TMD warning sign: cephalometrics.

The significance of predisposing factors to TMD is quite evident when considering the prevalence of orthodontic relapse and with the occurrence of TMD related symptoms observed in previously treated orthodontic patients. In using the Modified Sassouni Plus Cephalometric Analysis, the clinician now possesses an invaluable tool that is readily available without adding to the examination expense. The invaluable information gained from cephalometric evaluation should not, however, be used to replace other diagnostic TMJ radiographs. If a joint problem is suspected, one should follow the normal protocol for the examination of the temporomandibular joints.
