Abstract The invention relates to a dental endosseous root implant with a first part to be completely embedded in and covered over in a tooth socket and a second part carrying a crown or other prosthetic device. The first part has a root portion or dowelreceiving socket on a crown base or platform with an integral surrounding tapered latticed body freely fitting in the tooth socket or prepared bone socket through which bone tissue may grow to embed and secure the dowel-receiving socket in the alveolar process. The second part has a dowel fitting the socket and carries a crown or the like. The implant technique involves selection of a properly sized root implant or dowel-receiving socket to fit freely but snugly into the tooth socket anytime after extraction of the tooth being especially applicable immediately after extraction of the tooth. The gingival tissue over the root implant is then approximated and sutured together. A blood clot fills the socket around the endosseous root implant and is gradually replaced by a fibrous meshwork. The final stage of healing results in continued deposition of bone around and through the latticed body. During the entire period of healing the root implant is under no occlusal or biting stress nor disturbed by the bacterial flora or oral debris since it was completely embedded in the socket and covered over by oral mucosal tissue. The bone tissue embeds the device and the sealed socket is then exposed only at the top of the root implant whereupon the second or more parts including a dowel crown is firmly attached to the root implant.
A dental crown-anchoring device which includes an implant part having a central tubular dowel socket connected in spaced relation to an open lattice cage adapted to be freely but snugly inserted and imbedded in a tooth extraction site, said cage consisting of a top member centrally apertured in communication with the tubular dowel socket, and two laterally spaced struts forming a loop member having its strut lengths depending from the upper area of said tubular dowel socket, said loop member extending longitudinally of the dowel socket and outwardly spaced therefrom, and spaced connecting and reinforcing means projected inwardly from the strut lengths of said loop member across the space between them and the tubular dowel socket and connecting said strut lengths and said tubular dowel socket.
