How severe is her TMD? What are her TMD symptoms? Where is her optimal "resting" bite position? Though made out of a hard material, are the Invisalign trays really thick enough to maintain a proper bite, and does the dental professional have the technology to ensure that she is addressing these issues? Nobody wants to hear the obligatory "I don't know..." but, it's true, there's too many unknowns to attempt to answer this question without a more thorough understand of her condition.
