Survival rate of porcelain veneers versus indirect composite resin veneers in patients with bruxism: a systematic review

Abstract

Finding the best aesthetically pleasing and durable material for anterior restorations is the subject of increasing numbers of studies. The material of preference may also be influenced by factors like bruxism or tooth preparation. The aim of this systematic review was to compare the clinical outcomes of indirect composite laminate veneers and porcelain veneers in bruxism patients. Material and Methods: An electronic search was performed in the PubMed, Scopus, and Web Of Science databases on porcelain veneers and indirect composite resin veneers in patients with bruxism until January 2023. Results: Of 433 potentially eligible papers, 11 complied with the inclusion criteria: 8 articles described characteristics and survival rate of porcelain veneers, 2 made a comparison of survival rate of both porcelain veneers and indirect composite resin veneers and 1 illustrated the digital CAD CAM method. It can be noted that the indirect composite resin (Estenia) veneers have a general lower survival expectancy: 87% after 20,3 months and 75% after 97 months. Regarding the survival rates of ceramic veneers: IPS-Empress ceramic 100% after 20,3 and 97 months and 89,5% after 11 years. Feldspathic ceramic reinforced with leucite crystals 95% after 11 years. Feldspathic ceramic 89,1% using an occlusal splint and 63,9% using no occlusal splint after 7 years. Ceramic veneers have compared to indirect composite better properties as veneer materials. Fractures of the veneers are less frequent in patients who use an occlusal splint adequately.
