Официальное название
Effect of Posterior Disarticulatory Resin Bite Turbos on the Rate of Maxillary Expansion Using HYRAX Expander in Early Adolescent Patients: Randomized Controlled Clinical Trial
Обзор
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.
Подробное описание
This study is conducted as part of a Master's thesis in Orthodontics and aims to investigate the influence of posterior disarticulatory resin bite turbos on the rate of maxillary expansion achieved using a HYRAX expander in early adolescent patients.
The study evaluates whether modifying occlusal contacts can affect skeletal and dental responses during rapid maxillary expansion.
Participants will be monitored clinically throughout the expansion phase.
Participants will be assigned in two groups:
group 1: with posterior bite turbos group 2: without posterior bite turbos
Digital intraoral scans will be taken on a weekly basis to assess changes in maxillary dimensions and to accurately measure the rate and pattern of expansion over time.
These serial digital records provide high-resolution, non-invasive documentation of treatment progress.
CBCT will be taken before the expansion and after retention phase for skeletal and dental measurement .
Вмешательства
- Устройство 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. - Устройство 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.
Первичные конечные точки
- The effect of occlusal disarticulation on the rate of maxillary expansion by linear measurements made on digital models [Срок оценки: Baseline and weekly during the active phase of expansion and after 3 months of retention]
Вторичные конечные точки (2)
- -The effect of the posterior disarticulation on alveolar bone changes by CBCT . [Срок оценки: baseline and after three months of retention after complete active expansion]
- pain felt by the patient after activating the expansion screw [Срок оценки: first two weeks in active phase of expansion]
