Description

Technical Field

[0001] This application relates to the technical field of dentures, and particularly to a detachable and assembled denture. Background Art

[0002] Dentures are what people often call "false teeth". Just as "false legs" and "prostheses" are called "prosthetics", "dentures" means teeth that fulfill an "obligation" for humans. Medically, it is the general term for prostheses made after partial or complete loss of upper and lower teeth; currently, most dentures on the market are composed of a denture base, a denture body, and an elastic gum sleeve.

[0003] During long-term use, the wear degrees of each denture are different, so the final damage times are also different. To avoid replacing the entire denture due to the damage of a single denture body, some detachable methods for the denture body and the base have emerged in the prior art, so that a single damaged denture can be replaced separately without replacing the entire denture body; what most manufacturers ignore is that the denture base will also have the above problems, and some structures of the base may wear out first. If replacement is needed, the whole base needs to be replaced. Therefore, this application aims to provide a denture with a base that can be flexibly maintained. Utility Model Content

[0004] The purpose of this application is to provide a detachable and assembled denture to solve at least one of the above technical problems.

[0005] To solve the above technical problems, this application provides a detachable and assembled denture, including a base and a denture unit detachably disposed on the base;

[0006] The base includes a first unit and a second unit that are detachably connected;

[0007] An arc-shaped extension column is formed on the splicing end surface of the first unit and the second unit, and an arc-shaped groove adapted to accommodate the arc-shaped extension column is formed on the splicing end surface of the second unit and the first unit;

[0008] A clamping block is formed on the splicing end surface of the first unit and the second unit, and a clamping groove adapted to the clamping block is formed on the splicing end surface of the second unit and the first unit, or

[0009] A clamping groove is formed on the splicing end surface of the first unit and the second unit, and a clamping block adapted to the clamping groove is formed on the splicing end surface of the second unit and the first unit;

[0010] In the above implementation process, the present application splits the entire base into two independent units that can be spliced and disassembled. When in use, the arc extension posts on the first unit are inserted into the arc grooves on the second unit to achieve guiding splicing, and the end faces are further tightly connected through the snap blocks and the card slots; with the cooperation of the snap blocks and the card slots, the end faces of the first unit and the second unit are tightly connected, and the arc extension posts extend into the arc grooves. Without a specific force application direction, the arc extension posts and the arc grooves restrict each other to ensure the connection strength; when disassembling, only through a specific force application direction can the two be disassembled, thereby ensuring the stability and connection strength during connection, and also facilitating subsequent disassembly maintenance and replacement.

[0011] Preferably, four arc extension posts are provided and are respectively arranged at the four corners of the end face of the first unit;

[0012] In the above implementation process, four arc extension posts are provided and are distributed at the four corners of the end face of the first unit. The four arc extension posts can enhance the anti-bending strength after connection, and at the same time, being distributed at the four corners can make the force more uniform.

[0013] Preferably, one arc extension post is provided and is located at the center of the end face of the first unit;

[0014] In the above implementation process, this solution is another implementation manner of the arc extension post. The arc extension post is arranged in the center, which can cooperate with the snap blocks and the card slots distributed on the periphery to achieve stable splicing.

[0015] Preferably, four snap blocks are provided and are respectively arranged on the four sides of the end face of the first unit or the second unit;

[0016] In the above implementation process, four snap blocks are provided and are distributed on the four sides of the end face. Whether the arc extension posts are arranged at the four corners or in the center, the snap blocks distributed on the four sides can cooperate to achieve stable clamping, ensure uniform force in all directions, improve the anti-bending and separation ability, and enhance the connection stability.

[0017] Preferably, the snap block is made of anti-slip silica gel;

[0018] In the above implementation process, the snap block is made of anti-slip silica gel, which can increase the relative friction between the snap block and the card slot, thereby enhancing the connection strength.

[0019] Preferably, the denture unit includes a denture main body and a clamping post connected to the denture main body;

[0020] A first through hole that is clamped and matched with the clamping post is formed on the base;

[0021] In the above implementation process, the clamping column is clamped by penetrating into the first through hole, thereby realizing the connection between the denture unit and the base; there is no need to use a threaded rotation method to connect, and the connection process is faster and simpler.

