Optimized 3D virtually planned intermediate splints for bimaxillary orthognathic surgery: a clinical validation study in 20 patients

Orthognathic surgery is indicated for the treatment of significant skeletal malocclusions and facial dysmorphosis. Recent technological developments allow surgeons to virtually plan the orthognathic jaw movements. When producing intermediate splints, overlap between the upper and lower dentitions can occur. Autorotation of the mandible is often used as a solution for this problem. The purpose of this study was to present an optimized approach to fabricate digital intermediate splints based on the use of a scanned thick wax bite to overcome dental overlap during planning.
