We reported previously (J. Jpn. Prosthodont. Soc., 30 : 88-99, 1986) on the good results of our high vertical dimension splint (HV-splint) therapy for temporomandibular disorders. In the experimental study, the therapeutic mechanism of HV-splint indicated that condyle traction was obtained by use of this splint. The HV-splint, when set on either the maxilla or the mandible, provides a minimum of 10mm of interocclusal space between the upper and lower first premolars and allows only the molar regions to come in contact during centric relation and eccentric movement. The original articulator however could not be used for fabrication of this splint, because of the need for high interocclusal distance and adjustment of occlusion. We therefore improved the Tsubone's articulator Model MS for fabrication of this splint on the articulator. The improved points were as follows : 1. The bilateral condylar posts and the incisal guide pin were made 50mm longer. 2. The T-attachment of face-bow was also made 50mm longer. 3. The lower mounting plate was made to be adjustable in vertical direction. With use of this articulator, not only fabrication of the HV-splint but also adjustment of occlusion have been made easier.
