A new, short, specific questionnaire (QoLIP-10) for evaluating the oral health-related quality of life of implant-retained overdenture and hybrid prosthesis wearers

Impact of prosthetic rehabilitation on oral health-related quality of life of Saudi Adults: A prospective observational study with pre-post design

This study aimed to assess the impact of prosthetic treatment on the quality of life of partially/completely edentulous patients through the Oral Health Impact Profile-14 (OHIP-14) scale. This pre-post observational study was conducted in the College of Dentistry, Imam Abdulrahman Bin Faisal University, Saudi Arabia, between November 2022 and September 2023. Eligible participants were those aged between 26 and 80, in need of prosthetic treatment, and able to complete the questionnaire voluntarily. The questionnaire presented to the patients had two sections; the first included demographic and dentures-related variables, and the second included the OHIP-14 questionnaire. Differences in overall OHIP-14 scores after treatment about demographic and prosthesis-related factors were assessed using the Mann-Whitney U test/Kruskal Wallis test with a significance level of 0.05. Out of 108 participants, 65 were males, and 43 were females with an average age of 52 years with different prosthetic treatments (13.9 % fixed prostheses, 43.5 % removable partial, and 42.6 % complete dentures). 59.3 % brushed their teeth twice or more daily, and only 36.1 % checked them regularly. Comparison between the OHIP-14 items before and after treatment revealed that subjects exhibited improvement in all the domains. OHIP-14 scores did not differ significantly in terms of age, gender, and education after treatment. OHIP-14 score was considerably higher for patients with medical conditions (P = 0.007) and among complete denture wearers compared to patients with fixed prostheses (P = 0.025). Prosthetic treatment positively impacts oral health-related quality of life (OHRQoL), which improved after treatment, particularly in the social domain. There was an association between patients' medical condition, prosthesis type, and OHIP-14 score.

Evaluation of the quality of life and the satisfaction level after reconstruction with anterior iliac crest graft and implant-supported fixed prosthesis treatment

PURPOSE

To evaluate oral health-related quality of life (OHRQoL) and satisfaction levels related to treatment in patients who have complete implant treatment and prosthetic rehabilitation after anterior iliac crest grafting.

MATERIALS AND METHODS

Fifty-four patients (37 F, 17 M) with a total of 487 implants placed and implant-supported fixed prosthesis treatment completed were included in the study. OHIP-14OHIP-14 scale and satisfaction Likert scale questions were used to evaluate the OHRQoL and the satisfaction levels related to the treatment applied, respectively. To compare the outcomes, the significance test and the Mann-Whitney U-test were used. One-way analyses of variance and Kruskal-Wallis were used to assess the significance of differences among or between the groups.

RESULTS

The quality of life (QoL) was higher, and the mean OHIP-14 scores were lower in women, older patients, and cases with a longer follow-up period, recorded as 13.6 ± 10.3 (p: 0.263), 12.9 ± 11.3 (p: 0.079), and 11.8 ± 9.6 (p: 0.015*), respectively. Moreover, satisfaction levels of the patients related to the treatment were 83.3%.

CONCLUSIONS

The treatment of severely atrophic jaws with anterior iliac crest for the implant and prosthetic rehabilitation has a positive effect on the QoL. This effect has increased with time, and the satisfaction levels of the patients related to this procedure were high, and their expectations regarding this treatment were met at a high level.

A multicentric study to evaluate the treatment outcome and complications after oral rehabilitation with implant-supported hybrid prostheses

Background

As a newer modality of rehabilitation of completely edentulous patients, there is no conclusive evidence on which of the variants of hybrid prosthesis, namely acrylic teeth on a metal substructure or porcelain fused to metal teeth over on a metal substructure, is better in terms of treatment outcome, reduced mechanical complications, and better patient compliance.

Methods

Sixteen completely edentulous patients, both male and female, were selected from the OPD of the study centers during the study period. Group A: Eight patients rehabilitated by maxillary and mandibular hybrid prosthesis using a substructure of metal covered by acrylic teeth, which was screwed on the implants. Group B: Eight patients rehabilitated by maxillary and mandibular hybrid prosthesis using a substructure of metal covered by porcelain fused to metal teeth, which was screwed on implants. The patients were recalled at 3 months, 6 months, and 1 year following rehabilitation, and necessary clinical and radiological observations were made to evaluate the overall health and complications. Oral health-related quality of life was measured using the Oral Health Impact Profile (OHIP)-EDENT questionnaire before treatment and after rehabilitation. The same methodology, clinical procedures, and evaluation criteria were followed in all the study centers. The data obtained were then compiled and analyzed.

Results

None of the patients in group A or B showed any signs of need to remake. There was no statistically significant difference in proportions of cases showing signs of loosening of components, soft tissue overgrowth, breakage of acrylic, chipping of porcelain, and wear of teeth in both the groups. The amount of screw loosening, wear of prosthetic superstructure, and bone loss around implants were less (even though not statistically significant) in group A. Both the groups showed satisfactory esthetics. OHIP- EDENT evaluation gave completely satisfactory report after rehabilitation in both groups.

