Summary
Introduktion: This study was undertaken to determine the usefulness of transverse spiral tomography with the Cranex-Tome apparatus in diseases of the temporomandibular joint and in implantology.
Material and methodes: The temporomandibular joint was studied in 35 patients. Pathologic bony structures, osteophytes, and abnormalities of the joint space were found in 34 patients. A malignant tumor was detected in one patient. In the case of the temporomandibular joint, spiral pantomography appears to offer superior results to conventional radiography by filtering out all structures superimposing on the joint. In addition, 14 patients qualified to receive 60 endosseous implants were studied. Pantomographs of the maxilla and mandible, as well as tomographs were used to measure the height and width of the alveolar process prior to selection of the implant. The precision of imaging of structures important to the implantologist was assessed.
Results: Transverse spiral radiographs of the alveolar process gave a clear view of the mandibular canal, mental foramen, and fundus of the maxillary sinus. Measurements of the height and width of the alveolar process appearing on transverse spiral radiographs created a precise basis for the selection of an implant with the right length and diameter.

K e y w o r d s: temporomandibular joint – implantology – Cranex–Tome apparatus – transverse spiral tomography.
