satisfy different esthetic demands of individual orthodontic patients. CCB presented same level of FR as commercially available ceramic brackets did. No significant differences (P ≥ 0.05) of SBS were observed among CCB-ES (treated silane), Clarity Advanced and Crystalline VII groups, and CCB-E (no silane) attained the highest ARI mean score 3. In the preliminary clinical trial, CCB presented excellent color-matching and shape-matching appearances similar to natural teeth, which made it highly invisible from social intercourse distance. Conclusions CCB were demonstrated to be an applicable labial orthodontic bracket system with optimized esthetics and biomechanics. We envision that it would be an ideal alternative for patients who pursue esthetic orthodontic treatment but were not likely to take lingual appliances or clear aligners.

Abstract
The increasing mainstream use of new technologies in the health professions (and in dentistry particularly) has given rise to an acute interest in what some identify as a new entity: that of digital or e-professionalism. We suggest there is no standalone notion of e-professionalism but rather professionalism in the digital age as an application of professional competence, values and behaviours within the realm of social media and digital technology.

Abstract
INTRODUCTION Orthodontics is evolving with advances in 3D imaging, additive fabrication, digital scanning, and treatment planning. With digital tools, orthodontic treatment may become more predictable, efficient, and effective while reducing side-effects. These technologies are affecting patient care, but knowledge of their adoption patterns and influence is incomplete. We aimed to identify adoption decision makers, information sources, perspectives, incentives, and barriers. METHODS Twenty-four privately practicing orthodontists were interviewed in a semistructured format following a topic guide. Interview transcripts were analyzed to identify factors in technology adoption and its perceived influence on practice. Thematic patterns were established through iterative systematic analysis, and qualitative validity was ensured with researcher triangulation. RESULTS Qualitative interviews revealed that orthodontists make purchasing decisions independently from staff, after consulting other dentists and company representatives. Meetings, residency training, and continuing education courses are influential information sources, whereas research literature is not. Early and middle adopters are integrating digital imaging, planning, and fabrication technologies into practice and view enhanced ease of use, capabilities, performance, and procedural efficiency as primary incentives to adoption. Improving outcomes and patient comfort are not frequently cited as incentives, and all interviewees view cost as the largest barrier. Orthodontists positively perceive the influence of technology on their practices, but are concerned that further innovation and direct-to-consumer products will cause loss of market share. CONCLUSIONS CAD/CAM appliances, 3D imaging, and digital treatment planning are viewed as future standards of care and are increasingly being incorporated into the orthodontic office. Understanding the technology adoption process can guide innovation to improve treatment and ease the transition into a digital workflow.

Abstract
INTRODUCTION Rapid developments in CAD/CAM technology necessitate the adaptation of curriculum content. Limited resources hinder institutions in holding state of the art equipment available for student training. MATERIALS AND METHODS A workshop given by an industry partner was organised as part of the final pre-clinical course in prosthodontics for the academic years 2015 and 2016. The workshop on dental ceramics and CAD/CAM technology comprised of lectures and practical demonstrations. Multiple-choice examinations prior to and after the workshop as well as questionnaires were used for assessing effectiveness and students' perception. The test scores and evaluation results were compared using Fisher's exact test of homogeneity (α = 0.05). RESULTS The workshop improved students' performance in the written examination. With the exception of 1 question, students having attended the workshop performed significantly better (P < .05). The majority of students felt that the workshop fostered their knowledge in the field of dental ceramics and CAD/CAM. Whilst only a small portion (<10%) disapproved industry-supported education, up to 45% of the participants considered the workshop as sales promotion. The students were undecided on whether or not competitor companies should be invited to present on the same topic and whether or not more industry-supported courses would be beneficial. DISCUSSION Industry-supported education appears to be a necessity in the field of CAD/CAM dentistry, but care has to be taken to select adequate partners, and the content of courses has to be controlled.

