Abstract
An oral surgical instrument (osteotome) for creating openings in the jawbone for the implantation of implants, which comprises a holder, a shaft and a working tip that has a circular cross section. A set of surgical instruments is provided with at least one preformer having a conical working tip and at least one implant bed former having a working tip which is adapted to the outer contour of the implant. The diameter of the working tip of the preformer is somewhat smaller than the largest diameter of the working tip of the implant bed former. By forming the openings in the jawbone using such instruments, the implants may be inserted with a greater fitting strength.
