Abstract:
1. A computer implemented method comprising the steps of: determining a first tooth flat at a representation of a first patient's tooth; evaluating, using a computer processor, the first tooth flat to provide characteristic data representing at least one geometric characteristic of the first tooth flat; using the characteristic data, stored in a non-transitory computer readable storage medium operably coupled to a computer processor, to calculate a computer model of the patient's possible jaw motion under occlusal contact between teeth in the patient's upper and lower jaws; determining a motion path representing a model of a possible movement of the jaws relative to one another under the occlusal contact, wherein the motion path extends along a line between a first and a different second positional relationship of the jaws; obtaining a preliminary representation of a dental restoration, wherein the preliminary representation is initially oversized such that the preliminary representation overlaps with one or more opposing teeth under the occlusal contact along the motion path; and using the motion path for determining a shape of at least part of the dental restoration by virtually moving at least a partial representation of a tooth opposite of the dental restoration on the motion path to virtually trim the preliminary representation in order to remove the overlap.