Abstract
Digital protocols are increasingly influencing prosthodontic treatment concepts. Implant-supported single-unit and short-span reconstructions will benefit mostly from the present digital trends. In these protocols, monolithic implant crowns connected to prefabricated titanium abutments, which are created based on data obtained from an intraoral scan followed by virtual design and production, without the need of a physical master cast, have to be considered in lieu of conventional manufacturing techniques for posterior implant restorations. No space for storage is needed in the complete digital workflow, and if a remake is required a replica of the original reconstruction can be produced quickly and inexpensively using rapid prototyping. The technological process is split into subtractive methods, such as milling or laser ablation, and additive processing, such as three-dimensional printing and selective laser melting. The dimensions of the supra-implant soft-tissue architecture can be calculated in advance of implant placement, according to the morphologic copy, and consequently are individualized for each patient. All these technologies have to be considered before implementing new digital dental workflows in daily routine. The correct indication and application are prerequisite and crucial for the success of the overall therapy, and, finally, for a satisfied patient. This includes a teamwork approach and equally affects the clinician, the dental assistant and the technician as well. The digitization process has the potential to change the entire dental profession. The major benefits will be reduced production costs, improvement in time efficiency and fulfilment of patients' perceptions of a modernized treatment concept.

Abstract
Despite accounting for a very small percentage of the population that adopts an innovation, the ‘innovators’ and ‘early adopters’ — representing the two earliest groups of individuals to acquire the new product or service — play a crucial role in the dissemination of the innovation to larger market segments. The objective of this paper is to understand the characteristics of these individuals that positively influence their decisions to adopt innovations. We argue that awareness of these traits will enable firms to attain speedier uptake of their offerings while aiding policymakers achieve quicker and wider proliferation of new technologies intended for societal benefit. We undertake a review of the literature studying the diffusion of innovations and show future directions that this framework should take to analyse the adoption lifecycle.

Abstract
Objectives To overcome challenges in the implementation of electronic dental record systems in a low-resource setting, it is crucial to know the level of users’ satisfaction with the existing system of paper-based dental records and their perceptions of electronic dental records. Methods A cross-sectional paper-based questionnaire survey was conducted among Myanmar dental professionals who worked in one of two teaching hospitals or in private dental clinics. Descriptive data were analyzed and regression analysis was carried out to identify factors influencing perceptions of electronic dental records. Results Most dental professionals (>60%) were satisfied with just three out of six aspects of paper-based dental records (familiarity, flexibility, and portability). In addition, generalized positive perceptions were found among decision makers towards electronic dental records, and 86% of dentists indicated that they were willing to use them. Financial concerns were identified as the most important barrier to the implementation of electronic dental records among dentists who were not willing to use the proposed system. Conclusions The first step towards implementing electronic dental records in Myanmar should be improvement of the content and structure of paper-based dental records, especially in private dental clinics. Utilization of appropriate open-source electronic dental record software in private dental clinics is recommended to address perceived issues around financial barriers. For the long term, we recommend providing further education and training in health informatics to healthcare professionals to facilitate the efficient use of electronic dental record software in Myanmar in the future.

Abstract
The aim of this randomized controlled trial was to analyze inexperienced dental students' perceptions of the difficulty and applicability of digital and conventional implant impressions and their preferences including performance. Fifty undergraduate dental students at a dental school in Switzerland were randomly divided into two groups (2×25). Group A first took digital impressions in a standardized phantom model and then conventional impressions, while the procedures were reversed for Group B. Participants were asked to complete a VAS questionnaire (0-100) on the level of difficulty and applicability (user/patient-friendliness) of both techniques. They were asked which technique they preferred and perceived to be more efficient. A quotient of "effective scan time per software-recorded time" (TRIOS) was calculated as an objective quality indicator for intraoral optical scanning (IOS). The majority of students perceived IOS as easier than the conventional technique. Most (72%) preferred the digital approach using IOS to take the implant impression to the conventional method (12%) or had no preference (12%). Although total work was similar for males and females, the TRIOS quotient indicated that male students tended to use their time more efficiently. In this study, dental students with no clinical experience were very capable of acquiring digital tools, indicating that digital impression techniques can be included early in the dental curriculum to help them catch up with ongoing development in computer-assisted technologies used in oral rehabilitation.

