It involves skills of radiographic interpretation and mental visualization. To master these, postgraduate students learn to interpret 2D and 3D X-rays to locate these canines accurately. This process demands the creation of mental models of the impaction and resolving it either by envisioning the canine's movement to its correct position or considering its removal. To facilitate this cognitive exercise, a 3D-printed simulator, derived from Cone Beam Computed Tomography scans, serves as a tool to allow students to experiment with various movement simulations, helping them select the most viable treatment approach.</div><div>This project aimed to assess the differences in expert and novice orthodontists’ clinical reasoning for impacted maxillary canines, and whether the addition of a 3D simulator would affect their reasoning. Thirteen (13) novices randomly assigned to a control and intervention group and three (3) experts took part in a Think-Aloud exercise to diagnose and treatment plan a case of bilaterally impacted maxillary canines. Experts and intervention group novices had the 3D simulator in addition to standardized patient records. Their responses were recorded and analyzed according to a coding scheme reflecting the clinical reasoning process. While experts demonstrated quick clinical judgment and found the 3D simulator redundant, novices were more uncertain and required additional cues. Novices using the 3D simulator described more elaborate treatment plans and had increased awareness of potential complications as compared to the control group.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"31 1","pages":"Pages 158-166"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141577844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
