Abstract

Abstract A dental instrument for simultaneously taking an impression and a bite has a pair of parallel elongated bite tray holders which are laterally spaced apart and are connected together at one of their adjoining ends by a connector wire loop. A manipulating handle is fixed to one of the tray holders at the end opposite to its connected end and has an inner fixed leg portion which protrudes from the instrument at a close obtuse angle to pass the lip of a patient and has an integral free outer end portion that extends from the inner end at a sharp angle of at least 90° for easier manipulation beyond the cheek of the patient by an operator. A bite tray is removably and slidably carried by and positioned between the tray holders.
