Abstract

A stress stabilizer for a dental implant is formed by an inverted substantially U-shaped saddle for straddling an intermediate portion of an alveolar ridge of a mandible in contiguous contact with cortical bone. The bight portion of the U-shape is bored and counterbored from respective ends of the bore for alignedly guiding prosthesis components secured together through the saddle bore by a pin.

Claims

1. A dental implant stabilizer, comprising:

a sleeve implant for vertically entering an opening formed in

the alveolar ridge of a mandible;

saddle means including a strap-like inverted substantially U-shaped saddle having a centrally bored bight portion counterbored from each end of the central bore and having depending legs for overlying the implant and straddling an intermediate portion of the alveolar ridge in contiguous contact with cortical bone and seated on said implant; and

,

prothesis means including a guide received by the counterbore opposite the implant and connected with the implant and supported by the saddle means.

2. The stabilizer according to claim 1 in which the prosthesis means includes:

a tooth disposed on said saddle and having an aperture axially aligned with the saddle bore; and

,

pin means for securing the tooth to said implant.

3. The stabilizer according to claim 2 in which the prosthesis further includes:

a centrally apertured step diameter sleeve-like abutment interposed between said tooth and said guide.

4. A dental implant stabilizer, comprising:

a sleeve implant for vertically entering an opening formed in the alveolar ridge of a mandible;

guide means including a strap-like inverted substantially U-shaped saddle having a centrally bored bight portion and depending legs for overlying the implant and straddling an intermediate portion of the alveolar ridge in contiguous contact with cortical bone; and

,

prothesis means connected with the implant and supported by the saddle means;

said prothesis means including;

a tooth disposed on said saddle and having an aperture axially aligned with the saddle bore,

pin means for securing the tooth to said implant,

a centrally apertured step diameter sleeve-like abutment interposed between said tooth and said saddle, and,

a centrally bored guide having a top portion nested by the abutment and having an outstanding annular flange overlying the saddle bight portion,

the saddle bore being counterbored from each end for nesting the adjacent end portion of said implant and the guide flange, respectively.
