A method for determining a position and an orientation of a dental implant comprises scanning a surface of a scan body connected to the implant wherein a plurality of data points is determined which correspond to positions of points that are located on the surface of the scan body. The method further comprises reconstructing at least three planes based on the data points, reconstructing intersection information of the reconstructed planes, where the intersection information comprises the reconstruction of straight intersection lines and of intersection points, and determining the position and the orientation of the implant based on the reconstructed intersection information.

L'invention porte sur un procédé de détermination de position et d'orientation d'un implant dentaire, lequel procédé comprend le balayage de la surface d'un corps de balayage relié à l'implant, avec détermination d'une pluralité de points de données correspondant à des positions de point situées sur la surface du corps de balayage. Le procédé comprend en outre la reconstruction d'au moins trois plans sur la base des points de données, la reconstruction d'informations d'intersection des plans reconstruits, les informations d'intersection comprenant la reconstruction de lignes droites d'intersection et de points d'intersection, et la détermination de la position et de l'orientation de l'implant sur la base des informations d'intersection reconstruites.
