Abstract：Objective To observe the clinical application of cone beam computed tomography(CBCT)in impacted maxillary anterior teeth(IMATs).Methods Twenty-eight patients(30 teeth)with IMATs underwent curved surface tomography and CBCT.The positioning of IMATs was compared between them.Results Of 30 IMATs,28 received orthodontic traction,with treatment failure in 1 and success rate of 96.4％,and 2 were extracted due to inverted position.Compared with curved surface tomography,diagnostic rate of IMATs in the labial dental arch,mild root curvature and open apices was higher,while that of IMATs in the dental arch was lower using CBCT(P＜0.05).Conclusion CBCT can accurately display the position of IMATs and guide the orthodontic procedure.
