9901Mandible, loss of, complete, between angles 100
9902Mandible, loss of approximately one-half:
Involving temporomandibular articulation 50
Not involving temporomandibular articulation 30
9903Mandible, nonunion of:
Severe 30

Note—Dependent upon degree of motion and relative loss of masticatory function
9904Mandible, malunion of:
Severe displacement 20
Moderate displacement 10
Slight displacement 0
Note—Dependent upon degree of motion and relative loss of masticatory function
9905Temporomandibular articulation, limited motion of:
Inter-incisal range:
0 to 10 mm 40
11 to 20 mm 30
21 to 30 mm 20
31 to 40 mm 10
Range of lateral excursion:
0 to 4 mm 10
Note—Ratings for limited inter-incisal movement shall not be combined with ratings for limited lateral excursion
9906Ramus, loss of whole or part of:
Involving loss of temporomandibular articulation
Bilateral 50
Unilateral 30
Not involving loss of temporomandibular articulation
Bilateral 30
Unilateral 20
9907Ramus, loss of less than one-half the substance of, not involving loss of continuity:
Bilateral 20
Unilateral 10
9908Condyloid process, loss of, one or both sides 30
9909Coronoid process, loss of:
Bilateral 20
Unilateral 10
9911Hard palate, loss of half or more:
Not replaceable by prosthesis 30
Replaceable by prosthesis 10
9912Hard palate, loss of less than half of:
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
Loss of all lower teeth 30
All upper and lower posterior teeth missing 20
All upper and lower anterior teeth missing 20
All upper anterior teeth missing 10
All lower anterior teeth missing 10
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
9914Maxilla, loss of more than half:
Not replaceable by prosthesis 100
Replaceable by prosthesis 50
9915Maxilla, loss of half or less:
Loss of 25 to 50 percent:

Replaceable by prosthesis 30
Loss of less than 25 percent:
Not replaceable by prosthesis 20
Replaceable by prosthesis 0
9916Maxilla, malunion or nonunion of:
