영문 초록

A successful orthodontic treatment depends not only on the initial diagnosis but also on accurate assessment of treatment progress including monitoring and evaluating the tooth movement, especially, root movement. As cone-beam computerized tomography (CBCT) can depict the true root position and angulation in 3-dimensions, accurate evaluation is possible. However, it is challenging for clinicians to repeatedly take CBCT scans because of the patients’ or their parents’ concern on radiation hazard. This report introduces a new method for monitoring of 3D tooth movement without additional CBCT scans during orthodontic treatment. This method is using an Individual Composite Tooth Model composed of an intraoral-scanned crown and CBCT-scanned root. The tooth model was fabricated by combining the images of the isolated individual tooth and intraoral scan. When evaluation of the root position is needed during treatment, additional intraoral scan at any stage of treatment can be integrated into the tooth model and its resulting position of the root can be estimated without the need of additional CBCT scan. With this tooth model, clinicians will be able to estimate 3D tooth movement during orthodontic treatment only with additional intraoral scans.
