J Prosthet Dent 2021; 129:748-753. [PMID: 34429196 DOI: 10.1016/j.prosdent.2021.07.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 07/12/2021] [Accepted: 07/12/2021] [Indexed: 11/26/2022]
Abstract
STATEMENT OF PROBLEM Bilateral balanced occlusion has been advocated over nonbalanced occlusion for improved removable complete denture stability and function. However, assessments of quality of life and patient satisfaction studies between the 2 occlusion schemes are lacking. PURPOSE The objective of this parallel randomized control trial was to determine the difference in quality of life and patient satisfaction between the nonbalanced and bilaterally balanced occlusal schemes. MATERIAL AND METHODS Sixty participants were included in the parallel randomized control trial of nonbalanced and bilaterally balanced complete dentures. Thirty were recruited into each group with definitive inclusion and exclusion criteria as per the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Quality of life was estimated from the oral health quality of life (Oral Health Impact profile) for edentulous patients questionnaire, and patient satisfaction was analyzed from a visual analog scale. The estimation was made at 0, 3, and 6 months after denture insertion. The data were statistically analyzed with the Friedman, Mann-Whitney, and t test (α=.05). RESULTS The mean ±standard deviation Oral Health Impact profile score was 60.81 ±8.87 for nonbalanced dentures and 64.12 ±8.98 for bilaterally balanced dentures. The mean ±standard deviation visual analog scale score was 2.84 ±0.28 for nonbalanced dentures and 2.90 ±0.31 for bilaterally balanced dentures. The Mann-Whitney and t test indicated nonsignificant differences between the 2 groups and at different time intervals for Oral Health Impact profile and visual analog scale scores (P>.05). CONCLUSIONS The study detected no significant differences between the 2 occlusal schemes in quality of life or patient satisfaction.

Abstract
PURPOSE Multiple clinical studies have been published comparing different philosophies of complete denture occlusion and different types of denture teeth. However, it is unclear whether comparable data are available for occlusal schemes used with removable partial dentures (RPDs). Therefore, this review investigated the dental literature related to occlusal schemes for RPDs. MATERIALS AND METHODS A PubMed search of English language articles was performed using the term "removable partial denture, occlusion" with 765 results. When the term "occlusion in removable partial prosthodontics" was used there were 784 results. Seventy-four articles were identified using the different search term of "RPD, occlusion" while use of the term "occlusal scheme, with removable partial dentures" listed 18 publications. The term "removable partial denture, occlusion, literature reviews" produced 38 potential publications related to the topic. Using the term "removable partial denture occlusion systematic review" resulted in 2 citations. Using the term "RPD occlusion literature review" resulted in one foreign language manuscript whereas using the term "RPD occlusion systematic review" resulted in one article unrelated to dentistry. The term "clinical studies of RPD occlusion" produced 5 results with none related to the topic. There were 23 results using the term "clinical studies of removable partial denture occlusion" with one potentially related to RPD occlusal schemes. RESULTS A review of the titles and abstracts revealed 12 articles that appeared to contain specific information about the occlusal scheme used with RPDs. Following a detailed review of those publications, only 4 contained recommendations for RPD occlusion and were included in this review. The available information regarding the recommendations for occlusal schemes in these articles was based on expert opinion. A decision was made to include a hand search of 9 textbooks containing varying amounts of information related to occlusal schemes for RPDs, but no evidence-based references related to RPD occlusal schemes were found in the textbooks. Since this entire review is based on expert opinion, no attempt was made to critique the opinions expressed by these authors but rather to present their perspectives for evaluation by readers. CONCLUSIONS The occlusion developed with RPDs should be physiologically harmonious, allowing the supporting structures to remain in a good state of health with functional stress distributed among all the occluding teeth. Multiple authors indicate the occlusion in maximum intercuspation/centric occlusion should incorporate bilateral posterior contacts with no deflective occlusal contacts. When most occlusal contacts on natural teeth are missing, it has been proposed that extension base RPDs have their occlusal contacts developed in centric occlusion. Regarding eccentric occlusal relationships, a balanced occlusal scheme has been recommended by multiple authors with one author advocating use of a lingualized balanced. An anterior guided (canine-protected) occlusion has also been recommended when the canines are present and not periodontally compromised. When RPDs oppose a complete denture, several authors indicate a bilateral balanced occlusion should be used to help stabilize the complete denture.

