Rationale for a fixed implant-supported transitional prosthesis in full-arch implant restorations

The use of a fixed transitional prosthesis in implantology remains quite seldom, although the concept of temporization and progressive loading of prosthetic restorations has become a main issue in modem dentistry. Fixed tansitional prostheses play an important role in the validation of full-arch implant-supported restorations, and in the success of implant treatments in general. This paper reviews the basic treatment principles, and discusses the different technical options available to the clinician. In simple cases, a hard resin bridge may be sufficient. However, for complex cases, we should better use fixed implant-supported temporary prosthesis, made in resin on a metallic infrastructure. Moreover, this one could be use as the framework of the permanent prosthesis. This technical solution offers the best guaranty for implant and oral rehabilitation validation before the permanent prosthesis installation. (C) 2007 Elsevier Masson SAS. All rights reserved.
