Research summary
Surgery for a class III jaw
Children with reverse bite and large lower jaws have what is termed a class III skeletal pattern. In some cases, the problem is that the upper jaw is set too far back and the treatment is to bring it forwards to correct the reverse bite. Patients do not usually receive corrective treatment until their general and facial growth is complete at 17-18 years of age. At this point, they may be offered jaw surgery to correct the jaw position.Treatment options for class III jaw between 11-14 years.
At this age, patients are often distressed/ teased/ bullied about their jaw at a time when peer opinion is particularly important to them. Bone Anchored Maxillary Protraction (BAMP) has been used in Europe for 11- 14 years old children to correct their class III jaw relationship without having to wait until they have finished growing.BAMP consists of small metal plates that are inserted from inside the mouth into the front part of the cheekbone bone next to the upper molars on each side. Further miniplates are positioned into the bone down in the lower canine region near the front of the lower jaw. Elastics are then attached from the upper to the lower plates, via hooks, to bring the upper jaw and teeth forwards and correct the class III skeletal pattern. The miniplates are placed and later removed as a daycase general anaesthetic procedure and the patient wears the elastics for around 6-8 months.
