The Board remands the claim for service connection for temporomandibular joint disorder (TMJ) to obtain a more comprehensive medical opinion.

The Board denied the Veteran's claim for an initial rating greater than 10 percent for temporomandibular joint disorder (TMJ) as the evidence did not show a vertical inter-incisal opening measured between 21 to 29 mm even when considering flare-ups or dietary restrictions.

The Veteran's depressive disorder alone rendered her unable to secure or follow substantially gainful employment, and she is entitled to a TDIU for accrued benefits purposes on and from December 19, 2015. Additionally, the Veteran meets the criteria for SMC based on statutory housebound criteria for accrued benefits purposes.

The Board granted service connection for temporomandibular joint disorder (TMJ) as secondary to posttraumatic stress disorder (PTSD), and granted a 10 percent rating for left hip limitation of extension, while denying other claims.

The Board granted a 50 percent rating for tension headaches and a 50 percent rating for left knee strain, limitation of extension, while denying ratings in excess of 30 percent for TMJ and a compensable rating for alopecia areata. The decision also granted 20 percent ratings for left and right knee strains with limitations on flexion and extension.
