Abstract
A method and system for (semi-) automatic dental implant planning (A) is described including (a) means for creating 3D models of a tooth setup (b) and/or means for creating 3D models of parts of the jaw, (c) means for detecting zones in the jaw where implants can (or optionally cannot be placed), (d) means for detecting restorative elements in the tooth setup, (e) means for determining candidate implant dimensions, positions, orientations and configurations, (f) means for obtaining implant plans, (g) means for comparing implant plans to each other or to given criteria, (h) means for selecting or improving an implant plan.
Claims15
A method for preparing information for automated or semi-automated dental implant planning from image information relating to the jaw of a patient, comprising:
- (a) generating 3D models of parts of the jaw bone, and
- (b1) detecting anatomical and artificial elements in the 3D model of the jaw bone based on image analysis, and
- (b2) automatically selecting zones in the 3D model of the jaw bone where implants can or cannot be placed, wherein the step of generating 3D models of parts of the jaw comprises the steps of:
- slicing the 3D model of the jaw into a number of 2D slice images,
- generating a panoramic curve for each of the 2D slice images,
- evaluating in each slice image if one or more 2D features are present along the panoramic curve, and
- combining the information of multiple slices to confirm the presence of a tooth.
