Orthognathic surgery

This study tests whether using two customized 3D titanium miniplates is as accurate as using four for transferring a virtual surgical plan to the actual jaw surgery. Ten patients with jaw misalignment will be randomly assigned to receive either two or four plates. The main goal i…

This study tests whether giving acetaminophen or ibuprofen before jaw surgery can lower pain after the operation. 72 adults having specific jaw procedures will be split into three groups: one gets IV acetaminophen, one gets IV ibuprofen, and one gets standard care without pre-sur…

This study uses eye-tracking to measure how people look at faces of patients before and after orthognathic surgery, which corrects jaw deformities. Researchers show photos of faces to healthy volunteers and record where they look, especially the lower face. The goal is to see if …

This study compares two methods for guiding jaw surgery: traditional computer-designed splints versus a newer guide system that attaches to both teeth and bone. The goal is to see which method is more accurate and leads to better stability after surgery. About 50 adults with jaw …

This study observes adults aged 18 to 40 undergoing bimaxillary orthognathic surgery (corrective jaw surgery) to track how heart rate, blood pressure, and oxygen levels change during the procedure. Researchers will also look for the trigeminocardiac reflex, a sudden drop in heart…

This study looks at whether corrective jaw surgery (orthognathic surgery) can improve depressive symptoms and how patients see their own appearance. Researchers will compare questionnaire results from before and six months after surgery in 20 adults with different types of malocc…

This study looks at how orthognathic (jaw) surgery changes body posture and the pressure on your feet when standing or walking. Researchers will measure these changes before surgery and 6 months after in 60 people, comparing them to a similar group who did not have surgery. The g…

This study tests a computer model that simulates how a person's face will look after orthognathic (jaw) surgery. Researchers will compare the simulation to actual 3D scans taken 6 months after surgery in 30 patients. The goal is to give patients a reliable preview of their post-s…
