An implant system may comprise implants, abutments, cylinders and a structural framework with a veneer thereon. A prosthesis comprises the structural framework and veneer. The cylinders are provided with grooves or shelves thereon to retain a structural framework thereon. The structural framework may comprise fiber reinforced composite material which is disposed on and around the cylinders to provide the framework for a prosthesis. Abutments are provided for single or small implant systems wherein the abutments comprise mechanical retentive features such as grooves, holes, nodules or beads thereon for retaining polymeric material thereon. |
