Abstract
A dental implant includes an upper connector portion and lower implantation portion, the connector portion receiving a dental crown or similar prosthesis, the implantation portion having rectangular cross section and linear vertical profile with machine taper. An outer surface of the implantation portion provides frictional fit with a correspondingly shaped surrounding bone surface. A bone removal tool includes a hand-held actuator generating high-frequency, small-amplitude vibration, and an attached metal tool tip having elongated head portion and curved neck portion. The head portion has rectangular cross section and linear taper, and an outer surface of the head portion has a saw-toothed grinding pattern for removing bone. The neck portion is dimensioned and configured to establish mechanical resonance of the tool tip including axial reciprocating action of the head portion in response to the actuator vibration.
