Abstract
A mandibular prosthesis includes a pair of strips joined at one end and spaced apart elsewhere for placement on opposite sides of a mandibular stump. The strips each have alternating threaded and non-threaded holes that are aligned with respective non-threaded and threaded holes in the other strip. Consequently, screws can be applied from either side and the prosthesis can be implanted interchangeably on either side of the mandible. Extending from the joined end of the strips is a mandibular replacement which may be an artificial condyle, a band for replacing the main body of the mandible, or a band carrying additional attachment strips or a ramus and condyle replacement.
Claims13
A mandibular prosthesis comprising:
- a pair of strips joined at one end and spaced apart away from said one end for placement on opposite side of a mandibular stump located adjacent a damaged portion of the mandible;
- a mandibular replacement extending from said one end of the strips for replacing the damaged portion of the mandible;
- said mandibular replacement having an artificial condyle;
- a plurality of openings in each strip aligned with openings in the other strip, at least some of said openings being internally threaded;
- and
- a plurality of externally threaded fasteners for extension between said trips and through the stump to attach said mandibular replacement in a position to replace the damaged portion of the mandible, each fastener having a size and length to pass through an aligned pair of openings and thread into one of the internally threaded openings to maintain said strips against the opposite sides of the stump.
A mandibular prosthesis comprising:
- a bifurcated body having first and second strips joined at one end and spaced apart away from said one end for placement on opposite sides of a mandibular stump located adjacent a damaged portion of the mandible which is to be replaced by the prosthesis, said body further having a mandibular replacement extending from said one end and adapted to replace the damaged portion of the mandible;
- said mandibular replacement having an artificial condyle;
- a row of openings in each strip including alternating threaded and non-threaded openings, each threaded opening in the first strip being aligned with a non-threaded opening in the second strip and each non-threaded opening in the first strip being aligned with a threaded opening in the second strip;
- and
- a plurality of threaded fasteners each adapted to extend through a non-threaded opening and the mandibular stump and to thread into a threaded opening, whereby the fasteners can be applied from either the side of the body which presents the first strip or the side of the body which presents the second strip to attach the body to the stump with said strips maintained against the opposite sides of the stump.
