Description

Technical Field

[0001] The present invention relates to the technical field of denture processing, and in particular to a denture curved surface processing device and a processing method. Background Art

[0002] Dentures are often referred to as false teeth, much like artificial legs and limbs are called prosthetic limbs. Dentures refer to teeth that fulfill a human duty. In medicine, they are a general term for restorations made after partial or complete tooth loss in the upper or lower jaws. Dentures are categorized as removable and fixed. Fixed dentures cannot be removed by the patient, while removable dentures can be easily removed. Fixed dentures use healthy teeth on either side of the missing teeth as support to secure the dentures in place. They are suitable for patients with minimal or intermittent tooth loss and good remaining teeth. Their advantages are high chewing efficiency, comfort, minimal foreign body sensation, and the need to remove them. However, their disadvantages are that they require partial removal of healthy teeth on either side of the missing teeth before full crown restorations are performed. Removable dentures are self-removable and are suitable for patients with major tooth loss and few remaining teeth. Their advantages are that they can be removed for cleaning, which reduces the burden on the remaining teeth. However, they also come with the inconvenience of lower chewing efficiency and the need to remove and clean them after meals. Dental implants, a relatively new technology that has seen rapid development in recent years, involve placing an implant within the alveolar bone. Once the implant and alveolar bone have formed an osseointegration, a replacement tooth is placed over the implant. However, implants require good overall health and a certain alveolar bone height and width. While implants are comfortable and aesthetically pleasing, and do not damage adjacent teeth, they are relatively expensive.

[0003] Taking into account the above reasons, fixed dentures are still the choice of most patients. However, the existing fixed dentures have the following problems during processing:

[0004] During the denture processing process, it is difficult to tailor the denture's curved surface to the patient's specific needs. This results in the doctor needing to perform a secondary polishing process before the denture is installed to meet the needs of the patient. However, traditional denture processing equipment is large and difficult to meet the processing needs of doctors and others. Furthermore, due to the limitations of denture processing materials, manual polishing takes a relatively long time and is also difficult to control the dimensions.

[0005] In order to solve the above problems, reduce the difficulty of secondary polishing of dentures and improve the polishing efficiency, it is necessary to develop a small device and method suitable for processing the curved surface of dentures. Summary of the Invention

[0051] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0053] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0054] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] The denture curved surface processing device provided by the present invention includes a mounting shell, a grinding component, a fixing component and a rotating component. Figure 1 The mounting housing is a hollow structure with a mounting hole at its upper end for mounting the polishing assembly. The polishing assembly is mounted on the mounting housing through the mounting hole. The fixing assembly is located outside the mounting hole and can move toward or away from the mounting hole along a fixed path. The denture to be polished is fixed to the fixing assembly. The rotating assembly is connected to the fixing assembly and can adjust the angle of the denture to be polished.

[0056] With the coordination of these multiple components, the denture curved surface machining device can conveniently adjust the position of the denture to be polished so that its surface can fully contact the polishing components, thereby achieving multi-angle and multi-faceted polishing of the denture. Simultaneously, the rotation of the denture can achieve the effect of machining a curved surface on the denture surface. The use of this device can effectively reduce the difficulty of denture polishing and improve polishing accuracy and efficiency.

[0057] Specifically, in this embodiment, an operating table is fixedly provided on the upper end of the installation shell, and the installation hole is formed in the middle of the operating table.

[0058] The structure of the above-mentioned grinding assembly is described in detail below:

[0059] like Figure 2 As shown, the grinding assembly includes a grinding component and an angle adjustment component, wherein the grinding component is fixedly mounted at the mounting hole via the angle adjustment component, and the grinding component can rotate relative to the mounting hole under the action of the angle adjustment component to adjust the mounting angle of the grinding component.

[0060] The angle adjustment member is used to adjust the angle of the grinding member, thereby making the grinding angle of the device adjustable to meet higher grinding requirements. In addition, in order to facilitate the rotation of the grinding member, it is necessary to set the size of the above-mentioned mounting hole to be larger than the size of the grinding member. At the same time, the debris and powder generated during grinding can fall into the mounting housing through the mounting hole.

[0061] Specifically, the polishing assembly includes a drive unit, a fixed frame, and an abrasive cloth. A positioning roller, which assists in rotation, is connected to the inner wall of the fixed frame via a rotating shaft. The abrasive cloth is wound around the fixed frame via the positioning roller. The drive unit is connected to the positioning roller and drives the abrasive cloth to rotate relative to the fixed frame. The drive unit is a motor. Driven by the motor, the positioning roller rotates, driving the abrasive cloth to rotate, thereby polishing the denture surface.

[0062] Using abrasive cloth to polish dentures allows the operator to more accurately control the polishing size and is also safer to use. The selection and replacement of the abrasive cloth can be done according to actual needs. When the abrasive cloth is worn or its surface roughness does not meet the polishing requirements, it can be replaced.

[0063] In this embodiment and similar embodiments, the driving member is connected to a side key of the positioning roller.

