Description

High-strength low-cost false tooth with novel structure

Technical Field

The utility model relates to an artificial tooth technical field especially relates to a novel structure artificial tooth that structural strength is high, with low costs, light in weight.

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.

With the improvement of the quality of life of people, the requirement of people on denture materials is gradually improved, the good denture materials (noble metals) are expensive, the demand of the denture is gradually expanded, and most people cannot enjoy high-quality dentures made of the expensive materials.

In addition, most of the dentures on the market are full-solid dentures (i.e., complete filling of the denture material from inside to outside), which have the following defects: 1. the consumption of denture materials is large, the cost is high for the denture made of expensive materials, and the resource waste is caused to a certain extent for the denture surfaces actually used; 2. dentures are heavy, especially for multiple dentures or full dentures, increasing the burden of chewing in the mouth.

Disclosure of Invention

In order to overcome the above defects of the prior art, the utility model aims to provide a novel structure false tooth which has low cost, large structural strength and light weight and is helpful for chewing in the oral cavity.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a high-strength low-cost false tooth with a novel structure comprises a base and a tooth body, wherein the tooth body consists of a hollow cavity, a metal structure layer, a bamboo buffer layer and a chewing surface layer from inside to outside; the metal structure layer is a frame structure formed by metal; the bamboo buffer layer is formed by joggling the upper half layer and the lower half layer into a whole; the chewing surface layer is covered outside the bamboo buffer layer in a 3D printing mode.

Preferably: the top surface and the bottom surface of the metal structure layer are oval and are connected into a whole up and down through a plurality of pillars.

Preferably: the number of the pillars of the metal structure layer is 4, and the pillars are uniformly distributed on the side wall of the metal structure layer.

Preferably: the thickness of the bamboo buffer layer is 1.8 mm-3.5 mm.

Preferably: the thickness of the top of the chewing surface layer is 0.8 mm-1.6 mm, and the thickness of the side wall is 0.5 mm-1.2 mm.

Preferably: the material of the chewing surface layer is porcelain or noble metal.

Compared with the prior art, the utility model, have following advantage:

1. the cost of the false tooth is greatly reduced through the structural design. Designing the denture structure into a hollow cavity, a metal structure layer, a bamboo buffer layer and a chewing surface layer; wherein, only the chewing surface layer is used for the oral cavity, the cost is greatly reduced for expensive false tooth materials, and the bamboo material of the bamboo buffer layer has low cost; the simple structure of the metal structure layer (frame structure) does not have a high cost even if a high-performance alloy material is used.

2. The cost is reduced and the structural strength is improved. The metal structure layer is added in the denture, so that the structural strength of the denture is improved (the frame system of the metal structure layer shares the occlusal force of the oral cavity through the surface layer, and compared with the traditional denture material, the denture material can completely share the occlusal force, so that the denture has improved strength and prolonged service life).

3. Has the effects of buffering and assisting chewing. The metal structure layer and the bamboo buffer layer form an internal hollow structure, the outside of the metal structure layer and the bamboo buffer layer is in a micro-elastic 'air bag' shape, the micro-elasticity of the bamboo can reduce the oppression effect of the oral occlusal force on the false tooth, and the resilience is also beneficial to oral chewing.

Detailed Description

The construction and principles of the invention are now fully described in connection with the specific embodiments thereof so as to enable one of ordinary skill in the art to fully understand and implement the invention.

As shown in fig. 1 and 2, a high-strength low-cost denture with a novel structure comprises a base and a tooth body, wherein the base is fixed on the gingival base of the oral cavity, and the tooth body is fixedly connected with the base; wherein the tooth body consists of a hollow cavity 1, a metal structure layer 2, a bamboo buffer layer 3 and a chewing surface layer 4 from inside to outside; the metal structure layer 2 is a frame structure formed by metal, the top surface and the bottom surface of the metal structure layer are oval, and the metal structure layer and the bottom surface are connected into a whole up and down through four pillars 2.1; the bamboo buffer layer 3 is joggled and connected into a whole by an upper half layer 3.1 and a lower half layer 3.2; the chewing surface layer 4 is covered outside the bamboo buffer layer 3 in a 3D printing mode.

Wherein metal structure layer 2 is located the internal side of tooth, and it can be integrative with bamboo buffer layer 3 fixed connection, also can only be limited through the structure position. The fixed connection is integrative, can inlay bamboo buffer layer 3 internal surface through upper and lower surface layer, also can connect (screw) or bond through mechanical system.

In the use process of the denture, the oral action can be completed only through the chewing surface layer 4, and the appearance is only shown on the chewing surface layer 4, so that the denture can be used only as the using amount of the chewing surface layer 4 for expensive materials, and the material cost of the denture is greatly reduced.

The frame structure formed by the metal structure layer 2 is matched with the bamboo buffer layer 3 and the hollow cavity 1 to form a buffer air bag on the whole, so that the chewing pressure of the oral cavity can be effectively reduced, and the adaptability of the false tooth can be improved particularly when the oral cavity eats food with high hardness; the hollow chamber 1 not only greatly saves various material costs, but also greatly reduces the weight of the false tooth and improves the comfort when the false tooth is worn.

Bamboo buffer layer 3 is integrative through first half layer 3.1 and lower half layer 3.2 joggle, and traditional joggle connection has reduced the use of part, and easy to assemble, and firm reliable, prints through the 3D in later stage and covers chewing surface layer 4 and can make it form unified whole, and the occlusal force in oral cavity is vertical, therefore the connection of structure is more reliable from top to bottom, long service life.

Preferably: bamboo buffer layer 3 thickness is 1.8mm ~ 3.5 mm.

Preferably: the thickness of the top of the chewing surface layer 4 is 0.8 mm-1.6 mm, and the thickness of the side wall is 0.5 mm-1.2 mm.

Preferably: the chewing surface layer 4 is made of porcelain or precious metal.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any manner. The technical solution of the present invention can be changed and modified in many ways by the method disclosed above, or modified to equivalent embodiments with equivalent changes, without departing from the technical principle and scope of the present invention. Therefore, do not break away from the utility model discloses a principle or scheme, the foundation the utility model discloses a technical essence is right the utility model discloses any combination, modification or replacement that technical characteristic made all shall belong to the technical scheme's of the utility model protection scope.