Conclusion

Both the types of complete rehabilitation, hybrid prosthesis of acrylic teeth on a metal substructure and hybrid prosthesis of porcelain fused to metal teeth on a metal substructure were successful and comparably reliable.

Changes in the teaching of prosthodontics adopted in the last academic course of the degree in Dentistry in Spain during the first period of the COVID-19 pandemic

OBJECTIVES

To investigate the impact of the COVID-19 pandemic in the teaching of prosthodontics, on the 5^th course of the Bachelor's degree in Dentistry in Spain.

METHODS

In June 2021, a two-section survey was submitted to the coordinators of prosthodontics of the 23 Spanish faculties of Dentistry. The first section was focused on the theoretical lessons, seminars, and clinical discussion sessions. The second part relied on the clinical teaching and the implemented preventive measures.

RESULTS

The response rate was 100%. By the end of the 2020-21 course, both the theoretical and practical teaching were replaced by online activities, returning to face-to face in 2021-22. While most participants preferred in-person seminars and clinical discussion sessions, concerning the theory, comparable percentages of professors chose either face-to-face or blended learning (BL). The students' satisfaction with BL is high, but they seem more attentive in-person. At the beginning of the pandemic, the most common emergency in prosthodontics was debonding. Overall, a low concern about cross-infection was noticed. The barrier measures were the mainly adopted for prevention.

CONCLUSIONS

Although the BL is appreciated in prosthodontics for theoretical lessons, face-to-face teaching appears to be the best option for seminars and clinical case discussions. The students are satisfied with BL.

CLINICAL SIGNIFICANCE

In the face of the COVID-19 pandemic, the Spanish faculties of Dentistry responded quickly to continuing offering quality education through an accelerated digitization process that has created a new paradigm. Detailed analyses of these changes may help establish plans to respond systematically to unforeseen emergencies.

Oral health-related quality of life of patients rehabilitated with fixed and removable implant-supported dental prostheses

Dental implants have become a mainstream treatment approach in daily practice, and because of their high survival rates over time, they have become the preferred treatment option for prosthetic rehabilitation in many situations. Despite the relatively high predictability of implant therapy and high costs to patients, patient perceptions of success and patient-reported outcome measures have become increasingly significant in implant dentistry. Increasing numbers of publications deal with oral health-related quality of life and/or patient-reported outcome measures. The aim of this paper was to provide an overview of the available evidence on oral health-related quality of life of fully and partially dentate patients rehabilitated with fixed and removable implant-supported dental prostheses. A comprehensive electronic search was performed on publications in English up to 2021. A selection of standardized questionnaires and scales used for the evaluation of oral health-related quality of life were analyzed and explained. The analysis encompassed three aspects: a functional evaluation of oral health-related quality of life, an esthetic assessment of oral health-related quality of life, and a cost-related evaluation of oral health-related quality of life for rehabilitation with dental implants. The data demonstrated that the preoperative expectations of patients markedly affected the outcomes perceived by the patients. As expected, reconstructions supported by implants substantially improved the stability of conventional dentures and allowed improved function and patient satisfaction. However, from a patient's perspective, oral health-related quality of life was not significantly greater for dental implants compared with conventional tooth-supported prostheses. The connection of the implants to the prostheses with locators or balls indicated high oral health-related quality of life. The data also suggest that patient expectation is not a good predictor of treatment outcome. In terms of esthetic outcomes, the data clearly indicate that patients' perceptions and clinicians' assessments differed, with those of clinicians yielding higher standards. There were no significant differences found between the esthetic oral health-related quality of life ratings for soft tissue-level implants compared with those for bone-level implants. Comparison of all-ceramic and metal-ceramic restorations showed no significant differences in patients' perceptions in terms of esthetic outcomes. Depending on the choice of outcome measure and financial marginal value, supporting a conventional removable partial denture with implants is cost-effective when the patient is willing to invest more to achieve a higher oral health-related quality of life. In conclusion, the oral health-related quality of life of patients rehabilitated with implant-supported dental prostheses did not show overall superiority over conventional prosthetics. Clinicians' and patients' evaluations, especially of esthetic outcomes, are, in the majority of cases, incongruent. Nevertheless, patient-reported outcomes are important in the evaluation of function, esthetics, and the cost-effectiveness of treatment with implant-supported dental prostheses, and should be taken into consideration in daily practice.

