Post-surgical stability in mandibular advancement using postsurgical versus presurgical computer guided functional appliance

Purpose: Class II patients presenting with retrognathic mandible tend to conceal their deformity by protruding the mandible forward to achieve a more esthetic profile. Thus, they present with an unstable condylar position. This study aimed to assess the post-surgical stability in mandibular advancement using presurgical versus post-surgical computer guided functional appliance.
