Evaluación del valor entre los cementos resinosos y pastas prueba en carillas cerámicas. Clínica UCSG semestre A-2019.

Abstract

NTRODUCTION: Dental veneers are one of the most popular treatments for the restoration of nonaesthetic anterior teeth. It is generally used to close diastema, restoring morphological and structural defects, and improving the appearance of slightly discolored teeth. This treatment has many advantages such as an excellent biocompatibility, natural appearance and an excellent clinical success rate. The test pastes simulate the color of the resin or cement. Resin cements are adhesive of choice for veneers. These, like their test pastes, come in several shades, give the possibility of selecting a shade to give the final value of the restoration. They must be able to absorb the compression forces and reduce the loads on the veneer, in order to achieve stability, longevity, harmony and a satisfactory clinical result. OBJECTIVE: This study aims to evaluate the value between resinous cements and their try in pastes in ceramic veneers. MATERIALS AND METHODS: Observational cross-sectional descriptive study, in which 23 patients were evaluated, with a total of 52 ceramic veneers on anterior teeth, at the UCSG clinic semester A-2019, intraoral photographs were taken to assess the value using resin cements with their respective try in pastes, using the Adobe Camera Raw program that comes with Photoshop and Photoshop Elements. RESULTS: Regarding the incidence of gender, it was 65% female, and 35% male. Regarding the tonality of the resin curing cements with the All Cem FGM and Variolink N brands from Ivoclar Vivadent, 50% translucent, 23% A2, and 8% light and 27% warm. As for the luminosity of the veneers evaluated, the luminosity of the veneers already cemented with resinous cement of curing obtained a value of 63.08; which was found in a neutral value. As for the value relationship between the cement of the resinous cements and their test pastes, the FGM All Cem translucent resinous cement, the luminosity value obtained was 64.88. With its try in increases to a value of 65.85. With resin cement with AllCem A2 shade of FGM, the brightness value was 62.25. With its test paste, it increases to a value of 63.75. With the resinous cement with a light hue, from Variolink N from Ivoclar Vivadent, the brightness value was 56.25; With its test paste, it increases to a value of 60.75. The resin cement with warm hue, from Variolink N from Ivoclar Vivadent, the luminosity value obtained was 61, with test paste increases to a value of 62.21. In 31 cemented veneers the value of the resin resin already cured was lower than the test paste, in 17 veneers the value of the resinous cement was greater than the test paste and in 4 veneers the value of the resin cement and its test paste is the same. CONCLUSION: There is a difference in the brightness value between the test paste and its resin curing cement. This difference in value is minimal, which does not produce clinically significant changes in the final restoration. Pastes are a reliable method, which simulates the color of the resin or cement with which it will be cemented, and thus better stability, longevity, and harmony can be obtained.
