Maxillofacial development refers to the growth and formation of the maxilla (upper jaw) and mandible (lower jaw), along with the surrounding facial structures. This process begins in the early stages of embryonic development and continues through childhood and adolescence. Proper maxillofacial development is crucial for functional aspects like chewing and speaking, as well as for aesthetic appearance. Factors influencing maxillofacial development include genetics, nutrition, and environmental influences. Abnormalities in this development can lead to conditions such as cleft lip and cleft palate, which may require surgical intervention. Understanding these processes is essential for orthodontics and oral surgery.
