Development of Digital Articulator and its Accuracy Verification using Optical Measurement
Abstract. In dentistry, the correct prostheses should be made with the correct occlusion poses. Dentist and dental technician usually design the fixed or removable restorations with mechanical articulators which can simulate mandibular movements and the occlusion to prevent the occlusal interference or other problem. Recently, with the development of dental CAD/CAM systems, commercial software can now digitalize traditional dental workflow and the user can design restorations with higher quality and much less time. However, the occlusion of opposing teeth should be considered for a correct prosthetic design. Therefore, there should be a digital articulator to simulate mandibular movement and occlusion in digital environment. The first articulator in U.S. patent is created by Daniel T. Evens 1840. In 1895, most of researchers considered that there is a condylar path with an inclination and developed average articulators which make condylar ball move with a fixed inclination. In 1899, Snow created facebow to measure the information about human’s skull and transfer that into articulator to make sure the plasters of the upper jaw and the lower jaw are mounted in the correct position.
