Dowel-shaped element for determining spatial position

Abstract

A post-shaped element for determining the alignment of an implant (1), or the opening cross-section of an artificial indentation located in a tooth or in the stroma of a human or animal body, relative to the surrounding tissue structures, can be introduced with a receiving section (28, 26A) into an adapted receiving recess (10) in the implant (1) or the artificial indentation, and be affixed therein and removed again. In a connecting position the post-shaped element protrudes with a cantilever section (26K) beyond the opening cross-section of the receiving recess (10) or the artificial indentation. In order to be able determine the correct position of the post-shaped element in relation to the implant (1) in a simple and reliable manner without X-ray images, it is suggested that the post-shaped element contain a through-hole extending in the direction of its longitudinal axis, through which a rod device (32) can be guided, which with a distal stop surface (36) can be brought into contact with a stop surface (37) on the base of the receiving recess (10) of the implant (1).

Description

technical field [0001] The invention relates to a columnar element for determining the spatial position of an implant (1), either in a tooth or in supporting tissue of the human or animal body The spatial position of the opening cross-section of the artificial groove relative to itself or its surrounding tissue structure. Here, the columnar element can be inserted into the matching fastening groove with a fastening section, and the columnar element is implanted in the implant or artificial groove. In the groove, the cylindrical element can be fastened securely in a twisted manner and can also be removed again, while said cylindrical element has a cantilever section above the opening cross-section of the fastening groove or the artificial groove. Background technique [0002] A columnar element of the type described in the field of dentistry is called a mold column, with which it is possible, for example, to determine the state and position of a dental medical implant before ...

AI Technical Summary

Problems solved by technology

[0004] From the above, the existing mold pillars have the following disadvantages, that is, during the implantation process and before molding, there are no further measures of determination to determine the exact position of the mold pillar relative to the implant, so it is entirely possible, in mutual Between the interface between the mold post and the implant that is already in place, e.g., the insertion of adjacent tissue into the implant, so that the correct positioning between the mold post and the implant is not possible, in which case fixation by casting Incorrect position of the mold post, resulting in the connection of the mold post to the wrong position of the implant

[0005] To avoid this unreliability, the exact position of the mold post is monitored by means of X-ray imaging after it has been fixed on the implant and before the molding is made, which will lead to increased installation time and thus This increases the cost of the implant system and also brings radiation damage to the patient, although the damage is as small as possible according to the current level of knowledge and technology.