Comparison of Canine-Guided Occlusion with Other Occlusal Schemes in Removable Complete Dentures: A Systematic Review. PROSTHESIS 2021.

Abstract
Choosing an adequate occlusion is challenging during the construction of artificial dentures, and critical for patient satisfaction. However, there is no conclusive evidence to support which occlusal design is more appropriate. The aim of this systematic review was to evaluate canine-guided occlusion in comparison to other occlusal schemes in removable complete denture wearers. The review was conducted according to the Preferred Reported Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. An extensive search was carried out on (PubMed (National Library of Medicine)), Scopus (Elsevier), Cochrane collaboration (Wiley), Science Direct (Elsevier) and Europe PMC (European Bioinformatics Institute). English and non-English studies were identified using keywords on canine-guided occlusion, denture occlusion, dental occlusion and artificial occlusal schemes. Out of 1759 articles searched, 18 were selected based on the inclusion criteria. The included studies were interpreted for the descriptive analysis for the calculation of occlusal schemes, occlusion assessment parameters, the outcome of the occlusal schemes and types of removable prosthesis used. The systematic analysis of occlusal schemes revealed that canine-guided occlusion is viable compared with other occlusal designs in terms of patient satisfaction, mastication, retention, esthetics, phonetics, oral-health-related quality of life and muscle activity. The type of occlusal scheme influences the complete denture patient’s’ masticatory efficiency, satisfaction, retention, phonetics and esthetics. Nevertheless, physical, physiological, mechanical and psychological factors play a vital role in the success of removable complete dentures. The canine-guided occlusal scheme is preferred because of its simplicity, less time consumption, good masticatory performance, ease of fabrication and modification into bilateral balanced occlusion if required. Further studies are required to reduce the controversies related to jaw relations, gnathology and occlusal schemes in complete dentures.

Abstract
PURPOSE The occlusal scheme required for an edentulous patient is controversial. The purpose of this Best Evidence Consensus Statement was to evaluate the existing complete denture literature related to occlusal schemes. MATERIALS AND METHODS A literature search was limited to Meta-analyses, Systematic Reviews (SR), Randomized Controlled Studies (RCT) and Clinical Trials. Key Words were: Complete dentures, occlusion, harm; Complete dentures, occlusion alveolar bone loss; Complete dentures, occlusion, stability; Complete dentures, occlusion. Additional related articles were culled from the authors' library and reference lists in the articles found in the PubMed searches. RESULTS Of the 165 articles that met the initial search criteria, 34 related to the focus questions and were evaluated and rated. CONCLUSIONS There is strong support that the average denture patient, with good residual ridges and no neuromuscular problems, will function adequately with a properly fabricated complete denture regardless of the occlusal scheme. There is neither strong support for or against bilateral balanced occlusal schemes as it relates to patient satisfaction, preference or chewing ability. There is some support for increased alveolar bone loss with complete dentures that have a non-balanced occlusion. There is a need for bilateral balanced occlusal schemes for patients presenting with loss of stability and retention as a result of their presenting conditions (PDI III and IV).

Abstract
Aim: The aim of the study is to acquire evidence for the choice of occlusion with anatomic/modified anatomic teeth in complete denture prosthesis. Settings and Design: Systematic review following PRISMA guidelines. Materials and Methods: The study reviewed original articles on various occlusal schemes bilateral balance occlusion (BBO), lingual occlusion (LO), Canine guided occlusion (CG), posterior group function occlusion (PGFO) have been applied to the complete dentures and were analyzed for the objective or subjective or both evaluations. The data were collected in standard format with the needed information such as year of publication, type of study, occlusal schemes compared, test methodology used, sample size for experiment and control, assessment of retention, stability, and other factors which determine the quality of life and period of follow-up. The risk of bias was calculated using tools RoB2.0 and robvis. At all stages, the inclusion and exclusion of studies were discussed among the reviewers. Statistical Analysis used: Due to the heterogeneity in the data of the included studies no statistical analysis was used. Results: Of the 1896 articles screened only 17 studies were included in the systematic review. These were discussed amongst the reviewers regarding the various occlusion schemes used. The subjective and objective criteria used in the studies was tabulated separately. They were then analyzed for the risk of bias using the robvis 2 tool. Conclusion: No scheme is more superior to the other with the anatomic tooth forms. The use of alternative unbalanced schemes produces a similar satisfactory clinical outcome. The ridge classification also has a significant role to play in the preference for an occlusal scheme.

