    Hi Dr,

    UCSF sent out a manual which says, the axial reduction has to be 0.7 to 1 mm, so the width of the margin created will be 0.7 to 1.0 mm right? I was getting confused with the dimensions of the width as the manual also says that the preparation margin design has to be 0.5mm. I don’t understand what preparation margin design means.

      Margin should be 0.5mm. Because of the cervical constriction, that will allow the axial reduction to be 0.7-1mm. Don’t worry about the axial reduction amount, just worry about the margin width and the angulation of the walls.