[0022] Preferably, a second through hole communicating with the first through hole is provided on the inner arc surface and / or the outer arc surface of the base;

[0023] The clamping column comprises a column body and a clamping assembly arranged on the column body, and the clamping assembly is suitable for clamping into the second through hole;

[0024] In the above implementation process, the clamping column extends into the first through hole until the clamping assembly is clamped into the second through hole, so as to achieve clamping, and then achieve clamping between the clamping column and the base to achieve fixation; and it can be understood that the second through hole can be set only on one side, that is, it can be an inner arc surface or an outer arc surface, or it can be set on both sides at the same time, that is, to achieve clamping at a single point or clamping at two points; and when disassembling, the clamping assembly is squeezed through the second through hole to make it detach from the second through hole, thereby releasing the clamping state, and then the clamping column can be freely moved to achieve disassembly.

[0025] Preferably, the clamping assembly comprises a positioning block and an elastic member connecting the positioning block and the column body, and the elastic force direction of the elastic member is parallel to the radial direction of the column body;

[0026] In the above implementation process, during assembly, the positioning block is first pressed to compress the elastic part so that it extends into the first through hole. At this time, under the elastic force of the elastic part, the positioning block always abuts against the wall of the first through hole until it reaches the position of the second through hole, and the positioning block then extends into the second through hole to achieve snap-on connection.

[0027] Preferably, convex points are extended and formed on the upper and lower sides of the positioning block, and the convex points are made of elastic material;

[0028] The positioning block is interference-fitted with the second through hole through the elastic material;

[0029] In the above implementation process, the present solution further provides a protrusion made of elastic material on the positioning block so that it can achieve interference fit with the inner wall of the second through hole to improve the stability of the clamping.

[0030] Compared with the prior art, the beneficial effects of the present application are as follows: The entire base of the present application is split into two independent units that can be spliced and disassembled. When in use, the arc-shaped extension post on the first unit is inserted into the arc-shaped groove on the second unit to achieve guiding splicing, and the two are further tightly connected at the end face through the engaging block and the engaging groove; with the cooperation of the engaging block and the engaging groove, the end faces of the first unit and the second unit are tightly connected, and the arc-shaped extension post extends into the arc-shaped groove. Without a specific force application direction, the arc-shaped extension post and the arc-shaped groove restrict each other to ensure the connection strength between the two; when disassembling, the two can be disassembled only through a specific force application direction, thereby ensuring the stability and connection strength during connection, and also facilitating subsequent disassembly maintenance and replacement.

[0042] Embodiment

[0043] During the long-term use of dentures, the wear degrees of individual dentures are different, so the final damage times are also different. To avoid replacing the entire denture due to the damage of a single denture body, some detachable methods between the denture body and the base have emerged in the prior art, so that a single damaged denture can be replaced separately without replacing the entire denture body. However, what most manufacturers ignore is that the denture base will also have the above problems, and some structures of the base may wear out first. If replacement is needed, the whole base needs to be replaced. Therefore, the present application aims to provide a denture in which the base can also be flexibly maintained.

[0044] To solve the above technical problems, the following technical solutions are provided in this embodiment:

[0045] Specifically, please refer to Figures 1-5, this embodiment provides a detachable assembled denture, including a base 10 and a denture unit 30 detachably disposed on the base 10;

[0046] Further, the base 10 includes a first unit 21 and a second unit 22 which are detachably connected;

[0047] Specifically, an arc-shaped extension column 211 is formed by extending on the splicing end face of the first unit 21 and an arc-shaped groove 221 adapted to accommodate the arc-shaped extension column 211 is formed on the splicing end face of the second unit 22 and the first unit 21;

[0048] Further, a latch 23 is formed on the splicing end face of the first unit 21 and the second unit 22, and a card slot 24 adapted to the latch 23 is formed on the splicing end face of the second unit 22 and the first unit 21, or,

[0049] A card slot 24 is formed on the splicing end face of the first unit 21 and the second unit 22, and a latch 23 adapted to the card slot 24 is formed on the splicing end face of the second unit 22 and the first unit 21;

[0050] In the above solution, the present application splits the entire base 10 into two independent units that can be spliced and disassembled. When in use, the arc-shaped extension column 211 on the first unit 21 is inserted into the arc-shaped groove 221 on the second unit 22 to achieve guiding splicing, and the two are further tightly connected at the end face through the latch 23 and the card slot 24; with the cooperation of the latch 23 and the card slot 24, the end faces of the first unit 21 and the second unit 22 are tightly connected, and the arc-shaped extension column 211 extends into the arc-shaped groove 221. Without a specific force application direction, the arc-shaped extension column 211 and the arc-shaped groove 221 restrict each other to ensure the connection strength between the two; and when disassembling, the two can be disassembled only through a specific force application direction, thereby ensuring the stability and connection strength during connection, and at the same time facilitating subsequent disassembly maintenance and replacement.

