The eligible criteria are posterior cross-bite, mixed dentition, skeletal Class I relationship and prepubertal stage of cervical vertebral maturation. The patients will be split into three groups according to facial divergency (hyper-, hypo-, normodivergent subjects). For each subject, digital dental casts will be recorded before and after treatment using an intraoral scanner. To evaluate two-dimensional maxillary arch changes, linear measurements will be done. To study comprehensively the palatal shape, a set of 240 landmark and semi-landmarks will be digitized on the palatal vault. Then, Geometric Morphometric Analysis (GMA) will be performed to compare morphological variations of the palate among different vertical facial growth pattern groups.",[27,28],"Cross-bite","Malocclusion in Children","RECRUITING","2025-08-26",{"date":32,"type":33},"2025-09-03","ACTUAL",{"date":35,"type":33},"2024-07-17",{"date":37,"type":22},"2026-12-31",{"name":39,"class":40},"Fondazione Policlinico Universitario Agostino Gemelli IRCCS","OTHER",1,{"id":43,"slug":44,"hasResults":11,"nctId":45,"briefTitle":46,"officialTitle":47,"acronym":4,"eligibilityCriteria":48,"healthyVolunteers":11,"sex":17,"minAge":49,"maxAge":50,"enrollmentInfo":51,"targetDuration":4,"studyType":53,"phases":54,"briefSummary":56,"conditions":57,"keywords":62,"overallStatus":29,"whyStopped":4,"lastUpdateSubmitDate":67,"lastUpdatePostDateStruct":68,"startDateStruct":70,"completionDateStruct":72,"leadSponsor":74,"locationsCount":41},"100529047","impact-of-anterior-cross-bite-treatment-on-childrens-speech-performance-100529047","NCT06168695","Impact of Anterior Cross Bite Treatment on Children's Speech Performance","Impact of Anterior Dental Cross Bite Treatment on Children's Speech Performance and Their Quality of Life","Inclusion Criteria:\n\n* healthy cooperative children aged 8-10 years\n* have at least one or more maxillary permanent incisors in a crossbite relationship\n* fully erupted four first permanent molars\n* Angle Class I molar relationship and Class I skeletal relationship\n* the mother language of all the subjects was Arabic.\n\nExclusion Criteria:\n\n* Children with systemic illness or previous history of speech therapy\n* children who are ill-habituated or unable to follow up\n* children with previous orthodontic treatment\n* uncooperative children\n* Anterior skeletal or functional crossbite\n* presence of sucking habits","8 Years","10 Years",{"count":52,"type":22},50,"INTERVENTIONAL",[55],"NA","The goal of this prospective, single-arm clinical trial is to evaluate the speech performance of children with anterior dental crossbite before and after correction.
