1) Pull on the shorter soaked PVA bag.
2) Tie the PVA bag at both ends and establish a vacuum (see Fig. 14).
3) Heat the PVA bag with a blow drier above the pin receiver so that the
film becomes more rigid (see Fig. 15).
4) Cut off the PVA bag directly above the pin receiver.
5) Tape the resulting opening crosswise with 3 strips of polyethylene
adhesive tape in each direction (see Fig. 16).
6) Cut a cross in the polyethylene adhesive tape above the thread of the pin
receiver (see Fig. 17).
7) Isolate the countersunk head screw of the dummy set with wax.

13) Position a layer of carbon fibre cloth strap medially and laterally from the
lamination disc up to the condyles (see Fig. 21).
14) Anteriorly and posteriorly, attach a layer of carbon fibre cloth strap from
the lamination disc to the circle formed by the carbon fibre cloth strap
(see Fig. 21).
