Abstract

The present invention relates to the field of dental mold processing technology, and more specifically, to a dental mold overall positioning and cutting device and a dust collection component. It includes a positioning and cutting component and a dust collection component. In the present invention, a person holds the second knob by hand to drive the center plate to move left and right and front and back. When the disk saw approaches the whole dental mold, the person holds the second knob to drive the center plate to rotate with the fixed arm as the axis, so that the disk saw can change its angle and enter the gap for cutting, thereby removing the required tooth model from the whole dental mold. When the disk saw rotates and cuts, it drives the synchronous sleeve to rotate synchronously, and then drives the fan blades to rotate, so that the fan blades continuously drive the air flow, forming an airflow passing through the air duct from top to bottom. The tooth powder produced by the disk saw cutting flies out along the rotating cutting direction of the disk saw, and can be captured by this airflow and entrained to fall into the collection tank for collection, thereby avoiding health problems caused by long-term inhalation of tooth powder.

Description

Technical Field

[0001] The invention relates to the technical field of dental mold processing, in particular to a dental mold integral positioning and cutting device and a dust collecting component. Background Art

[0002] A dental cast is a model used by doctors to analyze tooth shaping plans. It is usually made by mixing tooth powder and water. The general steps for making a dental cast include preparation in the dental clinic or laboratory, oral cleaning, applying impression materials, maintaining occlusion, making the mold, and curing the mold.

[0003] For example, the patent with announcement number CN219926160U involves a dental mold fixing seat and cutting equipment for braces cutting. The dental mold fixing seat for braces cutting can be matched with the dental mold positioning part through the dental mold positioning part arranged on the fixing seat body. By setting at least three groups of buckle parts whose buckle positions are not distributed along the same straight line, not only can they be buckled and connected with the dental mold respectively, but also they will not be affected by the special-shaped structure of the dental mold periphery, and a fixing structure with at least one triangular fixing position can be formed, and the stability of clamping the dental mold is better; therefore, the dental mold fixing seat for braces cutting can be used to fix the dental mold. The mold fixing seat is used to clamp and fix the dental membrane during the braces cutting process. It not only has good clamping stability but also high positioning accuracy, which is conducive to ensuring the accuracy of braces cutting. However, the dental mold fixing seat and the cutting equipment lack corresponding dust treatment structure. The dental mold is made of tooth powder, and the main material of tooth powder is gypsum powder. When the cutting equipment cuts the dental mold, a large amount of flying gypsum powder will be generated.

[0020] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the process of oral restoration and dental implantation, generating a model that perfectly matches the missing teeth is a critical step. Compared with the prior art, the tooth model generation system and method based on gap positioning matching provided by the present invention not only considers the characteristics of the teeth around the gap, but also analyzes the shape and occlusal characteristics of the opposing teeth, thereby ensuring that the upper and lower teeth have a precise match when biting, regardless of whether the gap is located in the upper teeth or the lower teeth.

[0022] Through the characteristic analysis of upper and lower teeth, the present invention can automatically generate a three-dimensional tooth model corresponding to the gap, reducing human intervention, improving the accuracy and efficiency of model generation, and paying attention to the processing of the model edge to ensure the natural connection between the generated gap tooth model and the surrounding teeth and alveolar bone, which not only ensures the restoration of tooth function, but also improves the aesthetic effect.

[0023] The problem is that after the present invention prepares the dental mold according to the generated three-dimensional dental model, the notched tooth model needs to be cut off from the dental mold as a whole. The existing dental mold cutting device includes a model knife or a dental wax knife. Among them, the model knife has the disadvantages of requiring certain skills and experience and easily scratching or injuring the hands, and the dental wax knife needs to be proficient in controlling the temperature when using it. Both have certain requirements for personnel, and both will generate dust when cutting the dental mold, which will affect the health of personnel.

[0024] Therefore, please refer to Figure 1 , Figure 2 , Figure 6 As shown, the purpose of this embodiment is to provide a dental mold integral positioning and cutting device and a dust collection component, including a positioning and cutting component 1 and a dust collection component 2 arranged on the positioning and cutting component 1.

