The offload will be implemented, whatever it is the base. That is, an offload in a tridensity element will be the same that in a monodensity one. Thus, there is a way to work the depth of the offload and fill it in post-production, in your clinic or in the lab (an example for the patient’s file: filling of the offload of the 1 mtt head in the left foot with a shock absorbing material of 4mm and 25 ShA)
