[0002] Porcelain fused to metal is an artificial crown formed by fusing low-melting porcelain onto a metal base crown or an all-ceramic base crown. It is used to repair tooth defects, discoloration, deformities, and other problems, and restore the shape, function, and beauty of teeth. Porcelain fused to metal is suitable for patients with discolored teeth, tooth defects, tooth deformities, uneven dentition, missing teeth, etc. who need tooth restoration and aesthetic improvement.

[0003] However, when repairing teeth, the enamel of the abutment teeth needs to be removed to place porcelain teeth, which is very harmful to the abutment teeth, especially for young patients. Repairing one tooth may require grinding away the enamel of two healthy abutment teeth, and enamel is the hardest tooth tissue in the human body. Tooth preparation relies on manual operation, and some doctors find it difficult to strictly follow the standard operation, which can easily lead to secondary caries. In addition, although the adhesives of porcelain teeth, such as polycarboxylate cement or glass ionomer, are less irritating, they have poor bonding strength, and due to the different expansion coefficients of metal and dentin, microleakage is difficult to avoid. After the enamel is worn away, the teeth are prone to caries, and the existing dentin adhesives cannot replace enamel.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] like Figure 1-Figure 4 As shown, the present application provides a combined porcelain tooth, including a porcelain tooth component 10, which is used to repair tooth defects or aesthetic problems. The porcelain tooth component 10 includes a bracket 11, which can be a lingual part. The bracket 11 is similar to the shape of a tooth crown, and has a certain curvature and curved surface structure, so as to occlude normally with the opposing teeth and have good adjacency with the adjacent teeth. The bracket 11 can be a high-strength steel precision casting method. The high-strength steel has excellent strength and toughness, and can withstand large chewing forces without being easily deformed or broken. In the lingual position, it can firmly support the restoration, whether it is daily chewing movements or occasional large-force bites, it can effectively cope with it, ensuring the long-term stability of the repair effect.

[0028] At the same time, a transverse plate 12 is fixedly installed between the brackets 11, and the transverse plate 12 can be used to connect the arc-shaped curved surface structures on both sides, so that the transverse plate 12 can combine the arc-shaped curved surface structures on both sides. At the same time, the arc-shaped curved surface structure of the bracket 11 is designed to conform to the arrangement of teeth and the shape of gums in the oral cavity, and can better adapt to the oral environment, reduce stimulation to the gums and oral mucosa, and also help the porcelain teeth to be positioned and retained in the oral cavity, making it more coordinated with the surrounding tissues.

[0029] A bridge 14 is arranged on the horizontal plate 12, and the bridge 14 can be on the buccal side, and the bridge 14 can be made of metal porcelain. The metal porcelain material combines the high strength of metal with the aesthetics of porcelain. On the buccal side, the porcelain part can be professionally colored and textured to highly simulate the appearance of natural teeth, with natural color and realistic texture, which can effectively improve the overall aesthetics of the patient's teeth and meet social and aesthetic needs; at the same time, the internal metal base provides sufficient support for the restoration, so that it can withstand a large bite force during chewing, is not easy to break or deform, ensures the durability of the restoration, and maintains a long-term stable chewing function.

[0030] At the same time, a slot 15 is opened on the bridge body 14 near the cross plate 12, and the interior of the slot 15 is adapted to the cross plate 12, so that the bridge body 14 can be installed on the cross plate 12 through the slot 15. At the same time, a porcelain surface 16 is bonded to the bridge body 14, and the porcelain surface 16 is above the bridge body 14. The bridge body 14 and the porcelain surface 16 can be used with an adhesive, so that the porcelain surface 16 can be fixed on the bridge body 14 and can be used.

[0031] The adhesive can be made of epoxy resin, which has high-strength bonding properties and good bonding strength to a variety of materials such as metals, ceramics, glass, etc.; it has a small shrinkage rate after curing and good dimensional stability; it has good chemical corrosion resistance, water resistance and heat resistance. At the same time, in oral restorations, it can be used to bond crowns, inlays and other restorations.

[0032] At the same time, the adhesive can also be made of acrylic resin. Compared with epoxy resin, the acrylic resin has a fast light curing speed and can reach a higher strength in a short time; it has good transparency and aesthetics; it has good operating performance, fluidity and plasticity.

[0033] The adhesive can also be made of polyurethane resin. Compared with acrylic resin, the polyurethane resin has excellent flexibility and impact resistance, can adapt to the difference in thermal expansion coefficients between different materials, and has many other characteristics such as good wear resistance and low temperature resistance.

[0034] The cross plate 12, the bridge body 14 and the porcelain surface 16 are all provided with threaded holes 13. When the bridge body 14 is installed on the bracket 11 through the cross plate 12, the three groups of threaded holes 13 can be aligned. The three groups of threaded holes 13 are all threadedly connected with screws 17, so that the screws 17 can fix the cross plate 12, the bridge body 14 and the porcelain surface 16.

