ABSTRACT:
The present invention comprises an articulator for registering an upper dental cast to a lower dental cast. The articulator includes an upper member subassembly with left and right sides and a lower member subassembly with left and right sides each composed of plastic material. The articulator further has at least one hinge member engaging one of the members allowing one of said members to pivot relative to the other member and a coupling means flexibly connecting the upper member subassembly to the lower member subassembly. The articulator further includes disconnectable connection means joined to one of the members for disengaging the upper member subassembly and the lower member subassembly whereby the upper and the lower member subassemblies may be separated, and a clipping means for removably securing the upper member subassembly to the upper dental cast and the lower member subassembly to the lower dental cast such that said upper and lower dental casts can be properly and flexibly aligned.
