Abstract
The movable false tooth has wide application range, unfortunately, the installation is not firm enough, and the using effect is unsatisfactory. The false tooth needs to be ground, and when the false tooth needs to be treated, the false tooth needs to be removed and remade. The invention has three structures, and the three structures are firmly arranged on the real teeth on two sides by the clamping force generated by the self structure, and the firmness degree of the three structures is comparable to that of the fixed false tooth. In the first structure, two hooks are arranged in the inner cavity of the shell, and when the two hooks are hooked, the two ends of the shell are precisely attached to the real teeth and the false tooth shell is firmly arranged on the real teeth at the two sides. The second structure is divided into an outer sheet and an inner sheet, both ends of which are closely attached to the outer surface and the inner surface of the two side real teeth, respectively, and they are connected with each other by screws. The third structure is that the adjusting column and the ejector rod are embedded in the false tooth body to form a fixed mechanism of the false tooth, the adjusting column enlarges the eccentric ejector rod, so that the ejector rod can prop against the true tooth with proper force, and the false tooth is installed.

The specific embodiment is as follows:
the artificial tooth is firmly arranged on the real teeth on two sides by the clamping force generated by the structure of the artificial tooth, and the firmness degree of the artificial tooth is comparable to that of the fixed artificial tooth.
The present invention has three configurations.
The first structure is shown in figures 1 to 4, the false tooth shell is divided into an outer plate 4, an inner plate 3 and a middle plate 7 in figure 1, the outer plate 4, the inner plate 3 and the middle plate are made of the same metal thin plate, a long hook 1 is welded on the outer plate 4 in an inner cavity 5 of the shell, a short hook 2 is welded on the inner plate 3, when the two hooks are hooked, two ends of the shell are precisely attached to real teeth 8, the false tooth shell is firmly installed on the real teeth 8 on two sides, and when the two hooks are separated, the false tooth can be conveniently detached. The inner cavity 5 of the shell is filled with soft silica gel, the volume of the inner cavity is just full of the inner cavity of the shell during installation and is precisely attached to the gum, the free shape of the inner cavity is the same as that of the inner cavity of the shell during detachment, and the silica gel surface lines 17 in the figures 1 and 3 show different states of the silica gel when the denture shell is installed and detached. In order to assemble and disassemble the denture shell, the invention designs a special pliers, and the special pliers are shown in figure 3: the forceps comprise an inner forceps 11 and an outer forceps mouth 12, wherein the two forceps mouths are respectively provided with a handle 15, and the two forceps mouths are hinged through a pin 13. The front end of the inner forceps mouth 11 is provided with a hook 10, and the front end of the outer forceps mouth 12 is provided with a soft pad 14. When the artificial tooth shell is installed, the artificial tooth is firstly placed in place, the front end hook 10 of the inner forceps mouth 11 is contacted with the upper edge opening of the inner sheet 3, the front end cushion 14 of the outer forceps mouth 12 is contacted with the junction of the lower edge of the outer sheet 4 and the middle sheet 7, the handle 15 is tightly held and then slightly swings clockwise, the long hook 1 and the short hook 2 are hooked, the two ends of the outer sheet 4 and the inner sheet 3 are precisely attached to the real teeth 8, and therefore the artificial tooth shell is firmly installed on the real teeth 8 on the two sides. When the false tooth is dismounted, the hook 10 at the front end of the inner forceps mouth 11 is contacted with the upper edge of the inner sheet 3, the cushion 14 at the front end of the outer forceps mouth 12 is contacted with the junction of the lower edge of the outer sheet 4 and the middle sheet 7, the handle 15 is held tightly and then swings anticlockwise slightly, so that the long hooks 3 and the short hooks 2 are separated, the two ends of the outer sheet 4 and the inner sheet 3 are separated from the real teeth 8, and the false tooth shell can be dismounted.
The second configuration is shown in fig. 5-7: the artificial tooth is divided into an outer plate 28 and an inner plate 27, both ends of which are closely attached to the outer and inner surfaces of the two real teeth 24, respectively, and they are connected to each other by screws 26, and the clamping force of the screws 26 to the real teeth 24 can be adjusted.
In order to increase the strength of the outer and inner sheets 28 and 27, the reinforcing ribs 22 are provided in their bodies, and are formed of two substantially parallel flat wires, as shown in fig. 7, with both ends bent in the width direction toward each other and folded together, leaving a gap 29 in the middle, and when the reinforcing ribs are embedded in the resin-made prosthesis body, the gap 29 is filled with resin, which gives consideration to the integrity of the prosthesis body while providing the reinforcing ribs 22.
The width of the gap 29 is equal to the thread root diameter of the screw 26, and the two flat wires are offset by half a pitch in the thickness direction, and these two designs enable the reinforcing rib 22 to be embedded in the thread groove, and bear most of the tightening force of the screw 26, so that the internal thread of the resin material does not slip.
The screw 26 is a tapping screw with a hexagon socket head, the tapping screw has narrow threads and wide screw grooves, so that the internal threads of the tooth body are stronger, and the hexagon socket head is convenient for adjusting the clamping force of the screw 26.
In order to adjust the clamping force of the screw 26 in the mounting state of the denture, the invention designs a special inner hexagonal wrench, as shown in figure 8 and figure 9, a hexagonal steel bar 34 is fixed at the center of a circular sheet 32 with a groove on the circumference, a clamping ring 31 with two bent feet 35 is arranged on the periphery of the groove, and the inner circumference of the clamping ring 31 is movably matched with the circumference of the bottom of the groove of the circular sheet 32.
When the false tooth in the installation state needs to be adjusted, the bent foot 35 is held by one hand, the mouth is opened, the head of the hexagonal steel rod 34 is inserted into the hexagon socket head of the screw 26, the wafer 32 is pressed by one finger of the other hand, the finger holding the bent foot 35 is tightly held, the screw 26 can be screwed by pulling, the finger holding the bent foot 35 is loosened and swung back, the wrench returns, the pulling is loosened, and the clamping force of the screw 26 can be adjusted to the optimal state.
Between the outer sheet 28 and the inner sheet 27 is a layer of soft silicone gel 25, which serves to prevent food from becoming trapped between the outer and inner sheets.
Fig. 10-12 show a third configuration of a denture: the adjustment post 44 and the post rod 46 are embedded in the denture body 43, and constitute a denture fixing mechanism. The adjusting column 44 is erected in the false tooth body 43 and is in close movable fit with the false tooth body 43, and the middle of the upper section of the adjusting column is provided with an eccentric column 42 which is formed by cutting a gap 41 in the adjusting column 44; on the same plane with the gap 41, an ejector rod 46 is arranged from the gap 41 to the edge opening of the false tooth body 43, and is in close movable fit with the false tooth body 43 like the adjusting column 44, so that when the adjusting column 44 rotates, the eccentric column 42 can push the ejector rod 46 to extend outwards, before the false tooth is installed, the adjusting column 44 is rotated to the minimum eccentricity, the ejector rod 46 is pushed into the false tooth body 43, the mouth is opened, the false tooth is installed in place, then the adjusting column 44 is rotated by an internal hexagonal wrench, the eccentric column 42 is enlarged to push the ejector rod 46 eccentrically, the ejector rod 46 is abutted against the real tooth 47 with proper force, and the false tooth installation is completed.
The dentures with the three structures can be externally provided with the tooth decorating sheet 6, and certainly, the dentures with the three structures can not be attached.
