Fig. 1. (A) A novel maxillary tray for a simple modified impression method. (left) Not containing an occlusal rim; four-point support may be connected to the occlusal plate, but allowing slight movement of the plate to aid in locating the maxillary anterior teeth. (right) Occlusal plate with applied rim; unlike the conventional occlusal rim, this is designed to be easy to use with a large surface area to record the bite or for gothic arch tracing. (B) A novel mandibular tray for a simple modified impression method. (left) Occlusal view, (right) lateral view of both the novel maxillary and mandibular trays; the closed-mouth technique is performed by biting the maxillary occlusal plate and the mandibular anterior short occlusal rim using the bimanual method. The plate and mandibular occlusal rim have indentations so that the silicone bite registration material is precisely positioned between the two trays.
