Planning a repair or adaptation of a dental partial denture

摘要

The invention relates to a method for computer-aided planning of a repair or adaptation of a dental partial denture with the method steps: generating a first digital 3D model of a jaw with the partial denture positioned on the jaw as a prosthesis reference model (M1), generating a second digital 3D model of the jaw without the partial denture as a jaw model (M2), determining a positional relationship of the prosthetic reference model (M1) to the jaw model (M2), generating a digital prosthesis model (P) by subtracting the jaw model (M2) from the prosthetic reference model (M2) taking into account the positional relationship, automatic and / or or identifying by a user identification of holding and / or supporting elements (3) in the prosthesis model (P), calculating an insertion axis (4) of the partial prosthesis based on the prosthesis model (P), calculating from the insertion axis (4) resulting undercut depths of the holding and / or supporting elements (3) in the prosthesis model (P) , Displaying the insertion axis (4) and the undercut depths within the representation of the jaw model (M2).
