Appl. No.:

16/379907
Inventors:

- St. Paul MN, US
Eric S. Hansen - Arden Hills MN, US
Steven C. Demlow - Mendota Heights MN, US
Richard E. Raby - Lino Lakes MN, US
International Classification:

G06T 7/00
G06T 7/73
G06T 7/33
A61C 7/00
A61C 11/00
A61C 9/00
G06T 19/20
Abstract:

A method for determining virtual articulation from dental scans. The method includes receiving digital 3D models of a person's maxillary and mandibular arches, and digital 3D models of a plurality of different bite poses of the arches. The digital 3D models of the maxillary and mandibular arches are registered with the bite poses to generate transforms defining spatial relationships between the arches for the bite poses. Based upon the digital 3D models and transforms, the method computes a pure rotation axis representation for each bite pose of the mandibular arch with respect to the maxillary arch. The virtual articulation can be used in making restorations or for diagnostic purposes.
