When restoring implants, there are circumstances when it is necessary to splint crowns together. I was recently doing a case on #29 and #30 which required a splinted restoration.
When fabricating this implant bridge, one thinks it is necessary to use a bridge block. In fact, the Mill Phase defaulted to use a 32mm block for the veneering structure (splinted crowns) of this restoration.
However, even though the C14 e.max block has a yellow exclamation, choosing that block in fact indicated that it would likely fit.
We were in fact able to mill this abutment bridge veneering structure out of a C14 block. This is a nice time and cost savings for you. So, next time you are milling a small bridge, try a smaller block like a C14 just in case it might fit!
