''Comparative Evaluation of Change in Bite Force and Levels of Bone Turnover Markers CTX and BALP in Hyperdivergent and Hypodivergent Cases During Retention Phases-A Prospective Clinical Trial ''

Not applicable Interventional Postgraduate Institute of Dental Sciences Rohtak · NCT06456827

This study is testing how bite force and certain bone markers change in young adults after orthodontic treatment, comparing those with different growth patterns in their jaws.

What this trial studies

This clinical trial aims to compare the changes in bite force and levels of bone turnover markers (CTX and BALP) in patients who have completed fixed orthodontic treatment, categorized into two groups based on their craniofacial growth patterns: hyperdivergent and hypodivergent. The study will be conducted in a single-blind, two-arm parallel design, where patients will be monitored for changes in bite force and biomarker levels over time. The sample size is calculated to include 20 non-growing patients aged 18-25, ensuring optimal occlusion and periodontal health. Data will be collected at multiple time points to assess the retention characteristics of dentition post-treatment.

Who should consider this trial

Good fit: Ideal candidates are non-growing patients aged 18-25 who have completed fixed orthodontic treatment with specific growth patterns.

Not a fit: Patients with incomplete orthodontic treatment, TMJ disorders, or systemic diseases affecting bone growth may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into optimizing retention strategies for orthodontic patients, potentially reducing relapse rates.

How similar studies have performed: While there are existing studies on bite force and orthodontic retention, this specific comparative approach focusing on growth patterns is relatively novel.
