Longevidad y desempeño clínico de las carillas cerámicas : una revisión sistemática.

Abstract

Background: ceramic veneers are increasingly used as an alternative for restorative treatment in dental practice, therefore it is important to know what factors influence its longevity and clinical success. Objective: to determine the factors that affect the clinical performance and longevity of cemented ceramic veneers. Materials and methods: a systematic, qualitative, cross-sectional, descriptive and analytical design review was carried out; through metasearch engines such as PubMed and Cochrane. 34 articles were selected considering the variables: longevity; clinical performance; bruxism; incisal preparation design; adhesion to different dental structures; type of cement used and choice of veneer fabrication material. Analysis and discussion: the survival rates of the veneers were: in the presence of bruxism with the use of a splint 98.9%, and without the use of a splint 91.4%. In preparations with incisal coverage 96% and without coverage 85.5%. Lithium disilicate veneers 94% and feldspathic porcelain veneers 87%. Failure rates were: in cemented veneers limited to enamel 1.3% and in cemented veneers to exposed dentin 31.9%. Dual-cure cement experienced greater discoloration than light-curing cement. Conclusions: to obtain the greatest longevity and clinical success of ceramic veneers, the use of a splint is indicated in bruxist patients; choose preparations limited to enamel and with incisal cover designs, select light-curing cements, and glass-ceramics as a manufacturing material.
