<p>A temporary dental prosthesis (60) which can be placed before, after or simultaneously with the placement of permanent implants is securely and accurately fixed to mounting assemblies (58). Each mounting assembly (58) has a combination implant/abutment member (10) screwed into a bore formed in the cortical bone with a smooth convex basal portion (12) received in a complimentary shaped recess formed at the entrance of the bore. A coping (30) is received on the head (16) of the combined implant/abutment member (10) and retained there by a pin (50) having a threaded portion (56) received in a threaded bore (24). The copings (30) and pins (50) are received in oversized bores formed in a blank temporary prosthesis and resin is injected around the copings and pins to secure the copings to the prosthesis at locations corresponding to the positions of the combined implant/abutment members (10).</p> |
