AS17B50B - The Use of TSADs in Orthopedic Sutural Separation


Apr 25, 2017 9:15am ‐ Apr 25, 2017 9:35am


Description

The use of temporary skeletal anchorage devices (TADs) to aid in sutural separation is a promising new concept in clinical orthodontics. In this lecture, preliminary data on sutural deformation induced by TAD-supported and dental-borne devices will be presented. Specifically, we will discuss loading of the zygomatico-maxillary suture induced by bone-anchored maxillary protraction compared to traditional reverse pull headgear treatment, and deformation of midpalatal suture in TAD-supported compared to dental-borne expander. Additionally, preliminary data on bone formation and osteoblast differentiation at the zygomatico-maxillary suture during bone anchored maxillary protraction devices will be presented and discussed.

Learning Objectives:

  • Recognize the deformation of zygomaticomaxillary and midpalatal suture induced by dental-borne devices.
  • Recognize the deformation of zygomaticomaxillary and midpalatal suture induced by skeletally-borne devices.
  • Identify the difference in sutural loading between the dental- and skeletal-borne devices.
