Tomography applied to impaction of maxillary permanent teeth with anomalies in position was investigated in this study. In diagnosis and treatment planning in clinical orthodontics, it is important to establish the accurate spatial relationship between the embedding and other teeth in dentition, and the form of the involved teeth. The computed tomography was one case, and the three dimentional images of impacted teeth were reconstructed with the superimposed tracings. No root resorption was observed, and one tooth was curved with the other normal in shape in the same dentigerous cyst. Surgical fenestration of cyst allowed the impacted teeth to erupt spontaneously, after which the orthodontic treatment was performed. Multi-directional tomography was made of another case, in both the sagittal and horizontal directions. There was no evidence of root resorption or anomalies in morphology with the impacted or neighboring teeth, but one tooth position was inverted. The present study demonstrates that computed tomography and multi-directional tomography were useful in the orthodontic diagnosis and treatment planning of cases with impacted teeth.
