Abstract
A method to bite set a dental model includes: scanning upper and lower arches of the dental model; scanning the upper and lower arches in their bite position; and aligning the upper and lower arches.
Claims16
A method to bite set a dental model, comprising:
- scanning upper and lower arches of the dental model;
- scanning the upper and lower arches in their bite position;
- and
- aligning the upper and lower arches to bite set the dental model, wherein the bite setting uses geometry matching, further comprising:
- selecting a predetermined number of points on the jaw model;
- removing noisy points;
- computing closest points on the jaw component;
- and
- computing a transformation that matches two points, one from each jaw model.
