Abstract
The cephalometric radiography, dental model, intra-oral and extra-oral photos are essential traditional baseline data as orthodontic diagnostic tool to develop a comprehensive treatment plan. With the advent of the digital era, 3D digital dental model will gradually replace the traditional bulky plaster casts, and become an inevitable trend in the future. The purpose of this review article was to discuss about: (1) Digital dental models. (2) Pre-treatment and post-treatment stability of palatal rugae. (3) Via serial 3D digital dental model superimposition registered on palatal rugae and palatal vault, it is feasible to analysis the direction and magnitude of 3D individual tooth movement after orthodontic treatment. According to a comprehensive review of the literature, it is reliable to register on palatal rugae for 3D serial maxillary digital dental model superimposition. However, none of these studies demonstrated mandibular digital dental model superimposition directly since no stable reference landmark was established. Future Prospects: Via integration of digital dental models into cone beam computed tomography scans, and 3D serial digital dental model superimposition registered on palatal rugae and palatal vault, it is feasible to measure individual 3D tooth movement, and the most important construct a brand new 3D diagnostic tool and analysis method.
