The Magill Sagittal and Drive Tube was developed as a result of the demands for more efficient "fixed" functional appliances. Continued pressure on orthodontic laboratories and manufacturers has resulted in the development of various 'fixed' versions of the appliances necessary to accomplish the goals of functional jaw orthopedic therapy. The introduction of 'fixed' functional treatment modalities into the traditional "braces correct everything" USA market has spread rapidly over the past fifteen years. This method has evolved due to the demand by practitioners who want to gain more total control over the patient's treatment.

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.
