With every software release it seems that the form tools work slightly differently. Existing users will make comments that the Smooth Tool is more aggressive or less aggressive than in previous versions. Some users are happy. Some will complain. 

With CEREC Chairside Software v.4.3, Sirona has found a way to satisfy everyone. The three Form tools; Form (+), Form (-), and Smooth are now fully adjustable. As always, the user can control the size of the area to be affected. But now the intensity, or strength, of the action is also fully customized. Simply scroll to set the strength to your liking. It will now remain at this setting for this and all future cases.
