[0002] In the fields of oral restoration and bonding, the performance evaluation of resin materials (such as tightness and microleakage) is an important factor affecting clinical applications. Traditional experimental methods usually adopt manual operations, that is, acid etching, rinsing, drying, coating adhesives, coating resins, and photocuring are carried out on samples one by one. This method is not only time-consuming and laborious, but also easily affects the repeatability and reliability of experimental results due to human operation errors. In addition, the experimental period of a single sample is long, and it is difficult to achieve large-scale data accumulation, which limits the efficient screening and comparative analysis of different resin materials.

[0003] In the prior art, traditional in vitro tooth experimental methods usually can only conduct experiments on a single tooth or a small number of teeth simultaneously. When dealing with a large number of samples, there are problems of low efficiency, cumbersome operation, and insufficient standardization, and it is difficult to ensure the consistency and repeatability of the experiments. Therefore, it is particularly important to develop a device that can efficiently and standardly conduct batch filling experiments. Summary of the Invention

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment. This embodiment provides an experimental device for the performance of oral restoration materials, as Figure 1 and Figure 7 shown, including a base 2. A recessed portion is recessed downward on the upper end surface of the base 2. An annular spacer 21 is fixed to the inner bottom wall of the recessed portion. An annular liquid storage cavity is formed between the outer wall of the annular spacer 21 and the inner side wall of the recessed portion. The annular liquid storage cavity is filled with a cleaning liquid, and a lifting plate 22 is arranged in the annular liquid storage cavity in a sliding and lifting manner.

[0032] A plurality of positioning tags 24 are vertically fixed to the upper end surface of the lifting plate 22; it also includes an extracted tooth 3 fixedly inserted on the positioning tags 24, as Figure 1 and Figure 2 shown. A plurality of extracted teeth 3 are embedded on the plurality of positioning tags 24. Here, the positioning tags 24 are set as a rectangular structure, and a spike portion is provided at the top. Holding the extracted tooth 3 and pressing it downward along the spike portion can sleeve the extracted tooth 3 on the positioning tag 24, ensuring that the extracted tooth 3 does not shake when testing the extracted tooth 3, and guaranteeing the effective progress of the test. Therefore, by arranging a plurality of extracted teeth 3 arranged in an annular structure on the lifting plate 22, experimental tests on multiple extracted teeth 3 in the same state can be carried out at one time. The multiple extracted teeth 3 can be under the same standardized experimental conditions, ensuring the consistency and repeatability of the experiment, improving the experimental efficiency, avoiding large errors caused by multiple single experiments, and thus accelerating the research and development and performance evaluation process of resin materials.

[0033] Specifically, a blocking portion extends radially along the top end of the annular spacer 21. The outer wall of the annular spacer 21 is slidably sleeved with a lifting plate 22 and a second spring 25 located below the lifting plate 22. One end of the second spring 25 is fixedly connected to the bottom wall of the lifting plate 22, and the other end is connected to the bottom wall of the annular liquid storage cavity. The elastic force of the second spring 25 is used to constantly press the lifting plate 22 against the bottom wall of the blocking portion, ensuring that the upper end surface of the lifting plate 12 is flush with the upper end surface of the base 2. When pressing the lifting plate 22 downward, the second spring 25 is compressed, and the lifting plate 22 can fall along the annular liquid storage cavity and approach the inner bottom wall of the cavity, and the extracted tooth 3 sleeved on the positioning tag 24 can be dropped into the annular liquid storage cavity and immersed below the liquid level of the cleaning liquid to achieve the cleaning operation.

[0034] It also includes a top seat 1 located directly above the base 2. The top seat 1 can be rotationally adjusted, as Figure 5As shown, specifically: the inner bottom wall of the recessed portion is threadedly connected with a support sleeve 18, and the upper end of the support sleeve 18 is slidably plugged with a rotating rod 17, and a spring 113 located on the bottom wall of the rotating rod 17 is provided in the support sleeve 18, and the top seat 1 is rotatably arranged on the upper end of the rotating rod 17, and horizontal force is applied along the radial side wall tangent of the top seat 1, so that the upper end surface of the rotating rod 17 can be rotated. One end of the spring 113 is fixedly connected to the bottom wall of the rotating rod 17, and the other end is fixedly connected to the inner bottom wall of the support sleeve 18. The elastic force of the spring 113 is used to push the rotating rod 17 upward in real time to ensure that the top seat 1 is vacant relative to the base 2. In addition, the support sleeve 18 is threadedly connected to the inner bottom wall of the recessed portion, and the support sleeve 18 is rotated in the opposite direction to disassemble and detach the top seat 1, so that it can be disassembled and cleaned after the experiment.

