Abstract
A prosthetic abutment made from metal for securing to the enossal part of a dental implant is capable of being adapted to the natural shape of the individual teeth inasmuch as it ends on the occlusal side in a truncated cone produced by removal of material from a paraboloid of revolution, said truncated cone having in cross-section a semi-elliptical base plane on the labial side and a paraboloid base plane on the lingual side.
