[0002] Double protection telescopic crown denture is a dental restoration device that integrates fixed and removable functions, mainly used for the restoration of missing or damaged teeth. It is mainly composed of two parts: the inner crown and the outer crown. The inner crown is fixed on the abutment, and the outer crown is embedded in the denture. The denture is fixed through the close cooperation of the two. This design not only improves the stability of the denture, but also facilitates daily removal and cleaning. The inner crown is usually made of metal and is directly fixed on the abutment, while the outer crown is closely matched with the inner crown to ensure the stability of the denture.

[0003] In the prior art, during the installation process of telescopic crown dentures, the outer crown is usually installed on the inner crown by utilizing the friction between the inner and outer crowns. However, the outer crown needs to be removed and cleaned regularly. After being removed and installed many times, the friction between the inner and outer crowns will gradually decrease, thereby reducing the stability of the outer crown and making it prone to shaking, reducing the practical life of the telescopic crown denture and affecting the user's normal use.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a double-layer protective telescopic crown denture.

A trapezoidal block 204 is fixed at one end of the connecting rod 203 away from the pressing plate 202, and the trapezoidal block 204 can push the sliding rod 205 to move, thereby pushing the fixed block 206 to move.

[0030] like Figure 1 to Figure 2 As shown, a pair of sliding rods 205 are also slidably connected to the inner crown 201, and the sliding rods 205 are used to support the fixed block 206 and can drive the fixed block 206 to move. The fixed block 206 is fixed on the sliding rod 205, and the fixed block 206 can be supported on the side wall of the groove 207, so as to fix the outer crown 1. A pair of grooves 207 corresponding to the fixed block 206 are cut on the outer crown 1, and the side walls of the grooves 207 can support the fixed block 206.

[0031] like Figures 1 to 3 As shown, a fixing plate 208 is fixed at the lower end of the inner crown 201, and the fixing plate 208 is used to fix the inner crown 201. A fixing block 209 is fixed to the side of the fixing plate 208 away from the groove 207, and the fixing block 209 can be fixed on the abutment, so that the fixing plate 208 and the inner crown 201 can be fixed on the abutment.

[0032] like Figure 1 to Figure 2 As shown, the inner crown 201 has an inner cavity 210, and the inner cavity 210 is used to place the trapezoidal block 204. A first sealing gasket 211 is installed between the inner crown 201 and the pressing plate 202, and the first sealing gasket 211 is used to seal the gap between the pressing plate 202 and the inner crown 201, so that saliva in the oral cavity is not easy to enter the inner cavity 210.
