ABSTRACT:
There is disclosed in the present application a series of trays adapted to carrying dental impression medium of varying viscosities on both sides of a thin textile web and between lateral containing walls to permit the taking of impressions of both jaws together in one tray and with the teeth or gums positioned near their normal biting engagement. There is also included in the present disclosure a perforated plate for applying lateral pressure to the medium thereby limiting the thickness of the impression medium and improving the accuracy of that part of the impression taken from the lateral surfaces of teeth.
