The Scott system of precision articulation in three-dimensional occlusion

Abstract

Summarizing, there are seven pieces of equipment for chair work, namely, (1) the face meter; (2) the face-bow; (3) the bite leveller; (4) the nose cuspid meter; (5) the Gothic arch tracer; (6) the sagittal marker, and (7) the rotary point finder; and three pieces of laboratory equipment, (1) the template; (2) the articulator, and (3) the milling machine. The technique embraces three-dimensional occlusion. The principle applied to registration of occlusion on the articulator is the mandibular movement, as in the human jaw. The cusp-type tooth is used. From the first examination to the delivery of the dentures, only three sittings are required. The system attacks the problem from the therapeutic standpoint by providing proper exercise of the oral structures by providing equalized pressure in point-to-point contacts of every tooth in the dental arch. The principle embodied in the process simulates the natural laws of the oral anatomy. It provides a masticating mechanism that moves absolutely free and frictionless at all points of cusp contact, anteriorly and posteriorly and in the alternate lateral strokes.
