Technique for fabrication of centric relation-based occlusal splint with central bearing device

This study presents a technique for constructing an occlusal appliance. The central relation position must be located with Gothic arch registration. A central bearing post is fixed to the upper vacuum-adapted sheet and a registration plate is made for the lower cast. For the eccentric guidance construction, a prefabricated guiding ramp is secured just behind the most anterior point of the Gothic arch. The eccentric guidances, which harmonize with condylar movements, are printed by the mandibular canines on the surface of the self-curing resin as the post slides on the inclined surface of the ramp.