Treatment Plan and Challenges in Full-Mouth Rehabilitation of a Quadriplegic Patient: A Clinical Report

Spinal cord injuries lead to physical limitations, and the resulting levels of dependency and emotional distress have devastating consequences on individuals' oral health. A 46-year-old patient with incomplete quadriplegia due to a complicated medical history presented for prosthetic rehabilitation. The patient's ability and tolerance to be treated in the dental chair was assessed. Prosthetic treatment options were discussed considering his dependency on alternating caregivers. The final treatment plan involved restorative treatment, implant-supported crowns, an implant-supported fixed dental prosthesis and, in the upper jaw, an implant-supported overdenture to allow proper oral hygiene. The dental treatment sessions were performed with frequent interruptions in the dental chair, whereas the implants were placed under general anesthesia in the maxillo-facial surgery department. The final treatment plan resulted in a compromise between the prosthetic recommendation and the patient's wish. The decisive factor for choosing an implant-supported overdenture rather than an implant-supported fixed dental prosthesis in the upper jaw was the inability of the patient to maintain adequate hygiene measures by himself and his dependence on the caregivers. This clinical report demonstrates how special care dentistry can improve quality of life, even in people with severe physical and/or mental impairments. We would like to encourage dental professionals to provide high-quality care for patients with disabilities in particular, and this practice is in line with the requirements of the UN convention on the rights of persons with disabilities.

Fracture resistance of cantilevered full-arch implant-supported hybrid prostheses with carbon fiber frameworks after thermal cycling

OBJECTIVES

This in vitro study aimed to find the best combination of mesostructure and veneering materials for full-arch implant-supported hybrid prostheses (HPs) in terms of the fracture resistance (FR) of their cantilevers.

METHODS

Three groups (n = 5 each) of maxillary HPs were fabricated: Group-1 (CC-A, control): Co-Cr frameworks coated with acrylic resin; Group-2 (CF-A): carbon fiber veneered with acrylic resin; and Group-3 (CF-R): carbon fiber coated with composite resin. All specimens were submitted to 5,000 thermal cycles (5 °C - 55 °C, dwell time: 30 s), and subjected to a single cantilever bending test in a universal testing machine (crosshead speed: 0.5 mm/min) until failure. The fracture pattern was assessed using stereo microscope and SEM. The one-way ANOVA and Bonferroni tests were run (α= 0.05).

RESULTS

The FR yielded significant differences among the three groups (p< 0.001). CC-A samples reached the highest FR values (p ≤ 0.001), whereas both CF-A and CF-R HPs exhibited the comparably (p = 0.107) lowest FR. CC-A specimens failed cohesively (100%): mostly without chipping (80%). CF-A mesostructures were always broken at the connections of the distal implants. CF-R prostheses often failed adhesively (80%).

CONCLUSIONS

The HPs made of Co-Cr veneered with acrylic demonstrated the best mechanical behavior, being the only group whose 13-mm long cantilevers exceeded the clinically acceptable FR of 900 N. The HPs constructed with carbon fiber frameworks showed, additionally, more unfavorable fracture patterns.

CLINICAL SIGNIFICANCE

For HPs with cantilevers up to 13 mm, Co-Cr mesostructures coated with acrylic may represent the optimum combination of materials.

'Role of the modulating factors on the self-perceived OHRQoL of fully dentate subjects and wearers of screw-retained and cement-retained implant-supported FPDs: A cross-sectional study'

OBJECTIVES

This research aimed to compare the oral health-related quality of life (OHRQoL) between fully dentate subjects and edentulous patients wearing implant-supported fixed partial dentures (i-FPDs). The clinical conditions of both types of restorations were evaluated.

METHODS

Participants were assigned to: Group-1 (SR, n= 50): screw-retained i-FPD wearers; Group-2 (CR, n= 50): cement-retained i-FPD wearers; and Group-3 (ND, n= 50): dentate subjects with a healthy natural dentition (controls). Patients answered the OHIP-14sp and QoLIP-10 questionnaires. Data related to sociodemographics, prosthesis features, peri-implant status, complications, and subjective evaluations, were compiled. Potential modulators of the OHRQoL and the i-FPDs' clinical conditions were assessed using non-parametric tests (α= 0.05).

RESULTS

ND individuals were the least satisfied (OHIP-14sp; p< 0.001). Both prosthodontic groups reported similar levels of wellbeing, excluding the speaking difficulties, which were lower for SR wearers as shown by both scales (p= 0.001). The most discontented patients (OHIP-14sp) were: women (p= 0.022), under 65 years (p= 0.03), without partner (p< 0.001) and having a crown (p= 0.033). The level of education/schooling also affected the OHIP-14sp scores (p< 0.001). Implant mobility and peri-implantitis were more frequent among CR wearers (p-values= 0.008 and 0.05, respectively).

CONCLUSIONS

The OHRQoL of both prosthodontic groups was comparably higher than that of the dentate subjects, who were the most nonconformist. The self-perceived satisfaction was mainly modulated by sociodemographic factors.

CLINICAL SIGNIFICANCE

Overall, the retention system did not impact the OHRQoL, prosthetic problems, and subjective evaluations of i-FPD wearers. However, the cementation may increase the risk of peri-implant diseases.

