摘要： A dental articulator includes an upper frame member and a lower frame member modeled substantially after a maxilla and mandible of a human jaw, respectively. The upper frame member includes a mounting area for attachment of an upper or maxillary dental cast. Two opposing fossae on the upper frame member include downwardly opening sockets similar to the fossae of a human jaw. The lower frame member includes a mounting area for attachment of a lower or mandibular dental cast. Two opposing condyles extend upwardly from the lower frame member to fit within the sockets of the fossae on the upper frame member. An elastic band is placed around the upper and lower frame members to yieldingly maintain the condyles within the sockets of the fossae. Each condyle/fossa pair forms a temporomandibular joint similar to that in a human jaw and allows the lower frame member to undergo protrusive and excursive movements which closely simulate the movement of a human mandible.
