I have braces and recently went into a Closed Lock. How will my ortho unlock me?

I had braces as a teenager and bicuspids removed. This resulted in clicking popping and locking. Im now 51 with braces put on by a TMJ ortho 2 1/2 years ago. He moved my upper arch forward and out but one month before removal of braces, my disc fell and I went into Closed Lock and he has not yet recaptured it. He has dental blocks on my back molars and a bite appliance to keep me from clenching . I can open to 2 fingers. I'm worried that he will not be able to recapture the disc.
