Introduction
Generally, the maxilla begins to grow and develop simultaneously with other organs after a newborn's birth. During the growth and development process of the jaw, girls typically enter a rapid growth phase at 9–10 years of age, while boys enter this phase at 12–13 years of age. The maxilla usually stops developing by the age of 18. In daily life, self-protection is important, and high-intensity physical activities should be avoided as much as possible.
Under normal circumstances, the maxilla stops developing at around 18 years of age. The specific details are as follows:
Generally, after birth, the maxilla begins to grow and develop simultaneously with other organs throughout the body. During the growth and development process of the jawbone, girls typically enter a rapid growth phase between 9 and 10 years of age, while boys enter this phase between 12 and 13 years of age. The maxilla usually stops developing by approximately 18 years of age.
It should be noted that developmental abnormalities of the maxilla may occur, which can manifest as a blunt mandibular angle, elongated mandibular body, short mandibular ramus, or underdevelopment of the upper jaw. If the maxillary deformity is caused by dental factors, partial teeth may be extracted followed by orthodontic treatment for correction. However, if the protrusion of the jawbone results from abnormal skeletal development, surgical intervention is required to correct the craniofacial deformity. During surgery, the jawbone is cut, excess bone is removed, and then the maxilla is repositioned to its original location and fixed internally. Surgical treatment is generally recommended after the maxilla has stopped growing at around 18 years of age for optimal outcomes.
In daily life, individuals should pay attention to self-protection and avoid high-intensity physical activities or risky behaviors such as unregulated rock climbing or street racing, to prevent adverse effects on health.
