The impact of surgery-first approach on the oral health-related quality of life: a systematic review and meta-analysis. surgery was established, with two surgical procedures considered at unstable: (1)maxillaryexpansion withsemi-rigid internal fixationevaluated with thedentallevelin posteriorregion,and(2)clockwiserotationof mandible rigid internal fixation of bicortical screws in the sagittal direction. General anesthesia allows surgeons to perform dentofacial osteotomies effectively without involuntary muscle movement or complaints about minor pain. Orthognathic surgery is one of the most common treatments for bone deformities of the jaw, such as prognathism or facial asymmetry. Furthermore, those that have been conducted have led to conflicting results. Orthognathic surgery is required to correct an underbite that is caused by the improper development and positioning of the jawbones. Also, a total maxilla osteotomy is used to treat the "long face syndrome," known as the skeptical open bite, idiopathic long face, hyper divergent face, total maxillary alveolar hyperplasia, and vertical maxillary excess. Often, these abnormalities cause difficulty associated with chewing, talking, sleeping, breathing and other routine activities. Int J Surg. Reciprocating saws are straight and are used for making straight bone cuts. NLM Dr. Raffaini introduced this technique in 2002 after a four-year study done with local anesthesia and assistance from intravenous sedation. It’s also referred to as orthognathic surgery.

This procedure is intended for patients with an upper jaw deformity, or with an open bite. Surgical orthodontic treatment is a type of orthodontic treatment used to correct severe cases when jaw bone discrepancies are present and when a proper bite cannot be achieved with orthodontic treatment alone. Most of the swelling will disappear in the first few weeks, but some may remain for a few months. Immediately after surgery, patients must adhere to certain infection preventing instructions such as daily cleaning, and the consumption of antibiotics. [29] [16] Infection rates of up to 7% are reported after orthognathic surgery; antibiotic prophylaxis reduces the risk of surgical site infections when the antibiotics are given during surgery and continued for longer than a day after the operation.[17]. Forward movement of the maxilla is reasonably stable, with or without rigid internal fixation, but mandibular setback often is not stable, and downward movement of the maxilla that creates downward rotation of the mandible is unstable. During an orthognathic surgery to correct an open bite, the orthognathic surgery performed will always be bimaxillary, to correctly position both the mandibular and the maxillary arch, usually by making rotational and orbital movements.
