摘要： A temporomandibular joint (TMJ) articulator, capable of simulating common dental occlusion defects, has a maxillary frame on which may be releasably retained a maxillary practice denture, jaw movement guides slidably attached at the left and right sides of the frame, the lower end of each guide having a shaped recess functionally simulating a human TMJ socket, and a mandibular assembly having arcuate left and right jaw plates each bearing a slidably mounted roller and a condyle, the roller and condyle cooperating with the shaped recess to functionally simulate a human TMJ, and the assembly including means for releasably retaining a mandibular practice denture. The articulator is designed to fit within a dental manikin head, especially suitable for student training, which incorporates a solid skull and a flexible face, the face optionally having a tubular waste drain integral therewith.
