According to the retention theorem \"teeth which have been moved through orthodontic treatment tend to naturally return to their original position. It is hypothesized that significant differences will exist in tooth movement patterns between horizontal and vertical growers, with horizontal growers exhibiting more pronounced tooth movement in the vertical plane particularly in the overbite as compared to the vertical growers . Furthermore, it is expected that facial type will influence the stability of orthodontic treatment outcomes, with long-faced individuals showing more relapse of mandibular incisor alignment and crowding. By exploring this relationship, this study aims to provide valuable insights into the factors influencing orthodontic treatment outcomes and stability. With long-faced individuals exhibiting more mandibular backward rotation and short-faced individuals showing forward rotation, which increases the risk of deep bite . Additionally, understanding these factors is crucial for orthodontists to predict and prevent potential relapse, ensuring optimal treatment results and long-term stability. Hence, the present trial will be undertaken to assess the changes and compare If there is any difference in tooth movement in 3-Dimensional superimposition in the dentition in horizontal and vertical growers post orthodontically over a period of retention phase.",[27,28],"Retention","Relapse","RECRUITING","2026-05-30",{"date":32,"type":33},"2026-06-03","ACTUAL",{"date":35,"type":33},"2025-02-04",{"date":37,"type":21},"2027-07",{"name":39,"class":40},"Postgraduate Institute of Dental Sciences Rohtak","OTHER",1,{"id":43,"slug":44,"hasResults":11,"nctId":45,"briefTitle":46,"officialTitle":47,"acronym":48,"eligibilityCriteria":49,"healthyVolunteers":15,"sex":16,"minAge":17,"maxAge":18,"enrollmentInfo":50,"targetDuration":52,"studyType":53,"phases":4,"briefSummary":54,"conditions":55,"keywords":58,"overallStatus":63,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":69,"leadSponsor":71,"locationsCount":4},"100611108","3d-printed-vs-milled-occlusal-splints-in-dentistry-100611108","NCT07236294","3D Printed vs. Milled Occlusal Splints in Dentistry","Material and Clinical Assessment of 3D-printed vs. Milled Occlusal Splints: A Study on Performance and Durability in Dental Applications","Splints","Inclusion Criteria:\n\n* Subjects being healthy (ASA \\\u003CIV)\n* Subjects with healthy, complete dentitions (except for extractions of wisdom teeth, or tooth extractions for the purpose of orthodontic treatment in the past)\n* Subjects willing and able to participate in the study\n* Subjects willing to provide written informed consent for their participation in the study\n\nExclusion Criteria:\n\n* Subjects with dental issues other than the inclusion criteria\n* Subjects with a history of autoimmune disorder\n* Subjects with known allergies to acrylic materials\n* Subjects with severe allergies manifested by a history of anaphylaxis or those with severe, chronic allergies (e.g., asthma) and subjects with an active infection of any kind at the time of enrollment\n* Subjects who are pregnant or lactating\n* Subjects enrolled in another investigational clinical trial",{"count":51,"type":21},24,"6 Weeks","OBSERVATIONAL","This crossover study aims to evaluate the wear comfort, retention, and stability of 3D-printed and milled occlusal splints in healthy subjects.\n\nThe main question it aims to answer is:\n\nResearch questions\n\n\\- How do healthy subjects experience the wear comfort, fitting, retention and stability of a printed and milled occlusal splint? and how do clinicians experience the fitting, retention and stability of the splints?\n\nBy systematically assessing self-reported outcomes, this research seeks to contribute valuable insights into the practical applications of both technologies.
