Expedited Record Base Fabrication Using an Irreversible Hydrocolloid Cast

The registration of a maxillomandibular relationship requires additional clinical and laboratory procedures when the mouth presents with loss of occlusal support. This procedure can be a challenge for a patient who needs urgent care or resides in a remote area. This article describes a procedure for expediting the mounting of a master cast for the fabrication of a maxillary immediate complete denture. The technique presented describes the use of a silicone record base made on an irreversible hydrocolloid cast generated from the final impression.