[0051] In one of the embodiments, reference may be made to Figure 4 , four arc-shaped extension columns 211 are provided and are respectively disposed at the four corners of the end face of the first unit 21;

[0052] In the above solution, four arc-shaped extension columns 211 are provided and are distributed at the four corners of the end face of the first unit 21. The four arc-shaped extension columns 211 can enhance the anti-bending strength after connection, and at the same time, being distributed at the four corners can make the force more uniform.

[0053] In one of the embodiments, please refer to Figure 5 , one arc-shaped extension column 211 is provided and is located at the center of the end face of the first unit 21;

[0054] In the above solution, this solution is another implementation of the arc-shaped extension column 211. The arc-shaped extension column 211 is arranged in the center and can be stably spliced in cooperation with the clamping blocks 23 and clamping grooves 24 distributed on the periphery.

[0055] In one implementation, there are four clamping blocks 23, which are respectively arranged on the four sides of the end face of the first unit 21 or the second unit 22;

[0056] In the above solution, there are four clamping blocks 23, which are distributed on the four sides of the end face. Whether the arc-shaped extension column 211 is arranged at the four corners or in the center, the clamping blocks 23 distributed on the four sides can cooperate to achieve stable clamping, ensure uniform force in all directions, improve the ability to resist bending and separation, and enhance the connection stability.

[0057] Furthermore, the clamping block 23 is made of anti-slip silica gel;

[0058] In the above solution, the clamping block 23 is made of anti-slip silica gel, which can increase the relative friction between the clamping block 23 and the clamping groove 24, and thus improve the connection strength.

[0059] Furthermore, in one implementation, the end faces of the first unit 21 and the second unit 22 can be further adhered with hot melt adhesive to enhance the connection strength; and during disassembly, the hot melt adhesive can be melted by certain heating to achieve disassembly; of course, it can be understood that further using hot melt adhesive is only to assist in improving the connection strength.

[0060] Specifically, please refer to Figure 3 , the denture unit 30 includes a denture main body 31 and a clamping column 32 connected to the denture main body 31;

[0061] Furthermore, a first through hole 11 that is clamped and matched with the clamping column 32 is formed on the base 10;

[0062] In the above solution, the clamping column 32 is clamped by penetrating into the first through hole 11, thereby realizing the connection between the denture unit 30 and the base 10; there is no need to use the way of threaded rotation for connection, and the connection process is more rapid and convenient.

[0063] Specifically, a second through hole 12 communicated with the first through hole 11 is provided on the inner arc surface and / or the outer arc surface of the base 10;

[0064] Furthermore, the clamping column 32 includes a column body main body 321 and a clamping component 322 arranged on the column body main body 321, and the clamping component 322 is adapted to be clamped into the second through hole 12;

[0065] In the above scheme, the clamping column 32 extends into the first through hole 11 until the clamping component 322 is clamped into the second through hole 12, so as to achieve clamping, and then achieve clamping between the clamping column 32 and the base 10 to achieve fixation; and it can be understood that the second through hole 12 can be set only on one side, that is, it can be an inner arc surface or an outer arc surface, or it can be set on both sides at the same time, that is, to achieve clamping at a single point or clamping at two points; and when disassembling, the clamping component 322 is squeezed through the second through hole 12 to make it detach from the second through hole 12, and the clamping state is released, so that the clamping column 32 can be freely moved and disassembled.

[0066] Furthermore, the clamping assembly 322 includes a positioning block 3222 and an elastic member 3221 connecting the positioning block 3222 and the column body 321, and the elastic force direction of the elastic member 3221 is parallel to the radial direction of the column body 321;

[0067] In the above scheme, during assembly, the positioning block 3222 is first pressed to compress the elastic member 3221 so that it extends into the first through hole 11. At this time, under the elastic force of the elastic member 3221, the positioning block 3222 always abuts against the wall of the first through hole 11 until it reaches the position of the second through hole 12. The positioning block 3222 then extends into the second through hole 12 to achieve snap-on connection.

[0068] Furthermore, the elastic member 3221 may be a compression spring.

[0069] Specifically, protrusions 40 are extended and formed on both sides of the upper and lower sides of the positioning block 3222, and the protrusions 40 are made of elastic material;

[0070] Further, the positioning block 3222 is interference-fitted with the second through hole 12 through the elastic material;

[0071] In the above solution, the present solution further provides a protrusion 40 made of elastic material on the positioning block 3222 so that it can achieve interference fit with the inner wall of the second through hole 12 to improve the stability of the clamping.

[0072] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
