Abstract
Abstract An endosseal implant for the support of an artificial tooth consists of a U-shaped surgical metal wire having a flattened and sharpened bight portion adapted to be hammered into the spongy bone structure forming the alveolar crest. The wire arms of the implant protruding into the oral cavity are shortened, if necessary, and form into occlusion with the opposing teeth and an artificial tooth or teeth are attached to the arms by conventional techniques.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
An endosseal implant for dental prosthesis which requires no incising and pre-drilling of the gum tissue and jaw bone comprising a unitary surgical round metal wire section having a diameter of about one millimeter including a pair of bendable and trimable substantially parallel and substantially equal length segments, and a flattened chisel-like transverse anchor portion integrally joined to corresponding ends of said parallel segments and having a straight sharpened edge along that side of the anchor portion away from said segments, the anchor portion being formed from the same unitary wire section used to form the parallel segments and being produced solely by flattening and sharpening such wire section, said anchor portion adapted to be driven by impact into the bone structure forming the alveolar crest.
Claim 2
Dependent Claim
126 words
An endosseal implant for dental prosthesis which requires no incising and pre-drilling of the gum tissue and jaw bone comprising a unitary surgical round metal wire section having a diameter of about one millimeter including a pair of bendable and trimable substantially parallel and substantially equal length segments, and a flattened chisel-like transverse anchor portion integrally joined to corresponding ends of said parallel segments and having a straight sharpened edge along that side of the anchor portion away from said segments, the anchor portion being formed from the same unitary wire section used to form the parallel segments and being produced solely by flattening and sharpening such wire section, said anchor portion adapted to be driven by impact into the bone structure forming the alveolar crest.
Claim 3
Dependent Claim
26 words
An endosseal implant for dental prosthesis as defined in claim 1, wherein the length of said anchor portion and sharpened edge thereof is about four millimeters.
Claim 4
Dependent Claim
26 words
An endosseal implant for dental prosthesis as defined in claim 2, and wherein the length of said implant measured along said segments is about thirty-five millimeters.
Claim 5
Dependent Claim
75 words
An endosseal implant for dental prosthesis as defined in claim 1, and said implant including two side-by-side coupled units each having a flattened sharpened edge anchor portion carried by pairs of spaced parallel wire segments with the inner segments of the pairs joined by a common transverse wire element adapted to rest on the alveolar crest, and said first-named parallel equal length segments extending from and being integral with the outer segments of said pairs.
Claim 6
Dependent Claim
74 words
An endosseal implant for dental prosthesis as defined in claim 1, and said implant including two side-by-side coupled units each having a flattened sharpened edge anchor portion carried by pairs of spaced parallel wire segments with the outer segments of the pairs integrally joined by a common transverse wire element adapted to rest on the alveolar crest, and the interior segments of said pairs extending away from said anchor portions and forming toothed supports.
