Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral appliances, in particular to an ultra-thin tooth veneer with strong effectiveness. Background Art
[0002] Dental veneers are a type of dental material used primarily to improve the appearance of teeth. They are usually applied to cover the front surface of teeth to improve their color, shape or alignment. Most of these products are designed for the front area and are mainly focused on enhancing aesthetics. They are suitable for treating minor imperfections or uneven color of teeth.
[0003] However, existing dental veneer designs mainly focus on improving visual effects and are not optimized for tooth areas with greater chewing pressure. In daily diet, the back molars are responsible for most of the chewing work, while the front teeth are mainly used for biting. If dental veneers are applied to these more functional areas, they are often unable to withstand frequent and strong chewing or biting actions due to design limitations (such as single-layer structure and the use of a single adhesive). In this high-pressure environment, traditional dental veneers often fall off, which not only affects their practicality but also reduces their durability.
[0004] Therefore, there is an urgent need to develop a new type of dental veneer, especially a dental veneer designed for posterior molars. Utility Model Content
[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide an ultra-thin dental veneer with strong effectiveness.
[0006] The technical solution of the utility model is as follows: an ultra-thin dental veneer with strong effectiveness, comprising a veneer body, the veneer body is arranged as a U-shaped structure, reinforcement grooves are symmetrically and equidistantly arranged inside the veneer body, the reinforcement grooves are arranged as a convex structure, adjustment grooves are symmetrically arranged inside the veneer body and located outside the reinforcement grooves, the adjustment grooves are arranged as an inclined structure, an adjustment strut is movably connected between two corresponding adjustment grooves, two arc surfaces are arranged at the bottom corners of the veneer body, and a plane is arranged at the bottom of the veneer body and located between the two arc surfaces.
[0007] Through the above-mentioned technical means, when the U-shaped dental veneer body is installed to the posterior molar position, the veneer body will deform accordingly according to the different thicknesses of the posterior molars. The veneer body itself has good elasticity and can tightly clamp the patient's posterior molars, and the adjustment strut is used to adjust the clamping force to ensure that it does not cause discomfort to the patient and optimize the user experience. During the installation process, the staff will apply a larger amount of UV glue because the posterior molars have a stronger bite force. For this reason, a reinforcement groove is specially designed. The purpose of the groove is to enhance the contact strength between the colloid and the gums, thereby further enhancing the bonding force between the dental veneer body and the gums. This design takes into account the special chewing force of the posterior molars to ensure the stability and durability of the dental veneer in daily use.
[0008] As a preferred embodiment, the veneer body is composed of an elastic layer, a reinforcement layer, a connecting layer, a contact layer and a chewing layer. The reinforcement layer is arranged on the outside of the connecting layer, and the elastic layer is arranged on the outside of the reinforcement layer. The elastic layer, the reinforcement layer and the connecting layer are arranged as a group, and there are two groups in total, and the chewing layer is arranged at the bottom of the two groups, and the contact layer is arranged inside the chewing layer and between the two connecting layers.
[0009] As a preferred embodiment, the elastic layer is made of polyurethane and its density is set to 1200 kg / m 3 , the tensile strength is set between 25-50MPa, the elongation is set between 300% and 600%, and the hardness is set between 5-9MPa.
[0010] Through the above-mentioned technical means, the high elongation and moderate hardness provided by the polyurethane material enable this layer to provide good flexibility and adaptability without sacrificing the overall stability of the dental veneer, so that the dental veneer can adapt to the slight differences in the teeth of different patients while maintaining a comfortable fit.
[0011] As a preferred embodiment, the reinforcing layer is set to be made of carbon fiber material, and its density is set at 1750-2000kg / m 3 The tensile strength is set between 3500-5000MPa, and the elastic modulus is set between 230-430GPa.
[0012] Through the above-mentioned technical means, carbon fiber ensures the structural strength and durability of the dental veneer with its high density, extremely high tensile strength and elastic modulus. The setting of the reinforcement layer helps the dental veneer to resist the pressure and impact in daily use, greatly improving the life of the product.
[0013] As a preferred embodiment, the connection layer is made of polyvinyl alcohol, and the connection layer is used to connect the contact layer and the reinforcement layer.
[0014] Through the above technical means, the connecting layer can effectively bond the contact layer and the reinforcement layer together to provide stable structural support. The stable chemical properties of polyvinyl alcohol ensure long-term bonding reliability and prevent the degradation of bonding performance due to environmental changes or humidity.
[0015] As a preferred embodiment, the contact layer is made of medical silicone material, which is in direct contact with the teeth and gums.
[0016] Through the above-mentioned technical means, medical silicone is in direct contact with teeth and gums, providing excellent biocompatibility and softness, which can reduce pressure on teeth, reduce potential irritation or injury risks, and increase wearing comfort, making it particularly suitable for sensitive gum environments.
[0017] As a preferred embodiment, the chewing layer is made of zirconium oxide ceramic material, and its density is set to 6050 kg / m 3 , the bending strength is set between 900-1200MPa, the fracture toughness is set between 5-10MPa·m^1 / 2, and the hardness is set to 12GPa.
[0018] Through the above-mentioned technical means, zirconia ceramics have extremely high density, bending strength and hardness, making this layer the most suitable part of the dental veneer to withstand chewing pressure. Its high fracture toughness further ensures that the dental veneer will not be damaged due to force during chewing, greatly improving the safety and durability of use.
[0019] Compared with the prior art, the advantages and positive effects of the utility model are:
[0020] 1. The utility model arranges reinforcement grooves and adjustment grooves at equal intervals inside, and cooperates with the adjustment support rod, so that the veneer can not only fit the back molars of different thicknesses, but also withstand the pressure of daily chewing movements. This structural design makes the dental veneer not only provide aesthetic effects, but also increase practicality, allowing users to chew normally while wearing it, effectively improving the user experience and quality of life;
[0021] 2. The utility model adopts materials such as polyurethane, carbon fiber, polyvinyl alcohol, medical silicone and zirconium oxide ceramics, and combines the advantages of these high-performance materials to ensure the stability and durability of the dental veneer when it is subjected to chewing force, while maintaining good contact with the gums, reducing damage to the teeth themselves, and providing long-term comfort. The use of this material combination greatly improves the overall performance of the dental veneer, taking into account its functionality and aesthetics in daily life.

