Abstract
Abstract A frame portion is implanted in a correspondingly shaped upwardly extending channel cut longitudinally in the alveolar ridge of the upper jaw. The frame portion has a rear extension arranged to project through an aperture cut in the pterygoid bone and more particularly in an aperture cut just above the pyramidal process. Support means are provided on the main frame portion for connecting denture means thereto. The frame portion may be Ushaped if desired to extend fully around the alveolar ridge from pterygoid bone to pterygoid.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
104 words
A permanent implant support frame for an upper denture comprising a. a frame portion having forward and rearward ends, b. said rearward end including an extended shank portion, c. said frame portion forward of said extended shank portion being shaped longitudinally so as to be insertable in a channel cut longitudinally in the alveolar ridge of the upper jaw and said shank portion being of a length to extend through an aperture cut longitudinally in the pterygoid bone to accomplish a permanent implant mounting in the jaw, d. and depending support means on said frame portion arranged for connection thereto of artificial denture means.
Claim 2
Dependent Claim
104 words
A permanent implant support frame for an upper denture comprising a. a frame portion having forward and rearward ends, b. said rearward end including an extended shank portion, c. said frame portion forward of said extended shank portion being shaped longitudinally so as to be insertable in a channel cut longitudinally in the alveolar ridge of the upper jaw and said shank portion being of a length to extend through an aperture cut longitudinally in the pterygoid bone to accomplish a permanent implant mounting in the jaw, d. and depending support means on said frame portion arranged for connection thereto of artificial denture means.
Claim 3
Dependent Claim
35 words
The support frame of claim 1 wherein said shank portion is angled upwardly relative to the general longitudinal line of said frame portion in order to extend through the pterygoid bone above the pyramidal process.
Claim 4
Dependent Claim
20 words
The support frame of claim 1 wherein said frame portion has horizontal perforations therethrough to facilitate bone growth connection thereto.
Claim 5
Dependent Claim
41 words
The support frame of claim 1 wherein said frame portion is U-shaped, having a curved front end similar to the curvature of the alveolar ridge of the jawbone and side extensions terminating in one of said shank portions on each side.
Claim 6
Dependent Claim
43 words
The support frame of claim 4 wherein the curved front end of said frame portion is inclined rearwardly toward the bottom to provide a hooking engagement with a correspondingly inclined wall in the channel cut in the anterior portion of the alveolar ridge.
Claim 7
Dependent Claim
36 words
The support frame of claim 1 wherein said support means comprises an auxiliary bar selectively contoured for holding the artificial denture means, and upright posts securing said frame portion and said auxiliary bar in spaced relation.
Claim 8
Dependent Claim
31 words
The support frame of claim 1 wherein said support means comprises a plurality of integral posts extending downwardly at selected angles and at selected locations for securement thereto of denture means.
Claim 9
Dependent Claim
32 words
The support frame of claim 1 including at least one implant post projecting upwardly from said frame portion at the front thereof for engagement in sockets cut upwardly in the jaw bone.
Claim 10
Dependent Claim
74 words
The process of implanting a bar-like frame in the upper jaw for securing denture means thereto comprising first cutting a channel in the bone along the alveolar ridge of the upper jaw as well as cutting an aperture in the pterygoid bone above the pyramidal process in alignment with said channel, and then inserting the bar-like frame in the channel with a rearward extended shank portion of the bar-like frame extending into said aperture.
Claim 11
Dependent Claim
74 words
The process of implanting a bar-like frame in the upper jaw for securing denture means thereto comprising first cutting a channel in the bone along the alveolar ridge of the upper jaw as well as cutting an aperture in the pterygoid bone above the pyramidal process in alignment with said channel, and then inserting the bar-like frame in the channel with a rearward extended shank portion of the bar-like frame extending into said aperture.
Claim 12
Dependent Claim
32 words
The process of claim 9 wherein thE rearward extended shank portion of the bar-like frame bears upwardly against a pyramidal process of the pterygoid bone in the installed position of the frame.
Claim 13
Dependent Claim
35 words
The process of claim 10 wherein the channel is cut around the alveolar ridge from one pterygoid bone to the other for inserting a barlike frame that extends fully the length of the upper jaw.
