Abstract
Aim and objectives The aim of this study is evaluation of metal-ceramic prostheses interface. The metallic frameworks were made with two technologies. Material and methods For samples manufacturing, was used the NeWay Open Technology Scanner. On the virtual cast, was designed the metallic framework with EXOCAD program for SLS. The patterns for the melting-pouring technology were milled in wax using the Zenotec Select Hybrid. The veneering of Co-Cr metallic frameworks was made with IPS d-SIGN (Ivoclar Vivadent) ceramic. The samples were cut and investigated with the optical microscope. Results Optical Microscopy revealed inclusions and dehiscence on metal-ceramic interface of pour-melted frameworks. The interface of ceramic and sintered framework had dehiscence and the veneering ceramic showed spherical inclusions. Conclusions The errors of detaching the veneered ceramic are reduced in case of SLS due to the adherence of ceramic which is higher for SLS metallic infrastructures.
