An Analysis of Early Changes to the Craniofacial Skeleton Induced by Transpalatal Distraction in a Patient with Maxillary Constriction, Based on Computed Tomography Scans – Case Report

Following Surgically Assisted Rapid Palatal Expansion, Do Tooth-Borne or Bone-Borne Appliances Provide More Skeletal Expansion and Dental Expansion?

“…Many studies have used the TPD appliance or a similar appliance, such as the Uni-Smile Distractor (Titamed, Belgium) or the MWD device (Normed, Germany), with great results. 6,7 A tooth-borne (TB) appliance, the Hygienic Appliance for Rapid Expansion (Hyrax) was introduced by Dr. William Biederman in 1968. 8 Many studies have also shown great results with the Hyrax, 9,10 but skepticism remains, as studies evaluate its apparent dentoalveolar effects.…”
