The cost of the surgery for the circumcision, or antimandibular, varies with the age of the patient, with an overall range of roughly $3,000 to $80,000. If the child is cooperative and the correction is done at the age of 3.5~5 years old, the MRC appliance can be used to correct the anti-mandibularity at a cost of about $3,000. 5~7 years old children tend to use push-spring movable orthodontic treatment at a cost of about $3,000. 8~10 years old are usually treated with expanded arch movable orthodontic appliances at a cost of about $5,000. after the age of 12 years old the treatment is done through orthodontic treatment at a cost of about $20,000. For more severe cases, such as bony problems, combined orthodontic treatment is required, costing about $50,000 to $80,000. The cost may vary from region to region, but early treatment is less expensive and should be done as soon as possible.