[0025] The positioning and cutting assembly 1 includes a model positioning body 11 and a tooth cutting body 12 arranged on the model positioning body 11. The model positioning body 11 is used to position and fix the dental mold. The tooth cutting body 12 moves on the model positioning body 11 to change the relative angle between the tooth cutting body 12 and the dental mold and cut the dental mold.

[0026] The dust collecting assembly 2 includes a tooth powder cleaning body 21 arranged on the tooth cutting body 12 and a tooth powder collecting body 22 connected to the tooth powder cleaning body 21. When the tooth cutting body 12 cuts, it drives the tooth powder cleaning body 21 to rotate synchronously to clean the tooth powder attached to the dental mold. The tooth powder collecting body 22 is used to collect the tooth powder. First, the entire dental mold is positioned and fixed by the model positioning body 11, and then the tooth cutting body 12 is moved on the model positioning body 11. After adjusting the angle of the tooth cutting body 12 relative to the dental mold, the dental mold is cut to remove the required tooth part. When cutting, the tooth cutting body 12 will drive the tooth powder cleaning body 21 to rotate synchronously to clean the tooth powder attached to the dental mold, and the tooth powder cleaning body 21 drives the tooth powder collecting body 22 to generate an airflow passing through the tooth powder collecting body 22, and the airflow is used to entrain the tooth powder so that the tooth powder falls into the tooth powder collecting body 22 and is collected, thereby avoiding health problems caused by long-term inhalation of tooth powder.

[0027] The above structure is disclosed as follows: like Figure 3As shown, the model positioning body 11 includes a processing table 111 for maintaining stability and a fixed arm 112 arranged at one end of the top of the processing table 111, one end of the fixed arm 112 is connected to an upper and lower opposed frame 113 with a "Y"-shaped structure. When performing a cutting operation, it is necessary to ensure the stability of the entire dental model. The upper and lower opposed frames 113 are provided with a rotatably connected movable arm 114 at one end away from the fixed arm 112, and one end of the movable arm 114 is rotatably connected to a first knob 115, and the first knob 115 is threadedly connected to a clamping frame 116 for contacting the dental model. By rotating the movable arm 114 at one end of the upper and lower opposed frames 113, the movable arm 114 drives the clamping frame 116 to approach the entire dental model to be cut. After the two sides of the tooth part are reached, by rotating the first knob 115 threadedly connected to the clamping frame 116, the clamping frame 116 located above and below the dental model as a whole is close to the dental model and clamps the dental model up and down. Considering that the dental model is not a regular object, the effective contact area of ​​the clamping frame 116 when clamping the dental model is limited, which will cause excessive pressure at the contact part when the dental model is clamped, and the dental model will be damaged and deformed. Therefore, a rubber gasket is provided on the contact surface between the clamping frame 116 and the dental model. When the clamping frame 116 clamps and fixes the dental model, the gap between the dental model and the clamping frame 116 is filled by deformation of the gasket, thereby increasing the effective area of ​​the clamping frame 116 when clamping the dental model to avoid damage and deformation of the dental model.

