Abstract:
1. A method for providing feedback data useful in at least one prosthodontic procedure associated with an intra oral cavity, comprising: (a) receiving, on a computer, scan data comprising at least one numerical entity representative of a three-dimensional surface geometry of at least part of the intra-oral cavity comprising a dental preparation and one or more teeth adjacent to the dental preparation; (b) manipulating, on a computer, the entity to provide desired data of a type useful in at least a first procedure comprising a selected mounting of a dental prosthesis with respect to the dental preparation, wherein the desired data comprises information regarding the geometry of at least a portion of the dental preparation; (c) determining, using a computer, at least one relationship between the desired data and the first procedure indicating that a geometry of the portion of the dental preparation compared to the prosthesis is unsuitable for the dental prosthesis mounting according to the first procedure, including determining that external surfaces of a virtual model of the dental prosthesis would interfere or collide with the one or more teeth adjacent to the dental preparation during an insertion of the dental prosthesis onto the dental preparation; and (d) generating, using a computer, feedback data based on the determination of act (c) and comprising one or more suggested changes to the dental preparation to enable mounting of the dental prosthesis to the dental preparation without interference between external surfaces of the dental prosthesis and the one or more teeth adjacent to the dental preparation.
