Relationship between orthodontic treatment and root resorption

Abstract

As one of the common complications of orthodontic treatment, external apical root resorption (EARR) often occurs during orthodontic treatment. This paper systematically elaborates the degree classification of EARR and the biological mechanism of root resorption in orthodontic treatment. At the same time, orthodontic root resorption is caused by a variety of factors. They are not only affected by genetic and environmental factors, but also by great individual differences. This paper summarizes the factors influencing the root resorption of orthodontic teeth and the prognosis of root resorption. This paper also provides some suggestions for the prevention and treatment of root resorption in the process of orthodontics, in order to provide guidance and help for the clinical work of orthodontists.
