Irreversible hydrocolloid impression material (Alginoplast, Heraeus Kulzer, GmbH 8 Co Wehrheim, Germany) was used for the mandible (Figure 2, top panel). After completion of border molding (Fig 2, middle panel), the defect area was blocked-out by using gauze impregnated with Vaseline. For the mandible, the border molding and final impression were made by using green compound and zinc oxide-eugenol (ZOE) impression paste (Cavex Outline, Cavex Holland BV; Netherlands), respectively (Figure 2, bottom panel).
