The fixed methods of movable denture include abutment covering, setting jaw support, inter-adjacent groove and retaining ring, etc., as follows: a. Abutment covering: Abutment covering in the alveolar ridge, labial and buccal mucosa and hard palate of the missing tooth area, can use the adsorption force between the abutment and mucosa, and the friction force between the edge of the abutment and the teeth to enhance the retention and stability of the denture. Second, set the jaw support: When set the jaw support in the near and far middle of the jaw surface of the teeth, it can stop the denture from swinging back and forth and effectively reduce the food embedment. Third, inter-adjacent grooves and rings: inter-adjacent grooves and rings can play a role in indirect retention, effectively preventing the movable denture from buckling and sinking. The ring arm can produce friction with the tooth surface to prevent the denture from rotating. The tip of the retainer arm can be placed in the inverted concave area to avoid the possibility of lateral displacement of the denture.