Abstract
The search of an adequate occlusal scheme that maximizes dentures’ stability and patients’ satisfaction is an ultimate objective in every complete prosthodontic treatment. Many studies compared occlusal schemes in terms of retention, comfort and masticatory performance. The purpose of this article is to review literature about different occlusal schemes related to complete dentures’ stability and edentulous patients’ satisfaction, in order to select the most appropriate occlusal scheme. Thus, an electronic search was performed from PubMed (MEDLINE), Scopus, Cochrane, Google Scholar and Sciencedirect databases. 65 articles were identified of which 56 were selected to compose the present article. Within the limitations of this review, it has been concluded that edentulous patients prefer anatomic occlusal schemes to non-anatomic teeth. Furthermore, canine guidance seems to be efficace in terms of chewing comfort and dentures’ retention, as well as lingualized occlusion. However, bilateral balanced occlusion does not confer a long-term masticatory performance and satisfaction to edentulous patients.

Abstract
Occlusal scheme is a controversial topic that has been linked to patient satisfaction with conventional complete dentures (CCDs). This study aimed to compare the patient satisfaction with CCDs with four different occlusal schemes namely the lingualised occlusion (LO), buccalised occlusion (BO), fully bilateral balanced occlusion (FBBO) and partially group function occlusion (PGFO). In this clinical study, new CCDs were made for 121 patients; out of which, 97 patients (mean age of 57.87 ± 9.5 years) completed the 1-year follow-up. The CCD wearers were followed up at 1 month, 3 months and 1 year after CCD delivery. Data were collected via an interview and recorded in a checklist by a blinded examiner. The checklist included the demographic variables, the 19-item version of Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT), and seven 100-mm line visual analogue scales (VASs) to assess the items related to patient satisfaction. The Kruskal-Wallis and Friedman tests followed by post hoc tests were used to compare the variables among the 4 groups and between the 3 follow-ups. P-value ≤ .05 was considered statistically significant for all tests. The patients with BO presented higher satisfaction scores for comfort, stability and retention at the 1-year follow-up compared with PGFO. Both PGFO and FBBO groups had higher physical pain scores compared with BO and LO. The psychological discomfort scores of FBBO group were significantly higher than those in LO group. Pairwise comparisons revealed no significant differences in the general patient satisfaction and total OHIP-EDENT scores between the 4 groups. For most items, within-group analysis showed significant improvement of the satisfaction scores and reduction of domain scores over time.

Abstract
OBJECTIVES Previous studies have often discussed occlusal concepts for complete dentures without formulating a recommendation. Various options are available, the most common ones being canine-guided occlusion (CGO) and bilateral balanced occlusion (BBO). We designed a prospective randomized study to compare these two schemes with the goal of formulating a recommendation. MATERIALS AND METHODS Forty patients could be evaluated. In a crossover design, they were randomized to a CGO>BBO group and a BBO>CGO group, each starting out by wearing their dentures with the first occlusal scheme for 3 months, followed by a first investigator- and patient-centered assessment. Then, each patient was transitioned to the other occlusal scheme by replacing the denture setup in the dental laboratory, followed by another 3 months of intraoral use and a second assessment. Wilcoxon-Mann-Whitney and marginal homogeneity tests were used for statistical analysis. RESULTS All statistically significant differences favored the CGO concept. Based on patient ratings, the CGO>BBO group preferred its esthetics (p = 0.02) and the BBO>CGO group its mandibular retention (p = 0.05), phonetics (p = 0.03), and masticatory function (p = 0.01). Based on investigator assessments, maxillary denture retention was found to significantly improve among the BBO>CGO patients after transition to CGO (p = 0.01). CONCLUSIONS Within the limitations of this study, canine guidance can be recommended as a comfortable alternative to bilateral balanced occlusion for complete dentures. CLINICAL RELEVANCE This recommendation can reduce the time requirements for the fabrication of complete dentures in dental laboratories.

