TMJ diagnosis and treatment in a multidisciplinary environment--a follow-up study.

New modalities--TMJ direct parasagittal CT and MRI scans and arthroscopic visualization and surgery--along with psychological and other health professional support, are changing the approach to clinical orthodontic practice. This report presents an update on clinical experience over a period of time, with emphasis on orthodontics, psychology, and arthroscopic surgery.

Corrected parasagittal direct CT imaging of the temporomandibular joint. With arthroscopic correlation.

Direct CT studies of the temporomandibular joints, using axial, coronal, and condylar axis corrections for parasagittal views perpendicular to the long axis of the condyle head to provide detailed CT examination of the bony structures and associated soft tissues. Images of selected patients are correlated with arthroscopic evaluation and treatment, yielding a unique perspective for evaluation of the imaging method and the joint itself. Based on these findings, a hypothetical mechanism of TMJ derangement is proposed.

Analysis of panoramic cephalometrics using s skeletal cephalostat.

A panoramic head positioning device, the S.C., was tested for magnification production of radiographs and for repositioning. Ten skeletal Class I dentulous skulls with uniform metal markers were examined. The purpose was to see if a skeletal analysis could be obtained from panoramic radiographs. Basal skeletal magnification varied anatomically both vertically and horizontally, but the magnification percentages and their ranges, for the most part, were calculable. The few exceptions were believed due to lack of proper alignment of the S.C. and the General Electric Panelipse. Proper alignment could also correct the right to left asymmetrical magnification differences. Means and standard errors from 290 skeletal measurements were calculated and could serve as standards for skeletal analysis using panoramic cephalometrics.
