What this trial studies

This study evaluates the effectiveness of patient-specific implants (PSI) versus conventional mini-plates in bimaxillary orthognathic surgery for patients with mandibular retrognathia and Angle Class II malocclusion. The approach involves using 3D-printed titanium implants designed to fit the unique anatomy of each patient, which may enhance the accuracy of bone positioning during surgery. The accuracy of the surgical outcomes will be measured by comparing the actual positions of the bones post-surgery to the planned positions. This method aims to improve surgical precision and patient outcomes in jaw alignment procedures.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with mandibular retrognathia and Angle Class II malocclusion who require bimaxillary orthognathic surgery.

Not a fit: Patients with cleft lip, craniofacial syndromes, previous trauma, or obstructive sleep apnea may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate jaw alignment and improved functional and aesthetic outcomes for patients undergoing orthognathic surgery.

How similar studies have performed: Other studies have shown promising results with the use of patient-specific implants in surgical procedures, indicating potential for success in this approach.
