Overview

NCT ID: NCT07739498
Lead Sponsor: Mansoura UniversityOTHER
Official Title: Effect of Posterior Disarticulatory Resin Bite Turbos on the Rate of Maxillary Expansion Using HYRAX Expander in Early Adolescent Patients: Randomized Controlled Clinical Trial
Brief Summary: This randomized controlled clinical trial aims to evaluate the effect of posterior disarticulatory resin bite turbos on the rate of maxillary expansion using a HYRAX expander in early adolescent patients. Participants will be randomly assigned to receive either maxillary expansion with posterior resin bite turbos or conventional expansion without bite turbos. The study will assess and compare the rate and effectiveness of maxillary expansion between the two groups during the treatment period. Clinical measurements will be recorded to evaluate skeletal and dental changes associated with the intervention.

Participant Group/Arms

group 1: HYRAX with posterior bite turbosExperimental

Participants in this arm receive a HYRAX rapid maxillary expansion appliance combined with posterior disarticulatory resin bite turbos. The bite turbos are placed on posterior teeth to achieve occlusal disclusion, aiming to minimize occlusal interference during expansion and potentially enhance skeletal response. The HYRAX expander is activated according to a standardized protocol throughout the treatment period, with regular follow-up using clinical assessment and weekly intraoral scans.

Device: Intervention 1: HYRAX expander with posterior disarticulatory resin bite turbos

Group 2 : Expansion without posterior bite turbosActive Comparator

Participants in this arm receive a HYRAX rapid maxillary expansion appliance without the use of posterior disarticulatory resin bite turbos. The appliance is activated according to a standardized expansion protocol similar to the experimental group. Patients are followed throughout the treatment period with regular clinical assessments and weekly intraoral scans to monitor changes in maxillary dimensions.

Device: Intervention 2 (Control): HYRAX expander alone
