Oral implantology

Claim 2

An oral implant comprising a bladevent body adapted for insertion bodily into oral bone structure, at least one abutment post external to bone structure and adapted to project into the oral cavity for supporting an artifical tooth therein, and means directly joined to and supporting said abutment post and adapted to lie beneath gingival tissue and the periosteum and external to bone structure and being joined to the bladevent body, said means comprising a downwardly open frame member having sides and a top spaced from and partly surrounding the bladevent body, said frame member being attached at its top and opposite ends only to the top and opposite ends of the bladevent body at a pair of local small regions on the bladevent body and frame member, said abutment post being attached to the top of said frame at a position spaced from said local small regions, whereby the abutment post is isolated from the bladevent body and connected indirectly therewith only through said frame member.

Claim 3

An oral implant as defined by claim 1, wherein said bladevent body, said abutment post and said means are integrally cast.

Claim 4

An oral implant as defined by claim 2, and wherein said implant is integrally cast from vitallium.

Claim 5

An oral implant comprising a bladevent body adapted for insertion in oral bone structure well beneath the periosteum, a subperiosteal frame member straddling the bladevent body and having sides and a top spaced from the bladevent body, said top of the subperiosteal frame member being joined to the bladevent body locally at the ends only of the bladevent body, and an abutment post secured to the top of and rising from the subperiosteal frame member, whereby the abutment post is indirectly joined to the bladevent body through said subperiosteal frame member, said subperiosteal frame member being of inverted U-shaped form and downwardly open between its sides and said sides being equidistantly spaced from opposite sides of the bladevent body, the bladevent body having a substantially sharp longitudinal edge between said sides, said subperiosteal frame member having end and intermediate U-shaped frame sections and lower longitudinal side bars interconnecting said frame sections, said abutment post being secured to the top of said intermediate frame section.

Claim 6

An oral implant comprising a bladevent body adapted for insertion in oral bone structure well beneath the periosteum, a subperiosteal frame member straddling the bladevent body and having sides and a top spaced from the bladevent body, said top of the subperiosteal frame member being joined to the bladevent body locally at the ends only of the bladevent body, and an abutment post secured to the top of and rising from the subperiosteal frame member, whereby the abutment post is indirectly joined to the bladevent body through said subperiosteal frame member, said subperiosteal frame member being of inverted U-shaped form and downwardly open between its sides and said sides being equidistantly spaced from opposite sides of the bladevent body, the bladevent body having a substantially sharp longitudinal edge between said sides, said subperiosteal frame member having end and intermediate U-shaped frame sections and lower longitudinal side bars interconnecting said frame sections, said abutment post being secured to the top of said intermediate frame section.

Claim 7

An oral implant as defined by claim 4, in which said bladevent body, said subperiosteal frame member and said abutment post are all integrally cast as a unitary body.

Claim 8

An oral implant as defined by claim 5, and said implant formed from surgical vitallium or metal of equivalent composition and bio-compatability.

Claim 9

An oral implant as defined by claim 4, and said bladevent body joined to said subperiosteal frame member at the tops of said end U-shaped frame sections.
