Ankylosis or ankylosis-like eruption distrubances not only hinder orthodontic tooth movement but also causes serious vertical bone defect during growth. The vertical discrepancy necessitates creative tooth movement with or without extraction of the ankylosed tooth. This course deals with transverse, vertical total arch movement as well as major root movement for the restoration of bone defect. Depending on the site of bone defect, differential approaches based on sound understanding on suture biology and orthodontic biomechanics would apply. At the end of the course, participants would obtain the biomechanical background and clinical evidences for challegning type of tooth movement.
Learning Objectives:
After this lecture, attendees will be able to:
Comprehend the rationale of major transverse correction for the restoration of bone defect in the anterior region.
Understand the biomechanical background of total arch intrusion for the restoration of bone defect in the anterior region.
Understand the biomechanical background of major root movement for the restoration of bone defect in the posterior region.
