[QUOTE="labguy50, post: 20752, member: 1905"] Whether its a 3 unit or a roundhouse i never ever connect both sides of any pontic until im ready to sprue and invest. Wax it to one of the pontics so that the tolerance is so close that it looks like it is connected..finish waxing the case...add sprues to interproximals, seal the unconnected pontics with G Cera, attach runner bar with sticky wax on one or two sprues..connect the rest with G Cera...when removing from dies use crown holders or tweezers..etc. to gently pry fron the under interproximals while lifting at the same time ....works great at this end ...
