Abstract: Digital design and/or fabrication of a dental prosthesis that includes a gingiva part having retention pockets and corresponding injection channels that extend from the retention pockets to an exterior of the gingiva part. The positioning of a matrix mated to a ball attachment of a dental implant is fixed in the retention pocket by injection of a curable adhesive through the injection channels and into the retention pockets. The location of the retention pockets and the injection channels may be automatically generated by a computer-aided design/computer-assisted manufacturing (CAD/CAM) system. The gingiva part including the retention pockets and injection channels can further be designed and fabricated by the CAD/CAM system.

Abstract: A method for the computer-aided editing of a digital 3D model (1) of a dental object using digital tools (T1, T2, T3) provides for the identification of different dental-specific regions (R1, R2, R3) of the 3D model (1) that are affected by the tool (T1, T2, T3) in different ways, for computation of the effect on the whole 3D model and for display thereof as a proposal model (2) together with the 3D model (1). The proposal model (2) is then rejected or accepted in part or in full. If it is accepted in part, at least one subregion of the 3D model (1) is selected as a region (10) and a result model (6) is formed from the 3D model (1) and the proposal model (2) by virtue of the 3D model (1) being taken as the starting point for replacing the selected region (10) or at least a central portion of the selected region (10) with a corresponding region of the proposal model (2) or approaching the latter using a strength factor (S).
