ABSTRACT:
A dental implant is described which has greater stability in the jawbone and greatly reduces the potential for infection. The implant is made from an anatomically precise reproduction of the affected site of the jawbone, which reproduction is produced from computer generated data defining the affected site. The reproduction is used as the base for a cutting jig to fit on an exposed mandible or maxilla and the jig is used to route out a channel which will accommodate the implant. The technique allows the identification and location of sinuses, nerves, and compact bone and thus favors the placement of anchoring means in appropriate areas.
