Abstract
A method for registering a 3D mesh and a 3D volume image of a patients teeth obtains a 3D volume image of the patients 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.
Claims15
A method for registering a 3D mesh and a 3D volume image of a patient's teeth comprising:
- a) obtaining a 3D volume image of the patient's teeth in an occlusion position, the 3D volume image containing at least one jaw portion;
- b) generating contour surface content corresponding to at least one of lingual and vestibular surfaces of the teeth from the 3D volume image;
- c) providing a registered 3D mesh in an occlusion position, the registered mesh comprising at least a portion of a maxillary jaw and a mandibulary jaw, each of the jaws comprising at least one of the vestibular and lingual surfaces;
- d) registering the registered 3D mesh with the generated contour surface content.
A method for registering a 3D mesh and a 3D volume image of a patient's teeth further comprising at least one of displaying , storing, transmitting the registered 3D mesh with the 3D volume image.
The method of any of preceding claims further comprising segmenting the mandibular jaw or the maxillary jaw of the 3D volume image based on registration step d).
The method according to any of the preceding claims, further comprising the step of defining a first set of continuous curves corresponding to tooth position on the 3D volume image.
