METHOD AND SYSTEM FOR BITE REGISTRATION

摘要

The present invention relates to method and system for bite registration using multiple bite registrations. In this method or system, when both the 3D teeth model of the upper jaw and the 3D teeth model of the lower jaw are successfully aligned with the bite surface, the bite surface with the 3D teeth models of the upper jaw and the lower jaw is displayed for further evaluation; the bite surfaces selected by the user are combined to generate a final bite registration. Using multiple bite surfaces for registration improves the accuracy.

主权项

1. A method of bite registration, characterized by comprising the steps of:
a. generating 3-dimensional (3D) teeth models of the upper jaw and the lower jaw; b. acquiring a bite surface containing a portion of upper and lower jaws simultaneously; c. attempting to align the 3D teeth models of the upper jaw and the lower jaw with the bite surface; d. displaying the bite surface together with the 3D teeth models of the upper jaw and the lower jaw aligned with the bite surface if alignment is successful; e. repeating step b to step d so as to obtain at least two successful bite registrations corresponding to different displayed bite surfaces; f. selecting one or more successful bite registrations by evaluating at least two successful bite registrations; and g. computing a final bite registration using selected one or more successful bite registrations.
