Preparing for Orthognathic Surgery . After Orthognathic or Jaw Corrective Surgery. New Splint for Orthognathic Surgery. The accuracy of using both methods for maxilla repositioning was quantitatively evaluated using linear and angular measurement. Nonetheless, the position of maxilla is still dependent on mandibular autorotation, no matter whether maxillary or mandibular surgery … Usually, surgical intermediate and final occlusal acrylic splints made on plaster models mounted on a semi-adjustable articulator, after facebow transfer, are used to reproduce the planning during surgery. The primary goal was to compare the accuracy of defined angles. A paradigm shift in orthognathic surgery? Thirteen patients who … Orthognathic surgery usually starts with pre-surgical orthodontics to correctly align the teeth so the Oral and Maxillofacial Surgeon is able to move the facial bones to their ideal position. The aim of the present study was to compare conventional (CSP) versus customized virtual surgical planning (VSP) in bimaxillary orthognathic surgery. Importing and combining these data into the preoperative planning situation allows the transformation of the planned repositioning and the ideal occlusion. Maxillofacial surgery as a discipline was not an organized specialty until the latter half of the 20th century requiring particularly trained surgeons with masterful knowledge of both anatomy and surgical techniques to accomplish successful bony reconstruction. Conclusions: In this pilot study it was demonstrated that clinically usable splints for orthognathic surgery can be produced by computer-assisted technology. surgical splint: general term for a device used to maintain tissues in a new position following surgery. around one to four weeks after surgery. The workflow process consists … Dental splints are used in orthognathic surgery with the traditional plaster study models.
