Comparing two methods of dental occlusion measurement in adult orthodontic patients

Quantification of the Differences in the Diagnostic Relationships Between Centric Occlusion Versus Maximum Intercuspation in Adult Orthodontic Patients : A Cross-sectional Study

Observational Cairo University · NCT06220955

This study is testing two different ways to measure how teeth fit together in adults getting orthodontic treatment to see which method gives better results.

What this trial studies

This observational study aims to quantify the differences in diagnostic relationships between centric occlusion and maximum intercuspation in adult orthodontic patients. It utilizes both conventional methods, including semi-adjustable articulators and face bow records, as well as a digital method involving a dental intraoral scanner. The study focuses on various orthodontic relations such as molar, canine, and incisor relations, as well as overjet, overbite, and midline discrepancies. By comparing these methods, the study seeks to enhance the accuracy of orthodontic diagnostics.

Who should consider this trial

Good fit: Ideal candidates for this study are adult orthodontic patients with full permanent dentition.

Not a fit: Patients who have undergone previous orthodontic treatment, syndromic patients, or those with retained primary teeth or heavily restored teeth may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the precision of orthodontic assessments, leading to better treatment outcomes for patients.

How similar studies have performed: While similar studies have explored occlusion measurement methods, this specific comparison of conventional and digital techniques is relatively novel.
