Surgical Orthodontic Treatment of Class III Malocclusion with Unstable Condylar Position and Facial Asymmetry

In the orthodontic treatment including orthognathic surgery, post-operative relapse has been the most distressing concerns for both orthognathic surgeons and orthodontists. The proximal segments of the mandible should be positioned properly in the articular fossae during the orthognathic surgery for post-operative stability. However, it is difficult for the orthognathic surgeons to control the positioning of proximal segments during the surgery due to muscle relaxation and the harsh intra-operative environment, especially if the temporomandibular joint (TMJ) structures are not stable in their functional area. Therefore, the mandible should be stabilized with a pre-surgical stabilization splint to provide proper stimulation that forms a pseudodisc and promotes stabilization of the surrounding TMJ structures before any active surgical procedures.
