  • Patent number: 11744672
    Abstract: The present invention relates to a dental drill (10) formed of titanium or a titanium alloy having a hardness greater than pure titanium, said drill extending along a central axis (A) from a proximal end (14) to a distal end (16). The drill comprises a shank (12) arranged in a proximal end region of the drill (10) and extending along the central axis (A), a flute portion (20) arranged distally to and running coaxially with the shank (12), said flute portion (20) comprising two or more flutes (22a, 22b, 22c) extending along the flute portion (20) and being interposed by lands (24a, 24b, 24c), the flute portion further comprising a central solid web and a drill tip (26) directly adjoining the distal end (28) of the flute portion (20) and comprising two or more flanks (25a, 25b, 25c) which taper radially inwardly from the distal end of each land in the distal direction toward the central axis (A), each flank (25a, 25b, 25c) comprising a cutting edge (30a, 30b, 30c).

  • Patent number: 11730573
    Abstract: A method including fixing a dental drill template with a fixation pin including a rod and a head attached to the rod. The dental drill template can be fixed by inserting the rod into the drill template or a sleeve provided in the drill template such that a bearing surface of the head bears at least partially on the drill template. The rod has a shape of an essentially circular cylinder and extends from the bearing surface of the head at an essentially right angle. A diameter of the head at the bearing surface is larger than the diameter of the rod.

  • Publication number: 20120189980
    Abstract: Combination of a dental implant and an insertion tool for inserting the dental implant into a bone of a patient. The dental implant includes an anti-rotation means having a non-circular cross-sectional contour with at least one planar force transmission surface in the form of an anti-rotation surface (7a, 7b, 7c, 7d). The insertion tool includes an anti-rotation means having a non-circular cross-sectional contour with at least one planar force transmission surface in the form of a torque transmission surface (11a?, 11a?; 11b?, 11b?; 11c?, 11c?; 11d?, 11d?). One of the anti-rotation means forms a recess (6), and the other forms a bolt (10) having a rotational axis and designed to be received in the direction of the rotational axis in the recess (6), such that the at least one anti-rotation surface and at least one torque transmission surface can cooperate to transmit torque between the parts.
