Treatment of maxillofacial fractures can be divided into conservative treatment and surgical treatment. The treatment after a jaw fracture is usually done by open repositioning, which is usually referred to as surgical treatment. Conservative treatment is generally used for children with condylar fractures, without functional impairment and without significant displacement of the jaws. Open reduction surgery is currently preferred for the treatment of maxillofacial fractures because it allows for anatomical repositioning of the fracture and restoration of facial form and function. Compared to conservative treatment, open reduction treatment can shorten the fracture treatment period. For example, it often takes 3-4 weeks to treat maxillary fractures by intermaxillary traction (which refers to the traction of maxillary teeth and mandibular teeth with rubber bands to reset and fix the fracture), during which the inability to open the mouth leads to such disadvantages as difficulty in eating and language, difficulty in maintaining oral hygiene, secondary caries and periodontitis. If treated with open reduction surgery, the bite is restored immediately after surgery, without affecting the speech and with the ability to eat liquid food. Soft food can be eaten one week after surgery. In addition, the biological properties of fracture fixation materials are getting better and better, especially the absorbable materials are used for fracture treatment, and the problem of secondary surgical removal of traditional metal implants is less.
