Notes on early dental articulators:
An articulator is a mechanical device used in dentistry to which casts of the maxillary (upper) and mandibular (lower) teeth are fixed, reproducing recorded positions of the mandible in relation to the maxilla. An articulator assists in the fabrication of removable prosthodontic appliances (dentures), fixed prosthodontic restorations (crowns, bridges, inlays and onlays) and orthodontic appliances.
In 1840 the first US patent for dental articulators were issued to two Philadelphia, Pa dentist: James Cameron, and Daniley T. Evens. One glaring weakness that became evident shortly after its release was its inability to manage mandibular movement. Through the 1850s and 1860s dental scientist investigated the nature of mandibular movement. By the 1900s the single hinge dental articulators became commonplace. It wasn't until 1910 that dentistry had its first articulator breakthrough due to the work of scientist like W.E. Walker, Alfred Gysi and George Snow. From their work two major schools of articulators developed. On one side there was the new condylar (anatomic) movement and on the other side there was the geometric (non-anatomic) movement.
