Mandibular retraction cannot usually be restored by self-adjustment. Most of them need extra-pterygoid muscle training, orthodontic treatment, orthognathic surgery and other methods for correction.
1. Extra-pterygoid muscle training: For children with mandibular retraction and distal-medial malocclusion who are less than 10 years old, extra-pterygoid muscle training can be carried out, i.e., protruding the lower teeth to the upper teeth and retaining them on the labial side for 10 seconds, and then retracting them back to the neutral dentition, and repeating the exercise until the muscles get tired. This training has a certain therapeutic effect on children’s mandibular retraction of the distal mesial malocclusion.
2. Orthodontic treatment: For children in growth and development period, functional orthodontic appliances can be used, such as Franke I type orthodontic appliance; for adolescents, fixed orthodontic and intermandibular traction treatment can be used to adjust intermandibular relationship and correct mandibular retraction.
3. Orthognathic surgical treatment: For adults with severe mandibular retraction, orthognathic surgical treatment, such as Let Fort I osteotomy or sagittal split osteotomy of the ascending mandibular branch, can be used to adjust the position of the upper and lower jaws, establish normal dentition and correct mandibular retraction.
People with mandibular retraction should consult an orthodontist in time to complete the examination and choose the appropriate orthodontic method according to the patient’s specific situation.
