Claims

[Scope of Claim for Utility Model Registration] (1) An oral mucosal member 2 having elasticity that imitates the vestibule of the oral cavity and the proper oral cavity with the mouth open is firmly fixed and adhered to the jaw bone 1, The oral mucosal member 2 is firmly fixed to the jaw bone material 1 at the gingival region and a part thereof, but is not fixedly fixed at the gingival-buccal transition region 4 and the gingival-labial transition region 5, but is in close contact with the jaw bone material 1, The gingivobuccal transition area 4 and the gingivolabial transition area 5 are freely movable away from the jaw bone 1 and follow the gingivobuccal transition area 4 and the gingivolabial transition area 5 of the oral mucosal member 2. At positions corresponding to the frenulum of the buccal and labial parts, linear members 3 are arranged to suppress movement of the oral mucosal member 2 outward from the dentition in the part where the frenulum is formed. The gingival-buccal transition portion 4 of the oral mucosal member 2 is attached vertically to the jaw bone 1.
A pair of fixed legs 7 are attached to the upper end and/or lower end of the gingival-labial transition part 5 with the linear member 3 in between, and the upper end and/or of the gingival-buccal transition part 4 and the gingival-labial transition part 5 at the above-mentioned attachment position. Or a jaw model for removable denture training, characterized in that vertical movement of the lower end is suppressed. (2) The jaw bone material 1 has the shape of a mandible, and the oral mucosa member 2 on the lingual side of the jaw bone material 1 is formed with a tongue portion 8 having the shape of a tongue;
Furthermore, a movable jig 9 for moving the tongue 8 is provided below the tongue 8, and a gingiva-oral floor transition area 6 which is a transition area between the jaw bone 1 and the tongue 8. is provided with a part where the jaw bone material 1 and the oral mucosa member 2 are fixedly fixed, but in the gingiva-oral floor transition area 6 leading to the tongue part 8, they are not fixedly fixed but are in close contact with each other. The gingival floor transition area 6 is freely movable apart from the jaw bone 1, and the position corresponding to the frenulum of the lingual portion of the oral mucosa member 2 following the gingival floor transition area 6 is provided. , the linear member 3 is attached perpendicularly to the jaw bone material 1 so as to suppress the movement of the oral mucosal member 2 inward from the dentition in the portion where the frenulum is formed; Gingival oral floor transition part 6 of oral mucosal member 2
A pair of fixed legs 7 are attached to the lower end of the gingiva-oral floor transition area 6 with the linear member 3 in between, and the fixing legs 7 are attached to the lower end of the gingiva-oral floor transition part 6 in the vertical direction when the tongue part 8 moves in the vertical direction. The jaw model according to claim 1, wherein movement is suppressed.
