 (000, 00, 0, 1.2, 3)
 and
 must be selected appropriate to the
  gingival tissue, always starting with the
  smaller diameter ..




                           Figure 2
allows the retraction in order to provide:

A space both laterally and vertically between the
gingival margin and gingival termination.

So that the printing material penetrates in sufficient
