That is really interesting. My prosthodontist had told me to sleep with it out at night, so that is what I have been doing ever since the week after surgery, when they removed the screws. It does seem like such a relief at night to take it out, and I sleep fairly well, but boy do I dread having to go through that every morning. I think I will give it a try and keep it in all night and see how I sleep. Any word when they will start fitting you with the permanent obturator?
