Method, apparatus and device for dental prosthesis implantation
First Claim
1. A method for installation in the jaw bone of a patient of a dental prosthesis including an implant, comprising the steps:
- (a) providing an opening in the gum at the intended site of implantation;
(b) forming a socket to receive said implant in the jaw bone at the opened site;
(c) inserting said implant in said socket;
(d) positioning at least one support plate on at least one of a buccal side and lingual side of said jaw bone;
(e) passing at least one screw through said at least one support plate, said at least one support plate being retained against said jaw bone by said screw, and at least partially through said jaw bone and implant, said screw holding said implant in said jaw bone socket.

Abstract
A dental implant, placed into a socket formed in the jaw bone, is held in position by screws that pass through the jaw bone from the buccal cortical surface to the lingual cortical surface, and through the implant that is located between the cortical surfaces. Threads on the screw shank form and engage threads in the cortex on opposite sides of the jaw bone. The implant, when inserted in the socket and anchored by the screws, is immediately strongly held to the jaw'"'"'s bony structure. Stresses applied to a prosthetic device, e.g., a tooth crown that is attached to the implant, are substantially borne by the cortex by way of the screws.

12. A dental prosthesis, comprising:
-
an implant for insertion in a first direction into a socket formed in a jaw bone where a natural tooth is absent, said implant having an axis oriented in said first direction, engagement means at one end for joining to a prosthetic tooth element, and at least one screw hole through said implant in a second direction transverse to said first direction at a location to be within said jaw bone after implantation; at least one surgical screw having a diameter for passing through said at least one screw hole, said screw having a fit in said screw hole to limit motion therebetween; and at least one support plate for positioning against at least one cortical surface of said jaw bone, said at least one screw, in use, passing through said at least one plate and through said at least one screw hole in said implant to hold said at least one plate against said jaw bone in fixed relationship to said implant. - View Dependent Claims (13, 14, 15, 16, 17)

18. A dental prosthesis comprising:
-
an implant for insertion in a first direction into a socket formed in a jaw bone where a natural tooth is absent, said implant having an axis oriented in said first direction, engagement means at one end for joining to a prosthetic tooth element, and at least one screw hole through said implant in a second direction transverse to said first direction at a location to be within said jaw bone after implantation; at least one surgical screw having a diameter for passing through said at least one screw hole, said screw having a fit in said screw hole to limit motion therebetween, said at least one screw having a length to extend through the jaw bone from a buccal side to a lingual side, and having a lead end and a screw head end and being threaded at its lead end and adjacent said screw head end so as to threadably engage said buccal and lingual sides of said jaw bone, said threads at said lead end have a smaller diameter than said threads at said screw head end. - View Dependent Claims (19, 20, 21)

26. A dental prosthesis, comprising:
-
an implant for insertion in a first direction into a socket formed in a jaw bone where a natural tooth is absent, said implant having an axis oriented in said first direction, engagement means at one end for joining to a prosthetic tooth element, and at least one hole through said implant in a second direction transverse to said first direction at a location to be within said jaw bone after implantation; at least one fastening means having a cross section for passing through said at least one hole, said fastening means having a fit in said hole for limiting motion therebetween and for holding said implant in said jaw bone; and at least one support plate for positioning against at least one cortical surface of said jaw bone, said at least one fastening means, in use, passing through said at least one support plate and through said at least one hole in said implant to hold said at least one support plate against said jaw bone in fixed relationship to said implant. - View Dependent Claims (28)
