This condition typically manifests with clinical symptoms such as crossbite, crowding of teeth, and impaired respiratory function. Genetic factors, early primary tooth loss, mouth breathing, thumb sucking, and abnormal swallowing are among the causes of maxillary narrowing. Treatment options vary depending on the patient's age and the degree of suture closure. In pediatric and adolescent patients, rapid (RPE) or slow (SPE) orthodontic expansion can be achieved with palatal expansion appliances. However, in adult patients, due to the less flexible bone structure of the maxilla, methods such as surgically assisted expansion (SARME) or mini-screw-assisted expansion (MARPE) are preferred. Recent studies have shown that MARPE can be effective as a non-surgical alternative in young adults and can provide direct skeletal expansion without damaging the teeth.",[26,27],"Maxillary Expansion","Maxillary Transverse Deficiency","RECRUITING","2026-01-02",{"date":31,"type":32},"2026-01-08","ACTUAL",{"date":34,"type":32},"2025-09-29",{"date":36,"type":20},"2026-05",{"name":38,"class":39},"Merve Kulaksız","OTHER",1,{"id":42,"slug":43,"hasResults":11,"nctId":44,"briefTitle":45,"officialTitle":46,"acronym":4,"eligibilityCriteria":47,"healthyVolunteers":48,"sex":16,"minAge":49,"maxAge":50,"enrollmentInfo":51,"targetDuration":4,"studyType":21,"phases":53,"briefSummary":54,"conditions":55,"keywords":56,"overallStatus":28,"whyStopped":4,"lastUpdateSubmitDate":63,"lastUpdatePostDateStruct":64,"startDateStruct":66,"completionDateStruct":68,"leadSponsor":70,"locationsCount":40},"100613154","3d-evaluation-of-maxillary-expansion-methods-100613154","NCT07262892","3D Evaluation of Maxillary Expansion Methods","Three-Dimensional Evaluation of the Effects of Different Maxillary Expansion Methods","Inclusion Criteria:\n\n* Children aged 6-12 years\n* Good oral hygiene and adequate patient cooperation\n* No previous orthodontic expansion treatment\n\nExclusion Criteria:\n\n* Systemic diseases affecting growth, bone metabolism, or craniofacial development\n* Craniofacial syndromes or congenital anomalies\n* Severe behavioral or cooperation problems\n* Previous orthodontic or orthopedic maxillary expansion\n* Patients undergoing medications that affect bone metabolism",true,"6 Years","12 Years",{"count":52,"type":20},60,[23],"This controlled prospective clinical trial aims to evaluate the effectiveness of different maxillary expansion methods in children with maxillary transverse deficiency.
