In order to allow positive and quick fixation as well as centric fixation of a condyle portion with a very simplified operation, a semi-adjustable dental articulator is of the construction that an adjusting-and-fixing knob of the adjustable guide plate for the condylar box is provided to protrude beyond the upper surface of the condylar box, and also that an orbita indicator is detachably, semi-fixedly and slidably mounted on the incisal guide pin. On a corner edge line between a back surface and an outer side surface of each of a pair of laterally spaced upright frame portions of an articulator body is provided with an indicator notch aligned with an occlusion plane in height and another indicator notch aligned with an ear in height.
