Dental materials, also known as oral materials, are one of the biomedical materials used to repair defective teeth or to replace defective, missing dentitions, restoring their anatomical morphology, function and aesthetics. Dental materials are also used in medical treatments such as oral preventive care and correction of deformity. Dental materials can be classified into metallic materials, ceramic materials and polymeric resin materials according to their composition. The worldwide dental product market is estimated to be about $ 180 billion, with approximately 60% of the material share, by DENSPLY corporation. The output of Chinese false teeth in 2012 is 8650 ten thousand, which accounts for 60% of the world, and it is expected that the market of Chinese dental materials will reach 120 hundred million RMB by 2030.

Among them, the porcelain tooth in which the metal coping and the glaze layer are combined gradually becomes the mainstream of the industry.

The open end of the sizing component 120 is connected with the fixing base 110, the dental crown body 200 to be subjected to porcelain coating can be wrapped inside, and a gap is formed between the dental crown body 200 and the sizing component 120. Specifically, the upper porcelain gap 300 between the crown body 200 to be porcelain and the sizing assembly 120 is controlled to be between 2mm and 2.5 mm.

The fixing base 110 is provided with a protrusion 111, and the protrusion 111 is located in the shaping assembly 120 for fixing the crown body 200 to be applied with porcelain. The protrusion 111 matches the size of the hole of the gingival end of the crown body 200. In the process of applying the porcelain to the crown body 200 to be applied, the crown body 200 may be provided on the fixing base 110 to play a role of fixing the crown body 200. The protrusions 111 may be, but are not limited to, columnar structures. Preferably, the stationary base 110 is a plaster stationary base.

Specifically, the porcelain applying device 100 for porcelain teeth is not limited to a single denture, but may be modified according to the structure of multiple conjoined dentures. For example, there may be a plurality of protrusions 111 on the fixing base 110, and there are a plurality of matching fixing elements 120.

The shaping component 120 is provided with a flow guide channel 130 communicated with the upper porcelain cavity. The flow leader 130 is used to pass the porcelain powder fluid. Specifically, as shown in fig. 1, the molding assembly 120 includes a first molding block 121 and a second molding block 122, the first molding block 121 and the second molding block 122 are connected, and the first molding block 121 and the second molding block 122 may be, but are not limited to, bonded. The first and second shaped blocks 121 and 122 are engaged with the fixing base 110. Specifically, the first and second shaped blocks 121 and 122 are respectively bonded to the fixing base 110. The first and second shaping blocks 121 and 122 are respectively provided with a flow guide 130, and the flow guide 130 is arranged at one end of the first and second shaping blocks 121 and 122 corresponding to the occlusion end of the dental crown body 200 to be applied with porcelain, i.e. the end far away from the fixed base 110. Preferably, the exterior shape of the styling member 120 is square.

The outer shape of the styling member 120 is not limited and may be a regular geometric shape or an irregular shape. The external shapes of the first and second shaped blocks 121 and 122 may be the same or different. Preferably, the combined inner shape of the first and second shaping blocks 121 and 122 is identical to the shape of the crown body 200 to be applied. The first and second shaping blocks 121 and 122 are provided with a flow guide channel 130. Preferably, the flow guide 130 is arranged on the first and second shaped blocks 121 and 122 corresponding to the most distant position of the gingival end of the dental crown body 200 to be applied with porcelain, that is, the flow guide 130 is arranged at the first and second shaped blocks 121 and 122 corresponding to the most distant position of the gingival end from the occlusal end of the dental crown body 200 to be applied with porcelain. In the process of applying porcelain to the dental crown body 200, the dental crown body 200 is firstly disposed on the protrusion 111 of the fixing base 100, and then the first and second shaping blocks 121 and 122 are enclosed to wrap the dental crown body 200 therein.

The porcelain powder fluid enters the upper porcelain gap 300 through the flow guide 130 after being injected and extruded, and the porcelain powder fluid is filled in the upper porcelain gap 300 between the dental crown body 200 to be porcelain and the shaping assembly 120. When the porcelain device 100 of the porcelain tooth with the porcelain powder fluid filled in the upper porcelain gap 300 is used for porcelain baking, the porcelain powder fluid is solidified and formed, is combined with the dental crown body 200 together, and is combined with the dental crown body 200 together through high-temperature curing to form an integrated structure, so that the porcelain baking process is completed.

Specifically, the shaping block is a polylactic acid shaping block, a polyvinyl alcohol shaping block, a PLGA shaping block, a polybutylene adipate/terephthalate shaping block, a polyhydroxyalkanoate shaping block or a polybutylene succinate shaping block. In the using process of the ceramic applying device 100 of the porcelain tooth, the ceramic applying device injected with the ceramic powder fluid is placed into a porcelain oven for baking, the shaping block is further melted and volatilized, the ceramic powder fluid is heated, dried and solidified to be combined with the dental crown body 200, and finally the porcelain applying process is completed through the processes of temperature rise, heat preservation and the like. Therefore, the material of the shaping component 120 is preferably a plastic material with low melting point, environmental protection and no toxicity, and the plastic material volatilizes and disappears in the porcelain baking process, so that the problem of environmental pollution does not exist.

More specifically, the sizing assembly 120 may be obtained by 3D printing. The inner shape of the sizing assembly 120 is designed and printed according to the shape of the dental crown body 200 to be applied with porcelain, so that personalized customization can be realized to meet the requirements of different customers. The position of flow leader 130 may also be adjusted as desired during the 3D printing process. The shaping component 120 with the inner contour completely matched with the socket ditch outside the false tooth porcelain layer is manufactured by utilizing a plastic 3D printing technology, and the process of manually polishing the socket ditch after the porcelain baking process is omitted. The porcelain applying device 100 using the porcelain teeth can save about 7min of porcelain applying time for a single denture, and simultaneously, the problem of cracking of a porcelain layer caused by careless polishing is avoided.

The porcelain applying device 100 of the porcelain tooth performs a shaping function by utilizing the combination of the fixed base 110 and the shaping component 120. The thickness of the porcelain layer formed by the porcelain powder fluid on the dental crown body 200 is further controlled by controlling the size of the gap between the sizing assembly 120 and the dental crown body 200 to be porcelain. The porcelain feeding device 100 using the porcelain teeth can realize one-time forming, replaces the traditional manual brush porcelain feeding process, avoids the cracking of false tooth porcelain layers caused by careless polishing, greatly reduces forming risks and improves porcelain feeding efficiency.
