Common types of dysgnathia

Narrow upper and lower jaw

Surgical palatal expansion (SPE) for the widening of the upper jaw Mandibular split osteotomy (lower jaw distraction) for expansion of the lower jaw

Characteristics and complaints

People with a smaller upper jaw often have very crooked teeth. This makes oral hygiene more challenging and strains your jaw. Jaw, head and neck pain are common consequences of this. An upper jaw that is too small is often associated with a flat midface and a retrusive upper jaw. Those affected often snore as nasal breathing is obstructed.

Upper jaw appliances

The corrective surgery

Expansion allows the upper jaw to widen. This procedure is largely pain-free and is carried out with the help of an appliance that sits firmly in your mouth. Before we do this, the jawbone is slightly weakened through a small incision in the oral vestibule.

Advantages of our surgical procedure

  • correction of crowding without losing natural teeth
  • short orthodontic treatment
  • quick recovery = short sick leave
  • genuine creation of space through bone growth
  • no exterior skin incisions
  • no jaw wiring
  • short surgery and short hospitalization
  • no blood products
  • no repeat surgery

Procedure
Targeted expansion of the upper jaw Surgically assisted Rapid Palatal Expansion (RPE)

Rapid Palatal Expansion (RPE) is a safe procedure targeting crowding. It creates room in the upper jaw without having to remove healthy teeth.

The orthodontist inserts the expansion appliance before surgery. The procedure (duration of 30 min) is carried out while the patient is under general anesthesia. The surgeon performs the procedure exclusively via the oral cavity to avoid external scars. The four maxillary buttresses are then weakened in order to allow the expansion (distraction) of the upper jawbone. This procedure enables the build-up of bones and creates more room in the upper jaw. Directly after this surgery, you will notice a small gap between your upper front teeth. This gap will continue widening during the expansion phase until an orthodontist closes it.

The inpatient stay is limited to two days, and the first follow-up examination usually takes place one week later. The expansion appliance stays in place for four months (depending on the extent of crowding).

Procedure

During the expansion process (1 week post op), you will have to turn the expansion appliance (1x morning, 1x night). This procedure is pain-free. The orthodontist will carry out regular check-ups in consultation with our team. Sick leave is limited to approx. one week.

Please do not hesitate to contact our team if you have any questions.

What should I pay attention to?

  • Cool the area often and well during the first three days
  • Good oral hygiene (children’s toothbrush)
  • You are not allowed to blow your nose for two weeks
  • Smoking can compromise the distraction result - smoking is prohibited!
  • Do not use arnica before the surgery, and no aspirin before or after the surgery!
  • Only eat soft foods for approx. one week post-surgery
  • Physical exercise is allowed after approx. two weeks, only after prior consultation

Possible post-op complaints
nach der OP

  • Mild and reversible numbness in the upper lip
  • Mildly loose front teeth in the upper jaw
  • The loose upper jaw can make slight cracking sounds during the first week
