    Longer span frameworks and those with a significant curve to them should have a support structure that would be left in place during sintering. This will help to stabilize them. You would then remove the support after sintering with a diamond disk and water. I would then do a regeneration firing before applying porcelain.

Hardly ever happens with frameworks with no curve, but seems to be more frequent with 4 unit and larger frames that curve (anterior). Individual units fit terrific internally and marginally, but 2-3 out of 10 times the frames will rock slightly....
