An implant-supported, cobalt-chromium milled bar and nonflanged attachment-retained overdenture to rehabilitate the edentulous mandible.
Rehabilitation of the edentulous mandible has been revolutionized by the use of osseointegrated endosteal implants. One treatment option for such rehabilitation is an implant-supported bar and overdenture. This article presents a procedure for the fabrication of an implant-supported, cobalt-chromium milled bar and nonflanged attachment-retained overdenture. The prosthesis described meets requirements for masticatory efficiency, natural esthetics, and maintenance of the health of residual tissues. The biological and mechanical considerations of the design, and the advantages, disadvantages, and contraindications of the prosthesis are discussed. (J Prosthet Dent 2009;102:46-51).
