Background: Regenerative endodontic procedures (REPs) are innovative treatments aimed at restoring damaged dental structures. However, the effect of orthodontic movement on REP-treated teeth is not well understood and may have significant long-term consequences. This study aimed to evaluate the impact of orthodontic movement on a mature permanent tooth associated with dens invaginatus that has undergone a regenerative endodontic procedure (REP).
Case Presentation: This report describes the case of a 13-year-old healthy male who presented with pulp necrosis and a chronic apical abscess (tooth number 2.2). Following REP according to the American Association of Endodontists' guidelines, the patient began non-extraction orthodontic treatment with fixed appliances after a 9-month healing period, which lasted 17 months in the upper arch. Subsequent follow-ups at 24, 36 and 48 months post-REP revealed an asymptomatic state with minimal cervical discoloration and diminished cold sensitivity. Radiographic analyses revealed periapical healing, mild apical remodeling on tooth 2.2, and moderate apical remodeling on other maxillary incisors. The treated tooth displayed a positive response to both REP and orthodontic treatment, yet further research is required to determine the long-term effects of orthodontics on REP-treated teeth.
Conclusion: Orthodontic movement following REPs in mature permanent teeth is feasible and do not seem to prone teeth to orthodontic tooth resorption. Our experience indicates that a 9-month healing period allows successful orthodontic outcomes following REPs. Nonetheless, the predictability of outcomes and the ideal healing period before orthodontic movement is initiated remain to be established.

Background Orthodontic treatment, while primarily focusing on correcting dental alignment and occlusion, has been increasingly validated for its potential impact on broader aspects of oral health and general well-being: its potential influence on body weight. While the mechanical effects of orthodontic appliances are well documented in the literature, their potential behavioral impact on weight loss remains underexplored. Beyond its primary role in correcting dental alignment, our study has unveiled a lesser-known benefit: its potential to aid in weight reduction among individuals who have already struggled through conventional methods.

Materials And Methods: The increase of the radiographic root area (RRA) of each REP tooth was measured at each follow-up visit after the end of orthodontic treatment. The study included two experimental groups of patients aged 7-17 with REP-treated teeth.
Objective: A 26-year-old woman came for orthodontic treatment to improve her profile with protrusive lips. Diagnosed as bimaxillary protrusion, extraction followed by anterior retraction was indispensable for the case. However, her left upper lateral incisor was absent, the left upper canine had moved mesially and replaced the adjacent incisor, and the original canine location was restored with a long implant, which was in good condition.

According to the visual treatment objective, the nonextraction treatment plan showed advantages in the type of orthodontic tooth movement and final occlusal relationship. Therefore, considering the favorable periodontal treatment results and single-root teeth, the hopelessly migrated maxillary canines were relocated, eliminating the existing trauma from occlusion.

Introduction: This study aimed to assess the root resorption and alveolar bone changes of maxillary incisors volumetrically and 3-dimensionally in patients with Class II Division 1 malocclusion who underwent treatments involving the extraction of 4 first premolars with conventional fixed appliances (FAs) vs clear aligners (CAs).
Methods: A total of 320 maxillary incisors from 80 patients were assessed and divided into 2 groups (FAs and CAs), each possessing similar baseline characteristics. Pretreatment and posttreatment cone-beam computed tomography scans were used to analyze linear and volumetric orthodontically induced inflammatory root resorption, alveolar bone thickness (ABT), alveolar bone height (ABH), as well as anteroposterior and vertical movements of maxillary incisors.
