Abstract
Orthodontists need to understand the orthodontic risks associated with systemic disorders. Axenfeld-Rieger syndrome (ARS) is a rare autosomal dominant disorder with genetic and morphological variability. The risks of orthodontic treatment in ARS patients have been unclear. Here we describe the correction of an anterior open bite in a 15-year-old Japanese female ARS patient by molar intrusion using sectional archwires with miniscrew implants. An undesirable development of external apical root resorption (EARR) was observed in all intrusive force-applied posterior teeth during the patient’s orthodontic treatment, suggesting that ARS patients have a higher risk of EARR than the general population.
