ABSTRACT:
A dental articulator (10) having a first arch (12) for receiving a dental cast of teeth having a first grid pattern (30) that includes a first plurality of dowel pin holes (60) that define multiple dowel pin locations for receiving a first plurality of dowel pins (34), and a first plurality of support pin holes (62) that define multiple support pin locations for receiving a first plurality of support pins (64) where in the dowel pin locations and the support pin locations are spaced apart such that a die may be held in place within the first arch by one or more of the first plurality of dowel pins and by one or more of the first plurality of support pins to prevent movement or rotation of the die. There is a second arch (14) for receiving a dental cast of teeth having a second grid pattern (32) that includes a second plurality of dowel pin holes (60') that define multiple dowel pin locations for receiving a second plurality of dowel pins (34'), and a second plurality of support pin holes (62') that define multiple support pin locations for receiving a second plurality of support pins (64'), wherein the dowel pin locations and the support pin locations are spaced apart such that a die may be held in place within the second arch by one or more of the second plurality of dowel pins and by one or more of the second plurality of support pins to prevent movement or rotation of the die. The first arch is hingedly connected to the second arch by a hinge connection (40) to allow articulating movement of the first and second arches (12 and 14) with respect to each other.