[0064] Specifically, the angle adjustment component includes a mounting seat, a limiting ring and a fixing rod. There are two mounting seats, which are located on both sides of the mounting hole. The fixing rod is passed through the mounting seat and is installed on the fixing frame. One end of the fixing rod passing through the fixing frame is threadedly connected to the limiting ring for limiting.

[0065] The grinding angle of the grinding component can be adjusted through the angle adjustment component, so as to facilitate grinding to form different curved surface curvatures.

[0066] It is important to note that the mounting seats need to be located on opposite sides of the mounting hole, perpendicular to the movement path of the fixing assembly. In addition, to further improve the stability of the polishing member and prevent it from deflecting or shaking relative to the fixing assembly, an anti-slip washer is also provided on the fixing rod.

[0067] As an optional embodiment, the driving member is located in the mounting housing. By having the driving member built in, the operating noise of the device can be reduced, while protecting the driving member and preventing damage to the driving member.

[0068] The structure of the above-mentioned fixing components is described below:

[0069] In this embodiment and similar embodiments, the fixing assembly includes a mounting frame and a limit adjustment plate, wherein the mounting frame is a strip-shaped structure, and a strip groove is provided in the middle of its upper surface, and the limit adjustment plate can be fixedly installed on the mounting frame through the strip groove; the number of limit adjustment plates is two and they are symmetrically arranged, and any limit adjustment plate includes a limit plate and a pressure rod, and a threaded hole is provided on the limit plate. The pressure rod is connected to the limit plate through the threaded hole and adjusts the position of the limit plate on the mounting frame.

[0070] The fixed position of the denture to be polished can be adjusted laterally by the limit adjustment plate to meet the polishing requirements of dentures of different sizes.

[0071] Specifically, the shapes of the above-mentioned limiting plate and the strip groove match each other, such as Figure 4 As shown, the limit plate can slide along the strip groove. When the limit plate moves to a suitable position, it can be fixed by the above-mentioned pressure rod.

[0072] It should be noted that in this embodiment and similar embodiments, the above-mentioned limit plate can be set as an integrated structure, or the limit plate can be set to include a guide block and an L-shaped plate, wherein the lower end of the guide block can cooperate with the strip groove, one end of the L-shaped plate is fixedly connected to the guide block, and the other end can extend downward along the side wall of the mounting frame, and the above-mentioned threaded hole is formed on the L-shaped plate.

[0073] In order to adjust the distance between the fixed component and the grinding component and to move the fixed component along a fixed path, as an optional embodiment, a slider is fixedly provided at the lower end of the mounting frame, and a slide groove is provided on the upper surface of the mounting shell, such as Figure 3 One end of the slide is connected to the mounting hole, and the other end is extended toward a side away from the mounting hole; the slider is connected to the slide and can slide along the slide.

[0074] The above-mentioned slider and slide groove cooperate with each other to enable the fixing component to move relative to the mounting hole or the grinding component.

[0075] In this embodiment, the middle parts of the left and right side walls of the slider are relatively convex, and the corresponding positions of the slide groove are relatively concave. The above-mentioned convexity and concave cooperate with each other to fix the slider on the slide groove to prevent the slider from falling out of the slide groove during movement.

[0076] In order to facilitate the operator to push the above-mentioned fixing assembly, as an optional implementation, the fixing assembly further includes a force applying member, the number of which is two and which are respectively fixedly arranged on both sides of the mounting frame.

[0077] At this time, the operator can push the fixing component to move by holding the force applying member.

[0078] In this embodiment, a non-slip area is provided on a surface of the force applying member facing away from the polishing assembly.

[0079] In order to further enhance the fixing firmness of the fixing assembly on the denture to be polished, the fixing assembly also includes a compression spring, one end of the compression spring is connected to the force-applying member or the side wall of the mounting frame (at this time, the length of the above-mentioned strip groove is less than the length of the mounting frame and there is a certain distance between the two ends of the strip groove and the two ends of the mounting frame), and the other end abuts against the outer surface of the limit plate.

[0080] The above-mentioned force-applying member can help the operator push the fixing component closer to or away from the grinding component, and the compression spring can apply a certain pressure to the limit plate, thereby improving the fixing firmness between the limit plate and the denture to be ground, and preventing the denture to be ground from falling off the fixing component.

[0081] To improve the connection strength of the compression spring, the two ends of the compression spring can be fixedly connected to the two side walls they abut; alternatively, corresponding positions of the two side walls abutting the spring can be formed with limiting posts that can be inserted into the compression spring. It is only necessary to ensure that the provision of the limiting posts does not affect the normal use of the compression spring. The above structures are all existing technologies and will not be described in detail here.

[0082] The structure of the above-mentioned rotating assembly is described below:

[0083] In this embodiment and similar embodiments, the rotating component includes a positioning plate fixedly connected to the mounting frame, the positioning plate is located between the slider and the mounting frame and is rotationally connected to the slider through a rotating shaft; and / or, the rotating component includes two splints, the number of which is two and the two splints are rotationally connected to the limit plate through a rotating shaft, and the denture to be polished is held by the two splints arranged opposite to each other.

