Patent ID: 8142190

Claim:
A method of preparing a dental implant site in bone, said method comprising: (i) piercing the hardest outer layer of the bone with a starter drill to create a hole; (ii) drilling the hole with an additional drill of a different diameter that has an end for connection to a surgical motor; (iii) expanding the hole with an atraumatic bone osteotome engaged with one of a motor-driven connector or a manual driven-connector; and (iv) repeating steps (ii) and (iii) one or more times to define a cavity to house dental implant, in which steps (ii) and (iii) are performed successively and alternately, and each step (ii) uses an additional drill of a different diameter and each step (iii) uses atraumatic bone osteotomes of progressive diameters; wherein the starter drill comprises a quadrangular-section drilling end that is shorter in length and smaller in section than the osteotomes, that pierces the hardest outer layer of the bone, and an end for engagement to the surgical motor; and the osteotomes each have an apical end followed by a threaded conical section and a threaded cylindrical section, with the threaded cylindrical section capped by an adjustment area in which the connectors are engaged.
