3D Computer-Assisted Planning and Treatment for Dentofacial Deformities Using Orthognathic Surgery

What this Trial Is About

Dentofacial deformities involve significant differences from normal facial proportions and tooth alignment, causing difficulties in chewing, swallowing, speaking, and affecting facial appearance. These issues can lead to psychological distress due to facial disharmony and impaired social interactions. The conditions studied mainly involve skeletal differences between the upper and lower jaws that cannot be corrected with orthodontics alone, requiring combined orthodontic and surgical approaches for effective treatment. The study evaluates a full 3D computer-assisted workflow for diagnosing and correcting dentofacial deformities, focusing on orthognathic surgery. This surgery repositions the jaws in three dimensions to correct malocclusions such as Class 2, Class 3, and facial asymmetries that are not treatable by orthodontics alone. The process uses advanced imaging techniques like CT scans and 3D cephalometry, along with computer-assisted surgical planning and CAD-CAM devices to simulate and guide surgery. The treatment follows phases including pre-surgical orthodontics, surgery, and post-surgical orthodontic stabilization. Participants undergo three main study periods initial 3D documentation before treatment T0, preoperative documentation one month before surgery T1, and final documentation within 12 months after completing treatment T2. Researchers collect detailed imaging and clinical data at each stage to analyze treatment outcomes over 18 months. The study monitors jaw position, facial structure, and occlusion changes, aiming to improve planning and communication between surgeons, orthodontists, and patients throughout the treatment journey.
