A dental articulator of simplified structure, capable of relatively forward and sideward movements to simulate human jaw movements, includes component parts representing lower jaw and maxillary structures held together at simulated condylar joints, wherein spring means press simulated condyles against matching condylar joint walls to hold them in such position when desired and disengaging means are provided which, when actuated, move the spring means away from the associated condyle part, facilitating relative movement of the simulated jaw parts at such joint. When both ends of the spring are moved away from the condyles the jaw portions of the articulator may be separated so that examination of the wear surfaces of dentures held therein may be effected easily. Specifically preferred structural features of the present articulator include a flat spring in strip form, bent at both ends thereof to form anterior condylar joint walls which yieldably hold the simulated maxilla against the condyles, and dog means, near both spring means ends, for selectively moving said spring ends away from the condyles and holding them in such position out of contact with the condyles, and for selectively allowing such spring ends to press against the condyles, as desired.
