The FGM CoCr Burn-out copings are pieces that fit over the screw-retained intermediate (Abutments for Screw-Retained restoration and Mini Abutments for Screw-Retained restoration) and allow waxing and the preparation of future infrastructure for the prosthetic crown after foundry.
The FGM CoCr burn-out copings are made in two parts, the first is a metal brace, Cobalt-ChromeMolybdenum alloy (CoCrMo) arranged in the cervical portion of the piece, and the second is a polyacetal cylinder (calcinable polymeric material).
