Patent ID: RE44800

Claim:
A dental implant for rotation into the bone tissue of a jaw bone consisting of a body having: (a) an axis of rotation; (b) a coronal end surface; (c) an apical end surface; and (d) a generally cylindrical section which has: (i) a coronal edge in close proximity to , the coronal end surface, and (ii) an outer peripheral surface which extends apically , towards the apical end surface from the coronal edge and is presented by a circumferentially-oriented roughness comprising a series of circumferentially-oriented peaks which are axially spaced apart by troughs and oriented at an a generally constant inclined angle with respect to the axis of rotation so the dental implant rotates and screws into the jaw bone ; wherein the height from the troughs to the peaks throughout the circumferentially-oriented roughness is greater than 0.2 mm, and the coronal edge of the generally cylindrical section is separates the generally cylindrical section from a conical portion extending to the coronal edge, the conical portion tapering inwardly as the conical portion extends from the coronal edge to the coronal end surface, the coronal edge and circumferentially-oriented roughness are spaced from the coronal end surface of the body by no more than approximately 4% of the distance between the coronal and apical end surfaces of the body. body, wherein the largest diameter of the dental implant is at the generally cylindrical section.