Patient-Centered Treatment Outcomes with Full-Arch PEEK Rehabilitation Supported on Four Immediate or Conventionally Loaded Implants. A Randomized Clinical Trial

This study aims to assess the treatment outcomes (functional and subjective) of full-arch fixed hybrid rehabilitations made of PEEK (poly-ether-ether-ketone) with milled crowns of nano-filled composite (NFC) supported on four to six implants. In this randomized clinical trial, 34 edentate patients in the upper and/or the lower jaws were treated with the fixed hybrid dentures. In 16 patients (47.1% of the sample), the implants were loaded immediately (IL) by means of a provisional fixed rehabilitation made of PMMA (polymethylmethacrylate) screwed on Multi-Unit (MU) abutments connected after emplacement of the implant; however, in the counterparts (n = 18) these MU abutments were covered by healing caps and were left unloaded during two months (conventional loading protocol—CL), when all patients received a fixed hybrid PEEK-NFC rehabilitation on the upper and/or the lower jaw. Treatment outcomes were assessed 12 months after prostheses delivery. Functional outcomes were calculated according to masticatory performance, estimated by mixing ability tests of two colored chewing gums after ten chewing strokes, by the occlusal force/area recorded by pressure-sensitive sheets, and by electromyography of masseters and temporal muscles at maximum biteforce. The subjective outcomes of the treatment were assessed using both the oral satisfaction scale (visual analog scale) and the Spanish version of the Oral Health Impact Profile (OHIP-20). The findings of the present study showed that treatment with fixed PEEK-NFC hybrid prostheses significantly improved the masticatory performance, bite force, occlusal pattern, quality of life, and satisfaction, with the IL group being those with significantly higher occlusal bite forces and greater satisfaction in comparison with CL group. It should be concluded that PEEK-NFC hybrid prostheses can improve several patient-centered outcomes and that loading protocol significantly affects the patient’s self-rated satisfaction.

'Differences in self-perceived OHRQoL between fully dentate subjects and edentulous patients depending on their prosthesis type, socio-demographic profile, and clinical features'

OBJECTIVES

This observational cross-sectional study aimed to evaluate and compare the oral health-related quality of life (OHRQoL) and clinical performance between dentate subjects and edentulous patients restored with conventional dentures or implant overdentures.

METHODS

85 edentulous patients were grouped as follows: Group-1 (CD): conventional denture wearers (n= 42), and Group-2 (IO): implant-retained overdenture wearers (n= 43). For the OHRQoL comparisons, a control group of subjects with a healthy natural dentition (Group-3, ND; n= 50) was included. Participants completed three validated questionnaires (OHIP-14sp, OHIP-20sp, and QoLIP-10). Socio-demographic data, prosthesis-related factors, clinical condition of the mouth, and patient subjective evaluations, were gathered. Descriptive and non-parametric probes were run (α= 0.05).

RESULTS

The ND group was the most unsatisfied (OHIP-14sp; p≤ 0.001). The OHIP-20sp attributed significantly worse Psychological disability (p= 0.029) and Handicap (p= 0.027) to CD wearers when compared to IO wearers. The CD group showed the significantly highest need for relining (p= 0.041), and the lowest retention (p= 0.011). The OHIP-14sp disclosed a significantly worse OHRQoL for those volunteers who had a job (p= 0.003), a basic education instead of a secondary one (p= 0.022), and no partner (p= 0.006).

CONCLUSIONS

The overall OHRQoL was comparable for both prosthodontic groups, being modulated by socio-demographic and prosthesis-related features. Nonetheless, CD wearers presented prosthetic complications more frequently.

A Seven-year Follow-up Study of Patient Satisfaction with Three-implant-retained Mandibular Overdentures

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period. MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction. RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p < 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months. CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

Fabrication of a complete-arch implant-supported fixed interim prosthesis by using a cone beam computed tomography digital scan for a patient with primordial dwarfism: A dental technique

A complete-arch implant-supported interim prosthesis was fabricated from a cone beam computed tomography digital scan of the implant abutments for a patient with primordial dwarfism. The patient presented with limited mouth opening, which hindered the use of a conventional impression technique. The described technique provided an alternative digital procedure to obtain a virtual implant definitive cast.

Nonmalignant Oral Disease--Specific Dental Patient-Reported Outcome Measures for Adult Patients: A Systematic Review

OBJECTIVES

Dental patient-reported outcome measures (dPROMs) can be differentiated into outcome measures for all oral diseases, so-called disease-generic dPROMs, and measures for specific oral diseases, so-called disease-specific dPROMs. The aim of this systematic review was to identify the psychometrically validated nonmalignant disease-specific dPROMs for adult patients and the dental patient-reported outcomes (dPROs) they measure.

METHODS

This systematic review searched Ovid MEDLINE, Embase, PsycINFO, and the Cochrane databases along with hand searching, through July 28, 2020, to identify original articles of English language, multi-item dPROMs for adult dental patients with a specific oral disease, condition, or oral manifestations of systemic diseases. We analyzed the questionnaires for content commonalities, the reference or recall period, and the dimensionality.