[0084] The above structure can adjust the horizontal and vertical angles of the denture to be polished respectively, thereby making it more convenient for the staff to perform the polishing operation.

[0085] It should be noted that the shape of the positioning plate is not limited. Furthermore, to facilitate the rotation of the splint, a raised handle is provided on the side of the splint closest to the operator. To prevent the splint from damaging the denture surface, a non-slip rubber pad is provided at the contact surface between the splint and the denture. This pad provides cushioning and anti-slip properties, effectively protecting the denture and preventing damage.

[0086] The structures of the above-mentioned fixed component and rotating component are as follows: Figure 4 shown.

[0087] To ensure that the design of the rotating assembly does not affect the normal fixation of the denture, in this embodiment and similar embodiments, the positioning plate and the slider are connected by a rotating shaft, and the connection relationship of the rotating shaft is a transition fit. This ensures that the positioning plate can and only can rotate when pushed by an external force (i.e., it will not rotate arbitrarily), thereby ensuring that its rotation angle is controlled. Similarly, after the denture is installed in the corresponding position, there is a large extrusion and friction force between the limit plate and the clamping plate. Under the action of these forces, the clamping plate will not rotate arbitrarily relative to the limit plate. It will only rotate when the operator pushes it hard. Therefore, the problem of uncontrolled rotation angle will not occur, thereby effectively ensuring the accuracy of the grinding angle.

[0088] At this time, the denture to be polished can be moved closer to or away from the polishing component under the fixation of the fixing component, so as to adjust the distance between the denture to be polished and the polishing component according to the actual situation, making it convenient for the polishing personnel to adjust the polishing angle and observe the polishing degree; at the same time, the effect of polishing and rotating at the same time can also be achieved under the action of the rotating component, thereby realizing the curved surface processing of the denture surface.

[0089] To further enhance the device's ease of use, a controller electrically connected to the grinding assembly is optionally mounted on the outer surface of the mounting housing. This controller allows the operator to control the drive element within the grinding assembly, for example, by starting and stopping the drive element and adjusting its speed.

[0090] The structure and connection method of the controller are prior art and will not be described in detail here.

[0091] Alternatively, in order to facilitate the temporary placement of dentures that have been polished or are to be polished, an anti-slip pad can be provided on the operating table. The anti-slip pad is located on one side of the mounting hole and is made of rubber material.

[0092] To prevent polishing debris and dust from contaminating the equipment and the environment, a collection box is installed on the mounting housing. This box is located below the mounting hole, allowing the polishing dust to fall through the mounting hole into the collection box. The collection box is a drawer-shaped structure with a handle for pushing and pulling on the outside, and the handle is covered with a protective cover.

[0093] At least part of the sidewall of the installation housing is provided with a light-transmitting plate for transmitting light, through which an operator can observe the interior of the installation housing. When the light-transmitting plate is arranged near the collection box, the operator can obtain the dust collection status in the collection box in a timely manner through the light-transmitting plate.

[0094] In order to facilitate the movement of the device, a universal wheel can be fixedly installed on the bottom of the installation shell, and the number of the universal wheels is four and they are respectively located near the four corners of the bottom surface of the installation shell. A brake structure is provided outside the universal wheel.

[0095] The structure of the above-mentioned mounting housing is as follows Figure 5 shown.

[0096] The present invention also provides a denture curved surface processing method, which is implemented by the denture curved surface processing device as described in any one of the above, comprising the following steps:

[0097] S1: Fix the denture to be polished by fixing components;

[0098] S2: Adjust the grinding angle and grinding speed of the grinding component, and adjust the angle of the denture to be ground by rotating the component so that the area to be ground faces the grinding component;

[0099] S3: Start the grinding component and adjust the distance between the denture to be ground and the grinding component through the fixing component.

[0100] The method further comprises, after the grinding is completed, closing the grinding assembly and removing the denture fixed on the fixing assembly.

[0101] The specific steps are as follows:

[0102] First, place the denture to be processed on the anti-slip mat, loosen the pressure rod, and adjust the distance between the two limit plates. Once adjusted, the denture can be clamped on the clamping plate between the two limit plates using the elastic force of the compression spring. Then, tighten the pressure rod again to secure the limit plates. The position of the mounting frame can then be adjusted using the slide and slider.

[0103] Secondly, loosen the limit ring and adjust the angle of the fixing bracket so that the sanding cloth reaches the angle suitable for sanding, then tighten the limit ring again to fix the angle of the fixing bracket; then start the motor and adjust the motor speed through the controller.

[0104] Finally, push the fixing assembly to move the denture toward the abrasive cloth to polish the denture surface. At this point, the mounting frame and / or splint can also be rotated to change the angle of the denture horizontally or vertically to achieve curved surface polishing.

[0105] After grinding is complete, the drive unit must be switched off and the denture removed, followed by cleaning of the equipment.

[0106] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
