	Rating
9900Maxilla or mandible, chronic osteomyelitis or osteoradionecrosis of:
Rate as osteomyelitis, chronic under diagnostic code 5000
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
Moderate	10
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:
Not replaceable by prosthesis	40
Replaceable by prosthesis	30
Loss of less than 25 percent:
Not replaceable by prosthesis	20
Replaceable by prosthesis	0
9916Maxilla, malunion or nonunion of:
Severe displacement	30
Code of Federal Regulations 463
Moderate displacement	10
Slight displacement	0
