A Case of Cleidocranial Dysostosis with Multiple Impacted Supernumerary Teeth -Clinical application of three-dimensional computed tomography-

Abstract

Three dimensional imaging has been used with ease due to the spread of three-dimensional computed tomography (3 D-CT). It was difficult to image three dimensional constructions using conventional X-rays, but,3 D-CT has made it possible to observe the entire display in detail on a plane. As a result,3 D-CT is useful for the preoperative diagnosing and planning in the oral and maxillofacial region. We report that 3 D-CT was useful for extraction of multiple impacted supernumerary teeth in a patient with cleidocranial dysostosis.
The patient was a 12-year-old boy who had undergone dental treatment in our hospital since he was 3 years old. We diagnosed that it was necessary to extract multiple impacted supernumerary teeth, and therefore, we applied 3 D-CT clinically.
Using this method, we were easily able to observe the three dimensional position and shape of the impacted teeth.
