§ 4.150 Schedule of ratings - dental and oral conditions.

	Rating
Note (1): For VA compensation purposes, diagnostic imaging studies include, but are not limited to, conventional radiography (X-ray), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), radionuclide bone scanning, or ultrasonography
Note (2): Separately evaluate loss of vocal articulation, loss of smell, loss of taste, neurological impairment, respiratory dysfunction, and other impairments under the appropriate diagnostic code and combine under § 4.25 for each separately rated condition
9900 Maxilla or mandible, chronic osteomyelitis, osteonecrosis or osteoradionecrosis of:
Rate as osteomyelitis, chronic under diagnostic code 5000.
9901 Mandible, loss of, complete, between angles	100
9902 Mandible, loss of, including ramus, unilaterally or bilaterally:
Loss of one-half or more,
Involving temporomandibular articulation
Not replaceable by prosthesis	70
Replaceable by prosthesis	50
Not involving temporomandibular articulation.
Not replaceable by prosthesis	40
Replaceable by prosthesis	30
Loss of less than one-half,
Involving temporomandibular articulation.
Not replaceable by prosthesis	70
Replaceable by prosthesis	50
Not involving temporomandibular articulation.
Not replaceable by prosthesis	20
Replaceable by prosthesis	10
9903 Mandible, nonunion of, confirmed by diagnostic imaging studies:
Severe, with false motion	30
Moderate, without false motion	10
9904 Mandible, malunion of:
Displacement, causing severe anterior or posterior open bite	20
Displacement, causing moderate anterior or posterior open bite	10
Displacement, not causing anterior or posterior open bite	0
9905 Temporomandibular disorder (TMD):
Interincisal range:
0 to 10 millimeters (mm) of maximum unassisted vertical opening.
With dietary restrictions to all mechanically altered foods	50
Without dietary restrictions to mechanically altered foods	40
11 to 20 mm of maximum unassisted vertical opening.
With dietary restrictions to all mechanically altered foods	40
Without dietary restrictions to mechanically altered foods	30
21 to 29 mm of maximum unassisted vertical opening.
With dietary restrictions to full liquid and pureed foods	40
With dietary restrictions to soft and semi-solid foods	30
Without dietary restrictions to mechanically altered foods	20
30 to 34 mm of maximum unassisted vertical opening.
With dietary restrictions to full liquid and pureed foods	30
With dietary restrictions to soft and semi-solid foods	20
Without dietary restrictions to mechanically altered foods	10
Lateral excursion range of motion:
0 to 4 mm	10
Note (1): Ratings for limited interincisal movement shall not be combined with ratings for limited lateral excursion
Note (2): For VA compensation purposes, the normal maximum unassisted range of vertical jaw opening is from 35 to 50 mm
Note (3): For VA compensation purposes, mechanically altered foods are defined as altered by blending, chopping, grinding or mashing so that they are easy to chew and swallow. There are four levels of mechanically altered foods: full liquid, puree, soft, and semisolid foods. To warrant elevation based on mechanically altered foods, the use of texture-modified diets must be recorded or verified by a physician
9908 Condyloid process, loss of, one or both sides	30
9909 Coronoid process, loss of:
Bilateral	20
Unilateral	10
9911 Hard palate, loss of:
Loss of half or more, not replaceable by prosthesis	30
Loss of less than half, not replaceable by prosthesis	20
Loss of half or more, replaceable by prosthesis	10
Loss of less than half, replaceable by prosthesis	0
9913 Teeth, 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
9914 Maxilla, loss of more than half:
Not replaceable by prosthesis	100
Replaceable by prosthesis	50
9915 Maxilla, 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
9916 Maxilla, malunion or nonunion of:
Nonunion,
With false motion	30
Without false motion	10
Malunion,
With displacement, causing severe anterior or posterior open bite	30
With displacement, causing moderate anterior or posterior open bite	10
With displacement, causing mild anterior or posterior open bite	0
Note: For VA compensation purposes, the severity of maxillary nonunion is dependent upon the degree of abnormal mobility of maxilla fragments following treatment (i.e., presence or absence of false motion), and maxillary nonunion must be confirmed by diagnostic imaging studies
9917 Neoplasm, hard and soft tissue, benign:
Rate as loss of supporting structures (bone or teeth) and/or functional impairment due to scarring.
9918 Neoplasm, hard and soft tissue, malignant	100
Note: A rating of 100 percent shall continue beyond the cessation of any surgical, radiation, antineoplastic chemotherapy or other therapeutic procedure. Six months after discontinuance of such treatment, the appropriate disability rating shall be determined by mandatory VA examination. Any change in evaluation based upon that or any subsequent examination shall be subject to the provisions of § 3.105(e) of this chapter. If there has been no local recurrence or metastasis, rate on residuals such as loss of supporting structures (bone or teeth) and/or functional impairment due to scarring
