Non-surgical Maxillary Expansion in Adults: Facts and Fallacies

May 7, 2019 8:00am ‐ May 7, 2019 8:30am


Balanced transverse relationship between maxillary and mandibular dentition is a prerequisite for establishment of normal occlusion regardless of patients age. Mini-implant assisted rapid palatal expansion has been recently introduced as a non-surgical alternate for obtaining transverse maxillary expansion in post pubertal patients. There are several modifications of the device and one such modification is the Maxillary skeletal expander which is supposed to bring about orthopaedic changes in the midface with minimal repercussions on the dentition and periodontium. The efficacy of this device in eliciting changes in the maxilla, mid-face and dentition and its influence on airway dynamics will be discussed in this presentation with illustrative cases.

Learning Objectives:

  • Recognize the biological basis and rationale for non-surgical maxillary expansion in adults with maxillary transverse discrepancy.
  • Diagnose and manage maxillary transverse discrepancy with a hybrid mini implant supported maxillary expander.
  • Appreciate the effects and limitations of the approach on the maxilla, dentition, mid-face and airway dynamics.
