Case History:
Patient presented with a complaint of pain around tooth #17. Clinical diagnosis was pericoronitis. When panoramic x-ray revealed a close association between the apices of #17 and the mandibular canal (see Sedaghatfar M, August MA, Dodson TB. Panoramic radiographic findings as predictors of inferior alveolar nerve exposure following third molar extraction. J Oral Maxillofacial Surg. 2005 Jan;63(1):3-7), the oral surgeon ordered a CT scan. From the CT it appeared that the mandibular canal passed between the roots of #17. The 3D reconstruction clearly shows this to be the case.

Photo Description:
Cross-sections, a panoramic and 3D reconstruction of the area around tooth #17 are presented.

Clinical Benefit:
The patient can now give truly informed consent on whether she wants to risk removing #17, whether to try to pursue a form of periodontal surgery, whether to undergo a coronectomy or whether to “wait and see.”

Photo Description:
Patient is a 60 year old interested in a lower fixed denture. Both implants in the picture were associated with an abscess and one of them was mobile. Regular x_rays showed proximity to the IAN to get a better view of the area before attempting removal the patient was referred to IVI (Orl) to get a CT. With the help of the scan and Osseoview the clinician was able to safely determine the true correlation of the Implants to the abscess.

Photo Description:
This patient was imaged to assess the symmetry of projection of his malar processes (cheekbones) following surgical repair. The use of cone beam technology allowed the clinician to assess the symmetry of the correction and the maturation of the healing process in the presence of the titanium fixation plates without the scatter due to the presence of the plate as seen in conventional CT imaging. The clinician also gained information from the straight on view of the skull and the head back position.
