Abstract: A system for a dental superstructure to be attached to an implant using a digital model description of a shape of the superstructure, the superstructure including first and second elements. The system comprises a computing device arranged to (a) analyze a recorded real clinical situation or shaped clinical situation of an implant axis and insertion axis, (b) compute a shape of the dental superstructure based at least in part on the determined implant axis, (c) generate digital data representing the shape of the superstructure, and (d) separate the computed shape into first digital data representing a shape of the first element to be connected to the implant and second digital data representing a shape of the second element to be connected to the first element, the shape of the first element being optimized, at least in part, based on a tilt angle between the determined implant axis and insertion axis.

Abstract: The invention relates to a method for automatically creating a dental superstructure for joining to an implant based on a digital model description of the shape. To this end: the actual clinical situation or an arranged clinical situation of the implant (3; 13) is recorded in the form of digital data; this situation is analyzed; the implant axis (5; 16) is determined; the optimal shape of the superstructure (1, 2) is calculated while taking a set of structural rules into account, and; a production machine is used for producing the individual parts from at least one blank (11) based on the digital data.

Abstract: The invention relates to a method for precisely-positioned production of a cavity, especially a bone cavity, at a preparation point by means of a hand instrument, comprising the following steps: calculation of position-dependent surface characteristics from a three-dimensional data set of the surface of the preparation point at a desired position of an implant which is to be inserted in said cavity, wherein the area in which the cavity is to be created is represented in the form of a three-dimensional data set of volume data; detection of at least one partial cut-out of the preparation point comprising an actual visible surface feature by means of a camera which is arranged on the hand instrument at a pre-defined distance to a processing tool and display as a video image; insertion of a calculated surface characteristic for the desired position of the hand instrument, wherein the inserted surface characteristic can be altered, especially made congruent with respect to its position in relation to the actual vi
