Hi, I have a Post and Core on a molar. Dr. Sent the resin pattern with the posts being removable (3) one per root. He will place the core first and then the 3 posts due to the insertion angle they have. Post and Core can not be cast as one piece. My concern is: I am worried the investment would not hold in these small "Post Channels" (very thin). Is there anything I can place inside these post channels while investing to preserve them? I am Casting it with Chrome Cobalt. The wax/resin pattern burnout temperature is 860 C. I will appreciate any thoughts. Thank you.
