ABSTRACT:
A method and apparatus for connecting an artificial tooth portion to a dentin portion utilizing an elongated member having a generally circular cross sectional shape on one end portion thereof and barbs, each having a base portion and a free end attached to and disposed around the periphery of the one end portion thereof for directly engaging the dentin portion within the bore. The barbs are oriented such that the free end is spaced around the periphery in one direction from the base portion. The method includes the steps of removing a portion of a tooth down to the dentin portion, forming an opening having interior walls in the dentin portion of the tooth which is slightly larger in diameter than the diameter of the circular cross sectional one end portion of the elongated member, forcing the one end portion of the elongated member into the opening while simultaneously rotating the elongated member, whereby the barbs are tightly wedged against the interior walls thereof and whereby the other end of the elongated member extends out of the opening; and, attaching the artificial tooth portion to the other end of the elongated member and in abutment with the dentin portion of the tooth whereby the artificial tooth portion is held in place with respect to the tooth.
