Adjustable Mounting Jig for Mean Value Articulator

Abstract

An articulator is a mechanical instrument that represents the temporomandibular joints and jaws, to which maxillary and mandibular casts may be attached to simulate some or all mandibular movement. During attaching or mounting the casts, problems such as shifting of cast assembly due to compression of modelling stone or waxes. Also shifting of rubberband used for adjusting the occlusal plane during mounting. In addition, errors in transferring maxillo-mandibular relation to articulator are reproduced as errors in tooth relation and tooth movement. This article introduces amethod to overcome these errors and inaccuracies during mounting in mean value articulator adjustable mounting jig.
