Technical note. Sagittal tomography as an adjunct to cross-sectional evaluation of select implant sites.

OBJECTIVE To supplement conventional cross-sectional tomography with a sagittal projection in order to verify the location of vital anatomical structures prior to dental implant surgery. METHODS A method is described that illustrates the theory, technique and benefits of incorporating sagittal tomography into the radiographic examination of a dental implant patient. RESULTS Local variations in the inferior-superior position of the mandibular canal or encroachment of the sinus on areas immediately adjacent to the proposed maxillary implant site can be demonstrated. CONCLUSIONS The additional information gained from sagittal tomography aids the clinician in appreciating the orientation and morphology of the anatomical area under examination.
