ABSTRACT
Abstract The aim of this study was to understand the influence of orthosurgical treatment on oral health-related quality of life (OHRQoL) in patients with Class II and III skeletal malocclusion by conducting a mixed method case series study. Nineteen patients submitted to orthosurgical treatment in a private practice in Brazil were included in the sample. Data were collected retrospectively and interviews were held from March 2020 to July 2021. Patients answered to the Oral Health Impact Profile (OHIP-14) in the first part of the interview and subsequently answered the qualitative questions. The overall mean of OHIP-14 after treatment was 4.21 (SD 4.68). The qualitative data were analyzed according to thematic analysis and four themes emerged from the interviews: a) concept of quality of life, b) pre-treatment life, c) post-treatment life, and d) positive and negative aspects of treatment. Quality of Life was reported by the patients as the absence of feeling pain, having emotional and physical health, having a satisfactory esthetic appearance and self-esteem. Before treatment, most Class II patients used to complain about breathing and sleeping problems, while Class III patients complained more intensely about esthetics. Pain was a common problem reported by both Class II and Class III patients. In general, improvement was perceived in self-esteem, esthetics, function and pain. Complaints about negative aspects of the treatment were restricted to the postoperative period. The orthosurgical treatment was important for improving the OHRQoL of patients in terms of esthetic, functional and psychosocial aspects.
ABSTRACT
O objetivo do presente estudo foi revisar a literatura dos últimos cinco anos e identificar os índices de sobrevivência, principais causas de falha relatadas e verificar a confiabilidade dos laminados cerâmicos como tratamento estético e funcional em longo prazo. Métodos: foi realizada uma busca ativa na Biblioteca Nacional de Medicina dos Estados Unidos (pubmed.ncbi.nlm.nih.gov), através da base de dados Medline, dos últimos cinco anos (2015-2020) na língua inglesa, utilizando os descritores: Laminate Veneers, Porcelain Laminate Veneers e Ceramic Laminate Veneers, que resultou em 35 artigos. Após a leitura dos resumos, foram excluídos 9 estudos que utilizaram laminados cerâmicos não produzidos em cerâmicas feldspáticas, ou vidro ceramizados reforçados por cristais de leucita, ou dissilicato de lítio. Foram selecionados 26 artigos categorizados como: relatos de caso, estudos clínicos, estudos in vitro e revisões de literatura. Resultados: os estudos apontaram índices de sobrevivência de 100%, após 2 anos de cimentação, até valores superiores a 80%, após 14 anos. As três principais causas de falhas apontadas foram: desadaptação de marginal (37%), pigmentação das margens (30%) e fratura ou lascamento das restaurações (3%). Considerações finais: dentro das limitações do estudo, foi possível concluir que as principais causas de falha estão associadas às margens da restauração, no entanto, os laminados cerâmicos podem atingir índices elevados de sobrevivência mesmo 14 anos após a cimentação, mostrando um alto nível de confiabilidade.

The objective of the present study was to identify the survival rate and cause of failure of ceramic laminate veneers. Methods: An active search of the last five years (2015 2020) was carried out in the United States National Library of Medicine (pubmed.ncbi.nih.gov) the MEDLINE database, in English, using the descriptors: Laminate Veneers, Porcelain Laminate Veneers and Ceramic Laminate Veneers, which resulted in 35 papers. After reading the abstracts, 9 studies that evaluated ceramic laminates that were not produced using felspathic porcelain, leucite-reinforced glass-ceramicc, or lithium disilicate glass-ceramic were excluded. Twenty-six scientific papers were selected, categorized as: Case reports, clinical studies, in vitro studies and literature reviews. Result: The studies showed survival rates between 100% after two years of cementation up to values above 80% after 14 years. The three causes of failure identified were: marginal misfit (37%), pigmentation of the margins (30%), and fracture or chipping of the restorations (3%). Final Considerations: Within the limitations of this study, it was possible to conclude that the leading causes of failure are associated with the restoration's margins. However, ceramic laminates can achieve high survival rates even 14 years after cementation, showing a high-reliability level.(AU)
