The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.WO 2014/037778 PCT/IB2013/001832 1/15 102 110 100 100 100a 100b 100c10d 112 FIG. 1A FIG. 1B 120 100 122 FIG.