[0035] When the mounting retention force of the bracket 11, the bridge body 14 and the porcelain surface 16 is insufficient, the screws 17 can provide additional mechanical retention force to ensure that the porcelain tooth assembly 10 as a whole can function stably and long-term in the oral cavity and reduce the risk of loosening or falling off of the restoration.

[0036] At the same time, a sleeve 19 is sleeved on the screw 17. The sleeve 19 can be made of thin-walled metal, and the inner diameter of the sleeve 19 is slightly larger than the diameter of the screw 17 so that the screw 17 can pass through smoothly. A plurality of longitudinal open grooves are opened on the tube wall of the sleeve 19. These open grooves enable the sleeve 19 to produce radial expansion and deformation when subjected to radial force, thereby increasing the friction between the sleeve 19 and the screw 17, thereby further improving the fastening performance and anchoring reliability of the porcelain tooth component 10, ensuring that the porcelain tooth component 10 as a whole can be stably maintained in the installation position during long-term use without loosening or falling off.

[0037] The bracket 11 is provided with a plurality of micropores 18 which are completed by laser drilling. The micropores 18 can greatly increase the surface area of ​​the porcelain tooth component 10. When the bracket 11 is coated with adhesive, the adhesive can penetrate through the micropores 18, thereby being able to contact more surface areas. According to bonding theory, the bonding strength is proportional to the bonding area. Therefore, a larger bonding area means that a stronger interaction force can be formed between the adhesive and the bracket 11, thereby improving the penetration strength of the bonding.

[0038] The installation and use process of the porcelain tooth assembly 10:

[0039] 1. First, conduct a comprehensive examination of the patient's oral health status to ensure that there are no oral diseases or other factors that affect the restoration. Check the root of the tooth and the surrounding bone through X-rays to ensure that the installation position and supporting structure of the porcelain tooth component 10 are healthy. At the same time, design a suitable treatment plan based on the examination results and discuss the appropriate type, color and installation plan of the porcelain tooth component 10;

[0040] 2. Perform preparatory trimming according to the patient's tooth condition, and slightly polish the teeth in the repair area to lay the foundation for the bonding of the porcelain tooth component 10, ensuring that the porcelain tooth component 10 fits perfectly with the patient's oral cavity. At the same time, according to the patient's tooth color and oral characteristics, accurately select the color of the porcelain tooth component 10 to ensure that the teeth are natural and harmonious after repair;

[0041] 3. The bracket 11, bridge 14 and porcelain surface 16 can be tried in the oral cavity to put the structural parts in place in the edentulous area. The key points of the inspection are: the three structures can be smoothly put in place without looseness, and the rubber can be bitten with normal jaw force without looseness, the bracket 11 cannot be dislocated downward or upward and has no premature contact with the opposing teeth, no step is formed at the joint, the bevel is smooth and does not irritate the gums, and is more than 1 mm away from the gums;

[0042] 4. Clean the retention surface (bonding surface) of the abutment and etch it for 60 seconds, then rinse it with water for 60 seconds. At the same time, ensure that the retention surface of the abutment is thoroughly and carefully cleaned to avoid missing any part. This is because any small area of ​​the retention surface of the abutment may have dirt, plaque or other impurities if it is not thoroughly cleaned. These residual substances will affect the bonding effect between the restoration and the abutment, resulting in weak bonding and increasing the risk of loosening and falling off of the restoration;

[0043] 5. Apply a hydrophilic fluorine-containing photocuring adhesive or anticaries coating twice on the slightly moist bonding surface of the abutment, and blow it dry and evenly, and blow off the excess adhesive to avoid affecting the positioning of the structural parts. The hydrophilic fluorine-containing photocuring adhesive can better interact with the slightly moist surface of the abutment to form a stronger chemical bond and mechanical interlocking, which helps to improve the bonding strength between the restoration such as the porcelain tooth component 10 and the abutment, so that the restoration is more firmly attached to the abutment and reduces the risk of the restoration loosening or falling off.

[0044] 6. Apply a dual-curing adhesive with better toughness on the tooth surface and metal surface of the bonding surface, respectively, place them in place according to the diagram, tighten and fix them with screws 17, and check the corresponding jaw relationship. After the porcelain tooth component 10 is in place, use the matching tools to screw the screws 17 into the corresponding threaded holes 13, and gradually tighten them to make the porcelain tooth component 10 fit closely with the abutment tooth;

[0045] 7. Wipe off excess adhesive. The adhesive in the small gap of the cervical sanitary area can be blown away with an air gun. For the bonding surface with insufficient adhesive, low-viscosity adhesive can be infiltrated from the micropores 18. At the same time, light-curing material can be applied to cover the metal color of the screw 17.

[0046] 8. Use a super-strong visible light curing machine to irradiate the abutment teeth in multiple directions for 20 seconds twice. After the super-strong visible light enters the enamel and micropores 18, it can be scattered in the enamel to achieve the purpose of initial curing and positioning. After 20 minutes, 80% of the curing can be achieved due to the action of chemical initiators, and normal chewing function can be restored after 1 hour.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
