<p>The present invention relates to a framework for a fixed/detachable prosthesis that is assembled intraorally onto at least one abutment supported by an osseointegrated implant. The framework comprises a cast member (70) having an upper surface (72) for supporting an aesthetic veneer and a lower surface (74) having a recess therein, the cast member having a fastener support (78) located above the recess and comprising a flange (80) and a retaining wall (86) projecting out from an upper edge of the flange. A sleeve (92) is supported on the abutment between the abutment and the recess in the lower surface, and a preferably flathead fastener (90) is supported in the retaining wall for securing the cast member to the abutment. A cement composition (93) is provided in the recess in the lower surface to insure accurate adaptation of the cast member to the abutment upon installation.</p> |
