Common types of dysgnathia

Underbite/overbite/facial asymmetry
facial asymmetries

Repositioning the upper or lower jaw to create an optimal overbite and profile normalization. Combination of upper and lower jaw surgery (maxillomandibular realignment)

Characteristics and complaints

An underbite is typically characterized by a flattened midface and a thin upper lip that sits behind the lower lip. Those affected almost always suffer from nasal breathing issues and chronic inflammation of the paranasal sinuses, as well as snoring. There is often no space for their tongue. This reverse overbite aggravates biting and chewing. An underbite also often strains the masticatory muscles and teeth and often requires additional orthodontic treatment.

The corrective surgery

Durch die Mundhöhle wird die Basis des Oberkieferknochens einschließlich der Nasenscheidewand gelöst. So kann der Oberkiefer in jeder Dimension verändert werden. Die Zunge gewinnt mehr Platz, die Nasenatmung wird verbessert und die Ästhetik wird harmonisiert.

Advantages of our surgical procedure

  • no exterior skin incisions
  • no jaw wiring
  • short surgery and short hospitalization
  • no blood products
  • no repeat surgery

Repositioning the upper jaw for an optimum overbite

An underbite is one of the most common types of dysgnathia. It is often referred to as prognathia (lat. “pro” = forward) because the lower jaw protrudes too much. The real problem here is the receded upper jaw. This leads to numerous consequences. In addition to the aesthetic impact, an underbite leads to problems biting, chewing and speaking. Excessive strain on individual teeth, the lower jaw and nasal obstruction are generally present.

Minimally invasive surgical techniques can correct each area of the jaw and facial bones without any external incisions or complicated wiring. Functional problems are corrected while improving facial symmetry and aesthetics. This treatment is usually carried out in cooperation with an orthodontist!

The surgical procedure

The aim of this surgery is to achieve perfect occlusion through realignment and harmonization of the facial profile. The procedure is carried out while the patient is under general anesthesia. A short incision is made at the level of the wisdom teeth, uncovering the lower jawbone. The bone is then divided using a minimally invasive technique. This allows us to move the section of the jaw supporting the teeth to the predetermined position. The realignment and occlusion are carried out using computer-generated templates.

Thanks to minimally invasive surgical techniques, you can eat, drink and brush your teeth at any stage.

If indicated, the costs of surgery and orthodontic treatment will be covered in part by statutory health insurance.

What should I pay attention to?

  • Cool the area often and well during the first three days
  • Good oral hygiene (children’s toothbrush, mouthwash)
  • Smoking can compromise the distraction result - smoking is prohibited!
  • Do not blow your nose for at least 2 weeks
  • Do not use arnica before the surgery, and no aspirin before or after the surgery!
  • Only eat soft foods for approx. 6 weeks post-surgery (e.g. pasta)
  • Physical exercise should be avoided for 6-8 weeks during the healing phase

Possible post-op

  • Due to general blockage in the nose, nosebleeds can occur up to 4 weeks post-surgery
  • Mild reversible numbness in the upper lip
  • Swelling goes down by 2/3 after approx. 2 weeks. Residual swelling can occur up to 4 months post-surgery