van der Zande MM, Gorter RC, Bruers JJM, Aartman IHA, Wismeijer D. Dentists' opinions on using digital technologies in dental practice. Community Dent Oral Epidemiol 2017; 46:143-153. [PMID: 28983942 DOI: 10.1111/cdoe.12345] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Revised: 07/24/2017] [Accepted: 09/05/2017] [Indexed: 11/29/2022]
Abstract
OBJECTIVES To investigate which opinions among dentists are associated with level of technology use, when characteristics of the dentist and dental practice, as well as motivating work aspects are taken into account. METHODS A total of 1000 general dental practitioners in the Netherlands received a questionnaire on digital technologies they use, opinions on using technologies and related motivating work aspects. Questions were derived from expert interviews, the Dentists' Experienced Job Resources Scale and literature on technology implementation. Technology use was measured as the number of technologies used, and divided into three technology user groups: low (using 0-4 technologies, mostly administrative and radiographic technologies), intermediate (using 5-7, more varied technologies) and high technology users (using 8-12, including more innovative diagnostic technologies). Opinions on technology use and motivating work aspects were analysed using principal components analysis (PCA) and exploratory factor analysis. Scores on all components and factors were calculated for each respondent by computing the mean of all valid responses on the underlying items. Differences in these scale scores on opinions among the technology user groups were assessed using one-way analysis of variance and Kruskal-Wallis tests. A multiple linear regression analysis assessed the association of scale scores about opinions on technology use with the sum of technologies used, taking into account motivating work aspects and characteristics of the dentist and dental practice. RESULTS The response rate was 31%. Dentists who were high technology users perceived technologies as yielding more improvements in quality of care, adding more value to the dental practice and being easier to use, than low technology users. High technology users thought technologies added more value to their work and they reported higher skills and resources. They also focused more on technologies and thought these are more ready to use than low technology users. High technology users derived more motivation from "Immediate results" and "Craftsmanship" than low technology users. Personal and practice characteristics, motivating work aspects, and the opinion scales "Focus" and "Added value to dentist" explained 50% of the variance in the number of technologies a dentist uses. CONCLUSION Opinions on digital technologies among dentists and motivating work aspects vary with level of technology use. Being more focused on technologies and perceiving a higher added value from using them are associated with using more digital dental technologies, when taking into account motivating work aspects and characteristics of the dentist and dental practice.

