Abstract:

With the increasing demand for oral esthetics, porcelain restoration has become the main trend of fixed dental prostheses. However, the mechanical strength of all-ceramic restorations composed of core porcelain and veneering porcelain is one of the concerns about clinical applications. Therefore, we should determine the effective designs of all-ceramic restorations to bear the complicated occlusal force of the oral cavity. However, the influence of the thickness of core porcelain and veneering porcelain on the flexural strength of full-ceramic restorations remains unclear. Comprehensive investigations have focused on the mechanical properties of full-ceramic restorations. Various experimental designs, backgrounds, and methods have been developed. This paper reviews previous studies and analyzes their differences.

Key words: core porcelain, veneering porcelain, thickness, flexural strength
