Clinical Accuracy of Bimaxillary Surgery Completed with Custom Prefabricated Splints vs. Patient-specific Surgical Guides and Plates

Abstract Purpose Virtual surgical planning (VSP) has improved outcomes in bimaxillary orthognathic surgery when compared to traditional cephalometric analysis and model surgery. However, several studies have shown discrepancies between the planned and post-operative position of the maxilla with the use of VSP and splints. Patient-specific Implants (PSIs) have the maxillary movement and final position built into them as dictated by the virtual surgical plan, completely independent of the mandibular position and have shown promising results, but are limited in number and by sample size and no study to date has directly compared the accuracy of splints versus PSIs.
