Technical Field

The invention relates to the technical field of false teeth, in particular to a self-adaptive buffering false tooth which can effectively relieve discomfort brought to people by a new artificial tooth.

Background

The denture is what is commonly called a "denture". Just like "leg prosthesis" and "prosthetic limb" are referred to as "prosthetic limb", a "denture" means that the human being is "obligated" to the utmost. The medical science is a general term for restorations made after partial or all teeth of the upper and lower jaws are lost.

The false tooth replaces the original natural tooth of people when in use, and is frequently used as a part of the oral cavity of a human body, so that the adaptation of the false tooth is very important for people. Even if a plurality of factors are considered in the manufacturing process of the false tooth, a long break-in period is inevitable during use due to the existence of a plurality of uncontrollable factors such as oral cavity environment, eating strength and the like of each person; in the grinding period, people need to overcome the discomfort and pressure brought by the false teeth to the oral cavity, the false teeth which are successfully ground can be normally used, but some people are difficult to grind, and the false teeth need to be remade according to personal feelings. Even among people who have a successful running-in, there is a portion of suffering from considerable pain and discomfort.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide the self-adaptive buffering denture which can effectively relieve the pain and the discomfort brought to people by the new denture and can quickly adapt to the use of the denture.

In order to achieve the purpose, the invention adopts the following technical scheme:

a self-adaptive buffering false tooth comprises a base which is attached to a gum and a tooth body which is fixedly connected with the base; the tooth body comprises a cup-shaped fixed body and a self-aptamer which is positioned in the fixed body and is inserted from outside, and the height of the self-aptamer is not lower than that of the fixed body; the fixing body is bent inwards at the cup edge and then extends outwards to form an elastic positioning closing-in, an inward-protruding buffering elastic sheet is arranged on the inner side of the cup wall at the lower part of the fixing body, the buffering elastic sheet has a certain radian, a filling gasket is arranged in the radian range of the buffering elastic sheet, and an outward-protruding arc groove is formed in the inner side of the cup wall corresponding to the buffering elastic sheet of the fixing body; the side wall of the insertion end of the self-adaptive body is provided with a wave-shaped buffer area, and the side wall of the end part at the other end is inwards deviated to form a positioning boss matched with the positioning closing-in shape; after the self-adaptive body is inserted into the fixing body, the positioning closing-in is matched with the positioning boss, and the insertion end of the self-adaptive body is positioned in the range of the buffering elastic sheet.

Preferably: the buffering elastic sheet is a wavy metal sheet, and a polypropylene layer and a rubber and plastic anti-slip fiber layer are fixedly attached to one side in the cup in sequence.

Preferably: the buffering elastic pieces are evenly divided into three groups along the circumferential direction of the cup wall of the fixing body and are located at the same height.

Preferably: the inner side of the bottom of the fixed body is embedded with a micro magnet, and the bottom surface of the self-adaptive inserting end is embedded with a ferromagnetic adsorption block.

Preferably: the bottom of the fixed body is provided with a T-shaped groove, and the miniature magnet is embedded in the bottom surface of the groove; one end of the adsorption block is elastically connected with the self-adaptive body, and two sides of the other end of the adsorption block are elastically connected with the telescopic arms; when the insertion end of the aptamer is close to the wall bottom of the fixing body, the adsorption block is magnetically adsorbed, overcomes the elasticity, extends into the groove, and extends out under the elastic action of the telescopic arm after reaching the bottom end of the groove to fill the groove.

Preferably: and an anti-slip groove is formed in the inner wall of the positioning closing-in, and an annular gasket is arranged in the anti-slip groove.

Preferably: the filling gasket is a rubber gasket.

