Radiographic examination is essential in diagnosis and treatment planning in dentistry. The interpretation of an image can be confounded by the anatomy of both the teeth and surrounding structures. The ability to assess an area of interest in 3-Dimension is beneficial for both novice and experienced clinicians.
Cone Beam Volumetric Tomography also known as cone beam computed tomography, captures a cylindrical volume of data in one acquisition. The volume acquired by a CBVT is composed of voxels. A voxel is a 3-D pixel. As the data are captured in a volume, all the voxels are isotropic, which enables objects within the volume to be accurately measured in different directions. CBVT offers distinct advantages over conventional CT. These advantages include increased accuracy, higher resolution, scan-time reduction, and dose reduction.
CBVT allows the clinician to view the tooth and pulpal structures in thin slices in all three anatomic planes: axial, sagittal, and coronal. This capability alone allows visualization of periapical pathology and root morphology previously impossible.
This presentation will be containing its use for assessment of implants, for third molar extraction and orthodontic analysis. Along with its use in endodontics for Apical morphology and suspected lesions of endodontic origin, Root canal system morphology, Presurgical visualization, Suspected root fractures and trauma, Internal and external root resorption.
