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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a fixation pin for a dental template, to a set including the fixation pin and to its use for fixing a dental drill template.BACKGROUND[0002]In dentistry it is well known to replace either missing teeth or carious teeth where the progress of caries is such that they cannot be fixed in another, less invasive way. Said missing teeth are usually replaced by an endosseous implant with an artificial supra-structure. While quite a lot research has been done to improve the dental implants themselves, tools and devices which aid in planning the implantation and during the surgical intervention have long been neglected. However in recent years such aiding devices have become more and more important.[0003]For instance, the drilling of the hole necessary for the endosseous part of the dental implant has been simplified. While at the beginning the drilling of the hole was purely dependent on the skill of the individual surgeon, there a...

AI Technical Summary

Benefits of technology

This patent describes a fixation pin that simplifies the process of fixing a drill template in a patient's mouth for dental implant placement. The fixation pin is easy to use, fast, and reliable. It provides a secure fixation without the need for screwing or damage to the bore hole, and prevents unwanted particles or liquids from entering. The head of the fixation pin has a good grip to prevent slipping or dropping. The fixation pin is made of titanium or stainless steel, which are both stable and biologically inert. The invention also includes a method for using the fixation pin for securing drill templates with at least two bore holes.

Problems solved by technology

In contrast, multiple insertions of a rod having a screw thread is likely to damage the bore hole and thus hamper the subsequent insertion of a dental implant such that the implantation is unsuccessful because of poor asseointegration of the implant.

Further, the bearing surface of the head of the fixation pin may provide a physical stop limiting the depth the fixation pin may be inserted into drill template (or drill sleeve provided in the drill template), thereby also limiting the depth by which the fixation pin extends into the bore hole that has been drilled into the jaw bone.
