Method for planning a medical implant and construction of dental prostheses based thereon and drilling template for preparing a bone for a medical implant

摘要

The method for planning a medical implant comprises the following steps: producing a prosthesis which is adapted to at least one partial region of a body part, the prosthesis having at least two reference markers, creating at least one transverse tomogram of the at least one partial region of the body part during the preparation of the recordings, the prosthesis is placed on the body part such that the at least two reference markers of the prosthesis are recognizable in at least one of the transversal tomograms, segmenting the at least one transverse tomogram and creating a digital three-dimensional model of at least part of the at least one a partial region of the body part from the at least one transverse slice recording, wherein the digital three-dimensional model contains position data of the at least two reference markers, - determining surface data of the at least one partial slice wherein, during the determination of the surface data, the prosthesis is placed on the body part or on the real model and creating a digital three-dimensional surface model of the at least one subregion of the body part with the surface data, wherein the digital three-dimensional surface model is the part of the body part or a real model of the at least one subsection of the body part Surface model contains position data of at least two reference markers, - Merge ...