Joda T, Zarone F, Ferrari M. The complete digital workflow in fixed prosthodontics: a systematic review. BMC Oral Health 2017; 17:124. [PMID: 28927393 PMCID: PMC5606018 DOI: 10.1186/s12903-017-0415-0] [Citation(s) in RCA: 200] [Impact Index Per Article: 28.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Accepted: 09/13/2017] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND The continuous development in dental processing ensures new opportunities in the field of fixed prosthodontics in a complete virtual environment without any physical model situations. The aim was to compare fully digitalized workflows to conventional and/or mixed analog-digital workflows for the treatment with tooth-borne or implant-supported fixed reconstructions. METHODS A PICO strategy was executed using an electronic (MEDLINE, EMBASE, Google Scholar) plus manual search up to 2016-09-16 focusing on RCTs investigating complete digital workflows in fixed prosthodontics with regard to economics or esthetics or patient-centered outcomes with or without follow-up or survival/success rate analysis as well as complication assessment of at least 1 year under function. The search strategy was assembled from MeSH-Terms and unspecific free-text words: {(("Dental Prosthesis" [MeSH]) OR ("Crowns" [MeSH]) OR ("Dental Prosthesis, Implant-Supported" [MeSH])) OR ((crown) OR (fixed dental prosthesis) OR (fixed reconstruction) OR (dental bridge) OR (implant crown) OR (implant prosthesis) OR (implant restoration) OR (implant reconstruction))} AND {("Computer-Aided Design" [MeSH]) OR ((digital workflow) OR (digital technology) OR (computerized dentistry) OR (intraoral scan) OR (digital impression) OR (scanbody) OR (virtual design) OR (digital design) OR (cad/cam) OR (rapid prototyping) OR (monolithic) OR (full-contour))} AND {("Dental Technology" [MeSH) OR ((conventional workflow) OR (lost-wax-technique) OR (porcelain-fused-to-metal) OR (PFM) OR (implant impression) OR (hand-layering) OR (veneering) OR (framework))} AND {(("Study, Feasibility" [MeSH]) OR ("Survival" [MeSH]) OR ("Success" [MeSH]) OR ("Economics" [MeSH]) OR ("Costs, Cost Analysis" [MeSH]) OR ("Esthetics, Dental" [MeSH]) OR ("Patient Satisfaction" [MeSH])) OR ((feasibility) OR (efficiency) OR (patient-centered outcome))}. Assessment of risk of bias in selected studies was done at a 'trial level' including random sequence generation, allocation concealment, blinding, completeness of outcome data, selective reporting, and other bias using the Cochrane Collaboration tool. A judgment of risk of bias was assigned if one or more key domains had a high or unclear risk of bias. An official registration of the systematic review was not performed. RESULTS The systematic search identified 67 titles, 32 abstracts thereof were screened, and subsequently, three full-texts included for data extraction. Analysed RCTs were heterogeneous without follow-up. One study demonstrated that fully digitally produced dental crowns revealed the feasibility of the process itself; however, the marginal precision was lower for lithium disilicate (LS2) restorations (113.8 μm) compared to conventional metal-ceramic (92.4 μm) and zirconium dioxide (ZrO2) crowns (68.5 μm) (p < 0.05). Another study showed that leucite-reinforced glass ceramic crowns were esthetically favoured by the patients (8/2 crowns) and clinicians (7/3 crowns) (p < 0.05). The third study investigated implant crowns. The complete digital workflow was more than twofold faster (75.3 min) in comparison to the mixed analog-digital workflow (156.6 min) (p < 0.05). No RCTs could be found investigating multi-unit fixed dental prostheses (FDP). CONCLUSIONS The number of RCTs testing complete digital workflows in fixed prosthodontics is low. Scientifically proven recommendations for clinical routine cannot be given at this time. Research with high-quality trials seems to be slower than the industrial progress of available digital applications. Future research with well-designed RCTs including follow-up observation is compellingly necessary in the field of complete digital processing.

Time efficiency, difficulty, and operator's preference comparing digital and conventional implant impressions: a randomized controlled trial. Clin Oral Implants Res 2016; 28:1318-1323. [PMID: 27596805 DOI: 10.1111/clr.12982] [Citation(s) in RCA: 86] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/17/2016] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The aim of this randomized controlled trial was to analyze implant impression techniques applying intraoral scanning (IOS) and the conventional method according to time efficiency, difficulty, and operator's preference. MATERIAL AND METHODS One hundred participants (n = 100) with diverse levels of dental experience were included and randomly assigned to Group A performing digital scanning (TRIOS Pod) first or Group B conducting conventional impression (open tray with elastomer) first, while the second method was performed consecutively. A customized maxillary model with a bone-level-type implant in the right canine position (FDI-position 13) was mounted on a phantom training unit realizing a standardized situation for all participants. Outcome parameter was time efficiency, and potential influence of clinical experience, operator's perception of level of difficulty, applicability of each method, and subjective preferences were analyzed with Wilcoxon -Mann-Whitney and Kruskal-Wallis tests. RESULTS Mean total work time varied between 5.01 ± 1.56 min (students) and 4.53 ± 1.34 min (dentists) for IOS, and between 12.03 ± 2.00 min (students) and 10.09 ± 1.15 min (dentists) for conventional impressions with significant differences between the two methods. Neither assignment to Group A or B, nor gender nor number of impression-taking procedures did influence working time. Difficulty and applicability of IOS was perceived more favorable compared to conventional impressions, and effectiveness of IOS was rated better by the majority of students (88%) and dentists (64%). While 76% of the students preferred IOS, 48% of the dentists were favoring conventional impressions, and 26% each IOS and either technique. CONCLUSIONS For single-implant sites, the quadrant-like intraoral scanning (IOS) was more time efficient than the conventional full-arch impression technique in a phantom head simulating standardized optimal conditions. A high level of acceptance for IOS was observed among students and dentists.

