[0025] The utility model embodiment provides a kind of filling device for the shaping of bioceramic repair material, such as Figs. 1-2 As shown in the device includes filler handle 1, filling rod 2, filler head 3;

[0026] The filling rod 2 is movably arranged in the filler handle 1 to form a filler body;

[0027] The filler head 3 is connected with the filler handle 1 by the connecting part 4;

[0028] The filler head 3 is provided with a containing groove 31 (diameter: 3-5mm; depth: 2-3mm) and a shaping opening 32 (diameter 1-3mm; depth: 2-3mm), wherein the containing groove 31 is used to add bioceramic repair material, and the shaping opening 32 is used to shape and fill the material.

[0029] The utility model can place bioceramic repair material in the containing groove 31 of the filler head 3 in advance, then connect the head with the filler body, and repeatedly press the bioceramic repair material through the filling rod 2, shape the bioceramic repair material through the shaping opening 32, and place it in the pulp-exposed site, which is convenient for clinicians to operate.

[0030] The filler handle 1 includes a holding end 11 and a filling end 12, and the filling end 12 is rigidly connected with the filler head 3 through the connecting part 4.

[0031] The connecting part 4 can select a sterilizable metal screw retaining part, which can link the filler handle 1 and the filler head 3, and only the filler head 3 needs to be replaced after use, and the filler handle 1 can be used next time, and the filler head 3 can be repeatedly sterilized to achieve the purpose of one person one use sterilization.

[0032] The filling rod 2 includes a pressing end 21 and a filling end 22, the filling end 22 extends into the filler head 3 through the connecting part 4, and the pressing end 21 is arranged outside the filler handle 1.

[0033] Further, a reset assembly 23 is further included, which is arranged at the filling end 22 and located at the lower side of the connecting part 4.

[0034] The reset assembly 23 includes a sleeve rod 231, a fixed short rod 232 and a spring 233, the sleeve rod 231 is sleeved on the filling rod 2, the fixed short rod 232 is arranged at one side of the filling end 22, the spring 233 is sleeved on the fixed short rod 232, and the lower end of the spring 233 abuts against the upper end of the sleeve rod 231.

[0035] When the pressing end 21 is pressed down, the spring 233 is compressed, and at the same time, the blocking short rod prevents the filling rod 2 from excessively retreating, ensuring that the filling end 22 always remains within a certain position range. When the external force disappears, the spring 233 releases energy to push the filling rod 2 to reset.

[0036] The fixed short rod 232 plays a role in preventing the filling rod 2 from excessively retreating, and when the spring 233 pushes the sleeve rod 231 to move upward, the fixed short rod 232 limits the movement distance of the sleeve rod 231, thereby preventing the filling end 22 of the filling rod 2 from excessively retreating, ensuring the stability and reliability of the filling device.

[0037] During the filling process, the relative positions of the fixed short rod 232 and the sleeve rod 231 remain unchanged, and the spring 233 is compressed. When the user stops pressing the filling rod 2, the spring 233 will push the sleeve rod 231 to move upward due to its own elasticity, and then drive the filling end 22 of the filling rod 2 to retreat. In this way, the automatic reset of the filling rod 2 is realized, which is convenient for the next filling operation.

[0038] Further, a filler head connecting rod 24 is further included, which is arranged in the filler head 3 and abuts against the filling end 22 of the filling rod 2 at the lower end.

[0039] Specifically, the filler head 3 is in a circular arc shape, and the filler head connecting rod 24 is matched with the shape of the filler head 3.

[0040] The circular arc shape can better adapt to the natural curvature of teeth, especially the morphology of posterior teeth and complex areas, helping to ensure that the filling material can be uniformly and tightly attached to the tooth surface, improving the accuracy and sealing of filling.

[0041] The circular arc-shaped filler head can provide smoother transitions during shaping, reducing material accumulation and unevenness, and helping to achieve a more natural tooth appearance and better aesthetic results.

[0042] The filler head 3 can also be linear, and the shape of the filler head connecting rod 24 matches the filler head 3.

[0043] The linear shape of the filler head 3 is designed to be simple and direct, making it easy for doctors to quickly and accurately operate during filling, helping to shorten treatment time and improve work efficiency.

[0044] The linear shape is more suitable for anterior teeth or relatively flat areas, as the tooth morphology in these areas is relatively simple and does not require complex curvature adaptation. Using a linear-shaped filler head in these areas can more effectively compact and shape the material.

[0045] The linear design allows doctors to more clearly perceive the distribution and compaction of the filling material during operation, helping doctors maintain higher control during treatment and ensuring the stability and reliability of the filling effect.

[0046] The filler head 3 is designed in a circular arc or linear shape, mainly based on tooth morphology, shaping ability, ease of operation, treatment area, and control. In actual application, doctors should choose the appropriate shape of the filler head 3 according to the specific situation of the patient and the treatment needs to achieve the best treatment effect.

[0047] The accommodation groove 31 is the space formed between the shaping opening 32 of the filler head 3 and the filler head connecting rod 24.

[0048] The size of the shaping opening 32 (diameter: 1-3mm; depth: 2-3mm) in the radial direction is smaller than that of the accommodation groove 31 (diameter: 3-5mm; depth: 2-3mm).

[0049] By reducing the size of the shaping opening 32, the outflow amount and speed of the bioceramic restorative material can be more effectively controlled, ensuring that the material can be filled according to the predetermined shape and amount.

[0050] The smaller shaping opening 32 helps doctors to shape the material more finely during filling, resulting in a more accurate and natural tooth appearance.

[0051] Limiting the flow of material through the shaping opening 32 can reduce unnecessary material waste and improve the economy and efficiency of treatment.

[0052] In the working process, when the user needs to add bioceramic repair material into the filler head 3 and fill, first add an appropriate amount of bioceramic repair material into the accommodating groove 31 of the filler head 3. Then, by holding the holding end 11 of the filler handle 1, press the pressing end 21 of the filling rod 2 with the other hand. At this time, the filling end 22 of the filling rod 2 will penetrate through the connecting part 4 and extend into the filler head 3, compact and fill the bioceramic repair material through the filler head connecting rod 24, and finally push the shaped material out of the filler head 3 through the shaping opening 32.

[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
