Microimplants (TADs)

In the process of moving teeth, we are guided by the generally accepted laws of physics (biomechanics). Accordingly, the improvement of the technology of differentiated movement of the teeth becomes apparent, which ensures a faster and more predictable treatment result.

For a long time the patients have traditionally been using uncomfortable extraoral and intraoral devices - in order to retain teeth that do not require movement. They (the devices) could not guarantee the absolute stability of selected teeth.

One of the most of innovative developments in orthodontics is the introduction of an absolute skeletal anchorage (bone support) in the daily orthodontic practice - microimplants.

Microimplants – are high-tech mini screws that the orthodontist or the surgeon temporarily screws into the jaw bone to create reliable points of support necessary for the proper and correct orthodontic movement of the teeth.

Microimplants are made from pure titanium or its alloy. Because of this they are completely biocompatible with the tissue of the body. An orthodontic microimplant in contrast to an orthopedic one is significantly thinner (1.2-2 mm) and has a smooth surface.

The sequence of microimplant installation:

1. Do necessary x-rays to determine the exact number and location of installing the microimplants.

2. The surface of the mucous membrane of the proposed location of the implant is sprayed with special anesthetic spray or gel.

3. Local anesthetics of the selected area is done.

4. Microimplants are installed (screwed) to the thickness of bone tissue between the roots of the teeth, or in other areas intended for the installation of microimplants.

The installation procedure is completely painless and takes about 10-15 minutes.

The advantages of using microimplants in orthodontic practice:

  • Reduction in the time of orthodontic treatment.
  • Expanding the boundaries and possibilities of orthodontic camouflage treatment with a subsequent decrease in the indications for orthognathic surgery (removal of the gingival smile, open bite treatment ... etc).
  • Integrating microimplants with the expansion appliances, we obtain a more skeletal effect of expanding the upper jaw, especially in growing patients, as well as the possibility of its unilateral expansion.
  • Improvement in the biomechanics of lingual orthodontics.
  • The use of microimplants gives more predictable results and reliability of orthodontic treatment, as the course of treatment is controlled more by the doctor and to a lesser extent depends on the patient.
  • Simple and painless microimplants installation process, which allows a wide application in daily orthodontic practice.

Possible risks and complications of installing microimplants:

1.Because of the different shapes of the roots of the tooth there is a slight chance of contact of the microimplant with the root surface or its penetration into the tooth root. To avoid this, X-ray is performed before the installation. If, nevertheless, there has been a contact of the microimplants with the surface of the tooth root, then, changing the direction of setting the screw will help the root surface recover and heal very quickly.

2. There is a small probability of microimplant damage during the procedure of its installation. If the microimplant breaks, the remaining portion can be removed surgically under local anesthesia without any further complications.

3.After installing the microimplant subsequent application of force may reduce its stability. The likelihood of such events – is about 1 to 3. The weakening of the stability of the microimplant may be due to particular structural features of the patient's bone, large force of masticatory muscles or as a result of contact of the microimplant with the surface of the root.

4. There is a slight risk that the microimplants can be rejected by the body (this applies to any implant). If this happens, the microimplant is removed, after that a new microimplant is installed in the other place.