Abstract
The objective of this study was to explore factors affecting decisions to adopt new technologies into dental practice using a colorimetric rinse test for detection of periodontal disease as a model. Focus groups with key informants in Canadian dentistry and dental hygiene were conducted. A deductive approach used Rogers's diffusion of innovation theory as a framework for organizing codes and subcodes. Two members of the research team independently reviewed and analyzed the data using NVivo 10. The attributes of the technology itself emerged as primary influencers. Perceived relative advantages of the diagnostic mouth rinse over existing methods were potential time efficiency, low implementation cost, and utility of the tool. Low complexity, compatibility with existing routines/beliefs, and the potential for reinvention-the use of a technology for other than its intended purpose (i.e., patient education, monitoring of disease, screening tool in nondental settings)-were other important features enhancing adoption. An overarching concern was that any new technology benefit the patient. Contextual factors also play a role. Numerous communication channels, including opinion leaders, patients, marketing, continuing education courses, and strength of evidence, influenced clinicians, with peer interaction being a stronger influence than marketing. Similar themes arose from specialist, general dentist, and dental hygienist focus groups. Adopter characteristics also came into play: participants ranged in their self-reported innovativeness with many considering themselves "early adopters" of new technology. Findings of this study suggest that the innovation adoption process is not straightforward, but attributes of the innovation, contextual factors, and adopter characteristics play important roles in the process. Knowledge Transfer Statement: Various factors affect the adoption of new tools into clinical dental practice. These include attributes of the test or tool itself, the context of the settings in which the tool is introduced to practitioners, and the characteristics of the clinicians themselves. A qualitative study of dentists and dental hygienists investigated these factors. Situations in which dentists and hygienists interact with their peers and colleagues-through social networks, continuing education courses, conventions, or personal contact-were a major driver in the decision to adopt new technologies. However, even among "early adopters," most were reluctant to use new tests or tools unless they perceived a benefit to their patients or practice.

Abstract
OBJECTIVES The aim of the randomized controlled trial was to analyze time-efficiency of a treatment with implant crowns made of monolithic lithium disilicate (LS2) plus titanium base vs. porcelain fuse to zirconium dioxide (ZrO2 ) in a digital workflow. MATERIALS AND METHODS Twenty study participants were included for single-tooth replacement in premolar and molar sites. Baseline was the start of the prosthetic treatment. All patients received transocclusal screw-retained implant reconstructions on a soft tissue level-type implant. The 3D implant position was captured with intraoral optical scanning (IOS). After randomization, ten patients were restored with CAD-/CAM-produced monolithic LS2-crowns bonded to prefabricated titanium abutments without any physical models (test), and ten patients with CAD-/CAM-fabricated ZrO2 -suprastructures and hand-layered ceramic veneering with milled master models (control). Every single clinical and laboratory work step was timed in minutes and then analyzed for time-efficiency with Wilcoxon Rank Sum Tests. Direct costs were assessed for laboratory fees for first line production in Swiss Francs (CHF). RESULTS Two clinical appointments were necessary for IOS and seating of all implant crowns. The mean total production time, as the sum of clinical plus laboratory work steps, was significantly different, resulting in 75.3 min (SD ± 2.1) for test and 156.6 min (SD ± 4.6) for control [P = 0.0001]. Analysis for clinical treatment sessions showed a significantly shorter mean chair time for the complete digital workflow of 20.8 min (SD ± 0.3) compared to 24.1 min (SD ± 1.1) [P = 0.001]. Even more obvious were the results for the mean laboratory work time with a significant reduction of 54.5 min (SD ± 4.9) vs. 132.5 min (SD ± 8.7), respectively [P = 0.0001]. CONCLUSION The test workflow was more time-efficient than the controls for implant-supported crowns; notably, laboratory fabrication steps could be effectively shortened with the digital process of monolithic LS2 plus titanium base resulting in more than 30% reduced overall treatment costs.

