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.

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). According to the invention, at the distal end of the drill point (26) at least one groove (32, 33a, 33c) is formed in the web such that the distal most end (36a, 36b, 37b, 37c) of at least one of the flanks (25a, 25b, 25c) is located radially remote from the central axis (A).

Abstract: A fixation pin for fixing a dental drill template. The fixation pin has a head having a bearing surface that is intended to bear at least partially on the drill template, or a sleeve provided in the drill template. The fixation pin has a rod having a shape of an essentially circular cylinder and extending from the bearing surface at an essentially right angle. The rod is intended to be inserted into the drill template or the sleeve provided in the drill template.
