Patent ID: 8632337

Claim:
A method to determine a position of a dental implant ( 2 ) having a central axis ( 10 ), said dental implant being fixed in the bone of the jaw ( 13 ) of a person, comprising the steps of: after having fixed the implant into the bone of the jaw, fixing at least one marker element ( 3 ) which produces a strong contrast in imaging techniques to a free end ( 1 ) of said implant ( 2 ) in a detachable manner to situate the marker element ( 3 ) at a distance (d) from the free end ( 1 ), generating an image of the jaw or of a reproduction model of the jaw by means of X-rays or magnetic resonance, wherein the jaw contains the implant ( 2 ) with said marker element, determining the position of the marker element ( 3 ) in relation to the jaw on the basis of said image which is formed by said X-rays or by said magnetic resonance, and identifying the position of said implant ( 2 ) from an observed position of the marker element ( 3 ); and determining the position of the dental implant in relation to the jaw comprising calculating an exact position of the implant on a longitudinal axis of the implant on the basis of a previously determined distance between the marker element and the free end of the implant.
