I was going to post on Bobby Talk or other places, but there were a lot of really bad people, so I'm writing a review here, the last to join . I looked at hospitals to lower the line while the tooth was loosened , but if the existing thread on the loose side closes its eyes, it will show. I was worried about what to do if I couldn't find it while looking for it at another hospital, so I ended up removing the existing thread at the hospital that only removed it after much deliberation. I lowered the coalescing buried line by 2mm with the existing thread removed. I'll do a review and post it during the recovery period! I've been to the 7th army in the hospital.
