Scanner for the determination of a positioning and orientation of a dental implant with a lower part (2) that can be connected with the implant, as well as with a three-dimensional scanning area (4), which for an unequivocal capture of its surface from different Scanning perspectives in relation to a central longitudinal axis (D) of the scanner (1) has a non-symmetrical geometry, where between the lower part (2) and the scanning area (4) there is a displaced passage area (3) from the lower part (2) and the scanning area (4) where the passage area (3) is gradually displaced from the lower part (2) and where the scanning area (4) has a perimeter lateral surface ( 5), which is configured rotationally symmetrically to the central longitudinal axis, characterized by the fact that the perimeter side surface (5) has four sections of the scanner contour (8 to 11) evenly distributed over the perimeter or of the scanning zone, which protrude radially outwardly over an outer contour of the passage zone (3), and which are arranged with each other diametrically facing in pairs, where the sections of the scanner contour are configured respectively of different form each other.Escáner para la determinación de un posicionamiento y orientación de un implante dental con una parte inferior (2) que se puede conectar con el implante, así como con una zona de escaneado tridimensional (4), que para una captación inequívoca de su superficie desde diferentes perspectivas de escaneado con relación a un eje longitudinal central (D) del escáner (1) presenta una geometría no simétrica, donde entre la parte inferior (2) y la zona de escaneado (4) está prevista una zona de paso (3) desplazada de la parte inferior (2) y la zona de escaneado (4) donde la zona de paso (3) está desplazada de forma gradual de la parte inferior (2) y donde la zona de escaneado (4) presenta una superficie lateral perimetral (5), que se configura de forma rotacionalmente simétrica al eje longitudinal central, caracteriza
