Abstract
A juxtaosseous dental implant for application to the mandible or maxilla has a trucated conical post projecting upward from a spider-like base having a central hub portion placed in shielding position over the center of the implantation site and at least three spoke-like branches screwed into the bone at points removed from the site center, thereby providing energy dissipating, multi-directional, three point attachment.
Claims16
A dental implant for use as a bond between a dental prosthesis and the mandible or maxilla bone at an implantation site having crestal, buccal and lingual bone portions, said implant comprising:
- a spider-like base of a material, said base having a central hub region and at least three spoke-like branches extending radially outward at angularly-spaced intervals from said hub region;
- and
- a post projecting upward from said base at said hub region, and dimensioned, configured and adapted to mount the dental prosthesis thereon;
- said hub having a plate-like undersurface dimensioned, configured and adapted to be placed over said crestal bone portion at said implantation site;
- said branches comprising elongated strips having proximal ends integrally connected with said hub region, and distal ends including means for individually securing said distal ends to said bone;
- and
- said branches being dimensioned, configured and adapted, and said material and angularly-spaced intervals being chosen, so that said hub undersurface can be placed over said crestal bone portion and said branches can be drawn longitudinally and bent downward about said implantation site to individually secure them with said securing means at points of attachment to said buccal and lingual bone portions, for establishing a three-point tripod-like connection of said base to said site, providing stability in three spatial directions and against rotation, with said hub region shielding said crestal portion from vertical and
- horizontal forces applied to said post due to the action of mastication and lingual articulation on the received dental prosthesis, and said branches dissipating said forces by dispersing them in multiple directions radially away from said hub region, longitudinally along said branches to said points of attachment.
A process for the implantation of a dental implant on the mandible or maxilla bone at an implantation site having crestal, buccal and lingual bone portions, said implant comprising a spider-like base having a central hub region including a plate-like undersurface, and at least three spoke-like branches extending radially outward at angularly-spaced intervals from said hub region, said branches comprising elongated strips having proximal ends integrally connected with said hub region and distal ends;
- and a post projecting upward from said base at said hub region, said post being dimensioned, configured and adapted to mount the dental prosthesis thereon;
- said process comprising the steps of:
- shaping said implant by drawing said branches longitudinally and bending at least some of said branches downward to conform said implant to the configuration of said implantation site;
- placing said hub region undersurface over said crestal bone portion at said site;
- individually securing said distal ends of said branches at points of attachment to said buccal and lingual bone portions to establish a three-point tripod-like connection of said base to said site, providing stability in three spatial directions and against rotation, with said hub region shielding said crestal portion from vertical and horizontal forces applied to said post due to the action of mastication and lingual articulation on the received dental prosthesis, and said branches dissipating said vertical and horizontal forces by dispersing them in multiple directions radially away from said hub region, longitudinally along said branches to said points of attachment.
