A broken lower jawbone that has not healed together, confirmed by imaging such as X-rays or CT scans.
Diagnostic imaging is required for this rating, so records showing an X-ray, CT scan, MRI, PET scan, radionuclide bone scan, or ultrasound that confirms the fracture has not healed are essential. The imaging report should clearly state that the bone ends have not fused.
To support the 30% level, evidence would need to show false motion at the fracture site. Examination findings from a dentist, oral surgeon, or other provider documenting abnormal movement of the jaw at the fracture location would speak directly to that criterion. To support the 10% level, records showing moderate nonunion without that abnormal movement would be relevant.
Your own statements, or statements from people who know you, describing how jaw instability or pain affects eating, speaking, and daily activities can help give VA a full picture of how the condition affects you. Similar statements about how it affects your ability to work may also be relevant.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
