ABSTRACT:
A dental articulator or apparatus is disclosed for testing the accuracy of dentures during occlusion. The articulator is designed to simulate the complex three-dimensional motion of a human jaw and includes a longitudinally-extending base, an upper denture carrier pivotally mounted above the base for movement in a vertical plane, and a lower denture carrier pivotally connected to the base by a bearing-and-slot arrangement that permits three-dimensional curvilinear movement of the lower carrier. By attaching dentures to the carriers and moving the dentures through various centric, eccentric, lateral and protrusive movements against one another, the articulator permits "high spots" on the occlusal surfaces of the dentures to be located so that the dentures can be accurately ground to a proper fitting.
