AS17B27A - Can We Improve Atrophic Ridge with Surgically-Assisted Tooth Movement?

Apr 23, 2017 1:15pm ‐ Apr 23, 2017 1:45pm


It is a challenge for orthodontists to move the teeth efficiently into the atrophic alveolar ridge accompanied by periodontal improvement, especially in adult patients. In order to overcome this clinical limitation, adjunctive surgical procedures targeting the atrophic alveolar bone like cortical activation, ridge splitting, and ridge augmentation have been developed. When surgical stress reaches the periodontal tissues, active wound healing process is evoked to induce regional acceleratory phenomenon favorable for subsequent tooth movement. Based on understanding the healing mechanism of different type of surgical procedures, we orthodontists should control the surgically-assisted tooth movement in a timely manner. This lecture will suggest to you a clinical pearl of how to maximize the effect of surgically-assisted orthodontics, aiming at our patients’ healing of life with healing of periodontium.

Learning Objectives:

  • Identify the effect and the limitation of surgically-assisted tooth movement into atrophic alveolar ridge.
  • Recognize the significance wound healing process in relation to efficient tooth movement accompanied by tissue regeneration on the atrophic ridge.
  • Perform surgically-assisted tooth movement efficiently according to different type of surgical procedures.
