[QUOTE="BobCDT, post: 183307, member: 3119"] I'm pretty sure its' the spruing. You don't want the glass flowing in and hitting the prep at a right angle. The spru needs to be setup so the glass flows across the buccal cavity and goes around the prep. Another way to describe it, have the prue almost parallel and almost flush to the buccal surface rater than aligning through the interproximal contact. [/QUOTE]
