The purpose of this study was to evaluate the clinical outcome of feldspathic ceramic laminate veneers over a 7-year period using minimally invasive techniques, such as vertical preparation (without prosthetic finish line), or no preparation (no-prep). A total of 170 feldspathic ceramic veneers were cemented in the anterior region, including 70 maxillary and 100 mandibular veneers, after special conditioning of the teeth and restorations. The veneers were evaluated using the FDI World Dental Federation criteria evaluation kit after recalling all the patients between February and June 2021. In total, 14 feldspathic veneers failed and were replaced with lithium disilicate because of core fracture, and 10 cases of chipping occurred on the ceramic surface and were polished. The overall survival rate was 91.77% for up to 7 years of function, with a failure rate of 8.23%. In this retrospective survival analysis, the failures, including the fracture of veneers and dental hard tissue, occurred both in prep and no-prep teeth. No failures were observed in veneers with a maximum thickness of 0.5 mm compared to those with a maximum thickness of 1 mm, 1.5 mm, 2 mm, and 2.5 mm.
Nowadays non-carious dental lesions are a frequent pathology that affects teeth by irreversible losing the hard non-carious dental tissues. That can affect patients by damaging the aesthetic and functional aspects. A clinical trial case of adhesive restorations was the approach for patients affected by dental abrasions. All the patients are systematically and exclusively treated with adhesive feldspathic ceramic restorations in the frontal area. In this article, one of full-mouth rehabilitation through adhesive restorations was presented. The tooth structure was not sacrificed; some thin veneers made of feldspathic ceramic was bonded directly on the teeth. At the end of this non-prep therapy was an achieved esthetic and functional outcome for all cases with maintaining the teeth vitality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
