[0002] Composite resin teeth are dental restorations made of specific materials and are primarily used to replace missing teeth.

[0003] In existing technologies, the antibacterial testing of resin teeth mainly involves observing the distribution of bacteria on the resin teeth using an optical microscope. This observation can only make a qualitative judgment on the antibacterial performance of the resin teeth, but cannot provide a quantitative analysis. To overcome the above-mentioned technical shortcomings, we propose a composite resin tooth antibacterial performance testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a composite resin tooth antibacterial performance testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A base is fixedly installed on the bottom inner side of the composite resin tooth testing box, and a testing glass is placed on the upper side of the base. A back plate is installed on the rear side of the composite resin tooth testing box, and an antibacterial testing mechanism is installed on the back plate. The antibacterial testing mechanism includes a lampshade, which is fixedly installed on the inner side of the back plate. A supplementary light is fixedly installed around the inner periphery of the lampshade. Two electron optical microscopes are symmetrically fixedly installed at the middle position of the inner side of the lampshade. A control host is fixedly installed on the outer side of the back plate. A transmission cable connects the control host and the electron optical microscopes. The control host is equipped with operation buttons and a display screen.

[0007] Preferably, the back plate is screwed to the back of the composite resin dental testing box at the four corners.

[0008] Preferably, two placement slots are symmetrically formed on the upper side of the base, and a matching rubber ring is installed around the inner perimeter of the placement slot, the matching rubber ring abutting against the outer wall of the test glass.

[0009] Preferably, a handle is fixedly connected to the side wall of the testing glass.

[0010] Preferably, the composite resin dental testing box has a door rotatably mounted on the front side, and the door is equipped with a handle.

[0011] Preferably, the composite resin dental testing box is provided with a stirring mechanism inside. The stirring mechanism includes a housing, a drive motor is fixedly installed in the middle of the housing, a central gear is fixedly installed on the output end of the drive motor, a rotating shaft is symmetrically rotatably installed inside the housing, a side gear is fixedly installed on the rotating shaft, the side gear meshes with the central gear, the rotating shaft rotates through to the lower side of the housing and a plurality of stirring rods are fixedly installed at the lower end of the rotating shaft, and flippers are fixedly installed at the ends of the stirring rods.

[0012] Preferably, neither the central gear nor the side gear contacts the inner wall of the chassis, and the position of the shaft center corresponds to the position of the center of the placement slot.

[0013] Preferably, an electric telescopic rod and a stabilizing telescopic rod are fixedly installed between the upper side of the chassis and the top of the inner side of the composite resin dental testing box, and the stabilizing telescopic rod is symmetrically distributed on both sides of the electric telescopic rod.

[0014] Compared with related technologies, the composite resin tooth antibacterial performance testing device proposed in this utility model has the following beneficial effects:

[0015] In this invention, a composite resin tooth antibacterial performance testing device is described. Through an antibacterial testing mechanism, artificial teeth and composite resin teeth, cultured with bacterial colonies under the same conditions, are placed into a testing glass cup of this invention, submerged in purified water, and then stirred and mixed using a stirring mechanism. Subsequently, an electron optical microscope within the antibacterial testing mechanism observes the mixed solution in the testing glass cup. The electron optical microscope feeds back the observation results to the control host. Microscopic electronic images of the solutions from both the artificial teeth and composite resin teeth are simultaneously displayed on the screen. Under magnification, the bacteria within the solution are distributed in the feedback electronic image, appearing in a darker color. The calculation program in the control host analyzes the distribution and quantity of bacteria in the two solutions, calculating the ratio of the bacterial content in the composite resin tooth mixed solution to the bacterial content in the artificial tooth mixed solution. This allows for a specific determination of the antibacterial performance of the composite resin tooth, enhancing the practicality of this invention. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4 A composite resin tooth antibacterial performance testing device includes a composite resin tooth testing box 1, a base 2 fixedly installed on the bottom inner side of the composite resin tooth testing box 1, a testing glass 5 placed on the top side of the base 2, a back plate 7 installed on the rear side of the composite resin tooth testing box 1, and an antibacterial testing mechanism 8 installed on the back plate 7; the antibacterial testing mechanism 8 includes a lampshade 81, which is fixedly installed on the inner side of the back plate 7, and the four corners of the back plate 7 are screwed to the back of the composite resin tooth testing box 1; supplementary lights 82 are fixedly installed on the inner periphery of the lampshade 81; two electron optical microscopes 83 are symmetrically fixedly installed in the middle position of the inner side of the lampshade 81; a control host 85 is fixedly installed on the outer side of the back plate 7; a transmission cable 84 connects the control host 85 and the electron optical microscopes 83; and the control host 85 is equipped with operation buttons 86 and a display screen 87.

[0023] To further clarify, the composite resin dental testing box 1 is a box used for testing composite resin teeth, which are dental restorations made of composite resin materials.

