Abstract
Dental articulators are designed to emulate the maxillo-mandibular complex in man. It is presumed that the more closely an articulator resembles the maxilla-mandibular and TMJ complex, the more likely it will accurately reproduce mandibular movement of the human. Most contemporary articulators use a ball to simulate the mandibular condyle and a flat plane to simulate the articular eminence. This particular design only allows for one axis of rotation along one linear path of translation. The Polycentric Hinge Articulator (POLY) features a cylindrically shaped condyle and a trough shaped articular fossa and eminence, which, anatomically, is more similar to man. This design is purported to provide for multiple rotational axes and continual change of these rotational axes along non-linear curved translation pathways. These axes of rotation and translation pathways are personalized for each individual on the POLY by adjusting the media-lateral condylar angulation and intercondylar distance. Based on these concepts, the designers of the POLY believe their articulator more closely replicates movement of the human mandible. The purpose of this study was to compare right and left lateral movements on the POLY and SAM 2 articulators to those same movements in the human subjects. Twenty asymptomatic adult subjects consisting of eleven males and nine females volunteered to participate in this study at Marquette University, Milwaukee, WI...