Compared with the prior art, the method has the advantages of good self-adaptive buffering effect; when in use, the fixing body is fixedly connected with the base, and the self-adaptive body is positioned in the fixing body and plays a main role in tooth chewing; when the self-adaptive body is stressed (towards the upper jaw and the lower jaw), the wavy buffer area and the buffering elastic sheet are mutually rubbed in and extruded to play a role in buffering the occlusal force of the upper jaw and the lower jaw, and the self-adaptive body gradually moves towards the cup bottom of the fixed body after long-term use (false tooth rubbing in period), so that the oral environment of people gradually adapts to new false teeth.

There are several aspects to the buffering action: 1. the outer wall of the wave-shaped self-adaptive buffer area plays a role in shape buffering through the extrusion of the buffering elastic sheet; 2. the metal elasticity of the buffering elastic sheet, the polypropylene layer outside the buffering elastic sheet and the rubber-plastic anti-skid fiber layer play a role in buffering materials for elastic extrusion; 3. the fixed body has set up the arc groove in the cup wall inboard that the buffering shell fragment corresponds, is equipped with the packing gasket in the radian within range of buffering shell fragment, at the in-process that removes gradually from the aptamer, fills up the arc groove gradually with the packing gasket, and the arc groove that fills up gradually makes buffering shell fragment shape change, weakens gradually to the elastic effect of inboard, plays and gradually slows down buffering effect, self-adaptation buffering effect promptly. Three groups of buffering elastic sheets which are uniformly distributed along the circumferential direction of the cup wall of the fixing body can greatly improve the three buffering effects, and the whole denture is uniformly and stably stressed in the movement of the self-adaptive body.

In addition, the miniature magnet and the adsorption block are arranged at the bottom of the fixing body and the bottom of the self-adaptive body, so that the self-adaptive body can be connected more stably and reliably after being used for a long time and reaching the bottom of the fixing body.

Detailed Description

The structure and principles of the adaptive cushioning denture described in this invention will now be described in conjunction with specific embodiments, so as to enable one of ordinary skill in the art to fully understand and implement the same.

Example 1

As shown in fig. 1-3: a self-adaptive buffering false tooth comprises a base which is attached to a gum and a tooth body which is fixedly connected with the base; the tooth body comprises a cup-shaped fixed body 1 and an adaptive body 2 which is positioned in the fixed body 1 and is inserted from the outside, and the height of the adaptive body 2 is not lower than that of the fixed body 1; the fixing body 1 is bent inwards at the cup edge and then extends outwards to form an elastic positioning closing-in 11, an inward-protruding buffering elastic sheet 12 is arranged on the inner side of the cup wall at the lower part of the fixing body 1, the buffering elastic sheet 12 is in a certain radian, a filling gasket 13 (the filling gasket 13 is a rubber gasket) is arranged in the radian range of the buffering elastic sheet 12, and an outward-protruding arc groove 14 is arranged on the inner side of the cup wall corresponding to the buffering elastic sheet 12 of the fixing body 1; a wave-shaped buffer area 22 is arranged on the side wall of the insertion end of the self-adaptive body 2, and the side wall of the end part at the other end is inwards deviated to form a positioning boss 21 matched with the positioning closing-in 11 in shape; after the self-adaptive body 2 is inserted into the fixing body 1, the positioning closing-in 11 is matched with the positioning boss 21, and the insertion end of the self-adaptive body 2 is positioned in the range of the buffering elastic sheet 12.

