[QUOTE="user name, post: 295731, member: 1719"] We arent just considering making the preps parallel so the bridge will draw. The engaging portion of abutments must be able to draw also. If there are multiple implants and one is not close to parallel with the others, imagine screwing long engageing abutments like conical Straumann. Cement the bridge on to it, remove the screws and it wont draw off the model. This is what the OP is considering, I believe. Like SDa36 was saying, you may need to rubber wheel some of the engagement down on a couple. For the Doctor to get them seated accurately though, thats a trick if too much is removed and resulting in non-engagement. The Doctor hasnt thought this through. [/QUOTE]
