Orthodontic treatment from the back side of teeth

Orthodontic treatment from the back side of teeth

Orthodontic device from the back side

The orthodontics from the back side is the best way for the patients who cannot wear the device due to work. About one third of the entire patients at our clinic request the treatment from the back side.
Comparing the treatment from the front and back, advantages and disadvantages are explained as follows.

Advantages:

  1. The orthodontic treatment can be done without being noticed by someone.
  2. The tooth decay cannot be caused easily. The back side of teeth has more saliva gland, and is always clean compared to the front side, so it can be said that the tooth decay can be avoided easily.
  3. The front side of teeth stays intact.

Disadvantages:

  1. Certain sounds starting with "sa" and "ta" cannot be pronounced easily. Will get used to a month or so.
  2. The device for upper front teeth contacts to the lower front teeth, so it is difficult to bite by back teeth. (About 3 to 4 months)
  3. Hard to brush on the back side of teeth.
  4. The tongue feels uncomfortable, and it may hurt.
  5. Expenses are high.
  6. The treatment period may take longer.

The treatment costs which you are most concerned about.

  • It costs about 1.2 to 1.5 times of the cost compared to the front side treatment. It is the initial technical charge for the orthodontics from the back side of teeth.
  • The most important thing for the back side of teeth treatment is how to place the bracket to the correct spot. Configuration of the back side of teeth differs depending on the patients rather than the front side, so it is difficult for the physicians to place the device directly to the teeth. In addition, it is said that good quality of treatment depends on situating the initial bracket.

The procedures for the good quality treatment from the back side of teeth for each patient are as follows.

Condition of the mouth at the first diagnosis

  1. Replication of the correct teeth alignment model
  2. Dental laboratory
    The set up model to simulate the ideal condition of teeth alignment is replicated.

  3. Clinic
    Detailed check-up of the simulation model.
  4. Dental laboratory
    Positioning the bracket to replicate the condition. Making a core to accord with each tooth for the clients to wear correctly.
  5. Clinic
    Fixing the core including the bracket made at the dental laboratory to each tooth of the patient. The orthodontic treatment is started after fixing the wire.
    The condition of mouth after the treatment

    Depending on the patients, at first the following device is prepared to move the teeth roughly, then the bracket will be set up.

Up to this process, the technical charge is added to the orthodontics cost which is not required for the front side of teeth treatment.


About the treatment period and result

There is no difference from the front side teeth treatment if the physician is an expert for the back side teeth treatment.

Difficult cases from the back side

  • Most of back teeth are missing.
  • Short and grounded down teeth
  • Long face with the lower jaw being rotating downward and backward

If the finishing from the back side is not under control, the treatment may be done from the front side with the device for the last few months upon the patient's approval. This will target on 100% finishing.
