A fixation pin for fixing a dental drill template, comprising:
- a head having a circumventing indentation, and a bearing surface configured to bear at least partially on the drill template or a sleeve comprised in the drill template, and
- a rod having a shape of an essentially circular cylinder and extending from the bearing surface of the head at an essentially right angle, the rod having an outer surface that is free of a screw thread, and being intended to be inserted into the drill template or the sleeve comprised in the drill template, the rod consisting of:
- a first portion extending from the bearing surface of the head and having a diameter that is constant along a length of the first portion, height marks being arranged on the first portion of the rod,
- a subsequent second portion having a length extending between a first end and a second free end, the second portion having a diameter that is constant along the length between the first end and the second free end, the diameter of the second portion being smaller than the diameter of the first portion, and
- an intervening third portion that connects the first portion and the second portion, said third portion having a conical shape,
- wherein a diameter of the head at the bearing surface is larger than a diameter of the first portion of the rod.
