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.

Conditions

  • Maxillary Transverse Deficiency Requiring Rapid Maxillary Expansion in Early Adolescent Patients

Interventions

DEVICE

Intervention 1: HYRAX expander with posterior disarticulatory resin bite turbos

Description: Arm 1: Participants in this group receive a HYRAX rapid maxillary expansion appliance combined with posterior disarticulatory resin bite turbos. The bite turbos are placed on the posterior teeth to disclude the occlusion, aiming to reduce occlusal interference and potentially enhance skeletal response during maxillary expansion. The HYRAX appliance is activated according to a standardized expansion protocol.

DEVICE

Intervention 2 (Control): HYRAX expander alone

Participants in this group receive a HYRAX rapid maxillary expansion appliance alone without the use of posterior bite turbos. The appliance is activated following the same standardized expansion protocol as the intervention group.
