[Marginal behavior of "Kulzer" composite inlays under simultaneous mechanical and thermal loading].

Abstract

This in vitro study assessed the marginal behavior of the "Kulzer"-inlay using two different resin luting agents (Adhesive cement resp. Tulux-Cem). SEM-evaluation after combined mechanical and thermal loading revealed significant differences in the marginal seal of the inlays depending on the luting composite resin used. "Kulzer"-inlays luted with Adhesive cement showed of rate a excellent margins of more than 90% even after in vitro load application, while the rate of perfect margins were less than 80% for "Kulzer"-inlays inserted with Tulux-Cem.
