[Three dimensional reconstruction of human permanent teeth].
OBJECTIVE
Dental anatomy is one of the most important basic courses in the education of stomatology. The deep understanding of morphologic characters is closely instructive to the clinic of endodontics, oral surgery, orthodontics and prosthodontics.


METHODS
In present study, 32 permanent teeth from a skull specimen were inputted into computer after the processes of burying, grinding, photographing, scanning and recognizing. By the techniques of reconstruction, the 3D stereo tooth models were retrieved from 2D digital data.


RESULTS
On the basis of those 3D data, computer graphics techniques were used to realize the lighted, smoothed and shaded teeth.


CONCLUSIONS
Such a series of data teeth might be applicated as a corner stone of the computer aided instruction (CAI) in stomatology.
