[Clinical application of computer assisted technology based spiral CT scan for locating impacted tooth].
OBJECTIVE
To evaluate clinical value of computer assisted technology for locating the impacted tooth.


METHODS
Thirty-five patients with impacted tooth were received spiral CT scan. The DICOM data were processed by Simplant software for locating the impacted tooth.


RESULTS
The reconstruction images clearly showed detail of the impacted teeth, including 3D surface image, eruption orientation, buccal and lingual location, medial and distal location and relationship with dentition and circumambient anatomic structure.


CONCLUSIONS
The computer assisted technology can localize the impacted tooth precisely and provide valuable information for clinical treatment.
