Two-jaw Surgery?
Story Key techniques Surgery Procedures F.A.Q
1. What is the ‘No-tie’ Two-jaw Surgery?
It is a procedure that does not require intermaxillary fixation(IMF) after surgery. Usually the conventional two-jaw surgery required tying the upper and lower teeth together for 2-6 weeks, which is also known as the ‘intermaxillary fixation’. However, the ‘no-tie’ two-jaw surgery eliminates intermaxillary fixation and applies a ‘torque-free’ rigid internal fixation method to let the bones heal and agglutinate quickly.
What is ‘intermaxillary fixation’?

Advantages of ‘No-tie’ Two-jaw Surgery
  More comfort
  • Easy breathing: Intermaxillary fixation causes swelling inside of the nose and difficulty in breathing due to blocking the mouth. The absence of intermaxillary fixation eliminates this pain and allows the patient to breathe comfortably.
  • Enjoy your meals: The patient must eat soft food for a certain period after surgery. In the past, the patient had difficulty chewing food with their teeth tied but the new surgical procedure allows the patient to enjoy their meals without any discomfort in chewing with the mouth open.
  • Easy speaking: Intermaxillary fixation caused difficulty in speaking, but the new procedure allows the patient to speak freely without any pain or discomfort.
  Safe & clean
  • Safe breathing: Intermaxillary fixation causes nasal congestion and other breathing discomfort, which requires families and medical staff to provide intense post-surgical care. This may cause the patient to feel uncomfortable. No-tie two-jaw surgery minimizes this psychological anxiety and eliminates risks of side-effects.
  • Clean oral hygiene: Chewing food with tied teeth caused difficulty in maintaining dental hygiene for the patients. The absence of intermaxillary fixation enables patients to maintain dental hygiene in an easy way.
  Fast recovery to normal daily life.
  • The temporomandibular(TM) joint recovers fast: Intermaxillary fixation usually stiffens the TM joint which requires the patient to practice opening and closing the jaw. But the no-tie two-jaw surgery does not require intermaxillary fixation and does not cause stiffness of the TM joints.
  • Return to daily work faster: Speaking is easy because intermaxillary fixation is not needed, allowing patients to return to work faster.