[0031] In summary: When the U-shaped dental veneer body 1 is installed to the posterior molar position, the veneer body 1 will deform accordingly according to the different thicknesses of the posterior molars. The veneer body 1 itself has good elasticity and can tightly clamp the patient's posterior molars, and the adjustment support rod 4 is used to adjust the clamping force to ensure that it does not cause discomfort to the patient and optimize the user experience.

[0034] In summary: The high elongation and moderate hardness provided by the polyurethane material enable this layer to provide good flexibility and adaptability without sacrificing the overall stability of the dental veneer, so that the dental veneer can adapt to the slight differences in the teeth of different patients while maintaining a comfortable fit.
[0035] like Figure 4 As shown, the reinforcing layer 12 is set to be made of carbon fiber material, the density of which is set between 1750-2000kg / m3, the tensile strength is set between 3500-5000MPa, and the elastic modulus is set between 230-430GPa;
[0036] In summary: carbon fiber ensures the structural strength and durability of the dental veneer with its high density, extremely high tensile strength and elastic modulus. The provision of the reinforcement layer 12 helps the dental veneer to resist pressure and impact in daily use, greatly improving the life of the product.

[0038] In summary: the connecting layer 13 can effectively bond the contact layer 14 and the reinforcing layer 12 together, providing stable structural support. The stable chemical properties of polyvinyl alcohol ensure long-term bonding reliability and prevent the degradation of bonding performance due to environmental changes or humidity.
[0039] like Figure 4 As shown, the contact layer 14 is set to be a medical silicone material, which is in direct contact with the teeth and gums;
[0040] In summary: Medical silicone is in direct contact with teeth and gums, providing excellent biocompatibility and softness, which can reduce pressure on teeth and reduce potential risks of irritation or injury, while increasing wearing comfort, and is particularly suitable for sensitive gum environments.
[0041] like Figure 4 As shown, the chewing layer 15 is made of zirconium oxide ceramic material, and its density is set to 6050 kg / m 3 , the bending strength is set between 900-1200MPa, the fracture toughness is set between 5-10MPa·m^1 / 2, and the hardness is set to 12GPa;
[0042] In summary: Zirconia ceramics have extremely high density, bending strength and hardness, making this layer the most suitable part of the dental veneer to withstand chewing pressure. Its high fracture toughness further ensures that the dental veneer will not be damaged due to force during chewing, greatly improving its safety and durability.
[0043] Working principle:
[0044] The ultra-thin dental veneer provided by the utility model includes a veneer body 1 of a U-shaped structure, which is designed to adapt to the shape of the posterior molars. The interior of the veneer body 1 is symmetrically and equidistantly provided with reinforcement grooves 2, which adopt a convex structure to enhance the stability and durability of the structure. At the same time, inside the veneer body 1, the adjustment groove 3 located outside the reinforcement groove 2 adopts a slope structure, which cooperates with the movable adjustment struts 4 on both sides, allowing the adjustment struts to move freely to adapt to the different thicknesses of teeth. This design allows the veneer body 1 to undergo necessary deformation according to the specific shape of the posterior molars during installation, while ensuring that it will not cause discomfort to the patient, thereby optimizing the user experience.
[0045] The elastic layer 11 is made of polyurethane, which not only has excellent elongation and appropriate hardness, so that the veneer body can maintain good elasticity and recovery when deformed, but also can fit closely to the patient's teeth, providing a comfortable feeling of use. The carbon fiber material of the reinforcing layer 12 provides extremely high tensile strength and elastic modulus, enhances the structural strength and impact resistance of the veneer, and ensures stability for long-term use. The contact layer 14 uses medical silicone, which is in direct contact with the teeth and gums, providing compatibility and softness to reduce irritation. Finally, the chewing layer 15 is made of zirconium oxide ceramics, which is suitable for bearing chewing pressure. Its high density and bending strength ensure safety and durability during use. Through such selection and optimization, the high performance of the dental veneer in terms of functionality, comfort and durability is ensured.
