It will have an impact, because the alveolar cleft of cleft lip and palate is the gum interruption caused by alveolar bone defect. After the cleft lip, the teeth around the cleft lip can't erupt normally. It is very difficult to align the teeth through orthodontic movement, because the stability of the teeth needs the support of alveolar bone. If the tooth moves to the position of alveolar cleft, the tooth may loosen and fall off due to the defect of alveolar bone.

The purpose of repairing alveolar cleft is to restore the continuity of maxillary dental arch and provide bone support for the teeth that have not erupted near the cleft.

The repair of alveolar cleft also plays an important role in the nasal and lip morphology of patients with cleft lip and palate.

Repair of alveolar cleft is also to close soft tissue cracks such as oronasal fistula and provide a stable support for supporting the bottom of lip and nose.

In addition, alveolar cleft has a great influence on a person's appearance. Maybe everyone can't see him when he closes his mouth, but his heart must be anxious and inferior, and all the pain is borne by himself. In addition to appearance, it is more important to have a negative impact on the physiology of patients.
