Consideration of these factors is necessary for the rational prescribing of drugs in psychiatry and can prevent potentially dangerous drug interactions.

Past orthodontic research by Schwarze in "Expansion and Relapse in Long Follow-Up Studies" concluded "... that orthodontically induced transverse sizes of the dental arches are very unstable." The article further stated that, "the majority of patients showed a decrease of the transverse molar and canine distance from the end of treatment to the follow-up examination." Also emphasized was the fact that "prolonged retention periods do not prevent relapses." These findings are based on orthodontic techniques that focus on movement of teeth and maxillary expansion without regard for existing cranial base and cranial bone distortions.
