Abstract:
Objective:To evaluate the feasibility of the 3-D surface reconstruction by multislice spiral CT(MSCT) technique in the diagnosis of impacted teeth in maxilla.Methods:Eighty two cases with impacted teeth in maxilla were examined with volumetric CT scan using MSCT,the dental reconstruction images were obtained with multiplanar reformation technique and 3D-reconstruction technique.Results:Dental surface 3D-reconstruction image could display the shape,location and eruption orientation of the impacted teeth clearly.Conclusion:3-D surface reconstruction by MSCT can provide valuable diagnostic and anatomic information of the impacted teeth in maxilla.
