3D accuracy analysis of a new surgical planning technique for jaw surgery

Splintless Virtual Surgical Plan with Mandible-first Technique in Orthognathic Surgery: Tridimensional Accuracy Analysis

Observational I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio · NCT06907745

This study is testing a new way to plan jaw surgery without using splints to see if it helps improve the accuracy of the surgery for patients with jaw deformities.

What this trial studies

This observational study evaluates the accuracy of a splintless virtual surgical plan using a mandible-first technique for patients with dentofacial deformities. It involves a three-dimensional superposition of post-operative volumetric CT scans and digital therapeutic project files to assess surgical outcomes. The study aims to improve surgical precision and patient outcomes in jaw surgery. Participants will undergo bimaxillary osteotomy as part of their treatment.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 18 to 60 with a diagnosis of dento-skeletal dysmorphosis affecting the middle and lower face who are in good general health.

Not a fit: Patients with a history of maxillomandibular fractures, those on anticoagulant or certain other medications, or those with uncontrolled systemic conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the accuracy of surgical planning and improve recovery outcomes for patients with dentofacial deformities.

How similar studies have performed: While this specific approach is novel, similar studies assessing surgical accuracy in jaw surgery have shown promising results.
