Jaw shortening and retraction, medically known as mandibular retraction, is a common clinical malocclusion, mostly due to bad habits, dental irregularities, abnormal jaw development and other etiological factors, which can be corrected by correcting bad habits, wearing functional orthodontic appliances, orthognathic surgery and other methods of correction.
1. Correcting bad habits: During the growth and development of children, long-term finger-sucking, mouth-breathing and other bad habits can lead to excessive development of the upper jaw and underdevelopment of the lower jaw, which is manifested as protruding of the upper jaw and retracting of the lower jaw, and in serious cases, it can be a “bird’s beak-like” deformity. At this time, we should actively correct the children’s finger sucking, mouth breathing and other bad habits.
2. Use of functional orthodontic appliances: mandibular retraction during the period of replacement teeth often needs to lead the lower jaw, adjusting the upper and lower jaw dislocation to the dislocation.
Some functional orthodontic appliances can be used to correct the jaw retraction in the formation by changing the function of orofacial muscles to promote the development of dentition and craniofacial growth. The commonly used orthodontic appliances in the clinic are bimaxillary pads, Andresen orthodontic appliance and Herbst orthodontic appliance.
3. Orthognathic surgery: If the mandibular retraction is a bony deformity and the patient has reached the age of majority, orthognathic surgery can be used to correct the mandibular retraction, and the commonly used surgical procedures include sagittal split osteotomy of the ascending branch of the mandible and horizontal osteotomy of the jaw through intraoral approach.
If you find mandibular retraction, you should consult a doctor in time, complete the examination, make a clear diagnosis, and standardize the treatment under the guidance of a professional doctor, so as to avoid delaying the condition.
