[Control of treatment and facial balance]

Cephalometric analysis (made from the tracings of lateral head X-rays) participates to the orthodontic diagnosis. As it is done for each patient before and after treatment, the analysis allows for precision of the goals and for the control of their obtainance. Because therapeutic means have grown more and more precise, progress tracings during the active treatment are now considered very precious. They display teeth (and bones) good and bad displacement. They allow for mechanical activations, therapeutic decisions, and help for a better precision of the patient's cooperation. As the stability of the treated occlusion is the main goal, may be the post-treatment records (taken immediately after debanding) could be delayed for some months or even some years.
