Abstract
Abstract A prosthetic implant attachment system for mounting a dental prosthesis on a root implant including a base member having a lower end sized to seat on the upper end of an implant cylinder and an upper end of outer diameter substantially equal to the average outer diameters of various teeth, a securing device for securing the base member on the root implant, and various straight, angled or variable angled prosthetic heads for securing to the prosthesis. The upper end of the base member and the lower end of the prosthetic head have interengageable and indexable locking formations for preventing rotation between the parts which can be engaged in any of a number of possible relatively rotated fixed, indexed positions. A releasable securing device secures the prosthetic head to the base member. The prosthesis can be mounted on the prosthetic head by cementation, screw fixation, or other techniques. A system for preventing rotation of the base member on an implant cylinder is set forth as is an improved analogue pin that is removable from the model. An implant system with an orthodontic bracket is also described.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
A prosthetic implant attachment system for mounting a prosthetic device to the jaw bone in the mouth comprising a base member, securing means associated with said base member for permitting said base member to be secured to the jaw bone in said mouth, said base member and said securing means having threaded portions for permitting said base member to be threadably connected to said securing means, and means for preventing rotational movement between said base member and said securing means, said means for preventing rotational movement between said base member and said securing means comprising a hole in the threaded portion of said base member, a hole in the threaded portion of said securing means and a pin member locatable in the holes in the threaded portion of said base member and the threaded portion of said securing means for engaging said base member and said securing means after said base member has been threadably connected to said securing means.
Claim 2
Dependent Claim
160 words
A prosthetic implant attachment system for mounting a prosthetic device to the jaw bone in the mouth comprising a base member, securing means associated with said base member for permitting said base member to be secured to the jaw bone in said mouth, said base member and said securing means having threaded portions for permitting said base member to be threadably connected to said securing means, and means for preventing rotational movement between said base member and said securing means, said means for preventing rotational movement between said base member and said securing means comprising a hole in the threaded portion of said base member, a hole in the threaded portion of said securing means and a pin member locatable in the holes in the threaded portion of said base member and the threaded portion of said securing means for engaging said base member and said securing means after said base member has been threadably connected to said securing means.
Claim 3
Dependent Claim
45 words
The prosthetic implant attachment system of claim 1 wherein said pin member has a head portion with a notch for use in removing said pin member from the holes in the threaded portion of said base member and the threaded portion of said securing member.
Claim 4
Dependent Claim
93 words
An implant analogue system for use in forming an artificial tooth for a dental implant comprising an impression head and a tapered pin member having a lower end portion and having an integral enlarged head portion sized and shaped to substantially correspond to said impression head and tapering generally from the integral enlarged head portion to the lower end portion with a substantially flat inclined surface located on a portion of the tapering portion of said pin member with the inclined surface sloping inward toward the lower end portion of said pin member.
Claim 5
Dependent Claim
93 words
An implant analogue system for use in forming an artificial tooth for a dental implant comprising an impression head and a tapered pin member having a lower end portion and having an integral enlarged head portion sized and shaped to substantially correspond to said impression head and tapering generally from the integral enlarged head portion to the lower end portion with a substantially flat inclined surface located on a portion of the tapering portion of said pin member with the inclined surface sloping inward toward the lower end portion of said pin member.
Claim 6
Dependent Claim
17 words
