ABSTRACT:
An oral implant for supporting an artificial tooth structure has an implant portion adapted to be fitted in an opening in a bone in the vicinity of the occlusal plane of a patient in such a manner that at least a part of the connection part extends beyond a rim of the opening in the bone or can remain just below the bone while the base of the post rests on the bone. There is at least one post portion having first and second ends. The first end is adapted to receive at least a part of the artificial tooth structure. The second end is adapted for a direct connection to the connection part of the implant portion. The past may be connected to the implant portion by an arrangement in which the implant portion has an opening along the upper surface. Ridges are provided along the sides of the opening and a center projection extends up from the base of the opening. The post portion has complementary channels and openings for receiving the ridges and projection.
