Digital 3D imaging and its application to midpalatal suture maturation assessment

Abstract

The incorporation of digital technologies in orthodontics, particularly in the area of maxillary expansion, represents a significant shift in research, diagnostic techniques, treatment planning, and the personalization of orthodontic devices. Rapid maxillary expansion (RME), which involves the separation of the midpalatal suture for maximal widening of the maxilla, is at the forefront of this digital integration. In complex cases where advanced suture maturation is present, miniscrew-assisted rapid palatal expansion (MARPE) and/or surgically assisted palatal expansion (SARPE) may be required. The use of cone beam computed tomography imaging and virtual appliance design allows for customized treatment plans to be created and implemented by clinicians. However, challenges still exist in the diagnostic process despite the use of digital technologies. This study aims to evaluate the midpalatal suture maturation stages of a group of patients using three-dimensional imaging and to assess the feasibility of using grayscale values for evaluating midpalatal suture maturation. One objective of this study is to establish a more objective method for assessing midpalatal suture maturation stages.
