Abstract

The purpose of this research is to evaluate the clinical performance of lithium disilicate manufactured by CAD/CAM tecnology, comparing with those venneers produced by the pressed technical of press pellets (IPS e.max Press), in a period of 6, 12 and 24 month evaluation. 80 patients will be selected with veneers need for anterior teeth, with a minimum of two and a maximum of six venners per patient. The sample will be randomized into two groups: (1) e.max CAD - Images obtained with inEos Blue scanner, followed by milling IPS e.max CAD blocks (Ivoclar, Liechtenstein) for CEREC inLab (Sirona) and (2) e.max Press - Manufacturing of lithium disilicate ceramic veneers (IPS e.max Press -Ivoclar, Liechtenstein) with the use of press pellets, following the standards and the manufacturer's instructions. The veneers will be scored according to criteria of USPHS (United States Public Health Service): marginal adaptation, color change, marginal discoloration, restoration fracture, tooth fracture, wear restoration, antagonist wear, presence of caries and postoperative sensitivity. Success rates and survival rates will be estimated based on Kaplan-Meier analysis considering a 95% confidence interval. (AU)
