Claim Text:
1. A method for displaying at least one property of an optically determined surface geometry of a tooth on a computer screen, the method comprising the steps of: repeatedly scanning the tooth using a stereometry camera, checking the surface geometry of the tooth, and determining whether one of plural defined criteria is satisfied for each voxel of the surface geometry of the tooth, each voxel being a volume pixel representing a smallest unit within a computational three-dimensional volume, said checking including updating of optically determined data of each voxel, wherein at least a first of the defined criteria is a first sum of the updatings of the optically determined data of each specific voxel, and a second of the defined criteria is a second sum of the updatings of the optically determined data of each specific voxel; assigning at least a first property to voxels satisfying the first criteria, and assigning a second property to voxels satisfying the second criteria, to thereby define all of the voxels are divided into respective sets with a first set of voxels that each satisfy the first criteria and a second set of voxels that each satisfy the second set of criteria; and graphically displaying the surface geometry on the tooth on the computer screen, with at least the voxels of the first set assigned with the first property being graphically displayed differently from the voxels of the second set assigned with the second property.
