A new design for all-ceramic resin-bonded fixed partial dentures

After 7 years of clinical experience, the alumina ceramic, In-Ceram, can be regarded as a well-proven material for all-ce ramic crowns. Because of its high strength, this material can also be used for small all-ceramic fixed partial dentures. First attempts at using this material for resin-bonded prostheses revealed a high failure rate. The aim of this article is to present a new preparation design for all-ceramic resin-bonded fixed partial dentures that allows fabrication of highly esthetic and also tooth-saving adhesive prostheses. Clinicial results over a per iod of 4 years revealed that they are strong enough to replace anterior teeth. Nevertheless, positive long-term clinical results are necessary before a general recommendation can be given for this kind of prosthesis.
