Abstract
A subperiosteal implant has a prefabricated elongated plate of pliable, work-hardenable material. A short projection extends from one surface of the plate and defines an aperture which receives a post for supporting an artificial tooth structure. The prefabricated implant is inserted through a lateral incision in the gum tissue, and is then molded to the bone. Subsequently the incision is sutured and the post is installed on the support plate.
Claims6
A prefabricated subperiosteal implant for supporting an artificial tooth structure, comprising:
- two thin elongated plates of pliable, work-hardenable material;
- short protrusions from the surface of each plate;
- means for fastening said two plates together such that the two plates are aligned and the short protrusions are adjacent one another;
- and
- a post for supporting an artificial tooth structure, said post being adapted for attachment to said short protrusions.
A prefabricated subperiosteal implant for retaining an artificial removable full arch denture plate for a totally edentulous jawbone comprising;
- at least two thin elongated sheets of pliable work-hardenable material adapted to be positioned in respective spaced-apart locations along the edentulous jawbone beneath the periosteum and molded to the jawbone;
- and
- first and second magnetically susceptible materials at least partially covering said sheets and said denture plate, respectively, said second material being in the form of at least one magnet which is attracted to said first material in said sheets to hold the plate in place.
A method of inserting a subperiosteal implant on the dental bone ridge of a patient, comprising the steps of:
- making a lateral incision in the tissue covering the bone ridge, said incision extending across the bone ridge;
- tunneling the tissue such that it separates from the bone ridge both mesially and distally from the incision, the mesial and distal distance of the tunneled tissue being equal to the respective lengths of a two-part prefabricated implant;
- sliding first one, then the other, of the two parts of the implant under the tissue in the respective mesial and distal directions;
- securing the two parts of the implant together;
- molding the implant to the bone under the tissue;
- suturing the incision;
- and
- subsequently installing a post on the prefabricated implant.
