Augmented Reality Dentistry

This study aims to evaluate the accuracy of augmented reality (AR)-assisted dental procedures. Patient-specific anatomical data will be acquired using cone-beam computed tomography (CBCT) and intraoral scanning and integrated to create a three-dimensional virtual model for treatment planning. Different dental procedures, including tooth extractions, dental implant placement, and orthodontic procedures, will be virtually planned before treatment. During the clinical procedure, the planned anatomical and procedural information will be visualized through an AR system, providing real-time guidance to the operator. The accuracy of AR-assisted treatment will be assessed by comparing the preoperative virtual plan with the postoperative clinical outcome, evaluating deviations between planned and achieved results.

Effects of Three Orthodontic Archwire Protocols on Root and Bone Changes

This randomized controlled clinical trial compares the effects of three orthodontic archwire protocols used during the alignment phase on anterior tooth roots and the supporting alveolar bone. Participants were randomly allocated to one of three parallel groups according to the experimental archwire used. Cone-beam computed tomography (CBCT) images were obtained before treatment initiation and after completion of the follow-up period. The primary outcome is volumetric root resorption, while secondary outcomes include changes in Buccal alveolar bone height and thickness. Recruitment and follow-up have been completed, and the study is currently in the data verification and statistical analysis phase. The findings are expected to help clinicians choose archwire protocols that reduce undesirable biological side effects during orthodontic treatment.

3-D Evaluation of Alveolar Bone Changes and Root Resorption After Traction of Buccally Displaced Maxillary Canines

This clinical study used CBCT images to investigate the alveolar bone changes and root resorption in unilateral buccally displaced maxillary canines and adjacent teeth before and after orthodontic traction of unilateral BDMCs. The CBCT images will also be used to compare these changes to the normal contralateral side. The study outcome is to compare the 3-D changes in the alveolar bone and dental roots between the 2 interventional techniques (segmentalT-loop and piggyback NiTi traction) methods.
