1. Influence on craniomaxillofacial development: During the growth and development of children, the normal development of maxillofacial soft and hard tissues is affected by tooth protrusion. If the malocclusion of anterior teeth is not treated in time, the lower dental arch restricts the development of maxilla, while the mandible is overdeveloped, and the upper and lower dental arches are not coordinated, thus forming a 1/3 depression and mandibular protrusion deformity on the face. With the severity of malocclusion, the face is crescent-shaped. Second, it affects the chewing function of the mouth: severe buckteeth can affect the normal function of the mouth, such as abnormal pronunciation caused by the opening of front teeth; Severe mandibular retraction affects normal breathing. Third, it affects the dental health of the oral cavity: Buckteeth are prone to dental caries and gingivitis because they are not easy to self-clean, and often cause periodontal damage due to tooth dislocation. Fourthly, it affects systemic diseases: Buckteeth are not only harmful to the maxillofacial region, but also to the whole body, such as indigestion and gastrointestinal diseases caused by decreased chewing function. In addition, facial deformity will cause serious psychological and mental disorders to patients. Five, affect the appearance: Malocclusion such as buckteeth can affect the appearance, and can present deformities such as lip teeth opening, bimaxillary protrusion, chin up or down, nose deformity, and lip thickness.
