<p>PURPOSE: To make it possible to uniformly and tightly adhere the base plate surface of gnathic models and O-ring mounting means by disposing a plurality of O-rings and covering all the O-rings with the base plate surface of this model. CONSTITUTION: This mode includes the maxillary model 2 mounted at an upper supporting plate 4 and the mandibular model 3 mounted at a lower supporting plate 5. The two supporting plates 4, 5 have the O-ring mounting means 8 on their inner flanks facing the denture for the purpose of mounting the gnathic models 2, 3. The O-ring mounting means 8 have a plurality of O-rings 10 disposed apart from each other. Clamping means 9 extend into the supporting plates 4, 5 and the pedestal surfaces 16 of the gnathic models 2, 3 are fixed to the mounting means 8 by utilizing the same. As a result, the base plate surface 16 is always uniformly and tightly adhered to the O-ring mounting devices 8 when the gnathic models 2, 3 are held and clamped.</p> |
