This article has been written as a rebuttal to the conclusions drawn by Dr. Marvin Hanson in his article, "Tooth Movement Associated with Oral Myofunctional Therapy: A Clinician's Report" which appeared in the November, 1992 issue of the International Journal of Orofacial Myology. This rebuttal relates to the broader implications of all tooth movement which Dr. Hanson's title implies, and includes the specific reference to overjet reduction which the abstract of Dr. Hanson's article informs us is the focus of his clinical observation and measurement.
