[QUOTE="Baobabtree, post: 199392, member: 12298"] I've had this before and I didn't have enough exposed alloy to allow cooling. Drove me nuts, and this was well before DLN. Where possible I design in metal backings if bite doesn't allow porcelain coverage and collars in the cingulum areas or intersticially of the pontics. If your doc doesn't like exposed alloy then perhaps suggest doing it in Zr. [/QUOTE]
