Preparation for surgery

S'OS > Services > Orthognathic surgery > Preparation for surgery

(Orthodontic treatment – ORTO-3)

At this stage of treatment, orthodontic treatment is applied to the patient, in which orthodontist and maxillofacial surgeon take part. The objective of orthodontic preparation, according to the treatment plan compiled by the doctor-surgeon, is to align teeth into normal arches matching each other. It is a mandatory condition to be met, aiming to perform orthognathic surgery.

The course of treatment:

  • All molars are removed before the start of orthognathic treatment or at its beginning.
  • It could be that the extraction of two or four healthy teeth will be necessary because of a substantial mismatch between the sizes of dental arches or crowded teeth.
  • For 12-18 months before the surgery, the patient wears braces on the upper and lower teeth. The objective of orthodontic preparation is to align teeth into regular arches matching each other according to the treatment plan compiled by the doctor-surgeon.
  • The preparation of the patient happens in I-2 weeks before surgery. At that time, orthodontic treatment is already completed, and the teeth can longer be moved with braces. All preparative diagnostic tests and actions are carried out by the surgeon because he is responsible for the post-operative result, and precision of the surgery.
  • The patient arrives at the hospital for planned orthognathic surgery. He/she must be healthy and not sick with any infections of the respiratory tract for 2-3 weeks before the surgery.
  • After the surgery, when the jaws have healed completely, the final orthognathic treatment takes place, and it lasts for 6 to 12 months.

It is important to remember:

One week before the surgery, the following laboratory tests must be carried out:

  1. Essential blood test
  2. Bleeding and coagulation time, SPA, INR, APTT
  3. Blood group and Rhesus factor
  4. Biochemical blood test (K, Na, Ca, urea, creatinine, fibrinogen, AST, ALT)
  5. Electrocardiogram with description
  6. Urea test
  7. A chest radiograph (if it was not taken in recent years)

Results of tests are to be brought to consultation with a surgeon before the surgery and to examination with doctor anesthesiologist.
