Distal occlusion

In dentistry, there are several types of irregular positioning of the upper and lower jaw. One of the most common pathologies is the prognathic or distal occlusion, according to statistics, it occurs in almost half of the patients who have turned to the orthodontist.

In addition to unsatisfactory appearance, with this problem, a number of complications are noted - a violation of the functions of swallowing and chewing, a disruption of the temporomandibular joint. The risk of tartar formation and caries development also increases.

What is a deep distal bite?

The described defect is characterized by excessive protrusion of the upper jaw, while it overlaps the lower jaw severely. In addition, all upper and lower teeth move relative to each other - they are closed unpaired.

Prognatic bite is usually accompanied by obvious external signs:

Is it possible to correct a distal occlusion without surgery?

Contrary to the fears of most patients, the presented occlusion is extremely rarely subject to surgical therapy. Surgical treatment of distal occlusion with the help of osteotomy is performed only in the most neglected and severe cases in the presence of indications:

Also less invasive techniques are used for correction of occlusion - hardware-surgical and prosthetic technologies, their combination.

As a rule, the problem can be eliminated by means of bracket systems. They are effective even in adulthood.

Correction of distal bite by braces

To obtain sustainable desired results, you will have to be patient and patient, as the treatment of prognathic occlusion will take a long time, about 3-4 years.

During this period, it is necessary to constantly and round the clock to wear braces , correction of which will be performed by the orthodontist in accordance with the developed therapy plan. In some cases, this method of treatment is complemented by the use of hardware technologies:

It is worth noting that even after the removal of the bracket system, long-term therapy and fixation of the effect is required. For this purpose, the use of removable or stationary retention devices, trainers (retainers) for the next 4,5-8 years is assigned. Sometimes it is necessary to finish the treatment with surgical methods - compactotestomy, removal of some teeth.

Myogymnia with distal occlusion

Given the danger of inflammation and degenerative changes in the temporomandibular joints, it is important to take care of strengthening the surrounding muscles. Orthodontists recommend for their training to consistently perform several simple exercises from the myogym test:

  1. Inflate and deflate cheeks.
  2. Pull the lips into the tube.
  3. Stretch your mouth in a smile.
  4. Pull out the lower jaw in front of the upper jaw.
  5. Open your mouth wide.

It is also useful to inflate balloons, put out candles with your breath, often smile.

It is desirable that the exercises are carried out in the morning and slowly. On their implementation should be allocated at least 10-15 minutes, do slowly.