[0035] At the same time, if Figure 1 and Figure 3 As shown, multiple storage tubes 14 are fixed at the edge of the bottom wall of the top seat 1, and a feeding hole 112 is opened on the upper end surface of the top seat 1 to communicate with the upper end opening of the storage tube 14. A pusher extending into the storage tube 14 is inserted in the feeding hole 112. The pusher includes a rubber plug 19 slidably inserted in the storage tube 14 and a push rod 13 fixed at the upper end of the rubber plug 19. The push rod 13 extends out of the tube mouth of the storage tube 14 and the feeding hole 112, and extends to the upper position of the feeding hole 112. The corresponding experimental reagent is filled into the storage tube 14 from the opening of the feeding hole 112, and then the rubber plug 19 at the bottom end of the push rod 13 is inserted into the storage tube 14. In this way, the push rod 13 is pressed downward to squeeze the rubber plug 19 along the corresponding experimental reagent in the storage tube 14 from the bottom end opening to the surface wall of the corresponding soft coating roller 16. And the bottom end opening of the storage tube 14 is a narrow opening to avoid excessive overflow of the experimental reagent and waste.

[0036] Preferably, the reagents used in the experiment here include adhesive, acid etchant (37% phosphoric acid) and resin. For this purpose, three storage tubes 14 are provided, one of which is used to store adhesive, another is used to store acid etchant for acid etching, and another is used to store resin to be brushed. At the same time, a soft paint roller 16 is provided just below the bottom opening of the storage tube 14. Isolation plates 15 are fixedly provided at both ends of the axial direction of the soft paint roller 16. The gap between the two isolation plates 15 is the brushing gap. A suspension rod is connected between the outer wall of the isolation plate 15 and the outer wall of the storage tube 14. The two isolation plates 15 and the soft paint roller 16 constitute a brushing structure, and are arranged below the bottom opening of the storage tube 14 through the suspension rod. By pressing the push rod 13, the corresponding experimental reagent is squeezed out from the bottom opening of the storage tube 14 to the surface wall of the corresponding soft paint roller 16 using the rubber stopper 19.

[0037] When the top seat 1 rotates, multiple storage tubes 14 move in an annular motion trajectory. The coating soft roller 16 rotates successively past multiple extracted teeth 3. The radial bottom wall of the coating soft roller 16 contacts the crown of the extracted tooth 3. Two isolation discs 15 pass by the extracted tooth 3, and the inner side wall of the isolation disc 15 contacts the side wall of the crown edge of the extracted tooth 3, so as to coat the surface wall and the edge side wall of the crown of the extracted tooth 3 with the experimental reagent.

[0038] During the experiment, first, nest multiple extracted teeth 3 on multiple positioning tags 24 distributed in an annular structure. Subsequently, apply force along the tangential direction of the radial side wall of the top seat 1, and rotate the top seat 1 on the upper end surface of the rotating rod 17, driving the storage tube 14 to move on the annular trajectory. First, press the push rod 13 in the storage tube 14 filled with acid etchant. The rubber plug 19 is pressed down, and the acid etchant is extruded from the bottom opening of the storage tube 14 onto the surface wall of the coating soft roller 16. The coating soft roller 16 rotates successively past multiple extracted teeth 3. The radial bottom wall of the coating soft roller 16 contacts the crown of the extracted tooth 3. Two isolation discs 15 pass by the extracted tooth 3, and the inner side wall of the isolation disc 15 contacts the side wall of the crown edge of the extracted tooth 3, so as to coat the surface wall and the edge side wall of the crown of the extracted tooth 3 with the acid etchant and perform the acid etching operation on the crown.

[0039] After acid washing, press down the lifting disc 22, and the second spring 25 is compressed. The lifting disc 22 can fall along the annular liquid storage cavity and approach the bottom wall of the cavity, and the extracted tooth 3 sleeved on the positioning tag 24 can be dropped into the annular liquid storage cavity and immersed below the cleaning liquid surface to realize the cleaning of the extracted tooth 3 after acid washing.

