Abstract
BackgroundRadiographs are integral in evaluating implant space and inter-root distance. The purpose of this report is to introduce a method for evaluating the 3D root position with minimal radiation using a 3D tooth model composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root.Materials and methodsIntraoral scan and CBCT scan of the patient were obtained before treatment. In the CBCT image, tooth segmentation was performed by isolating individual teeth from the maxillary and mandibular alveolar bone using software program. The 3D tooth model was fabricated by combining segmented individual teeth with the intraoral scan.ResultsA post-treatment intraoral scan was integrated into the tooth model, and the resulting position of the root could be predicted without additional radiographs. It is possible to monitor the root position after a pretreatment CBCT scan using a 3D tooth model without additional radiographs.ConclusionThe application of the 3D tooth model benefits the patient by reducing repeated radiation exposure while providing the clinician with a precise treatment evaluation to monitor tooth movement.

Summary
The purpose of this report is to introduce a method for evaluating the 3D root position with minimal radiation using a 3D tooth model composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root. Clinicians need to perform cone-beam computed tomography (CBCT) scanning to monitor and evaluate tooth movement, especially root movement. The purpose of this report was to suggest a 3D method to monitor tooth position without additional CBCT scans. The method uses 3D tooth models composed of an intraoral-scanned crown and a CBCT-scanned root. By combining isolated individual teeth and intraoral scans, tooth models composed of intraoral-scanned crowns and CBCT-scanned roots were fabricated. Additional intraoral scans at any stage of treatment were integrated into the tooth models, and the resulting
