Dental prostheses mimic the natural enamel behavior under functional loading: A review article

Publication date: Available online 1 September 2015 Source:Japanese Dental Science Review Author(s): Ahmed A. Madfa, Xiao-Guang Yue Alumina- and zirconia-based ceramic dental restorations are designed to repair functionality as well as esthetics of the failed teeth. However, these materials exhibited several performance deficiencies such as fracture, poor esthetic properties of ceramic cores (particularly zirconia cores), and difficulty in accomplishing a strong ceramic–resin-based cement bond. Therefore, improving the mechanical properties of these ceramic materials is of great interest in a wide range of disciplines. Consequently, spatial gradients in surface composition and structure can improve the mechanical integrity of ceramic dental restorations. Thus, this article reviews th…
