[The ceramic system In-Ceram in the prosthetic dentistry--clinical and experimental results].

The ceramic system In-Ceram is a metal-free method to manufacture ceramic crowns and bridges. The metal framework is replaced by a sintered, glass infiltrated aluminium oxide substructure of high strength. Due to improved material properties the implementation of ceramic dental restorations allows a wider range of application. The paper presents own clinical experiences as well as recommendations concerning the dimensions of the aluminium oxide substructure.