RESULTS

We retrieved 4228 unique references and identified 34 questionnaires; of which, 31 questionnaires captured impacts from oral diseases or conditions and three from oral manifestations of systemic diseases. All questionnaires together contained 102 dPROMs, measuring 75 dPROs. Oral health-related quality of life was a broader dPRO, which was measured by 24 dPROMs. The 74 narrower dPROs were measured by 78 dPROMs. The dPRO names suggested that essentially four dPROs were measured: Oral Function (N = 19), Orofacial Pain (N = 7), Orofacial Appearance (N = 11), and Psychosocial Impact (N = 37).

CONCLUSIONS

Many psychometrically validated tools (N = 102) are available to measure the impact of specific nonmalignant oral disease on patients. While these tools intend to measure the particular patient-perceived impact profile of the oral disease, all tools measure in essence only four, more general concepts - the dimensions of oral health-related quality of life.

Clinical and satisfaction outcomes of using one or two dental implants for mandibular overdentures: preliminary short-term follow-up of a randomized clinical trial

Objective

This randomized clinical trial aimed to evaluate the marginal bone loss and peri-implant aspects in patients with mandibular overdentures retained by one or two implants and assess patient satisfaction, prosthesis-related clinical outcomes, and masticatory efficiency.

Methods

Patients from the School of Dentistry of the University of Passo Fundo (UPF) with lower conventional complete dentures dissatisfied with prosthetic retention were selected. Eighteen patients were analyzed and divided into randomized treatment groups: GA, installation of one implant in the midline of the mandibular symphysis (8 patients), and GB, installation of two implants in the lower canine region (10 patients). Implant survival and prosthetic maintenance were assessed by clinical and radiographic examinations performed 6 months after implant placement and 3 months after loading. Finally, the masticatory efficiency of the prostheses was evaluated with the QoLIP-10 (Quality of Life with Implant-Prostheses) questionnaire, and the degree of patient satisfaction used the visual analog scale (VAS).

Results

Regarding the esthetic satisfaction of the patients, there was no statistical difference between the two groups studied (p = 0.680). Patients who received two implants presented easier chewing (p = 0.049) and a lower average number of prosthesis maintenance. There was no difference between the groups regarding peri-implant bone resorption 3 months after the use of prostheses.

Conclusions

The use of two dental implants showed higher masticatory ability and lower need for maintenance appointments when compared with one implant in mandibular overdentures but did not affect peri-implant aspects and patient satisfaction. The treatment using one implant was effective for the aspects evaluated, but further clinical studies are required on the subject.

Evaluation Tools for Assistive Technologies: A Scoping Review

OBJECTIVE

Assistive technologies (ATs) support independence and well-being in people with cognitive, perceptual, and physical limitations. Given the increasing availability and diversity of ATs, evaluating the usefulness of current and emerging ATs is crucial for informed comparison. We aimed to chart the landscape and development of AT evaluation tools (ETs; ATETs) across disparate fields in order to improve the process of AT evaluation and development.

DATA SOURCES

We performed a scoping review of ATETs through database searching of MEDLINE, Embase, CINAHL, HaPI, PsycINFO, Cochrane Reviews, and Compendex as well as citation mining.

STUDY SELECTION

Articles explicitly referencing ATETs were retained for screening. We included ETs if they were designed to specifically evaluate ATs.

DATA EXTRACTION

We extracted 5 attributes of ATETs: AT category, construct evaluated, conceptual frameworks, type of end user input used for ATET development, and presence of validity testing.

DATA SYNTHESIS

From screening 23,434 records, we included 159 ATETs. Specificity of tools ranged from single to general ATs across 40 AT categories. Satisfaction, functional performance, and usage were the most common constructs of 103 identified. We identified 34 conceptual frameworks across 53 ETs. Finally, 36% incorporated end user input and 80% showed validation testing.

CONCLUSIONS

We characterized a wide range of AT categories with diverse approaches to their evaluation based on varied conceptual frameworks. Combining these frameworks in future ATETs may provide more holistic views of AT usefulness. ATET selection may be improved with guidelines for conceptually reconciling results of disparate ATETs. Future ATET development may benefit from more integrated approaches to end user engagement.

Eleven-year follow-up of reconstruction with autogenous iliac bone graft and implant-supported fixed complete denture for severe maxillary atrophy: A case report

RATIONALE

The iliac bone graft procedure is one of the treatment options for individuals with extremely resorbed alveolar bones. An autogenous block bone graft can allow the use of an implant-supported fixed dental prosthesis, rather than conventional removable dentures, by completely edentulous patients. However, the iliac bone graft technique is an invasive procedure and should be carefully selected based on its long-term clinical results. This case report describes 11-year long-term outcomes for implant-supported complete denture on the grafted iliac bone.

PATIENT CONCERNS

A 68-year-old Asian man was referred for oral rehabilitation with fixed dental prostheses. The patient had been unsatisfied with his removable dental prostheses in masticatory performance.

DIAGNOSIS

Radiographical examination revealed severely atrophied maxilla.

INTERVENTIONS

The atrophied maxilla was reconstructed with an iliac block bone graft, after which an implant-supported fixed complete denture was placed.

