Abstract: Apparatus and method for fastening a denture plate with many artificial teeth to a plurality of implants screwed into the bone is disclosed that may be completed on the same day as surgical implantation of the implants. The denture plate is prepared before surgery. A rigid metal bar is prepared that is fitted to register with the implants after the implants have been implanted. The rigid metal bar is affixed to the denture plate. Screws through the bar are received into the top of each implant to thereby secure the bar and the attached denture plate to the implants. This distributes the tooth forces among the implants for enhanced function. The bar is composed of a metal attachment for each implant. A pair of wings extends out from each attachment. The attachments are temporarily mounted on the implants so that wings from adjacent attachments overlap. The attachments and wings are temporarily joined with cement. The cemented bar is mounted on a support, the cement removed, and the bar fastened together permanently. The bar is then attached to the denture and the combination mounted on the implants.
