Ultra-slim dental implant fixtures

摘要

Dental implant fixtures having external diameters less than 3.0 mm., and external threads which are deeper at the apical end of the fixture than elsewhere are described. The deeper threads near the apical end serve to pull the fixture into a prepared bore in the patient's jawbone. There results a firm close contact between the fixture and the host bone to promote osseointegration. Ultra-slim implant fixtures are provided which can be used in thin sections of human jawbone where dental implants were previously contra-indicated.
