Abstract
Abstract A dental implant assembly consists of one or more planar members adapted to be introduced into complementary cavities or slots formed in the jaw bone. Threaded fasteners are disposed through holes in the jaw bone and oriented in directions generally normal to the planar members. Threaded apertures are provided in the planar members which are engageable with the threaded fasteners for immobilizing the planar members within the cavities relative to the jaw bone. At least one of the fasteners includes a support portion which projects exteriorly of the jaw bone when the planar members and the fasteners are in engagement. The support portion is adapted to support a dental prosthetic device in fixed relation to the jaw bone during engagement. A dental jig for accurately drilling the holes in a jaw bone which receive the fasteners is described. The method of inserting a planar dental implant assembly member into a jaw bone includes cutting in the jaw bone a slot complementary to the planar member and drilling holes in the jaw bone between the alveolar crest and the slot under the guidance of the apertures in the jig. The planar member is inserted into the complementary slot and screws are introduced through the holes drilled in the jaw bone and engage threaded apertures provided in the planar member. At least one exposed portion associated with the threaded screws is retained exposed which is adapted to support a prosthetic device. A jig is also described for forming two slots essentially aligned in a common plane and disposed in opposite lingual sides of the jaw bone.
