Description

Technical Field

[0001] This invention relates to the field of oral restoration technology, specifically to a surface treatment device for oral restorations. Background Technology

[0002] With social progress and economic development, modern people are paying increasing attention to oral health. All-ceramic restorations are becoming increasingly widely used in clinical practice due to their realistic aesthetic effects and good biocompatibility. The success of all-ceramic restorations depends on a reliable and strong bond between the porcelain and the resin. Currently, commonly used ceramic materials in clinical practice include glass ceramics and yttrium-stabilized tetragonal zirconia polycrystalline ceramic materials (hereinafter referred to as zirconia). Due to the inherent characteristics of ceramic materials, their bonding effect is relatively poor, and special treatment is required to achieve the bonding strength required for clinical use, especially for zirconia materials. Therefore, how to simply and effectively improve the bonding performance of ceramic materials has become an urgent problem to be solved in dental restorative treatment.

[0003] To improve the bonding performance between zirconia and glass-ceramics, the main clinical method is to use polishing equipment to smooth the surface of dental prostheses, resulting in a smooth and rounded surface. Higher surface smoothness and a more even finish lead to a stronger bond. Currently, the primary method involves pre-treating the material surface with chemical reagents before bonding. There are some differences in the pre-treatment processes for the two materials. For zirconia, a primer is required during pre-treatment; a representative primer is Z-PRIMERPLUS manufactured by BISCO in the United States. After pre-treatment, the shear bond strength of zirconia can reach approximately 20 MPa. For glass-ceramics, the pre-treatment process is relatively more complex. Furthermore, chemical etching methods are difficult to control in terms of reagent concentration and duration, are cumbersome, and result in highly unstable treatment effects, a very high defect rate, and increased material costs. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by the present invention is as follows: a surface treatment device for dental prostheses, comprising: a polishing drive frame, a polishing cylinder, a mounting head, and a drive motor. A bearing sleeve is fixedly installed inside the polishing drive frame. A moving spindle fixedly connected to one end of the mounting head is rotatably sleeved on the surface of the bearing sleeve. A deflection block is fixedly sleeved on the surface of the moving spindle. A coupling assembly rotatably installed inside the polishing drive frame is fixedly connected to the output end of the drive motor. A circular hole is opened on the surface of the deflection block and it is movably sleeved on the other end of the coupling assembly. A liner is provided on the inner side of the polishing cylinder, and the interior of the polishing cylinder is filled with steel grit particles.

[0006] In a preferred embodiment, the present invention may be further configured such that: the coupling assembly includes a first rotating shaft, a second swing shaft, and a driving disk and a driven disk respectively fixed to the ends of the first rotating shaft and the second swing shaft; the driving disk and the driven disk are provided with a plurality of meshing teeth on their relatively inner sides; and the surfaces of the first rotating shaft and the second swing shaft are provided with bearing brackets and rotatably mounted inside the polishing drive frame.

[0007] Furthermore, one end of the first rotating shaft is fixedly connected to the output end of the drive motor, the second swing shaft is arranged at an angle, and the diameter of the circular hole on the surface of the deflection block is larger than the diameter of the second swing shaft and is movably sleeved on the outside of the second swing shaft, so that the deflection block swings during the transmission of the coupling assembly and the deflection block.

[0008] By adopting the above technical solution, the drive motor and the deflection block are transmitted through the coupling assembly, and the reciprocating oscillation and the trembling motion of the deflection block are realized respectively under the kinetic energy transmission of the coupling assembly.

[0009] In a preferred embodiment, the present invention can be further configured such that: the number of the teeth is several and they are distributed in a circular pattern on the surfaces of the driving disk and the driven disk, and the cross-section of the teeth is a right-angled triangle.

[0010] By adopting the above technical solution, the active disc reverses and intermittently contacts the surface of the driven disc. Under the vibration movement, the density difference between the liner and the dental prosthesis makes the dental prosthesis gradually float on the surface of the steel grit particles, making it easier to remove.

[0011] In a preferred embodiment, the present invention can be further configured such that: the mounting head includes a clamp, a retaining rod, and a screw chuck, the clamp and the retaining rod are perpendicular to each other and welded together, one end of the clamp is provided with a threaded hole, the screw chuck is threaded onto the surface of the clamp, and a clamping plate is movably mounted on one end of the clamp, thereby clamping the polishing cylinder using the clamp and the retaining rod, which facilitates the fixation of the polishing cylinder.

[0012] In a preferred embodiment, the present invention can be further configured such that: the polishing cylinder is a barrel-shaped structure with a sealed cover, and the surface of the liner plate is provided with a plurality of protruding structures.

[0013] Furthermore, the steel grit particles are one or more mixtures of sponge sand, diamond sand, corundum, and garnet sand, and the filling amount of the steel grit particles is one-third of the volume of the polishing cylinder.

[0014] By adopting the above technical solution, the dental prosthesis is placed inside the polishing cylinder and subjected to electric-driven disordered movement. The repeated impact of steel grit particles with the surface of the dental prosthesis eliminates the tiny protrusions on the surface of the dental prosthesis, creating a smooth and glossy surface.

