Extracted tooth alveolar bone protrusion can be given compression resorption or surgical treatment depending on the size of the protrusion. The main reasons for alveolar bone protrusion during tooth extraction are: excessive damage during tooth extraction surgery or fracture of the alveolar bone; tooth extraction surgery is carried out in phases, the amount of alveolar bone resorption varies; a number of teeth are extracted at the same time and the alveolar bone resorption rate is different, or the alveolar ridge is not uniformly high or low; tooth infection destroys the alveolar bone before tooth extraction or periodontal disease causes different degrees of alveolar bone atrophy, etc. If the alveolar bone protrusion is small, it can be absorbed by pressing down on it so that it will be absorbed after rubbing down. If the alveolar bone protrusion is small, the alveolar bone can be rubbed down and absorbed by pressing the alveolar bone so that it is compressed. If the protruding area is large, it is generally impossible to absorb it by pressing or rubbing it. Those who have protruding alveolar bone that will affect future restoration should undergo alveolar ridge revision immediately. Alveolar ridge revision surgery is a method of eliminating irregular bone or soft tissues such as cusps and sharp edges on the alveolar ridge of missing teeth. After the extraction of the alveolar bone protrusion should be standardized treatment under the guidance of the doctor.