Abstract
With populations aging around the world, the need for complete dentures is likely to increase in Brazil and other developing countries, as well among low-income populations globally, making the teaching of cost-efficient techniques to dental students essential. The aim of this study was to evaluate the effectiveness of complete dentures fabricated by the simplified method in comparison to the conventional method regarding patients' oral health-related quality of life (OHRQoL) and satisfaction, dentures' functional quality, and masticatory performance of patients who were rehabilitated by dental students. From February 2016 to April 2017, final-year dental students at the Federal University of Alfenas, Brazil, were instructed to fabricate new complete dentures for 36 edentulous patients, who were randomly divided into two groups according to denture manufacturing method: simplified method or conventional method. Patients' OHRQoL and satisfaction and the prostheses quality were evaluated at one, three, and six months. Masticatory performance was evaluated at three months. The results showed there was no significant difference between the two methods regarding OHRQoL, patient satisfaction, prostheses quality, or masticatory performance (p>0.05). All aspects evaluated also remained constant for the same group (simplified method or conventional method) in all periods of evaluation (p>0.05). The study concluded that the simplified method for complete denture fabrication was able to produce protheses with functional quality and patient satisfaction comparable to those produced with the conventional method, even when made by dental students.

Abstract
PURPOSE To evaluate the influence of age, gender, mandibular bone height, previous experience with prostheses, and methods for denture fabrication on masticatory performance of complete denture (CD) wearers. MATERIALS AND METHODS For this study, 29 individuals treated with CDs fabricated by simplified or conventional methods had their masticatory performance assessed 4 weeks after the prostheses' adjustment and control, using the sieve method and almonds as a natural food test. Experimental variables related to age, gender, and previous use of complete dentures were collected from dental records. Panoramic digital radiographs were used to determine mandibular bone height according to the criteria described by the American College of Prosthodontists. Data on masticatory performance were assessed using t-test for independent samples to make comparison between simplified and conventional methods, and a multiple linear regression analysis was performed to evaluate the influence of age, gender, previous experience with CDs, and mandibular bone height on masticatory performance using SPSS software with a significance level of 5%. RESULTS There was no significant influence regarding the method for CD fabrication (p = 0.92), age (p = 0.36), mandibular bone height (p = 0.37), and previous experience with prostheses (p = 0.15) on masticatory performance of CD wearers. Female patients presented lower masticatory performance than male (p = 0.04) patients did. CONCLUSIONS Considering the limitations of this study, it was concluded that gender might be considered a risk factor for masticatory performance of CD wearers. Female patients demonstrated reduced masticatory performance in comparison to male patients.

Denture satisfaction determinants may include denture quality, oral tissue condition, patient-dentist relationship, patient’s attitude toward dentures, patient’s personality and socioeconomic factors. Purpose: The aim of the current review was to identify and analyze the different construction protocols and occlusal schemes that contribute to the success of complete denture rehabilitation through the use of evaluation questionnaires.
Material and Methods: A comprehensive literature search was performed through electronic databases (MEDLINE via PubMed) using the appropriate key words (complete denture construction, complete denture fabrication, complete denture occlusion and complete denture occlusal scheme). The related to the subject scientific papers were selected and evaluated for eligibility utilizing a predefined review process (English, full text articles, published from January 2000 up to April 2017).
Results: None of the analyzed studies identified significant differences between dentures constructed with simplified, CAD/CAM and traditional protocols in terms of general satisfaction and Oral Health Related Quality of Life scales. The same condition applied to the studies which compared complete dentures with bilateral balanced, lingualized, monoplane and canine guided occlusion.
Conclusions: Current scientific evidence suggested that patients could adapt comfortably to any type of bilateral balanced occlusal scheme and to complete dentures been fabricated with all types of complete denture construction protocol. Disease-specific questionnaires could be considered valuable tools and should be used to assess the outcome of any treatment modality.

