A dental impression alignment guide comprising a frame which holds a conventional dental impression compound tray on one end and a laser source on the other end. The laser beam is split into two orthogonal fan shaped beams that project vertical and horizontal lines on the face of a patient. The lines are fixedly coupled to the impression compound tray, thus indicate the tray's position in the patient's mouth. The use of the alignment measuring tool facilitates the alignment of subsequent dentures in the articulated artificial jaw dentists use to verify fit and occlusion before moving dentures, appliances, or surgical procedures to the patient.
