<p>PURPOSE:To stably support respective teeth molds by an axial wall and end walls in both ends by providing the end walls rising from the both ends of a substrate, the axial wall rising from the central part of the substrate in the direction of the both ends and plural channels vertically bored on the both side surface of this axial wall. CONSTITUTION:An upper jaw frame 17 is composed of a substrate 21, end walls 22 and 23 rising from the both ends of the substrate, axial wall 24 rising from the central part of the substrate 21 in the direction of the both ends, plural channels 25 and 26 vertically bored on the both side surfaces and cover body 29, for which spaces 28 and 28 for injecting secondary plaster 27 are formed in the both sides of the axial wall 24, to be fitted to the substrate 21 and end walls 22 and 23 freely attachably and detachably. A lower jaw frame 18 is samely composed of a substrate 30, end walls 31 and 32, axial wall 33, plural channels 34 and 35 and cover body 38, for which spaces 37 and 37 are formed for injecting secondary plaster 36, to be fitted to the substrate 30 and end walls 31 and 32 freely attachably and detachably.</p> |
