[QUOTE="Beatrice, post: 327658, member: 1017"] Scanning the analog directly will obviously include this kind of problem where the analog can be damaged (not uncommon) thing said, people use new analog more often vs scanbody that get used and worn and few lab think about replacing them frequently. Adding scanbody will ALWAYS result in lost of precision, will it be enough to void all possible "passive fit" ? well it depend! It not an easy question to answer, majority of cases scanbody will do great, some implant connection (read any taper implants) are much harder to scan vs flat seating (read Nobel Multi-unit) But as the analog, scanbody come in different quality and lost precision with time, and contrary to believing, if your analog is damaged, putting a scanbody on top of it do not solve the problem, it makes it worst! It hard to explain using only words, but I do have in some presentation I give multiple example of why a scanbody on top of a damaged analog will decrease the fit of your structure. So in simple, scanbody required to check 2 pieces : analog and scanbody,! Scanning direct analogs 1 piece : analog. Hope it help, but I understand it might not be a complete answer, next time you have the opportunity to assist one of my lecture in different trade show around USA (sorry i take that you probably from USA, hope I am not mistaken :) stop by and you will see why.
