RESUMEN
PURPOSE: To examine the long-term performance of bonded all-ceramic restorations, specifically veneers, in patients with amelogenesis imperfecta (AI). 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.

PURPOSE: This article reports on a retrospective study on patients with a diagnosis of amelogenesis imperfecta and on their prosthodontic management, oral health status, and attitudes toward their condition. MATERIALS AND METHODS: The study comprised 15 patients and consisted of a clinical evaluation and questionnaire. Clinical examination included records of types of restorations and cements used, rating of restoration quality, as well as complications and periodontal variables. RESULTS: The 15 patients had a total of 213 prosthetic restorations. The median age of the restorations was 60 months. Following the California Dental Association's system, all restorations were rated as acceptable to excellent, with one exception. During the follow-up period, four (2%) restorations had been recemented and 16 (8%) restorations had been redone, five (2%) because of porcelain fractures and 11 (5%) because of caries; two (1%) endodontic treatments were performed after prosthetic restoration. Plaque and Bleeding Indices were 28% and 21%, respectively, while pocket depths of more than 3 mm were found at 7% of all tooth surfaces. All patients judged their condition as having affected them negatively. However, after prosthodontic rehabilitation, patients experienced an improvement in self-esteem. CONCLUSION: Patients with severe clinical manifestations of amelogenesis imperfecta obtained extensive prosthodontic treatment at an early age. The restorations had in general performed well, and all patients were affected positively as a result.
