Abstract
Description
Technical Field
[0001] This utility model relates to the field of zirconia porcelain tooth polishing, and more specifically, to a zirconia porcelain tooth polishing device. Background Technology
[0002] In the field of dental restoration, zirconia porcelain teeth are widely used due to their excellent mechanical properties, good biocompatibility, and aesthetics.
[0003] However, after the zirconia porcelain crown is made, its surface and shape often need to be finely polished to achieve the ideal fit and aesthetic effect. The polishing of zirconia porcelain crowns is usually done externally. External polishing can use professional high-precision dental polishing equipment. These devices are usually equipped with precision grinding heads and advanced control systems, which can accurately control the angle, force and depth of polishing. Professional external polishing equipment has greater power and relatively faster polishing speed.
[0004] However, some dentists use their fingers to hold the zirconia crowns while grinding them with a grinding device. During prolonged, high-intensity grinding, finger fatigue and tremors can occur, leading to decreased grinding precision. Direct contact between the fingers and the zirconia crown may increase the risk of cross-infection, especially without adequate sterilization. Wearing gloves makes it difficult to control the gripping force, resulting in uneven grinding and affecting the uniformity and aesthetics of the restoration. Therefore, inventing a zirconia crown grinding device to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a zirconia porcelain tooth polishing device, which aims to improve the problem that finger fatigue and tremors are easy to occur when using fingers to hold and polish, resulting in a decrease in polishing accuracy, and the direct contact between fingers and zirconia porcelain teeth may increase the risk of cross-infection.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a zirconia porcelain tooth polishing device, comprising...
[0029] Zirconia tooth 100, which is a zirconia tooth to be polished; polishing positioning mechanism 200, which includes a clamping assembly 220, which includes a mounting plate 221, a first clamping plate 223 and a second clamping plate 224 are hinged to the middle of the mounting plate 221, the zirconia tooth 100 is located in the middle of the first clamping plate 223 and the second clamping plate 224, and a transmission handle 229 is respectively driven hinged to the outer side of the first clamping plate 223 and the second clamping plate 224; the polishing positioning mechanism 200 also includes a mounting assembly 210, which is located at the bottom of the clamping assembly 220 and is drivenly connected to the clamping assembly 220.
[0030] The polishing and positioning mechanism 200 uses a non-contact clamping method, avoiding direct contact between the dentist's fingers and the zirconia porcelain teeth, thus reducing the risk of cross-infection. At the same time, the polishing and positioning mechanism 200 is also easier to clean and disinfect, meeting the hygiene requirements of oral medicine.
[0031] Please see Figure 4 and Figure 5Limiting plates 222 are fixedly connected to the upper and lower sides of the mounting plate 221 respectively. One end of the first clamping plate 223 and the second clamping plate 224 are connected by a concave-convex cross connection. A limiting rod 226 is provided through the concave-convex connection of the first clamping plate 223 and the second clamping plate 224. The two ends of the limiting rod 226 are respectively limited to rotate through the limiting plate 222.
[0032] A tooth squeezing plate 225 is fixedly connected to one end of the first clamping plate 223 and the second clamping plate 224 away from the limiting rod 226. Both the first clamping plate 223 and the second clamping plate 224, along with the tooth squeezing plate 225, are arc-shaped to facilitate clamping the zirconia porcelain tooth. The first clamping plate 223 and the second clamping plate 224, together with the tooth squeezing plate 225, form an ellipse. The side view of the tooth squeezing plate 225 is an isosceles triangle. The smaller size of the apex of the isosceles triangle helps to clamp the zirconia porcelain tooth while avoiding interference with polishing.
[0033] Mounting plate 221 is fixedly mounted on the outer side of first clamping plate 223 and second clamping plate 224, with fixing rods 227 respectively. A transmission plate 228 is fixedly connected to the top of the fixing rods 227. A transmission handle 229 is threaded through the middle of the transmission plate 228. One end of the transmission handle 229 is connected to the outer side of the first clamping plate 223 and second clamping plate 224 respectively. A bearing 2291 is fixedly sleeved at the end of the transmission handle 229. A limit ring 2292 is fixedly connected to the outside of the bearing 2291. A transmission block 2293 is fixedly connected to one end of the limit ring 2292. The transmission block 2293 is hinged to the first clamping plate 223 and second clamping plate 224 respectively. When the transmission handle 229 is rotated, the bearing 2291 will rotate accordingly, and the limit ring 2292 will not drive the transmission block 2293 to rotate. Hinges 2294 are fixedly installed on the outer sides of the first clamping plate 223 and the second clamping plate 224 respectively. The hinges 2294 are limited to rotate and locked onto one side of the transmission block 2293. The hinges 2294 and the transmission block 2293 are hinged together so that when the transmission handle 229 is rotated, the first clamping plate 223 and the second clamping plate 224 can be brought closer to tighten the zirconia porcelain tooth.
[0034] The clamping assembly 220 includes a mounting block 216, with an extension rod 215 fixedly connected to the bottom of the mounting block 216, and a base 211 connected to the bottom of the extension rod 215. Mounting screw holes are provided on one side of the mounting block 216 and at the four corners of the bottom of the base 211. Screws are threaded into the mounting holes of the mounting block 216, passing through the four corners of the mounting plate 221. The base 211 is mounted on a suitable device or desktop. A mounting cylinder 212 is fixedly connected to the top of the mounting plate 221. The middle of the mounting cylinder 212 is hollow. The extension rod 215 is slidably inserted into the mounting cylinder 212. A threaded cylinder 213 is connected to the top side of the mounting cylinder 212. A knob handle 214 is threadedly connected to the threaded cylinder 213. One end of the knob handle 214 abuts against the outer wall of the extension rod 215. Rotating the knob handle 214 releases and fixes the position of the extension rod 215, facilitating height adjustment.
[0035] Working principle: When grinding the zirconia tooth 100, the tooth is placed in the middle of the first clamping plate 223 and the second clamping plate 224. Then, the transmission handle 229 is rotated. The transmission handle 229 is hinged to the hinge block 2294 on the outside of the first clamping plate 223 and the second clamping plate 224 through the bearing 2291, the limiting ring 2292 and the transmission block 2293 at the end, thereby driving the first clamping plate 223 and the second clamping plate 224 to rotate around the limiting rod 226. Since one end of the first clamping plate 223 and the second clamping plate 224 is connected by a concave and convex joint and passes through the limiting rod 226, they can maintain a relatively stable movement trajectory during rotation, and the tooth pressing plate 225 gradually approaches the tooth, firmly clamping the tooth in the middle position.
[0036] Mounting assembly 210 is used to mount the grinding positioning mechanism 200 in a suitable working position; when adjusting the height, the extension rod 215 slides within the mounting cylinder 212 and is limited in position. When the height is adjusted, the knob handle 214 is rotated, and the knob handle 214 is threaded in the threaded cylinder 213, with its end abutting against the outer wall of the extension rod 215, thereby limiting the position of the extension rod 215.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