OUTCOMES

During 11 years of follow-up, several prosthetic and mechanical complications were encountered. Nevertheless, no biological complications were observed. Marginal bone levels around the implants were well-maintained on the radiographs after 11 years of prosthetic use.

LESSONS

Iliac bone graft can be chosen as a predictable treatment option that allows patients with extremely atrophic maxilla to use a fixed dental prosthesis instead of a removable denture.

The effect of implant prosthesis complications on patient satisfaction

STATEMENT OF PROBLEM

How complications regarding implant prostheses affect patient satisfaction and oral health-related quality of life (OHRQoL) is unclear.

PURPOSE

The purpose of this retrospective study was to compare patient satisfaction with implant restorations in patients with or without a history of complications. These data were used to determine whether implant prosthesis complications affected self-reported OHRQoL.

MATERIAL AND METHODS

Data were gathered from 176 edentulous and partially dentate patients who had received implant prostheses consisting of implant-supported crowns, implant-supported overdentures, and screw-retained fixed dental prostheses (FDPs) in predoctoral and postdoctoral clinics between January 1, 2010, and December 31, 2014. Demographics and complications were self-reported by means of a survey. Patients rated their OHRQoL using the Quality of Life with Implant-Prostheses (QoLIP-10) questionnaire. Means were compared by using a 1-way ANOVA to compare the variables of prosthesis complications, sociodemographic data, and patient satisfaction. Significantly different variables were further evaluated using a post hoc Tukey-Kramer Honestly Significant Different (HSD) test (α=.05).

RESULTS

Statistically significant differences in patient satisfaction were found related to prosthesis complications, gender, and marital status. The most common complication for implant-supported crowns was screw loosening. For implant-supported overdentures and screw-retained FDPs, the most common complication was repair of the prosthesis. Those who had experienced complications reported lower OHRQoL scores than those who had not. Women and widows/widowers overall reported lower OHRQoL scores. The OHRQoL scores of women with and without prosthesis complications were not statistically different (P=.073). No significant differences were found relative to age (P=.937) or education (P=.302). Patients without complications with implant-supported crowns reported the lowest satisfaction because of oral hygiene difficulties. The lowest satisfaction in patients with complications of implant-supported overdentures and screw-retained FDPs was related to worry/concern because of problems with the implant prosthesis.

CONCLUSIONS

The results of this survey suggest that patients who experience complications with an implant prosthesis report a lower OHRQoL score than those who do not. Future studies are needed to evaluate patient satisfaction by comparing prosthesis complications with and without implants to determine whether patients who have had complications with implant prostheses are more satisfied than those who have experienced complications with conventional prostheses.

Patient-Reported Outcome Measures for Adult Dental Patients: A Systematic Review

OBJECTIVES

Patient-reported outcomes (PROs) are used beside disease-oriented outcomes (eg, number of teeth, clinical attachment level) to better capture the impact of diseases or interventions. To assess PROs for dental patients (dPROs), dental PRO measures (dPROMs) are applied. The aim of this systematic review was to identify generic dPROMs for adult patients and the dPROs.

METHODS

This systematic review searched the MEDLINE, Embase, and PsycINFO databases along with hand searching, through December 2017, to identify English-language, multi-item dPROMs that are oral health generic, that is, they are applicable to a broad range of adult patients.

RESULTS

We identified 20 questionnaires that contained 36 unique dPROs. They were measured by 53 dPROMs. dPRO names (N = 36) suggested they could be grouped into four dPRO categories: (1) Oral Function (N = 11), Orofacial Pain (N = 7), Orofacial Appearance (N = 3), and Psychosocial Impact (N = 14), as well as an additional dPRO that represented perceived oral health in general. Only eight questionnaires had a specific recall or reference period. dPROM's score dimensionality was only investigated in 13 of the 20 questionnaires.

CONCLUSIONS

The identified 36 dPROs represent the major aspects of an adult dental patient's oral health experience; however, four major dPRO categories, that is, Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact, summarize how patients are impacted. If multi-item, oral health-generic dPROMs are to be used to measure patients' suffering, the 53 dPROMs represent current available tools. Limitations of the majority of these dPROMs include incomplete knowledge about their dimensionality, which affects their validity, and an unspecified recall period, which reduces their clinical applicability.

Combination of straight and tilted implants for supporting screw-retained dental prostheses in atrophic posterior maxillae: A 2-year prospective study

OBJECTIVES

To evaluate the two-year survival rate (SR) and marginal bone loss (MBL) of fixed dental prostheses (FDPs) supported by straight (S) and tilted (T) implants under the influence of diverse study variables.

METHODS

A prospective investigation comprising 21 patients provided with a total of 27 maxillary screw-retained restorations fixed to 70 dental implants was developed. Two groups of implants were considered depending on their inclination with respect to the occlusal plane: Group 1 (S, n=37): straight/axial implants and Group 2 (T, n=33): tilted/angled fixations. Each FDP was supported by a combination of S and T implants. SR and MBL were assessed at the time of loading and two years after surgery. Patient-, surgical- and/or rehabilitation-related information was gathered. Data were statistically analysed at the α=0.05 significance level.