Abstract
The occlusion of choice is a controversial topic in conventional complete denture (CCD) treatment. This study aimed to compare patient satisfaction with CCD with partially group-function occlusion (PGFO), fully bilateral balanced occlusion (FBBO), buccalised occlusion (BO), lingualised occlusion (LO) and the entire balanced group. Participants received new CCDs with PGFO. All steps of patient enrolment, denture fabrication, assessments during the follow-up period and data collection were carried out exactly the same as part 1 of this research project. All patients were recalled at 1 and 3 months after delivery for data collection using the shortened version of oral health impact profile for edentulous patients (OHIP-EDENT) questionnaire and 7 visual analog scales (VASs) for the quality of CCD based on general patient satisfaction, masticatory function, ability to speak, comfort, stability, retention and aesthetics. Data were analysed using the Wilcoxon signed-rank test, the Kruskal-Wallis test and Mann-Whitney test via SPSS version 18.0 (α = 0.05). Thirty participants completed the follow-up period for PGFO group. The mean age ± standard deviation of the new participants was 57.97 ± 6.93 years. Participants reported significantly less satisfaction in terms of comfort, stability and retention of denture with PGFO compared to balanced groups. Also, using OHIP-EDENT questionnaire, significantly higher physical pain score was noted for PGFO group compared to BO and LO. Higher physical disability score was noted in PGFO compared to LO. Participants receiving CCDs with PGFO reported lower satisfaction in terms of comfort, stability and retention of denture and higher physical pain and physical disability than the balanced occlusal schemes.

Abstract
PURPOSE Tongue activity, involving stereognosis of denture position, food bolus distribution, and direct denture pressing, can affect the stability of removable mandibular dentures. Knowledge of details of tongue activity in patients with removable dentures could contribute to the development of training methods to improve bilateral mastication. The hypothesis of this study was that tongue force improves mandibular complete denture stabilization on the atrophied foundation during mastication load transfer with a typical balanced occlusion. MATERIALS AND METHODS Finite element analysis was used to assess the effect of tongue activity on denture stability, which was evaluated with objective biomechanical criteria. Denture movement (displacement), sliding distance on the mucosal surface, and pressure on the foundation during occlusal load transfer were considered with and without additional tongue forces. RESULTS Tongue force in the canine zone of the balancing flange contributed to a slight reduction in the sliding distance. An adverse effect of tongue force on the working side and in the posterior zone of the balancing side was found. CONCLUSIONS Despite the lack of substantial improvement in stability with the addition of tongue forces, tongue action that contributes to a slight reduction in sliding may help reduce common frictional trauma resulting from cyclic movement during chewing. The beneficial impact of tongue force shown in earlier work under conditions of complete adherence of dentures to the foundation indicates a benefit of using adhesives.

Abstract
PURPOSE To compare the impact of canine guided vs. bilateral balanced occlusion on oral health related quality of life (OHRQoL) as a patient-reported outcome measure. METHODS In this randomized single-blind crossover trial, 19 patients have been provided with new complete dentures in the maxilla and mandible. OHRQoL was assessed using the 49-item Oral Health Impact Profile (OHIP-49) before the start of the prosthodontic treatment (B), 3 months after insertion of the new dentures (T1), and 3 months after rework into the alternative concept (T2). Multilevel mixed-effect linear regression models were computed to determine the effect provided by the new set of dentures and the specific impact of the occlusal concept on OHRQoL using summary scores of the OHIP-49 and of a 19-items subset specific for edentulous patients (OHIP-EDENT). RESULTS At baseline, participants' OHRQoL was substantially impaired indicated by an average OHIP-49 score of 42.1 points and an OHIP-EDENT score of 21.1 points. The effect of provision of a new set of complete dentures was a statistically significant decrease of 8.3 points (OHIP-49) and 4.0 points (OHIP-EDENT), respectively, representing a clinically relevant improvement in OHRQoL. When wearing dentures with bilateral balanced occlusion, participants showed on average 1.6 points higher OHIP-49 scores and 0.9 points higher OHIP-EDENT scores compared to canine guided dentures. This effect of the occlusal concept was neither statistically nor clinically significant. CONCLUSIONS Both investigated occlusal concepts for complete dentures were comparable in their effect on patients' perceptions with none being considerably superior in terms of OHRQoL.

