Not replaceable by prosthesis | 20 |
Replaceable by prosthesis | 0 |
9913Teeth, loss of, due to loss of substance of body of maxilla or mandible without loss of continuity: | |
Where the lost masticatory surface cannot be restored by suitable prosthesis: | |
Loss of all teeth | 40 |
Loss of all upper teeth | 30 |

All upper and lower teeth on one side missing | 10 |
Where the loss of masticatory surface can be restored by suitable prosthesis | 0 |
Note—These ratings apply only to bone loss through trauma or disease such as osteomyelitis, and not to the loss of the alveolar process as a result of periodontal disease, since such loss is not considered disabling | |