[0015] The beneficial effects achieved by this invention are as follows:

[0016] 1. In this invention, by setting up a physical polishing method, the dental prosthesis is put into the polishing cylinder for electrically driven disordered movement. The repeated impact of steel grit particles with the surface of the dental prosthesis eliminates the tiny protrusions on the surface of the dental prosthesis, creating a smooth and glossy surface. The surface treatment intensity of the dental prosthesis can be controlled by adjusting the particle size of the steel grit particles and the working time. The operation is simple and highly stable.

[0017] 2. In this invention, by setting a novel coupling drive structure, the forward and reverse drives of the drive motor are used to realize the reciprocating oscillation and the vibrating motion of the deflection block under the kinetic energy transmission of the coupling assembly. Under the reciprocating oscillation condition, the surface of the dental prosthesis inside the polishing cylinder is polished. Under the vibrating motion, the density difference between the liner and the dental prosthesis causes the dental prosthesis to gradually float on the surface of the steel grit particles, making it easy to remove. The whole operation is simple and quick, greatly improving the efficiency of dental prosthesis surface treatment. Attached Figure Description

[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of a dental prosthesis surface treatment device provided by the present invention.

[0031] Example 1

[0032] Combination Figure 1 , Figure 2 , Figure 4 As shown, the present invention provides a surface treatment device for dental prostheses, comprising: a polishing drive frame 100, a polishing cylinder 200, a mounting head 300, and a drive motor 400. A bearing sleeve 110 is fixedly installed inside the polishing drive frame 100. A moving spindle 120 fixedly connected to one end of the mounting head 300 is rotatably sleeved on the surface of the bearing sleeve 110. A deflection block 130 is fixedly sleeved on the surface of the moving spindle 120. A coupling assembly 140 rotatably installed inside the polishing drive frame 100 is fixedly connected to the output end of the drive motor 400. A circular hole is opened on the surface of the deflection block 130 and it is movably sleeved on the other end of the coupling assembly 140. A liner 210 is provided on the inner side of the polishing cylinder 200, and the interior of the polishing cylinder 200 is filled with steel grit particles 220.

[0033] Example 2

[0034] Combination Figure 5 In this embodiment, the coupling assembly 140 includes a first rotating shaft 141, a second swing shaft 142, and a driving disk 143 and a driven disk 144 respectively fixed to the ends of the first rotating shaft 141 and the second swing shaft 142. The driving disk 143 and the driven disk 144 are provided with a plurality of meshing teeth 145 on their relatively inner sides. The surfaces of the first rotating shaft 141 and the second swing shaft 142 are provided with bearing brackets and are rotatably mounted inside the polishing drive frame 100. One end of the first rotating shaft 141 is fixedly connected to the output end of the drive motor 400. The second swing shaft 142 is arranged at an inclination. The diameter of the circular hole on the surface of the deflection block 130 is larger than the diameter of the second swing shaft 142 and is movably sleeved on the outside of the second swing shaft 142, so that the deflection block 130 swings during the transmission of the coupling assembly 140 and the deflection block 130.

[0035] Specifically, the drive motor 400 and the deflection block 130 are transmitted through the coupling assembly 140. Under the kinetic energy transmission of the coupling assembly 140, the reciprocating oscillation and the vibration movement of the deflection block 130 are realized respectively. Under the reciprocating oscillation condition, the surface of the oral prosthesis inside the polishing cylinder 200 is polished. Under the vibration movement, the density difference between the liner 210 and the oral prosthesis causes the oral prosthesis to gradually float on the surface of the steel grit particles 220.

[0036] In this embodiment, the number of teeth 145 is several and they are distributed in a circular pattern on the surfaces of the driving disk 143 and the driven disk 144. The cross-section of the teeth 145 is a right-angled triangle.

[0037] Specifically, the active disc 143 reverses and intermittently contacts the surface of the driven disc 144. Under the vibration movement, the density difference between the liner 210 and the dental prosthesis causes the dental prosthesis to gradually float above the surface of the steel grit particles 220 for easy removal.

The screw chuck 330 is threaded onto the surface of the clamp 310. A clamping plate is movably mounted on one end of the clamp 310. The clamp 310 and the retaining rod 320 are used to clamp the polishing cylinder 200, which facilitates the fixation of the polishing cylinder 200.

[0040] In this embodiment, the polishing cylinder 200 is a barrel-shaped structure with a sealed cover, and the surface of the liner 210 is provided with several protruding structures.

[0041] Furthermore, the steel grit 220 is one or more of sponge sand, diamond sand, corundum and garnet sand, and the filling amount of steel grit 220 is one-third of the volume of the polishing cylinder 200.

[0042] Specifically, the dental prosthesis is placed inside the polishing cylinder 200 and subjected to electrically driven disordered movement. The repeated impact of steel grit 220 with the surface of the dental prosthesis eliminates the tiny protrusions on the surface of the dental prosthesis, creating a smooth and glossy surface. The surface treatment intensity of the dental prosthesis can be controlled by adjusting the particle size of the steel grit 220 and the working time. The operation is simple and highly stable.
