Abutment is the fulcrum?If so, try heating the abutment with your alcohol torch before putting on the firsf layer of wax. The wax pulls away funny on cold metal and doesn't always stay in the initial design. The more heated the wax is, the worse it will be, so add slowly to the abutment to precent melting all the way to your first/dip layer. How are you taking margins? Do you cut the connectors with monofilament string and rejoin? that can cause the same problem, but the solution is the reverse, use super hot wax and let cappilary action pull it to all the areas after quickly passing your waxknife through the gap. Hope this gives you somrthing to work with that helps. These were the issues that caused my troublez you describe. Your pull-off technique may contribute also, but how you sprue will get you on bridges too. Adding wax till the spruegates are level/even before putting the sprue bar on will reduce the percentage of chance that the wax shrinkage of gate to bar is pulling it out of whack as it can if you add a bunch to one after putting on the others. The more hot wax at one time the greater cooling shrink.Sorry for spelling and style. Tablet giving me fits.Keep getting rocking frame work on pfm 3-7. With intermediate abutment of 5. Any advice?
