Surgical operation steps

1. The doctor discusses the operation plan with the patient, carries out the operation after the patient agrees, carries out the orthodontic treatment according to the plan, eliminates the interference of the teeth, and enables the operation to smoothly move the cut bone segment to the designed correction position.

2. According to the specific situation of orthognathic treatment, evaluate and guess the surgical plan, and adjust it if necessary.

3. Preoperative preparation was performed for the patients, and further analysis was made on the surgical plan, expected effect and possible problems.

4. The patient underwent orthognathic surgery.

Orthognathic surgery is complex and delicate.In order for the surgeon to be able to easily move the bone segment during the operation, accurate positioning of the jaw bone, it is necessary for the orthodontist to complete some work before surgery, this is the content of preoperative orthodontics.It mainly includes: alignment of dentition, elimination of dental fetal interference, elimination of upper and lower anterior teeth compensatory lip inclination or tongue inclination, so that orthognathal surgery can be carried out normally.This can not only simplify the surgical process, so that some patients can avoid the operation of the double jaw, but also reduce the chance of postoperative recurrence and stabilize the surgical effect.Preoperative orthodontics is an important step to ensure the success of surgical orthodontics.

Oral and maxillofacial deformity refers to the abnormal size and shape of the maxilla caused by the abnormal development of the maxilla, the abnormal relationship between the upper and lower maxilla and its relationship with other craniofacial bones, as well as the abnormal relationship between the maxilla and teeth, the abnormal function of the oral and maxillary system and the abnormal facial morphology.The purpose of orthognathic surgery is to correct the misplaced teeth, adjust the discordant dental arch and the relationship between teeth and jaws, eliminate the interference between teeth and jaws, arrange the dentition, and eliminate the compensatory inclination of teeth, so as to enable the operation to move the incised bone segment to the designed correction position smoothly, and establish a good relationship between teeth and jaws.

Orthognathia belongs to the category of oral and maxillofacial surgery, which is a surgical treatment for some patients with serious malocclusion and cannot be completely achieved through pure orthodontics.Orthognathia is an invasive procedure in which the bone shape is adjusted according to the occlusal criteria of the teeth after the fracture is artificially caused to achieve a satisfactory result.Secondly, what are the indications for orthognathia: as mentioned above, patients with mild malocclusion have chosen orthodontics, that is, people often say to wear braces;If serious wrong jaw, pure scope of orthodontic force and the ability to reach improvement goals, there needs to be done are jaw surgery, combined with preoperative orthodontic treatment after the operation, to achieve good to improve the effect of surface type, such as the most common jaw thrust forward, central sag, and small chin, etc., through the opening of the artificial bone tissue, formation of straight section, and then in titanium nail plate fixed to the target location.For patients with mandibular protuberance, it is to push the chin back, the middle of the face is depressed patients, it is to move the jaw forward and so on.Generally, the orthognathia has an immediate effect on the change of facial shape, and the effect is significant. Through the recovery period of one to three months, plus the postoperative orthodontics, the patients can be completely different before and after surgery.