[0024] In this method, two placement slots 3 are symmetrically opened on the upper side of the base 2, and a matching rubber ring 4 is installed around the inner perimeter of the placement slot 3. The matching rubber ring 4 abuts against the outer wall of the test glass 5.

[0025] With the above-described configuration, the matching rubber ring 4 installed around the inner perimeter of the placement groove 3 ensures that when the test glass 5 is placed inside the placement groove 3, the bottom outer wall of the test glass 5 will be resisted by the matching rubber ring 4, thus allowing the test glass 5 to be stably placed inside the placement groove 3.

[0026] In this method, a handle is fixedly connected to the side wall of the glass 5.

[0027] The above-described design, including the handle, facilitates the handling and placement of the testing glass 5.

[0028] In this method, a door 11 is rotatably mounted on the front side of the composite resin dental testing box 1, and a handle is installed on the door 11.

[0029] By setting up the door 11 as described above, the internal testing environment of the composite resin dental testing box 1 is sealed, avoiding interference from bacteria on the outside of the composite resin dental testing box 1 during the testing process.

[0030] In this method, a stirring mechanism 6 is provided inside the composite resin dental testing box 1. The stirring mechanism 6 includes a housing 61. A drive motor 62 is fixedly installed in the middle of the inner side of the housing 61. A central gear 63 is fixedly installed on the output end of the drive motor 62. A rotating shaft 64 is symmetrically rotated inside the housing 61. A side gear 65 is fixedly installed on the rotating shaft 64. The side gear 65 meshes with the central gear 63. The rotating shaft 64 rotates through to the lower side of the housing 61, and a number of stirring rods 66 are fixedly installed at the lower end of the rotating shaft 64. A webbed foot 67 is fixedly installed at the end of the stirring rod 66.

[0031] With the above configuration, when the stirring rod 66 and the cup shaft 64 rotate, the webbed feet 67 at its bottom will rotate accordingly, which can fully mix the liquid in the detection glass 5.

[0032] In this configuration, neither the central gear 63 nor the side gear 65 contacts the inner wall of the housing 61, and the axis of the rotating shaft 64 corresponds to the center of the placement slot 3.

[0033] With the above-mentioned setup, the center position of the rotating shaft 64 corresponds to the center position of the placement groove 3, thereby ensuring that when the stirring rod 66 and the flipper 67 are inserted into the inner side of the test glass 5 and rotated, the eccentric force generated by the rotating water flow during stirring is small, and thus the test glass 5 will not shake due to stirring.

[0034] In this method, an electric telescopic rod 9 and a stabilizing telescopic rod 10 are fixedly installed between the upper side of the chassis 61 and the top of the inner side of the composite resin dental testing box 1. The stabilizing telescopic rod 10 is symmetrically distributed along both sides of the electric telescopic rod 9.

[0035] With the above-described configuration, the stabilizing telescopic rods 10 on both sides make the electric telescopic rods 9 more stable when driving the entire stirring mechanism 6 to move up and down.

[0036] The working principle of the composite resin tooth antibacterial performance testing device provided by this utility model is as follows:

[0037] In use, ordinary artificial teeth and composite resin teeth, cultured under the same laboratory conditions, are placed into the test glass 5. Purified water is added to the test glass 5. The glass containing the ordinary artificial teeth and composite resin teeth is placed inside the placement slot 3, with its bottom abutting against the fitting ring 4. The door is then closed, and the electric telescopic rod 9 is activated, causing the stirring rod 66 and the webbed feet 67 at the end of the stirring rod 66 to extend into the test glass 5. The drive motor 62 is then activated, driving the central gear 63 to rotate. The central gear 63 synchronously drives the meshing side gears 65 on both sides to rotate, thereby causing the two rotating shafts 64 to rotate at the same speed. Thus, the stirring rod 66 and the webbed feet 67 in the glass containing the ordinary artificial teeth and composite resin teeth have consistent stirring efficiency, and the stirring is complete. Afterwards, the drive motor 62 is turned off, and the electric telescopic rod 9 drives the stirring rod 66 and the flipper 67 to return to above the test glass 5. Subsequently, the electron optical microscope 83 observes the mixed solution in the test glass 5 and feeds back the observation results to the control host 85. The microscopic electronic images of the solutions of the artificial tooth and the composite resin tooth are displayed simultaneously on the display screen 87. The bacteria mixed in the solution will be distributed on the feedback electronic image under the magnification display, and their color is darker. At this time, the calculation program in the control host 85 analyzes the distribution of bacteria in the two sets of solutions and calculates the ratio of the bacterial content in the mixed solution of the composite resin tooth to the bacterial content in the mixed solution of the artificial tooth, thus specifically obtaining the antibacterial performance of the composite resin tooth.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
