Oral and Maxillofacial Surgery is a surgical specialty focusing on reconstructive surgery of the face, facial trauma surgery, the oral cavity, head and neck, mouth, and jaws, as well as facial cosmetic surgery. Most common oral and maxillofacial services include extraction (moderate to difficult, including wisdom teeth), reconstructive dental oral surgery, and placing dental implants. Oral and Maxillofacial Surgeons are specialists in the diagnosis and treatment of a broad range of disorders affecting the facial complex and skeleton, including the jaws and oral cavity. Contemporary training in both medicine and dentistry enables oral & maxillofacial surgeons to treat conditions requiring expertise in both fields. These include a range of common oral surgical problems (eg. impacted teeth, dental implants), jaw and congenital facial disproportion, facial trauma, oral cancer, salivary gland disease, temporomandibular joint disorders, and various benign pathologies (eg. cysts and tumours of the jaws).
