ABSTRACT:
An endosseous implant is disclosed for permanent implantation within a groove formed in the posterior alveolar process in the mandible of the mouth of a patient. The implant comprises a supporting head for supporting a crown portion of an artificial tooth. The supporting head has a substantially horizontal top surface and a base portion. A constricted neck portion is rigidly secured to the base portion for supporting the supporting head. An apertured blade portion is also rigidly secured to the neck portion such that the neck portion connects together the supporting head and the blade portion. The blade portion includes a lingual and a buccal face and a mesial and a distal portion. The mesial portion of the blade portion has a blunt mesial edge and the distal portion has a distal edge of pointed configuration. The neck portion is disposed adjacent the juncture of the mesial and the distal portions and the distal portion is curved away from the longitudinal axis of the mesial portion. In use of the implant, the distal edge is inserted within a groove formed in the alveolar process and the blunt mesial edge is gently hammered so that the distal edge penetrates into the alveolar process towards the Ramus. In an alternative embodiment of the invention, the distal edge is a shallower version of the mesial portion. In a further embodiment of the invention, the supporting head includes a stud which threadably engages a hole defined by the neck portion. In yet a further embodiment of the invention, the supporting head is tilted angularly relative to the neck portion. A further embodiment of the invention includes a conical plug depending from the supporting head, the conical plug cooperating with a correspondingly shaped hole defined by the neck portion.