Abstract
The aim of the present study was to assess the effect of a denture adhesive (DA) on patient satisfaction and kinesiographic parameters of complete denture wearers by a cross-over study. Fifty edentulous patients received a set of new complete dentures. After an adaptation period, the participants were enrolled in the trial and randomized to receive a sequence of treatment protocols: Protocol 1- DA use during the first 15 days, followed by no DA for the next 15 days; Protocol 2- no DA during the first 15 days, followed by use of DA for the next 15 days. Outcomes were assessed after 15 days of each sequence of treatment. A questionnaire was used to assess the patients´ satisfaction. A kinesiograph was used to record mandible movements and patterns of maxillary complete denture movement during chewing. The Wilcoxon test (α=0.05) and a paired sample t-test (α=0.05) were used to compare satisfaction levels and kinesiographic data, respectively. Use of DA improved the overall level of patient satisfaction (p<0.001). The kinesiographic recordings revealed a significant increase (1.7 mm) in vertical mandible movements (p<0.001) during chewing and a lower (0.3 mm) vertical intrusion of the maxillary complete dentures (p=0.002) during chewing after using the DA. Use of DA in complete denture wearers improved the patients´ satisfaction and altered mandible movements, with increases in vertical movements during chewing and less intrusion of maxillary complete dentures.

Abstract
For more than a hundred years, it has been supposed that canine guidance should be avoided in conventional complete dentures, since it would result in denture instability. Thus, bilateral balanced articulation has been held by many authors as fundamental for treatment success. However, randomized clinical trials have shown that balanced articulation is not as important as previously thought. The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant for both the dentist and dental technician. Therefore, the purpose of this study is to provide an evidence-based update on complete denture occlusion. Clinical Relevance: The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant.

Abstract
BACKGROUND Orthodontists have several methods to detect inter arch-tooth size discrepancies in patients presenting for orthodontic treatment. Many methods such as Pont's analysis, Nance and Carey's analysis, Peck and Peck ratio, Bolton's analysis are commonly used methods. A thorough search of literature reveals a paucity of reliable data on the mesiodistal dimensions of the crowns of the permanent dentition of Indian population. Without information about the size of individual tooth and groups of teeth for Indian population, it is difficult for the clinician to make an adequate diagnosis and treatment plan and to carry out a plan of therapy. AIM To determine the size of individual permanent tooth and the sex differences, with tooth size ratios according to Bolton's formula and to evaluate the reliability of Bolton's norms (Anterior/ Posterior) in Indian population. MATERIALS AND METHODS One hundred and twenty cases in which an excellent occlusion was naturally existent with the mean age of 22 years (18-27 years) were selected in the study. The casts were prepared after taking alginate impression of maxillary and mandibular arches and pouring them immediately with dental stone. A sliding Digital Vernier calliper used to measure the teeth. The ratios of the mean of mesiodistal dimensions of types of teeth were computed. RESULTS The mean overall ratio for the Indian population is found to be 92.11 with a standard deviation of 2.12. The values ranged from 86.50-97.13 and the median is 92.16. The mean anterior ratio for the Indian population is found to be 78.14 with a standard deviation of 2.59. CONCLUSION Bolton's original data does not represent Indian population. In our study greater size variability was found in maxillary teeth as compared with mandibular teeth except mandibular first molar. Our study indicated that population-specific standards are necessary for clinical assessments. Significant differences were shown for the overall ratio and anterior ratio for both sexes as compared to Bolton's ratio.
