Abstract
Abstract A kit for forming a number of different forms of prosthetic devices to replace different portions of a mandible which have been removed. The kit includes a number of prefabricated members, fabricated from a malleable stainless steel mesh, including mating inner and outer tubular sleeve portions for assembling adjoining members, with the sleeve portions being crimped together to define rigid couplings. Screws are used to attach the end member of an assembled prosthetic device to the bone stump of the remaining mandible.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
Mandibular prosthetic apparatus comprising, in combination: an assembly of members fabricated of a malleable mesh; a bow member for replacing at least portions of the main body of a mandible; said bow member comprising an elongated curved member, elongated in cross section, and formed to include an elongated cylindrical socket portion along one edge thereof defining an outer mating circular sleeve; a first bow support member comprising a body portion and a tubular portion extending therefrom; said tubular portion defining an inner mating circular sleeve dimensioned for sliding fit with the outer mating circular sleeve of the bow member; said bow member outer mating sleeve fully receiving and enclosing said support member inner mating sleeve, for coupling said members.
Claim 2
Dependent Claim
119 words
Mandibular prosthetic apparatus comprising, in combination: an assembly of members fabricated of a malleable mesh; a bow member for replacing at least portions of the main body of a mandible; said bow member comprising an elongated curved member, elongated in cross section, and formed to include an elongated cylindrical socket portion along one edge thereof defining an outer mating circular sleeve; a first bow support member comprising a body portion and a tubular portion extending therefrom; said tubular portion defining an inner mating circular sleeve dimensioned for sliding fit with the outer mating circular sleeve of the bow member; said bow member outer mating sleeve fully receiving and enclosing said support member inner mating sleeve, for coupling said members.
Claim 3
Dependent Claim
43 words
The invention set forth in claim 1 including an elongated curved lip member having a U-shaped cross section; said lip member dimensioned to partially enclose the bow member to define a lateral extension of the bow member cross section in the bow area.
Claim 4
Dependent Claim
44 words
The invention set forth in claim 1 wherein said first bow support member defines a retention member for securing the bow member to a mandible stump; said support member body portion being formed to enclose a portion of the mandible stump for attachment thereto.
Claim 5
Dependent Claim
52 words
The invention set forth in claim 1 wherein said first bow support member comprises a ramus-condyle member for replacing the ramus and condyle of the mandible; the body portion of said ramus-condyle member being elongated and having means for attaching an artificial condyle at the end remote from the tubular extension portion.
Claim 6
Dependent Claim
22 words
The invention set forth in claim 4 wherein said tubular extension portion extends at an angle relative to said elongated body portion.
Claim 7
Dependent Claim
121 words
The invention set forth in claim 1 wherein said first bow support member comprises a ramus-condyle assembly including a ramus member and a condyle member; said ramus member comprising an elongated tubular body portion of elongated cross section, defining an inner mating oval sleeve, and said tubular extension portion, defining said inner mating circular sleeve; said condyle member comprising an elongated tubular body of elongated cross section, defining an outer mating oval sleeve, and an artificial condyle attached to one end of said tubular body; said outer mating oval sleeve being dimensioned for a sliding fit with said inner mating oval sleeve and receiving and enclosing said inner oval sleeve to provide a rigid coupling between the ramus and condyle members.
Claim 8
Dependent Claim
54 words
The invention set forth in claim 6 wherein said tubular extension portion of said ramus member extends at an angle relative to the elongated tubular body portion of said member; and wherein said outer and inner oval sleeves are deformed in interfering relation to provide the rigid coupling between the ramus and condyle members.
Claim 9
Dependent Claim
126 words
The invention set forth in claim 1 including a second bow support member defining a retention member for securing the bow member to a mandible stump in the bow area of a mandible; said second bow support member comprising a body formed to enclose a portion of the mandible stump for attachment thereto; said body including a socket portion defining an outer mating circular sleeve; and a connector member comprising an elongated curved tubular member of circular cross section, defining an inner mating circular sleeve dimensioned for a sliding fit with the outer mating circular sleeves of the bow member and the second support member; said connector member being fully enclosed within said outer mating sleeves to couple said bow member to said second support member.
Claim 10
Dependent Claim

The invention set forth in claim 1 wherein said first bow support member defines a retention member for securing the bow member to a bone stump in the bow area of the mandible; said bow support member comprising a body formed to enclose a portion of the mandible stump for attachment thereto; said body including a socket portion defining an outer mating circular sleeve; and a connector member comprising an elongated curved tubular member of circular cross section, defining an inner mating circular sleeve dimensioned for a sliding fit with said socket portion outer mating circular sleeve; said connector member defining said bow support member tubular portion.
Claim 11
Dependent Claim
75 words
The invention set forth in claim 1 wherein said bow member is severed to provide two abutting segments; and a curved connector member comprising an elongated curved tubular member of circular cross section dimensioned to define an inner mating circular sleeve for sliding fit with the outer mating circular sleeves of the two bow member segments, with the connector member being fully received in and enclosed by said bow member segments to couple said segments.
Claim 12
Dependent Claim
27 words
The invention set forth in claim 1 said inner and outer mating sleeves being deformed in interfering relation to provide a rigid coupling between the respective members.
Claim 13
Dependent Claim
31 words
The invention set forth in claim 10 said curved connector member and said bow member segments being deformed in interfering relation to provide a rigid coupling between the bow member segments.
