2019 Annual Session Conference

Genetics and Facial Growth Predictions

May 7, 2019 8:35am ‐ May 7, 2019 9:05am


Growth predictions for orthodontic and surgical treatment planning are typically based on a patient’s past and current growth patterns, as well as the facial growth trends observed within the patient’s biological family. While there is clear evidence that genetic variation can influence facial growth, our current understanding of which genes and gene variations best predict growth is limited. This session will focus on current research which suggests that genes involved in the pubertal growth spurt may provide valuable insights into how genetic information could improve future growth predictions. In addition, there will be discussion on the challenges we face when interpreting the role of genetics on jaw growth in conjunction with growth modification devices.

Learning Objectives:

  • Discuss the basis of patient-specific growth predictions (i.e., Will the incorporation of patient-specific genetic information provide us with more precise facial growth estimates in the future?).
  • Describe how genetic variation within key genes of the pubertal growth spurt may contribute to differences in facial shape and size that are observed clinically.
  • Recognize where we stand in the field of Orthodontics in terms of applying genetic findings to personalized clinical care and outcomes.
