# Intraoral Immi Obturator

It is a base plate appliance which is constructed from the preoperative impression cast and inserted at the timeof resection of the maxilla in the operating room. The surgical obturator provides a matrix on which the surgical packing can be placed. It maintains the packing in the proper relationship, thus ensuring close adaptation of the skin graft. It also reduces oral contamination of the wound during the immediate postsurgical period and may thus reduce the incidence of local infection, and the nasogastric tube maybe removed at an earlier date.
