The use of cross-sectional spiral tomography in the placement of implants

Spiral tomography has been in use at the School of Dentistry, University of Otago, for 3 years. During this time over 140 examinations for radiographic workup prior to installation of implants have been undertaken. The cross-sectional spiral modality has proved to be of particular value for accurate assessment of bone. Its technical capabilities offer higher image quality compared with linear tomographic or computerised tomographic images. Imaging can be completed in one session, with minimal inconvenience to the patient and minimal radiation dose. High-quality images provide accurate information, contributing significantly to the long-term success of osseointegrated implants.