[0040] After cleaning, release the pressed-down lifting disc 22, and use the elastic force of the second spring 25 to lift the lifting disc 22, so that the extracted tooth 3 is separated from the cleaning liquid. Subsequently, let it stand for half a minute to 2 minutes. After the cleaning liquid on the surface wall of the extracted tooth 3 dries, press the push rod 13 in the storage tube 14 filled with the adhesive. The rubber plug 19 is pressed down, and the adhesive is extruded from the bottom opening of the storage tube 14 onto the surface wall of the coating soft roller 16. The coating soft roller 16 rotates successively past multiple extracted teeth 3. The radial bottom wall of the coating soft roller 16 contacts the crown of the extracted tooth 3. Two isolation discs 15 pass by the extracted tooth 3, and the inner side wall of the isolation disc 15 contacts the side wall of the crown edge of the extracted tooth 3, so as to coat the surface wall and the edge side wall of the crown of the extracted tooth 3 with the adhesive.

[0041] After the application of the adhesive is completed, press the push rod 13 in the storage tube 14 filled with the bonding resin. The rubber plug 19 is pressed down, and the bonding resin is extruded from the bottom opening of the storage tube 14 onto the surface wall of the coating soft roller 16. The coating soft roller 16 rotates successively past multiple extracted teeth 3. The radial bottom wall of the coating soft roller 16 contacts the crown of the extracted tooth 3. Two isolation discs 15 pass by the extracted tooth 3, and the inner side wall of the isolation disc 15 contacts the side wall of the crown edge of the extracted tooth 3, so as to coat the surface wall and the edge side wall of the crown of the extracted tooth 3 with the bonding resin.

[0042] Finally, on the side wall of this end of the top seat 1 where the ventilation mesh hole 110 is located, there is an ultraviolet lamp tube 111 with an annular structure. At the same time, a rechargeable lithium battery is built into the top seat 1 to supply power to the ultraviolet lamp tube 111, and the ultraviolet lamp tube 111 is used to perform light curing operation on the in vitro tooth 3 coated with resin.

[0043] In summary, this experimental device can realize the sequential progress of acid etching and rinsing, drying, coating the adhesive, bonding resin, and light curing according to the experimental steps.

[0044] In this embodiment, it needs to be further explained that the coating soft roller 16 is a cylindrical rod made of PVC plastic, and the outer wall of the cylindrical rod is wrapped with a sponge sleeve; the sponge sleeve has adsorption property and has adsorption property corresponding to the acid cleaning solution, adhesive or resin. When contacting the crown of the in vitro tooth 3, it can be brushed on the surface wall and the edge side wall of the crown of the in vitro tooth 3. At the same time, the isolation disc 15 here is made of fluororubber material and has hardness. However, compared with the metal material, its hardness has a reversible deformation characteristic. The purpose of this move is to avoid the isolation disc 15 being too hard and causing damaging extrusion force to the in vitro tooth 3 when contacting the in vitro tooth 3.

[0045] Furthermore, as Figure 6 shown, on the upper end face of the top seat 1, there are two air storage cavities located on the side of the feeding port and recessed downward. The air storage cavities are distributed in an arc-shaped structure. The bottom wall of the air storage cavity is provided with ventilation mesh holes 110, and the ventilation mesh holes 110 are located directly above the lifting disc 22. At the same time, a cover 11 is threadedly connected to the upper end face of the top seat 1. The upper end face of the cover 11 extends upward with a storage extension part 12. The storage extension part 12 has a hollow structure, and a motor is fixed to the inner top wall of the hollow structure. The output end of the motor is connected with a fan blade 114. When the cover 11 is screwed onto the upper end face of the top seat 1, the fan blade 114 is located in the recessed part. The lithium battery built into the top seat 1 supplies power to the motor, driving the fan blade 114 to rotate in the recessed part. At the same time, after the cover 11 covers the upper end face of the top seat 1, the opening above the recessed part is closed. Then the wind generated by the rotation of the fan blade 114 will be blown out through the ventilation mesh holes 110 and aimed at the surface wall of the in vitro tooth 3 after being cleaned to blow air, accelerating its drying speed.

[0046] In addition, during the experiment, in order to prevent the base 2 from shaking when the top seat 1 is rotated, a plurality of rubber suction cups 23 are provided at the edge position of the bottom wall of the base 2. The plurality of rubber suction cups 23 are placed on the experimental table and sucked to ensure that the base 2 does not shake due to the rotation of the top seat 1, ensuring the effective progress of the experiment of brushing the experimental reagent.
