Fixation pin

Abstract

Fixation pin ( 1 ) for fixing a dental drill template. The fixation pin ( 1 ) has a head ( 5 ) having a bearing surface ( 10 ) that is intended to bear at least partially on the drill template, or a sleeve provided in the drill template. The fixation pin ( 1 ) has a rod ( 15 ) having a shape of an essentially circular cylinder and which extends from the bearing surface ( 10 ) at an essentially right angle. The rod ( 15 ) is intended to be inserted into the drill template or the sleeve provided in the drill template.

What is claimed is: 
     
         1 . A fixation pin for fixing a dental drill template, the fixation pin comprising:
 a head having a bearing surface configured to bear at least partially on the drill template or a sleeve provided in the drill template, the head including a peripheral indentation; and   a rod having a shape of an essentially circular cylinder, the rod having a first end at the bearing surface and a second free end, the rod extending from the bearing surface of the head at an essentially right angle, the rod being configured to be inserted into the drill template or the sleeve provided in the drill template, the rod having a substantially smooth cylindrical outer surface from the first end to the second end.   
     
     
         2 . The fixation pin according to  claim 1 , wherein the head has a shape of an essentially circular cylinder. 
     
     
         3 . The fixation pin according to  claim 1 , wherein the peripheral indentation has a concave shape. 
     
     
         4 . The fixation pin according to  claim 1 , wherein the rod has a first portion extending from the bearing surface of the head, and a second portion extending from the first portion to the second end, wherein the second portion has a diameter that is less than a diameter of the first portion. 
     
     
         5 . The fixation pin according to  claim 4 , wherein the first portion of the rod is connected to the second portion by an intervening third portion, the third portion having a conical shape. 
     
     
         6 . The fixation pin according to  claim 1 , wherein the fixation pin is made of one single piece. 
     
     
         7 . The fixation pin according to  claim 1 , wherein the fixation pin is made of a material selected from the group consisting of hard plastics, stainless steel, titanium, and titanium alloys. 
     
     
         8 . The fixation pin according to  claim 7 , wherein the fixation pin is made of a material selected from the group consisting of titanium and titanium alloys. 
     
     
         9 . The fixation pin according to  claim 7 , wherein the fixation pin is made of stainless steel. 
     
     
         10 . The fixation pin according to  claim 1 , wherein the fixation pin further comprises an aspiration security member. 
     
     
         11 . The fixation pin according to  claim 10 , wherein the aspiration security member is a string attached to the head of the fixation pin. 
     
     
         12 . A set comprising two or more of the fixation pins according to  claim 1 . 
     
     
         13 . The fixation pin according to  claim 1 , wherein the first end of the rod interfaces with the bearing surface at a right angle. 
     
     
         14 . The fixation pin according to  claim 1 , wherein the head includes a first end and a second end in an axial direction of the head, the first end of the head and the second end of the head being connected by the peripheral indentation, the peripheral indentation being a continuous concave-shaped curve. 
     
     
         15 . The fixation pin according to  claim 14 , wherein the first end of the head and the second end of the head have substantially identical diameters. 
     
     
         16 . The set according to  claim 12 , wherein at least one of the two or more fixation pins has a diameter different from another one of the two or more fixation pins. 
     
     
         17 . A fixation pin for fixing a dental drill template, the fixation pin comprising:
 a head having a bearing surface configured to bear at least partially on the drill template or a sleeve provided in the drill template, the head including a peripheral indentation; and   a rod having a shape of an essentially circular cylinder, the rod having a first end at the bearing surface and a second free end, the rod extending from the bearing surface of the head at an essentially right angle, the rod being configured to be inserted into the drill template or the sleeve provided in the drill template, the rod having a cylindrical outer surface that is threadless and grooveless from the first end to the second end.   
     
     
         18 . A fixation pin for fixing a dental drill template, the fixation pin comprising:
 a head having a bearing surface configured to bear at least partially on the drill template or a sleeve provided in the drill template, the head including a peripheral indentation; and   a rod having a shape of an essentially circular cylinder, the rod having a first end at the bearing surface and a second free end, the rod extending from the bearing surface of the head at an essentially right angle, the rod being configured to be inserted into the drill template or the sleeve provided in the drill template, the rod having a cylindrical outer surface without any indentations from the first end to the second end.
