[QUOTE="2thm8kr, post: 108020, member: 1367"] Years ago we used to cast lingual fitted bars for patients with heavy bone loss on the lowers to stabilize the teeth. If you are worried about two different investments, use the one that you use for cast metal using the same ratio for expansion for the metal composition you are casting. Trim as much of the refractory investment as possible to keep the weight down. Improvise your spruing technique. [/QUOTE]
