Class III Malocclusion Clinical Trial
Official title:
The Effect of Splint Usage in Laterognathic Cl III Orthognathic Surgery Patients: Controlled Clinical Trial
It is crucial to maintain the anatomic condylar positions during orthognathic surgery. Condylar positions are affected directly under general anesthesia because of joint and muscle relaxation. Possible unwanted changes in the joint position may cause incorrect positioning of the jawbones. This could affect the success of the surgery in terms of function and facial aesthetics causing the need for a second surgery. Our aim is to evaluate whether the use of MR Splint has a statistically significant effect on muscle relaxation-induced condyle position deviations under general anesthesia in Class III Laterognathia patients.
It is crucial to maintain the anatomic condyle positions during orthognathic surgery to prevent iatrogenic temporomandibular joint complications. Condyle shunts are affected directly under general anesthesia because of the joint and muscle relaxation. Surgical guidance appliances are prepared according to the TMJ records taken chairside while patients are in an upright position. During surgery, these appliances are applied in a supine position while the muscles are relaxed. Postoperative and long-term effects of TMJ and muscle relaxation obtained under general anesthesia in class III and asymmetric patients will be examined. Patients who had occlusal splint before records taken will be evaluated in terms of condyle location by MPI. Our aim is to evaluate whether the use of MR Splint has a statistically significant effect on muscle relaxation-induced condyle position deviations under general anesthesia in Class III Laterognathia patients. ;
