DETERMINATION OF THE POSITION OF THE CONDYLAR ARTICULATION AXIS FOR CREATING A VIRTUAL ARTICULATOR

摘要

A method is proposed for creating a virtual articulator for a jaw and the associated dentition having the following steps:
image a virtual model of the teeth of the maxilla (140);image a virtual model of the teeth of the mandible (130);buccal imaging of the position and orientation of the teeth (130, 140) of the maxilla and mandible in the closed-bite position;buccal imaging of the position and orientation of the teeth (130, 140) of the maxilla and mandible in a slightly open position;computational determination of the position of the condylar articulation axis (150) relative to the teeth (130, 140) of the mandible and/or maxilla from the imaged positions and orientations; and

a virtual articulator can thereby be created without having to possess special knowledge, e.g. of the dimensions of a specific mechanical articulator or any adapter elements, or their arrangement.

1. A method for determining the position of the condylar articulation axis of a jaw relative to the teeth of the mandible and/or maxilla, the method comprising
buccal imaging of the position and orientation of the teeth of the maxilla and mandible in the closed-bite position; buccal imaging of the position and orientation of the teeth of the maxilla and mandible in a position in which the mandible or maxilla is rotated relative to the closed-bite position by an angle of 1-20° about the condylar articulation axis; and computational determination of the position of the condylar articulation axis relative to the teeth of the mandible and/or maxilla from the imaged positions and orientations.
