Correction of mesial bite in a teenager

We are being seen by an orthodontist in Magnitogorsk. According to the results of the last examination there are several opinions: 1. it is necessary to remove 3 permanent teeth before installing a bracket system; 2. to install a bracket system without removing teeth, but then there is a possibility of extending the lower jaw during the eruption of wisdom teeth; 3. do nothing until the age of 15 years. Which option is better?

Based on the data provided, we can note that you are characterized by:

  1. Bite open in the anterior region;
  2. Mesial bite;
  3. Vertical type of growth of the facial skeleton;
  4. Severe crowding of teeth in the upper and moderate in the lower jaws; mainly a lack of space for 15 (retinated tooth from top right), 23 (upper left canine) and 33 (lower left canine);
  5. Tooth retention 15 (delayed eruption);
  6. The displacement of the center of the upper dentition along the face by 1 mm to the right.

Such a situation can be solved in the following ways:

  1. Correcting a mesial bite by moving the lower teeth backwards - this requires the space in the tooth row that we can get as a result:
    • distalization – when the entire dentition is moved backwards (up to 2 mm on each side): micro-implant support is required.;
    • separation – grinding the teeth in a safe volume, as a result of which they are reduced in size and free the necessary space (up to 2-3 mm on each side);
    • removals – as a last resort.
  2. Correction of open bite – extrusion of incisors (extending incisors to meet each other to close the bite and create an overlap) and / or introduction of upper molars (the last large teeth), possibly with the support of micro-implants (there is an age limit).
  3. Alignment of dental rows with or without tooth extraction and surgical relocation of jaws with correction of mesial and open bite (after 21-25 years of age).
  4. Creating space for the upper left canine 23 and retined premolar 15 on the upper right
    • removal;
    • distalization;
    • forward tilt of the front incisors;
    • separation;

Recommendations:

  1. There is a high probability that teeth should not be removed.
  2. The growth of the mandible will continue regardless of the treatment plan until the age of 21. After completion of orthodontic treatment, retainers will be needed for a long time.
  3. Treatment should be started now, while there is still a chance for bone remodeling. After 15 years of age, there is a high probability of treatment with surgery.
