What is Bone-Anchored Maxillary Protraction?

BAMP stands for Bone-Anchored Maxillary Protraction, an orthodontic surgical method to correct skeletal Class III malocclusion, typically characterized by an underdeveloped upper jaw (maxilla), often seen in cleft palate patients or those with facial growth discrepancies.

​

Instead of using traditional facemasks anchored to teeth—which can cause unwanted dental movements—BAMP uses small miniplates (anchor plates) surgically placed into the bones of the upper (zygoma/infrazygomatic crest) and lower jaw (mandibular symphysis). Elastics are attached between these plates to gently pull the upper jaw forward.

​

2 types of BAMP protocols:

  1. Type 1 BAMP: Anchors only in the upper jaw, typically paired with a facemask for protraction. 

  2. Type 2 BAMP: Anchors in both the upper and lower jaws, using intermaxillary elastics (class III elastics) to apply continuous forward force.

​

Type 2 tends to produce more skeletal movement with fewer dental side effects.

How is BAMP done?

​​​​

  1. ​You will have a consult and CBCT scan to determine your malocclusion.

  2. The surgery will take place in the office, where you will be fully under anesthesia.​

  3. The surgery will occur inside your mouth, preventing facial scarring, where the surgeon will make use place tiny plates and screws into the upper and lower jaw. 

  4. Follow your instructed recovery plan for 1-3 weeks. In general, you will have to keep your mouth clean, not overstrain your jaw, not smoke, have a liquid diet that eases into a soft diet, and take pain, antibiotic, and inflammation medications. 

  5. Afterwards, you will meet with your orthodontist, who will slowly adjust the elastics on the plates to adjust your upper jaw to the correct position. This could take 1-2 years.

  6. Once your jaws are finished adjusting, they will be removed in a smaller surgical procedure that can take place in office. You will be sedated and the screws and plates will be removed. Dissolving stitches are done to close the wound.