RESULTS

After 24 months, a 100% SR was achieved and the MBL of S and T implants were statistically similar. T implants located in the molar region showed lower MBL than did those replacing premolars (p=0.031).

CONCLUSIONS

Upright and angled fixations inserted at posterior maxillary areas resulted in comparable survival rates and peri-implant MBL after two years. The marginal bone resorption around tilted implants depended on their location.

CLINICAL SIGNIFICANCE

Screw-retained restorations fixed to straight and tilted implants seem to be a safe treatment option in posterior atrophic maxillae.

Prosthodontic treatment of a retrognathic edentulous maxilla demonstrating limited interarch distance: 3.5-year results with fixed and removable implant prostheses

The prosthodontic treatment of patients with a retrognathic edentulous maxilla should consider the restoration of the lower facial profile and access for oral hygiene. This clinical report describes prosthodontic treatments of a patient with edentulism who presented with repeated fractures of the denture teeth of a maxillary implant-supported complete fixed dental prosthesis (ICFDP) and a mandibular implant-supported overdenture. Considerable plaque accumulation was noted on the ICFDP, which was replaced with an open palatal design implant-supported overdenture. However, the patient experienced difficulty managing the 2 removable prostheses. The patient's mandible was eventually restored with a milled titanium alloy framework ICFDP with metal occlusal surfaces. This combined approach of fixed and removable prostheses was stable at 3.5-year follow-up appointment, without compromising the patient's oral hygiene or comfort.

Is a Fixed Hybrid Prosthesis with Distal Cantilever Appropriate for Maxillofacial Defects? A Report of Two Patients

The most important objectives in restoring the maxillofacial patient are the restoration of function and psychological improvement through esthetics. Acquired maxillary and mandibular defects due to significant trauma or surgery represent a major challenge for the clinician and patient. Dental implant-retained prostheses represent a well-documented and reliable treatment option and can also help patients with maxillofacial defects by eliminating denture instability and improving function. Full-arch fixed dental hybrid prostheses provide functional and psychological advantages and also reduce the load on vulnerable soft and hard tissues in the reconstruction area. Two clinical reports are presented describing the prosthetic rehabilitation using dental implant-supported fixed hybrid prostheses with clinical and radiographic follow-up of 3 years.

Impact of fixed implant supported prostheses in edentulous patients: protocol for a systematic review

INTRODUCTION

Edentulism is a debilitating and irreversible condition described as the 'final marker of disease burden for oral health'. Therapy with dental implants is being used on a large scale to replace missing teeth and to rehabilitate edentulous patients with overdentures and implant supported fixed dentures as a method of solving the problem of instability and lack of retention associated with conventional removable prostheses. Fixed implant supported prostheses are an alternative for implant rehabilitation treatment that allow patients to have new fixed teeth. They can be indicated in partial or total edentulous patients, and they can replace single teeth, or teeth and supporting tissues (hybrid prosthesis). They overcome the limitations of conventional dentures, increasing stability and retention, providing functional and psychological advantages for the patients.

METHODS AND ANALYSIS

We will electronically search for randomised controlled trials evaluating the effects of fixed implant supported prostheses in edentulous patients in the following databases: Pubmed/MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. We will also try to obtain literature screening references of included studies, searching for trial protocols in the WHO International Clinical Trials Registry Platform, reviewing International Team for Implantology conference proceedings and searching for non-published studies through Open Gray. Two researchers will independently undertake selection of studies, data extraction and assessment of the quality of the included studies. Data synthesis and subgroup analyses will be performed using special Review Manager software. Data will be combined in a meta-analysis using a random effects model.

RESULTS

The results will be presented as risk ratios for dichotomous data, and as mean difference or standardised mean difference for continuous data.

ETHICS AND DISSEMINATION

No ethics approval is considered necessary. The results of this study will be disseminated via peer reviewed publications and social networks.

Relationship between impact of maxillary anterior fixed prosthodontic rehabilitation on daily living, satisfaction, and personality profiles

STATEMENT OF PROBLEM

Personality profiles may affect the impact of dental treatment on daily living and patient satisfaction.

PURPOSE

The purpose of this clinical trial was to evaluate the impact of maxillary anterior fixed prosthodontic rehabilitation on daily living and the satisfaction of patients and to investigate its relationship with personality profiles.

MATERIAL AND METHODS

Fifty-nine participants (25 men and 34 women; mean age 32.4 ± 6.9 years) received maxillary anterior partial fixed dental prostheses. The clinical success of the prostheses was evaluated following specific criteria. The Dental Impact on Daily Living (DIDL) questionnaire was used to measure satisfaction with the prostheses and their impact on daily living. The Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI) was used to measure patients' personality profiles. The paired sample t test was used to compare satisfaction and personality scores before and after treatment (α=.05).

