Abstract
Abstract An angled abutment adapted for use with an endosseous dental implant includes two parts, a first part having a platform joined to a downwardly-projecting post with screw threads on its outer surface adapted for engagement in an internally-threaded shaft at the top of an endosseous dental implant, and a second part that includes an angled head joined to a shaft that projects downwardly from the head and is adapted for insertion and for cementing into the downwardly-projecting passage in the platform of the first part.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
117 words
An angled abutment adapted for use with an endosseous dental implant anchoring means includes a first part and a second part wherein the first part comprises platform means joined to downwardly-projecting post means having screw threads on the outer surface of said post means, said threaded post means being adapted for engagement in an internally-threaded shaft at the top of an endosseous dental implant, and said second part comprising angled head means joined to shaft means having at least one flat side and projecting downwardly from said angled head means, said angled head means being adapted for insertion and for cementing into a downwardly-projecting passage in said platform means, said passage including a plurality of flat sides.
Claim 2
Dependent Claim
117 words
An angled abutment adapted for use with an endosseous dental implant anchoring means includes a first part and a second part wherein the first part comprises platform means joined to downwardly-projecting post means having screw threads on the outer surface of said post means, said threaded post means being adapted for engagement in an internally-threaded shaft at the top of an endosseous dental implant, and said second part comprising angled head means joined to shaft means having at least one flat side and projecting downwardly from said angled head means, said angled head means being adapted for insertion and for cementing into a downwardly-projecting passage in said platform means, said passage including a plurality of flat sides.
Claim 3
Dependent Claim
20 words
The angled abutment of claim 1 wherein said second part has a tapered shape to accept a cemented dental prosthesis.
Claim 4
Dependent Claim
29 words
The angled abutment means of claim 1 wherein said head means has a threaded passage in its upper surface to accept a fixation screw for a detachable dental prosthesis.
Claim 5
Dependent Claim
64 words
The angled abutment of claim 1 further comprising means atop said first part, and at the bottom of said second part, that are complementary in size and shape, and that join sealingly when said first part is seated in said second part to substantially prevent inflow of solids and liquids into the space between the first and second parts when they are joined together.
Claim 6
Dependent Claim
30 words
The angled abutment of claim 1 wherein the second part forms an angle of approximately 15° with respect to the longitudinal axis of said post means in said first part.
Claim 7
Dependent Claim
30 words
The angled abutment of claim 1 wherein the second part forms an angle of approximately 30° with respect to the longitudinal axis of said post means in said first part.
Claim 8
Dependent Claim
30 words
The angled abutment of claim 1 wherein the second part forms an angle of approximately 40° with respect to the longitudinal axis of said post means in said first part.
Claim 9
Dependent Claim
69 words
A first part of an angled abutment adapted for use with an endosseous dental implant anchoring means comprises platform means joined to downwardly-projecting post means having screw threads on the outer surface of said post means, said platform means including an opening leading to an internal passage, said passage including a plurality of flat sides and being adapted to receive and engage a second part of said angled abutment.
Claim 10
Dependent Claim
69 words
A first part of an angled abutment adapted for use with an endosseous dental implant anchoring means comprises platform means joined to downwardly-projecting post means having screw threads on the outer surface of said post means, said platform means including an opening leading to an internal passage, said passage including a plurality of flat sides and being adapted to receive and engage a second part of said angled abutment.
