Buck teeth correction is divided into orthodontic correction and orthognathic surgical correction, orthodontic correction is the use of mechanical force to slowly align the teeth within the arch to retract the anterior teeth, orthognathic correction is the use of surgery to trim the jawbone. 1. Orthodontic correction: for mild to moderate teeth protrusion is often caused by malocclusion, orthodontic correction is the use of the mechanical force of the orthodontic appliances, so that the teeth slowly move within the jawbone, inwardly retracted anterior teeth, so that the teeth to form a normal overjet cover. 2. Orthognathic correction: For severe anterior protrusion of teeth, it can be seen that it is caused by overdevelopment of jawbone, which requires orthognathic surgery to trim the overdeveloped jawbone to form the correct maxillary and mandibular jaw cover, and then fix it with titanium plate to make the face normal, but orthognathic needs to be combined with orthodontics to carry out the treatment. The exact course of orthodontic surgery for buck teeth is related to the orthodontic program, and it is recommended to consult a medical professional for advice.
