Abstract
(EN)
A method for registering a 3D mesh and a 3D volume image of a patient's teeth obtains a 3D volume image of the patient's teeth in an occlusion position, the 3D volume image containing at least one jaw portion. A contour surface is generated to form the 3D mesh corresponding to at least one of lingual and vestibular surfaces of the teeth from the 3D volume image. A registered mesh is provided in an occlusion position, the registered mesh having at least one of the vestibular and lingual surfaces. The registered mesh is registered with the generated contour surface content and displayed with the 3D volume image.
