Description

A basic understanding of patients’ growth and development is an integral and important part of every orthodontist’s education. Such knowledge is important because the practice of evidence-based orthodontics is predicated on the ability of the clinician to apply such information when developing treatment objectives and evaluating post-treatment outcomes. To date, most orthodontists have received little guidance on how to apply the didactic information they learned in classroom settings to individual patients. To make meaningful pretreatment diagnostics, orthodontists must be able to adjust for their patient’s somatic growth and maturation. Dental maturation is particularly important for determining when a patient’s premolars and canines might be expected to emerge. To develop treatment objectives, orthodontists need to know their patient’s future growth potential and be able to adjust based on the sex, age, and growth pattern of the patient. Expected growth changes are also important when evaluating a patient’s post-treatment changes. In order to determine the modification necessary to make future treatments more effective or efficient, orthodontists must be able to separate each patient’s treatment changes from his/her growth changes.

LEARNING OBJECTIVES

  • Know how to make individualized adjustments to available reference data for a patient’s body size and skeletal maturation. 
  • Be able to estimate a patient’s dental maturation and approximate age of dental eruption. 
  • Be able to estimate maxillary and mandibular growth changes, and the amounts of dental eruption, that would be expected to occur during the treatment of any given patient, as well as the adjustments necessary for their sex, age, and growth patterns. 
  • Be able to distinguish between patients with favorable and unfavorable growth potential. Be able to estimate whether the changes that occurred in a given patient were due to treatment and/or growth.

Contributors

  • DR. PETER BUSCHANG

    Dr. Buschang is regents professor and director of orthodontic research at Texas A&M University Baylor College of Dentistry. Previously, he was a National Institute of Dental and Craniofacial Research postdoctoral fellow in the Department of Orthodontics at the University of Connecticut Health Science Center and then a FRSQ scholar in the Orthodontic section and Human Growth Research Center at the University of Montreal. His research interests focus on craniofacial growth, developmental adaptations to orthodontic and surgical treatments, and oral-motor function. He has published over 270 peer-reviewed articles, three books and numerous book chapters. Dr. Buschang has given over 120 invited lectures and workshops and has served as associate editor for several journals. He is the only person to hold honorary memberships in both the American Association of Orthodontics and the Edward H. Angle Society. In 2011, his former residents honored him by establishing the Peter H. Buschang Endowed Professorship in Orthodontics.
