Three-dimensional Evaluation of the Root Resorption of Maxillary Incisors in Pre-orthognathic Surgery Orthodontic Treatment

Root resorption in orthodontic treatment is an incidental condition associated with tooth movement, and maxillary anterior teeth are known to be the preferred site.Although the number of studies assessing root resorption in terms of volume has increased in recent years, few studies have assessed its relationship with three-dimensional tooth movement.The purpose of this study was to quantitatively evaluate the amount of root resorption in maxillary central incisors in preorthognathic surgery by measuring volume.In addition, the relationship between three-dimensional tooth movement and root resorption was investigated.The