During the use process, the self-adaptive body 2 is inserted into the fixing body 1, the end part of the buffer area 22 is positioned in the range of the buffer shrapnel 12, preferably, the positioning boss 21 just enters the positioning closing-in 11 just before reaching the buffering elastic sheet 12, so as to realize the initial positioning during use (in order to achieve better effect, the inner wall of the positioning closing-in 11 is provided with the anti-slip groove 17, the anti-slip groove 17 is internally provided with the annular gasket 18), along with the use of the denture, the biting force of the oral cavity of the user enables the self-adaptive body 2 to gradually move towards the bottom of the fixed body 1, because the buffer shrapnel 12 and the buffer area 22 can effectively reduce the pressure of the occlusal force on the false tooth, thereby reducing the stress of the base, thereby reducing the burden of the gum, the buffering elastic sheet 12 is gradually deformed along with the gradual downward movement of the self-adaptive body 2, the arc groove 14 is gradually filled up, the buffer force is gradually weakened, so that the oral cavity of people gradually adapts to the occlusal force, and the gum gradually adapts to the false teeth. When people feel that the gum burden is too heavy, the biting force naturally becomes light, the buffering deformation naturally becomes slow, and a good self-adaptive effect is achieved. When people gradually adapt to the false teeth, the biting force is normal, and the self-adaptive body 2 moves downwards until the bottom of the fixed body 1.

In this embodiment, the buffering engagement pressure mainly comes from the following aspects: first, the glass-shaped buffer area 22 acts as a buffer spring 12; secondly, the elastic extrusion effect of the elastic sheet 12 is buffered; and thirdly, filling the self-adaptive buffering effect after the gasket 13 and the buffering elastic sheet 12 are gradually deformed.

As can be seen from the above, the buffering elastic sheet 12 plays an important role in buffering pressure, and in order to achieve a more ideal buffering effect, the following improvements are made to the buffering elastic sheet 12. As shown in figure 4, the buffering elastic sheet 12 is a wavy metal sheet, and a polypropylene layer 12-1 and a rubber and plastic anti-slip fiber layer 12-2 are fixedly attached to one side of the cup in sequence. The metal sheet can improve the strength of the buffering elastic sheet 12, and the polypropylene layer 12-1 and the rubber-plastic anti-skid fiber layer 12-2 play roles in damping anti-skid and weakening the quick deformation of the metal sheet, and have good transition effects.

As shown in fig. 5; in a preferred embodiment: the buffering elastic pieces 12 are evenly divided into three groups along the circumferential direction of the cup wall of the fixing body 1 and are located at the same height. Through the arrangement, the force of the self-adaptive body 2 on the fixing body 1 is stable in the moving process, unbalanced pressure brought to the base support is avoided, and the uniform distribution of the self-adaptive body is optimal when the self-adaptive body forms a regular triangle with the same plane.

Example 2

As shown in fig. 6, the present embodiment is modified based on embodiment 1 as follows: wherein the inner side of the cup bottom of the fixed body 1 is embedded with a micro magnet 15, and the bottom surface of the insertion end of the aptamer 2 is embedded with a ferromagnetic adsorption block 23.

When the self-adaptive body 2 reaches the bottom of the fixed body 1, the connection between the self-adaptive body 2 and the fixed body 1 is more stable through the magnetic adsorption effect of the miniature magnet 15 and the adsorption block 23, and a double-insurance effect is achieved. (since the aptamer 2 and the fixed body 1 can be stabilized by lateral pressure and the ring washer 18, and is more stable under the biting force of people, the whole structure stability can be greatly improved by only small magnetism)

Example 3

As shown in fig. 7 and 8, in this embodiment, a magnetic adsorption structure is further optimized based on embodiment 2, specifically as follows: the bottom of the fixed body 1 is provided with a T-shaped groove 16, and the micro magnet 15 is embedded in the bottom surface of the groove 16; one end of the adsorption block 23 is elastically connected with the aptamer 2, and the two sides of the other end are elastically connected with a telescopic arm 23-1; when the insertion end of the aptamer 2 approaches the wall bottom of the fixed body 1, the adsorption block 23 is magnetically adsorbed, extends into the groove 16 by overcoming the elasticity, and extends out of the telescopic arm 23-1 under the action of the elasticity after reaching the bottom end of the groove 16 to fill the groove 16. Through the improvement, the self-aptamer 2 and the immobilized body 1 are added with T-shaped structural stability on the basis of magnetic adsorption. Can effectively keep stable even when the oral cavity is impacted by external force, and prevent accidents.