[0028] After the positioning and fixing of the dental model as a whole is completed, the relative angle between the tooth cutting body 12 and the dental model as a whole needs to be adjusted so that the tooth cutting body 12 can cut and remove the required tooth model from the dental model as a whole. Figure 4 , Figure 5As shown, the tooth cutting body 12 includes a first connecting arm 121 and a cutting structure 123. The first connecting arm 121 is a "C"-shaped structure. The middle part of the first connecting arm 121 is sleeved on one end of the fixed arm 112 and is rotatably connected to the fixed arm 112. The two ends of the first connecting arm 121 are plugged with the second connecting arm 122. The cutting structure 123 includes a central plate 1231 and extension arms 1232 symmetrically arranged on both sides of the central plate 1231. The extension arms 1232 pass through the second connecting arm 122 away from the fixed arm 112. At one end of the first connecting arm 121, the middle plate 1231 is plugged and matched with one end of the second connecting arm 122 through the extension arms 1232 arranged on both sides, so that the middle plate 1231 can move left and right, and a miniature table saw motor 1233 is arranged at the bottom of the middle plate 1231, and a disk saw 1234 is arranged at one end of the middle plate 1231 close to the dental mold. The miniature table saw motor 1233 is connected to the shaft of the disk saw 1234 through a first gear set, and a second knob 1234 is arranged at one end of the middle plate 1231 away from the dental mold. 235, the first gear group includes a first gear rod and a second gear rod arranged in the middle plate 1231, the output shaft of the miniature table saw motor 1233 is meshed with one end of the first gear rod, the other end of the first gear rod is meshed with one end of the second gear rod, and the other end of the second gear rod is meshed with the shaft of the disk saw 1234. After the dental model is fixed as a whole, the personnel hold the second knob 1235 by hand, and drive the middle plate 1231 to rotate according to the position of the tooth model to be cut in the dental model as a whole through the second knob 1235. The disk saw 1234 is moved left and right, and then drives the second connecting arm 122 to extend and retract at both ends of the first connecting arm 121, so as to realize the forward and backward displacement of the center plate 1231. When the disk saw 1234 is close to the entire dental model, the second knob 1235 is held to drive the center plate 1231 to rotate with the fixed arm 112 as the axis, so that the disk saw 1234 can change its angle and enter the gap between the tooth model to be removed and the adjacent tooth model on the entire dental model, and cut from the gap to remove the required tooth model from the entire dental model.

[0029] It is worth noting that the disk saw 1234 will produce flying tooth powder when cutting the whole dental model. If personnel inhale excessive gypsum powder during dental model processing, it will affect the respiratory system and cause symptoms such as coughing and asthma, which will not only affect the quality of dental model processing, but also cause health problems for personnel. In order to avoid this situation, the tooth powder needs to be collected and processed during cutting, such as Figure 6 , Figure 7 , Figure 8As shown, the tooth powder cleaning body 21 includes a synchronous sleeve 211 arranged in pairs, and the two synchronous sleeves 211 are sleeved on the shafts at both ends of the disk saw 1234. The synchronous sleeve 211 rotates synchronously with the shaft of the disk saw 1234. A plurality of support plates 212 are arranged on the periphery of the synchronous sleeve 211, and a soft brush 213 for brushing off the attached tooth powder is arranged on the support plate 212. Among the tooth powder produced by the cutting of the disk saw 1234, part of it will be attached to the tooth model, and it is necessary to brush off this part of the attached tooth powder to avoid the problem of damage to the tooth model cutting caused by the personnel's misjudgment of the contour of the tooth model. Through the tooth powder cleaning body 21 that is arranged, when the disk saw 1234 rotates to cut the tooth model, it can drive the synchronous sleeve 211 to rotate synchronously, and then the soft brush 213 arranged on the support plate 212 will contact the tooth powder attached to the surface of the tooth model and brush it off. Considering the disk The cutting position of the saw 1234 is located in the gap between the tooth model to be removed and the adjacent tooth model, and the surface of the tooth model is curved. Therefore, in order to better brush off the attached tooth powder, the soft brush 213 is tilted on the support plate 212 toward the disk saw 1234, and the length of the soft brush 213 matches the curvature of the surface of the tooth model. The purpose of the tilted setting is to facilitate the movement of the soft brush 213 in the tooth gap, and by matching the length of the soft brush 213 with the curvature of the surface of the tooth model, when the synchronous sleeve 211 drives the soft brush 213 to rotate, the end of the soft brush 213 can scrape off the tooth powder attached to the surface of the tooth model. If the length of the soft brush 213 is too short, it will not be able to contact the surface of the tooth model. If the length of the soft brush 213 is too long, it will cause the soft brush 213 to bend on the surface of the tooth model, thereby affecting the brushing effect of the tooth powder.

