DISCREPANCIA MARGINAL DE COFIAS EN ZIRCONIO ELABORADAS CON DOS SISTEMAS CAD/CAM

Purpose: To compare the marginal discrepancy of copings made in zirconium oxide with two systems CAD/CAM.Methods: In vitro marginal discrepancies of two systems CAD/CAM (Procera® and Everest®) for ceramic copings and a control group of gold copings were evaluated and compared.

A first one human premolar superior was prepared, duplicate 30 times and divided in three groups. Ten copings by group were made. The measurements of marginal discrepancy were made on the natural tooth, on 20 points distributed randomly around the margin preparation. A 3D microscope video was used with magnification of 200X. Values of average and standard deviation were calculated for the marginal openings. The data were analyzed with analysis of variance of a route ANOVA.Results: mean of the marginal discrepancies and standard deviations of the copings were 29±8.6 um for the control group, 22,31±14.6um for Everest® and 21.55±6.9um for Procera®. Significant differences were not found between the copings of the three groups (P> 0.05).Conclusions: The marginal discrepancies were all within the clinically acceptable standard set at 50-100mm, However, Procera® and Everest® systems showed the smallest marginal discrepancies compared with the copings made in an alloy of medium gold content.Objetivo: Comparar la discrepancia marginal de cofias elaboradas en óxido de zirconio con dos sistemas CAD/CAM. Materiales y métodos: Discrepancias marginales in vitro de dos sistemas CAD/CAM (Procera® y Everest®) para cofias cerámicas y un grupo control de cofias en oro fueron evaluadas y comparadas. Un primer premolar superior humano fue preparado, duplicado 30 veces y dividido en 3 grupos. Diez cofias por grupo fueron fabricadas. Las mediciones de discrepancia marginal fueron realizadas sobre el diente natural, sobre 20 puntos distribuidos aleatoriamente alrededor del margen preparado. Se utilizó un video microscopio 3D con magnificación de 200X. Valores de media y desviación estándar fueron calculados para las aperturas marginales. Los datos fueron analizados con análisis de varianza de una vía ANOVA. Resultados: Los promedios de las discrepancias marginales y desviaciones estándar de las cofias fueron 29 ±8.6 micras para el grupo control, 22.31 ±14.6 micras para el Everest® y 21.55 ±6.9 micras para Procera®. No fueron encontradas diferencias significativas entre las cofias de los tres grupos (P >0.05). Conclusiones: Las discrepancias marginales obtenidas se encuentran dentro de los rangos clínicamente aceptables entre 50-100 micras; sin embargo, Procera® y Everest® presentaron menores discrepancias marginales comparadas con las cofias elaboradas en una aleación de mediano contenido de oro.[Pinilla SM, Barrera GC, Palomino EE, Quijano MA, Henao D.
