2, bony protrusion and buckteeth: due to the overgrowth of the maxilla or the retraction of the mandible, the effect of wearing braces in this case is not good, it is recommended not to do it, and surgery is needed.
3. Mixed protrusion and buck teeth: There are some dental factors and some skeletal factors. Such patients can also wear braces, but the effect is greatly reduced. Braces improve the teeth, but have no effect on the bone factors.
As can be seen from the above, skeletal buck teeth can not be corrected by wearing braces, because the growth and development have stopped at this time, and the speed of bone metabolism and alveolar bone remodeling is relatively slow. Brace correction can only aim at odontoid buckteeth and help them arrange their teeth neatly, but it has no effect on odontoid symptoms.
Surgical orthodontics can be used to correct bony buckteeth, directly adjust the relationship between teeth and jaw by opening alveolar bone, restore the normal occlusal relationship of anterior teeth, change the symptoms of full mouth protrusion and improve the beauty of patients.