RESULTS

Participants' total satisfaction and their satisfaction with appearance, pain tolerance, oral comfort, general performance, and eating improved after treatment (P<.05). Before treatment, women were less satisfied with general performance (P=.047) and scored higher on the Neuroticism score (P=.039); however, after treatment, women were more satisfied with appearance (P=.004). Age and sex had no significant correlation with personality profiles after treatment. Before treatment, Neuroticism, Openness, and Conscientiousness scores were associated with dental satisfaction and impact on daily life (P<.05). After treatment, Neuroticism, Openness, and Extraversion scores were associated with dental satisfaction and impact on daily life (P<.05).

CONCLUSIONS

Patient satisfaction with their oral condition improved after partial fixed dental prosthetic rehabilitation in the maxillary anterior esthetic zone. Psychological profiles (Neuroticism, Extraversion, Openness, and Conscientiousness) may be involved in and explain the impact on daily living and the degree of patient satisfaction with their prostheses.

Complete oral rehabilitation of a patient with hereditary gingival fibromatosis: a clinical report

Hereditary gingival fibromatosis is a rare disease that has several debilitating oral and psychological manifestations, especially with young children and adolescents. The complexity of the treatment as well as the timing relative to the growth and maturation of the patient present a challenge. Few treatment options have been reported in the literature. This clinical report presents a multidisciplinary approach to treating a young patient with hereditary gingival fibromatosis by using implant-supported prostheses. The treatment steps and its outcome are discussed.

Systematic review of short- (5-10 years) and long-term (10 years or more) survival and success of full-arch fixed dental hybrid prostheses and supporting implants

OBJECTIVES

The aim of this systematic review was to investigate the short-term (5-10 year mean follow-up) and long-term (10 year or more) survival and success of fixed full arch dental hybrid prosthesis and supporting dental implants.

METHODS

Studies reporting interventions with full-arch fixed dental hybrid prostheses were identified by searching PubMed/Medline (NCBI), Web of Science (Thomson Reuters), the Cochrane Register of Controlled Clinical Trials (EBSCO), and Dentistry and Oral Sciences Source (DOSS; EBSCO) from the earliest available dates through July 17, 2013. Through a series of review process by two examiners, potentially qualifying studies were identified and assessed with respect to the inclusion criteria.

RESULTS

A total of 18 studies were included for the quality assessment and the systematic review. Within the limitation of available studies, high short-term survival rates of full arch fixed dental hybrid prostheses (93.3-100%) and supporting implants (87.89-100%) were found. However, the availability of studies investigating long-term outcomes seemed scarce. Furthermore, the included studies were subjected to potential sources of bias (i.e. publication, reporting, attrition bias).

CONCLUSIONS

Despite seemingly high short-term survival, long-term survival of implant supported full arch fixed dental hybrid prosthesis could not be determined due to limited availability of true long-term studies. Although it may be a valuable option for a patient with a completely edentulous ridge(s), the strategic removal of teeth with satisfactory prognosis for the sake of delivering an implant supported full-arch dental hybrid prosthesis should be avoided.

The burden of osteoarthritis: development and validation of a new assessment tool (BONe'S)

OBJECTIVE

To develop and validate a specific individual burden questionnaire, BONe'S (Burden of Osteoarthritis New Scale), assessing osteoarthritis (OA) patients in the broadest sense.

RESEARCH DESIGN AND METHODS

Items included in BONe'S were identified by literature review, and patient/healthcare practitioner interviews, and refined via item reduction and exploratory factor analysis (EFA). Internal consistency was calculated using Cronbach's α; concurrent validity was assessed by calculating the correlation between BONe'S and the Short Form (SF)-12 Health Survey and Psychological General Well-Being Index (PGWBI). Discriminant validity was analyzed by age, gender and number of OA locations.

RESULTS

From an initial list of 56 items, the final BONe'S questionnaire consisted of 20 questions (5 dimensions) based on EFA. BONe'S was evaluated in patients with OA (n = 200; mean age 69.4 ± 7.0 years, 86% of patients aged >60 years, 91.5% women). BONe'S demonstrated excellent internal coherence (Cronbach's α: 0.86). Individual BONe'S dimensions correlated well with the overall BONe'S score (highest: 'Independence' [r = 0.91]; lowest: 'Hygiene & Beauty' [r = 0.56]), and to each other dimension, and also correlated well (inversely) with the SF-12 and, to a slightly lesser extent, the PGWBI. The only exception was 'Budget', but this dimension was important and relevant in the subpopulation of active OA patients (r = 0.40). The mean BONe'S score for subjects with one or two affected joints was significantly lower than for subjects with three or more affected joints. The BONe'S score also differed according to gender and age. The original French BONe'S has also been adapted (linguistically and culturally) to English, Russian and Portuguese. Limitations include the fact that BONe'S was developed in a predominantly female population, in patients receiving a pharmacological intervention, has not been evaluated in a large population and has not been compared with other OA tools, including WOMAC, Lequesne and KOOS.

CONCLUSION

The BONe'S questionnaire is a short (20-item) validated tool for evaluating the specific individual burden of OA in a holistic manner.
