Abstract

A method and apparatus are disclosed enabling an orthodontist or a user to create an unified three dimensional virtual craniofacial and dentition model of actual, as-is static and functional anatomy of a patient, from data representing facial bone structure; upper jaw and lower jaw; facial soft tissue; teeth including crowns and roots; information of the position of the roots relative to each other; and relative to the facial bone structure of the patient; obtained by scanning as-is anatomy of craniofacial and dentition structures of the patient with a volume scanning device; and data representing three dimensional virtual models of the patient's upper and lower gingiva, obtained from scanning the patient's upper and lower gingiva either (a) with a volume scanning device, or (a) with a surface scanning device. Such craniofacial and dentition models of the patient can be used in optimally planning treatment of a patient.

Claims (89)

(c) identifying said tooth-roots abnormalities from said three dimensional virtual model; and

(d) planning corrective treatment steps to cure said tooth-roots abnormalities.

2. The method of claim 1 , wherein said tooth-roots abnormalities comprise one or more tooth-roots entangled with one or more different tooth-roots; and wherein said corrective treatment steps comprise repositioning said teeth in a step-wise manner such that said treatment steps enable un-entangling of said tooth-roots.

3. The method of claim 1 , wherein said tooth-roots abnormalities comprise one or more tooth-roots or portion(s) thereof placed out-side of said upper or lower jaw bones of said patient as applicable; and wherein said corrective treatment steps comprise repositioning said teeth, in a step-wise manner, such that said tooth-roots are completely contained in such bones as desired.

4. The method of claim 1 , wherein upper and lower gingiva are integrated within said three dimensional virtual model of craniofacial and dentition structure of said patient; and wherein shape of said upper and lower gingiva is adjusted as desired thereby enabling curing said tooth-roots abnormalities.

5. The method of claim 1 , wherein orthodontic appliances are designed for assisting in curing said tooth-roots abnormalities.

6. The method of claim 5 , wherein said orthodontic appliances include one or more orthodontic brackets.

7. The method of claim 5 , wherein said orthodontic appliances include one or more sets of aligners.

13. The method of claim 9 , wherein said tooth-appearance abnormalities comprise one or more teeth of said patient having undesirable sizes and shapes; and wherein said corrective treatment steps are to resize and reshape each of said one or more teeth to said desired size and shape.

14. The method of claim 9 , wherein said tooth-appearance abnormalities comprise one or more teeth of said patient having one or more line angles misplaced on said one or more teeth; and wherein said corrective treatment steps are to properly restore each of said one or more of line angles.

15. The method of claim 9 , wherein said tooth-appearance abnormalities comprise one or more teeth of said patient having one or more points misplaced on said one or more teeth; and wherein said corrective treatment steps are to properly place each of said one or more misplaced points.

16. The method of claim 9 , wherein tooth anatomy, size and form can be restored based upon a template tooth from a library of said template teeth.
