Three-dimensionally Printed Hyrax Versus Conventional Hyrax for Maxillary Arch Expansion in Adolescents
Three-dimensionally Printed Hyrax Versus Conventional Hyrax for Maxillary Arch Expansion in Adolescents: A Randomized Controlled Trial
Ain Shams University
22 participants
Aug 1, 2025
INTERVENTIONAL
Conditions
Summary
This clinical trial aims to compare the skeletal and dental effects of conventional Hyrax expanders and 3D-printed Hyrax expanders in adolescent patients with maxillary transverse deficiency. Using cone-beam computed tomography (CBCT) and digital models, the study evaluates the precision, customization, and treatment outcomes of both appliance types to inform evidence-based orthodontic treatment planning.
Eligibility
Inclusion Criteria4
- Patients aged between 12 to 17 years.
- Skeletal age ranges from CVMS 3 to CVMS 5.
- Skeletal maxillary transverse deficiency with/without crossbite.
- Cooperative and able to attend follow-up visits.
Exclusion Criteria5
- Previous orthodontic treatment.
- Craniofacial syndromes, or cleft lip and/or palate.
- Patients with vertical growth pattern.
- Very bad oral hygiene and active periodontal disease.
- Vulnerable groups such as individuals with cognitive impairments or intellectual disabilities and individuals with severe mental health disorders.
