An evaluation of basic articulators and their concepts: Part II. Arbitrary, positional, semi adjustable articulators

Abstract Suggestings have been made for adapting the Hanau Model H articulator for fixed restorative prosthesis. However, the shortcomings of the instrument must be understood. A more adjustable instrument would seem to be indicated in order to reduce the degree of occlusal correction necessary to harmonize biologic movement with the occlusion produced on the articulator. On the basis of the mathematical study, the instrument is of practical value and within the accuracy of the records used for complete denture prosthesis.
