Mandibular retraction, also known as mandibular retraction, is a malocclusion caused by mandibular hypoplasia or congenital loss of lower anterior teeth and dysfunction of lateral pterygoid muscle. Simply put, the symptoms of appearance are short and backward chin, protruding mouth and "bird's mouth" shape on the side.

How to correct mandibular retraction? Is it useful to improve the method of self-sealing breathing after chin retraction?

To tell the truth, if it is in childhood, chin retraction is not serious, nor is it a problem of skeletal chin retraction and protruding mouth. On the one hand, this situation will correct the habit of mouth breathing, and it will improve after breathing with your mouth closed for one year. In addition, the chin retraction caused by oral breathing can be improved by correcting teeth, that is, it is useful to wear braces to improve chin retraction.

Once the skeletal chin retracts, the mandible retracts badly, so it is useless to exercise with your mouth closed or wear braces. Only through medical aesthetic surgery can the correction effect be achieved. Generally, hyaluronic acid injection, prosthesis or chin osteotomy can be used to improve the influence of short chin and chin retraction on face shape. However, these three methods cannot be used in all cases, and they need to be selected according to the chin conditions of the beauty seeker.
