Application of cone-beam computed tomography in the treatment of impacted maxillary teeth.

PURPOSE :To investigate the treatment of impacted maxillary teeth with localization via cone-beam comp tomography (CBCT). METHODS: Eleven cases with impacted maxillary teeth on X-ray examination were selected 2009 to 2010. The impacted maxillary teeth were scanned by CBCT.The three-dimensional images of impacted maxilla teeth were obtained by muhiplanar reconstructions (MPR) to determine the location of impacted teeth. RESULTS: C and MPR can demonstrate the morphology and location and growing state of the impacted maxillary teeth. CONCLUS CBCT and MPR are the most accurate and effective methods to localize the impacted maxillary teeth. [ABSTRACT FROM AUTHOR]
