Description:

The Homer “Dental Relator” can be classified as a “scribing” articulator. “Scribing” articulators have generally been considered to be those with functionally generated custom guide controls. These articulators have scribing assemblies that usually consist of two to three cup-like receptacles on the lower member with corresponding tracing devices in the form of pins or rods on the upper member. The receptacles are filled with a soft moldable material (usually modeling compound or acrylic resin) and the tracing devices function to displace the soft material before it solidifies. The custom guide paths are generated utilizing a record commonly known as a “functionally generated path” or “chew-in.” The Homer “Dental Relator” was designed with two condylar bearing cups and an incisal elevated bearing cup on the lower member and corresponding and corresponding scribing posts on the upper member. This was Joseph Homer’s third patented “Relator” articulator.

Dr. Edgar N. Starcke's articles in the Journal of Prosthodontics have more information on the history of articulators.
