What this trial studies

This clinical trial aims to compare the surgical accuracy and efficiency of 3D-printed patient-specific titanium surgical plates against conventional surgical plates in jaw reconstruction. It is a randomized controlled trial involving patients with maxillary or mandibular neoplasms, inflammatory conditions, or congenital diseases requiring reconstructive surgery. The study will evaluate the primary endpoint of reconstruction accuracy and secondary endpoints related to surgical outcomes. Participants will undergo computer-assisted surgery with either type of plate to determine which method yields better results.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with maxillofacial benign or malignant tumors or other conditions requiring jaw reconstruction.

Not a fit: Patients who are pregnant or have systemic conditions that impair bone healing may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more precise and efficient jaw reconstructions, improving patient outcomes.

How similar studies have performed: Previous studies on 3D printing in surgical applications have shown promising results, indicating potential success for this approach.
