| abstract |
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 having an upper surface for supporting an aesthetic veneer and a lower surface having a recess therein, the cast member having a fastener support located above the recess and comprising a flange and a retaining wall projecting out from an upper edge of the flange. A sleeve is supported on the abutment between the abutment and the recess in the lower surface, and a preferably flathead fastener is supported in the retaining wall for securing the cast member to the abutment. A cement composition is provided in the recess in the lower surface to insure accurate adaptation of the cast member to the abutment upon installation. |
