Paul,
I had to fight for 5 months with the insurance to get the Dynasplint. I wrote 3 letters and it finally went to an emergeny appeal. The insurance is renting the device, for 5 months. If they rent it for 7 months it is paid for in full. I hated the wooden sticks. Trismus is bad, and mine would get worse almost overnight, stay the same, and then get worse a few weeks later. My goal is to do 90 minutes a day on the dynasplint, so far I am up to 60 minutes. It hurts, almost as much as the sticks, but seems more sanatary and is helping (so far) at least some.
