Abstract:
OBJECTIVETo study the allocation of embedded teeth in jaws using the three-dimensional reconstruction technique of 64-slices spiral CT.
METHODS27 cases were examined by helical scanning of axial view volume scan CT. The exact localization of the embedded teeth in jaws was acquired by using volume rendering (VR), maximum intensity projection (MIP), multiplanar reformation (MPR) and curve plane reconstruction (CPR).
RESULTSThe localization, morphous, size, erupted orientation and relationship between surrounding tissues of the 41 embedded teeth in 27 patients were displayed by effectually using the images of VR, MIP, MPR and CPR. The election of orthodontic treatment or surgical intervention was decided by using 64-slices spiral CT.
CONCLUSIONThe exact data and objective evidence of the treatment plan could be provided by 64-slices spiral CT which will have important clinical application.
