Abstract
Abstract This invention relates to a prosthetic dental tooth implant for anchoring a tooth to the jaw bone of an individual. The device is a blade like section having a number of circular holes having a slot-like aperture in a bottom portion of the blade to provide flexure of the blade and outwardly bendable prong extending from a top portion of each hole for anchoring engagement against an inner surface of the cortical plates adjacent the aveolar tissue of the jaw bone.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
A tooth implant for anchoring a tooth or tooth-like prosthesis to the jaw bone of an individual, comprising: a blade-like section for implantation within soft aveolar jaw bone tissue, said blade-like section having a number of substantially circular holes having a slot-like aperture in a bottom portion of said blade to provide for flexure of the blade and outwardly bendable prongs extending from a top portion of each of said holes for anchoring engagement against an inner surface of the cortical plates adjacent said aveolar tissue of said jaw bone, said prongs designed to support said blade-like section experiencing downwardly directed masticatory forces, and at least one stem section extending from said blade-like section and designed to receive a tooth or tooth-like prosthesis.
Claim 2
Dependent Claim
123 words
A tooth implant for anchoring a tooth or tooth-like prosthesis to the jaw bone of an individual, comprising: a blade-like section for implantation within soft aveolar jaw bone tissue, said blade-like section having a number of substantially circular holes having a slot-like aperture in a bottom portion of said blade to provide for flexure of the blade and outwardly bendable prongs extending from a top portion of each of said holes for anchoring engagement against an inner surface of the cortical plates adjacent said aveolar tissue of said jaw bone, said prongs designed to support said blade-like section experiencing downwardly directed masticatory forces, and at least one stem section extending from said blade-like section and designed to receive a tooth or tooth-like prosthesis.
Claim 3
Dependent Claim
41 words
The tooth implant of claim 1, wherein said blade-like section has at least two prongs, one of said two prongs for engagement against a lingual cortical plate and the other of said two prongs for engagement against a buccal cortical plate.
Claim 4
Dependent Claim
28 words
The tooth implant of claim 1, wherein said stem section has a slot in an end portion thereof, for receiving a bar member of an artificial tooth assembly.
Claim 5
Dependent Claim
26 words
The tooth implant of claim 1, wherein said stem section has an aperture therein for receiving a pin fastener for securing said tooth or tooth-like prosthesis.
Claim 6
Dependent Claim
14 words
The tooth implant of claim 1, wherein said stem section has a truncated shape.
Claim 7
Dependent Claim