[0030] In addition, a plurality of movable grooves 2111 are provided on the periphery of the synchronous sleeve 211, and the end of the support plate 212 away from the soft brush 213 is located in the movable groove 2111 and is rotatably connected to the inner wall of the movable groove 2111. A spring is provided on the side wall of the support plate 212, and the support plate 212 is connected to the inner wall of the movable groove 2111 through the provided spring. The disk saw 1234 will penetrate into the tooth gap when cutting the dental model. By providing a rotating connection and a spring connection, when the disk saw 1234 penetrates into the tooth gap for cutting, the soft brush 213 in contact with the surface of the dental model will drive the support plate 212 to rotate in the movable groove 2111 to overcome the spring elastic force, thereby avoiding the problem that the disk saw 1234 cannot penetrate into the deep tooth gap for cutting due to the support plate 212 being stuck on the surface of the dental model.

[0031] The tooth powder attached to the surface of the tooth model is brushed off by the tooth powder cleaning body 21 and moves downward along the rotating cutting direction of the disk saw 1234 together with the remaining tooth powder produced by the disk saw 1234, falls into the tooth powder collecting body 22 and is collected by the tooth powder collecting body 22.

[0032] The structure of the tooth powder collecting body 22 is disclosed in detail below: like Figure 8 , Fig. 9 , Fig.10 As shown, the tooth powder collector 22 includes a collection box 221 for collecting tooth powder and a suspension arm 222 arranged at the top of the collection box 221. A first reel 214 is provided on the side wall of the synchronous sleeve 211 away from the disk saw 1234. The first reel 214 passes through the top of the suspension arm 222. A contact roller 225 for contacting the dental mold is provided on the outer wall of the suspension arm 222 close to the dental mold. The collection box 221 is hung on the first reel 214 through the top suspension arm 222. The collection box 221 is located below the disk saw 1234 as a whole due to its own gravity, and the collection box 221 contacts the dental mold through the contact roller 225, so that the collection box 221 is inclined. Fig.11 As shown in the figure, the dotted object represents the dental mold. When the disk saw 1234 rotates and cuts the dental mold in the direction indicated by arrow a, the generated tooth powder will fly out along the rotating cutting direction of the disk saw 1234, as shown by arrow b. By tilting the collection box 221, the flying tooth powder can just enter the collection box 221 and be collected.

[0033] Considering that some tooth powder will be caught by the airflow formed by the rotating cutting of the disk saw 1234 when flying out and thus cannot fall into the collection box 221, a collection groove 2211 for accommodating tooth powder is provided in the collection box 221, and an air duct 2212 penetrating the bottom surface of the collection box 221 is provided at the bottom of the collection groove 2211, and a fan blade 223 is provided in the middle of the air duct 2212, and second reels 2213 meshing with the fan blade 223 are provided at both ends of the air duct 2212, and the second reel 2213 is connected to the first reel 214 through a belt drive, and a filter cover 224 for intercepting tooth powder is provided on the top of the air duct 2212, and the disk saw 1234 drives the synchronous sleeve 211 to rotate synchronously when cutting, and the synchronous sleeve 211 further drives the fan blade 223 to rotate through the second reel 2213 driven by the first reel 214, so that The fan blades 223 continuously drive the air flow, forming an airflow passing through the air duct 2212 from top to bottom. The tooth powder produced by the cutting of the disk saw 1234 flies out along the rotating cutting direction of the disk saw 1234, is captured by the airflow and carried into the collection groove 2211, is intercepted by the filter cover 224, and is collected in the collection groove 2211. Furthermore, in order to prevent the tooth powder from accumulating on the filter cover 224 and causing blockage, thereby affecting the adsorption and collection effect of the tooth powder, the collection groove 2211 is a "W"-shaped groove, and the air duct 2212 is located at the raised part in the middle of the collection groove 2211. After the tooth powder is intercepted by the filter cover 224, it slides along the surface of the collection groove 2211 to a lower position, namely, the grooves at both ends of the collection groove 2211, so that the tooth powder will not be inhaled by people, thereby avoiding health problems caused by long-term inhalation of tooth powder.
