#### § 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 | |

| 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 | |
