How many adjustment visits does this usually take?
Jaw joint splint

A bite splint made to rest the jaw joint and muscles when the joint clicks, locks or hurts. It looks like a nightguard but is designed and adjusted for the joint rather than for tooth wear.
The splint is made to hold the lower jaw in a position that lets the joint and the muscles rest, and it is adjusted over several visits as things settle. It looks like a nightguard, but the design and the adjusting are aimed at the joint rather than at tooth wear. It is normally one step in a longer plan that can include exercises and other treatment.
