Patients received two questionnaires: (1) a modified version of a condition-specific questionnaire- the Cleft Research Questionnaire (CRQ), used to investigate demographic, life, and treatment details and impacts-and (2) the Oral Health Impact Profile (OHIP-14), used to investigate the oral health-related quality of life. Patients were assigned to three presentations (Types 1 to 3) of oligodontia, identified according to the edentulous space present and complexity of prosthodontic treatment required. The hypothesis that there is a relationship between oligodontia type and study variables was tested.Results: Twenty-two questionnaires were completed and returned. There were 13 men and 9 women. The age range was from 16 to 32 years. In total, 18 patients had nonsyndromic oligodontia and 4 had oligodontia associated with anhidrotic ectodermal dysplasia (AED). The main areas of impact were patient-reported: life less satisfying (64.5%, n = 14; pretreatment), making friends (45%, n = 10), school participation (45%, n = 10), and public speaking (45%, n = 10). No relationship was discovered between the degree of physical effect of the presentation type and study variables, including the degree of psychosocial impact or life satisfaction.Conclusions: Oligodontia can have a negative functional and social impact on a patient prior to prosthodontic treatment. Prosthodontic treatment improved the life satisfaction for most patients. Psychosocial outcomes could not be inferred by the presentation type of oligodontia.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"518-525"},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138292678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The School of Articulator Munich (SAM) Axioquick system was used to assess the condylar guidance and eccentric tracings of the patients. For analyses, Student t test was used. For quantitative data, the means and SDs were calculated. For statistical analyses, the probability of type-I error of .05 was considered statistically significant.Results: The mean condylar guidance for canine-guided and group function occlusion was 38.4 ± 12.7 degrees and 30.5 ± 12.5 degrees on the right side, respectively. On the left side it was 36.5 ± 13.0 degrees and 27.5 ± 12.0 degrees for canine-guided and group function occlusion, respectively, with a statistically significant difference (P = .01). The condylar guidance, incisal guidance, Bennett angle, protrusion, left lateral and right lateral movement, and left and right lateral angles were analyzed statistically between the two types of occlusions. The results showed a statistically significant difference between the two groups for all parameters except right condylar guidance. Furthermore, all parameters were higher in the canine-guided occlusion group over group function occlusion.Conclusions: Within the study limitations, it was concluded that the condylar guidance was steeper in canine-guided occlusion than in group function occlusion. The eccentric parameters were steeper in canine-guided occlusion than in group function occlusion. This study showcases that the condylar guidance might not play a major role in determining the occlusal scheme but that the incisal guidance determines the occlusal scheme predominantly in Class 1 occlusion patients.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"505-511"},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41224429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were divided into a subgroup (brachyfacial, mesofacial, and dolichofacial facial forms) using facial index measurement and cephalometric analysis. After the subjects were divided into groups, masticatory efficiency testing was performed with spectrophotometric analysis using diluted expectorate of chewed natural beetroot test food (10, 15, and 20 strokes).

The study protocol was approved and was registered in the International Prospective Register of Systematic Reviews (PROSPERO: CRD42021268449).

There are few studies of long-term outcomes using a minimally invasive procedure in these patients. This aspect is essential when treating young patients. All-ceramic restorations, especially veneers, offer a more tissue-preserving treatment but rely on successful bonding. However, due to the defect enamel in AI patients, the bond strength is lower.Materials and methods: A retrospective evaluation of 40 subjects with AI (26 women, 14 men) was provided with a total of 360 bonded restorations (282 veneers, 78 crowns). The restorations were evaluated according to complications, survival, and success rate.Results: The patients were observed up to 25.3 years (mean 15.4 ± 4.3 years). The mean age when receiving the restorations was 18.5 ± 4.2 years. In total, 59 (16.4%) restorations with prosthetic complications were made, 29 of which (8.1%) were remade (6 due to esthetic reasons, all in one patient) and 30 (8.3%) were recemented (60% caused by trauma). We found 11 teeth with caries and 3 with endodontic complications. The overall survival rate was 91.9%, and the overall success rate was 83.6%.Conclusions: Bonded all-ceramic restorations with no active retention in AI patients have excellent performance. The most common complications were debonding and fractures. The treatment should be based on individual indications and be preceded by a multidisciplinary approach.","PeriodicalId":94232,"journal":{"name":"The International journal of prosthodontics","volume":"0 0","pages":"404-410"},"PeriodicalIF":0.0,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139975216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
