Estudio comparativo in vitro de la adaptación marginal e interna de coronas cerámicas en feldespato elaboradas con técnica de impresión digital y convencional

Abstract

This paper shows the comparison of two digital printing techniques digital and convetional, using the optical scanner (InEos X5) Sirona CEREC with the In Lab 4.2 software and the intraoral direct capture chamber (Omnicam), Materials and Methods A premolar die was made with preparation for free metal crown (feldspar vita Mark II) in steel, which was the standard model to create forms and then perform the 60 castings in epoxy resin, which were divided into two groups; group A consisted of 20 dies and were scanned with the (InEos X5) sirona CEREC and subsequent cementation of the crowns in feldspar and group B consisted of 20 dies and were scanned with the intraoral direct capture chamber (Omnicam) and subsequent cementation of the crowns in feldspar, at 40 crowns transverse cuts were made with the objective of buying the marginal and internal adaptation of the individual crowns in Feldespato made with two digital printing techniques. Using the Mann Whitney U test the results showed that when comparing the two techniques of digital printing it is evident that there are no statistically significant differences between the adaptation of individual crowns in feldspar with conventional printing and printing with Omnicam.