Abstract
PURPOSE The aim of this prospective cohort study was to investigate clinical and laboratory performance of implant-supported reconstructions comparing the digital to the conventional workflow. MATERIALS AND METHODS Twenty study participants were treated in a cross-over design for single-tooth replacement in posterior sites, each with a customized titanium abutment plus computer-assisted design and computer-assisted manufacturing (CAD/CAM)-zirconia-suprastructure (test: digital workflow; n = 20) and a standardized titanium abutment plus PFM-crown (control: conventional pathway; n = 20). Evaluation of the 40 reconstructions included: 1) feasibility of laboratory cross-mounting of each abutment-crown-connection, and 2) assessment of adaptation time for clinical adjustments of interproximal and occlusal surfaces. Statistical analyses were performed using the exact Wilcoxon rank sum tests. RESULTS Laboratory cross-mounting was feasible for three reconstruction pairings revealing a 15% vice versa transfer success rate. All implant crowns could be provided successfully within two clinical appointments, independently of the workflow used. The mean clinical adjustment time was significantly lower (p < .001) for test reconstructions from the digital workflow with 2.2 min (standard deviation [SD] ± 2.1) compared with the ones from the conventional pathway with 6.0 min (SD ± 3.9). CONCLUSIONS The digital workflow was almost threefold more efficient than the established conventional pathway for fixed implant-supported crowns. Clinical fitting could be predictably achieved with no or minor adjustments within the digital process of intraoral scanning plus CAD/CAM technology.

Abstract
Objectives To investigate (1) the degree of digital technology adoption among general dental practitioners, and to assess (2) which personal and practice factors are associated with technology use. Methods A questionnaire was distributed among a stratified sample of 1000 general dental practitioners in the Netherlands, to measure the use of fifteen administrative, communicative, clinical and diagnostic technologies, as well as personal factors and dental practice characteristics. Results The response rate was 31.3%; 65.1% replied to the questionnaire on paper and 34.9% online. Each specific digital technology was used by between 93.2% and 6.8% of the dentists. Administrative technologies were generally used by more dentists than clinical technologies. Dentists had adopted an average number of 6.3±2.3 technologies. 22.5% were low technology users (0 to 4 technologies), 46.2% were intermediate technology users (5 to 7 technologies) and 31.3% were high technology users (8 to12 technologies). High technology users more frequently had a specialization (p<0.001), were younger on average (p=0.024), and worked more hours per week (p=0.003) than low technology users, and invested more hours per year in professional activities (p=0.026) than intermediate technology users. High technology use was also more common for dentists working in practices with a higher average number of patients per year (p<0.001), with more dentists working in the practice (p<0.001) and with more staff (p<0.001). Conclusion With few exceptions, all dentists use some or a substantial number of digital technologies. Technology use is associated with various patterns of person-specific factors, and is higher when working in larger dental practices. The findings provide insight into the current state of digital technology adoption in dental practices. Further exploration why some dentists are more reluctant to adopt technologies than others is valuable for the dental profession’s agility in adjusting to technological developments.
