Alveolar bone plastic surgery is an outpatient operation of oral surgery. Its purpose is to remove the part that interferes with denture restoration, so that the alveolar ridge can bear occlusal pressure evenly, thus restoring oral and maxillofacial functions such as chewing, language and face. Before alveolar bone plastic surgery, we should pay attention to the following points:

1. A comprehensive oral examination should be conducted before operation to determine the necessity and feasibility of orthodontics.

2. The doctor should be informed of his medical history and allergic history before the operation.

3. Avoid eating hard objects before operation, so as not to affect the operation effect.

4. Pay attention to oral hygiene after operation to avoid infection.
