Planning for partial denture restoration or adjustment

摘要

The present invention is a method for computer-based planning of denture restoration or adjustment by the following method steps: a first digital 3D jaw model in which a partial denture is placed on the jaw is a denture reference model (M1). ), Generating a second digital 3D jaw model without partial denture as a jaw model (M2), determining the positional relationship of the denture reference model (M1) with respect to the jaw model (M2), position Generating a digital denture model (P) by subtracting the jaw model (M2) from the denture reference model (M2) while taking into account the relationship, automatically holding and / or supporting elements (3) in the denture model (P) Identification and / or identification by the user, the insertion axis (4 of the partial denture based on the denture model (P) Calculating the partial denture (P) holding and / or undercut depth of the support element (3) resulting from the insertion axis (4), the insertion axis (4 in the presentation of the jaw model (M2) ) And undercut depth.
