Description

Technical Field

[0001] This utility model relates to the field of oral restoration technology, specifically to a denture simulation frame. Background Technology

[0002] Dentures, commonly known as "false teeth," are prostheses used to replace missing teeth. Their main functions are to restore chewing function, speech function, and facial aesthetics. When teeth are lost or extracted due to cavities, periodontal disease, trauma, or aging, dentures can fill the gaps in the dentition and maintain the integrity of the oral cavity structure. Denture model frames are auxiliary tools used in the denture fabrication process for precise positioning, simulating occlusal relationships, and assisting in processing; they are also called "denture model frames" or "occlusal frames."

[0003] Currently, when simulating dentures, technicians first fix the model on a frame to ensure that the upper and lower teeth are aligned in the centric position (such as the midline being consistent and the cusps and fossae corresponding). However, this is not enough to only satisfy static occlusion, because when patients speak and chew, the mandible frequently makes non-centric movements (such as chewing a steamed bun laterally), which affects the actual use of the denture and is not conducive to helping dental technicians make dentures that better meet the needs of patients. Therefore, we propose a denture simulation frame. Utility Model Content

[0004] The purpose of this invention is to provide a denture simulation frame that is easy to use and helps dental technicians create dentures that better meet the needs of patients. It solves the problem that merely satisfying static occlusion is insufficient, because when patients speak and chew, their mandibles frequently make non-centric movements, which affects the actual use of the denture and is not conducive to helping dental technicians create dentures that better meet the needs of patients.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a denture simulation fixation frame, comprising:

[0006] The base frame has a lower denture opening adjustment plate fixedly connected to the middle of the right side of the base frame, and a support rubber block is fixedly connected to the right end of the bottom of the lower denture opening adjustment plate.

[0007] A guide sleeve, with a spring fixedly connected between the top of the inner side of the guide sleeve and the top of the base frame, a support rod fixedly connected to the upper end of the inner side of the two guide sleeves, a fixing block fixedly connected to the middle end of the outer surface of the support rod, an upper denture opening degree adjustment plate fixedly connected to the upper end of the right side of the fixing block, and an upper denture model fixedly installed at the bottom of the upper denture opening degree adjustment plate.

[0008] A through groove is provided, with a rotating rod movably connected to the inner side of the through groove via a bearing. A guide roller is fixedly connected to the outer surface of the rotating rod located within the through groove. A circulation groove is provided on the outer surface of the guide roller. A movable sleeve is fitted onto the outer surface of the guide roller. A guide slider is fixedly connected to the middle of the top of the inner side of the movable sleeve. A connecting plate is fixedly connected to the top of the movable sleeve. A lower denture model is fixedly installed on the top of the connecting plate.

[0009] Preferably, there are two guide sleeves, which slide on the upper end of the base frame.

[0010] Preferably, the through groove is formed on the inner surface of the lower denture opening adjustment plate.

[0011] Preferably, the guide slider and the circulating rail groove are adapted to each other, and the guide slider slides on the inner side of the circulating rail groove.

[0012] Preferably, a rotating disk is fixedly connected to the front of the rotating rod.

[0013] Preferably, the bottom of the lower denture model is fitted with the top of the lower denture opening adjustment plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention enables the fixed frame to simulate the alignment of the upper and lower denture models in the centric position through simple operation, achieving occlusion. Furthermore, while the front-to-back position of the upper denture model remains unchanged, the lower denture model can move back and forth, thereby achieving non-centric movement and possessing the ability to simulate chewing. This, in turn, helps dental technicians to create dentures that better meet the needs of patients. Attached Figure Description

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] Example 1

[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution: a denture simulation fixation frame, comprising:

[0025] The base frame 1 has a lower denture opening adjustment plate 101 fixedly connected to the middle of the right side of the base frame 1, and a support rubber block 102 fixedly connected to the right end of the bottom of the lower denture opening adjustment plate 101.

[0026] A spring 205 is fixedly connected between the top of the inner side of the guide sleeve 2 and the top of the base frame 1. A support rod 201 is fixedly connected to the upper end of the inner side of the two guide sleeves 2. A fixing block 202 is fixedly connected to the middle end of the outer surface of the support rod 201. An upper denture opening degree adjustment plate 203 is fixedly connected to the upper end of the right side of the fixing block 202. An upper denture model 204 is fixedly installed at the bottom of the upper denture opening degree adjustment plate 203.

[0027] A through groove 3 is provided, and a rotating rod 301 is movably connected to the inner side of the through groove 3 via a bearing. A guide roller 304 is fixedly connected to the outer surface of the rotating rod 301 located in the through groove 3. A circulation track groove 305 is opened on the outer surface of the guide roller 304. A movable sleeve 307 is fitted on the outer surface of the guide roller 304. A guide slider 306 is fixedly connected to the middle of the top of the inner side of the movable sleeve 307. A connecting plate 303 is fixedly connected to the top of the movable sleeve 307. A lower denture model 206 is fixedly installed on the top of the connecting plate 303.

[0028] There are two guide sleeves 2, which slide on the upper end of the base frame 1. The through groove 3 is opened on the inner surface of the lower denture opening adjustment plate 101. The guide slider 306 and the circulation rail groove 305 are matched, and the guide slider 306 slides on the inner side of the circulation rail groove 305. The bottom of the lower denture model 206 is in contact with the top of the lower denture opening adjustment plate 101.

[0029] This technical solution involves fixing the upper denture model 204 and the lower denture model 206 to the bottom of the upper denture opening adjustment plate 203 and the top of the connecting plate 303 respectively using screws. The lower denture model 206, fixedly connected to the connecting plate 303, fits against the top of the lower denture opening adjustment plate 101. After the bottom of the base frame 1 and the supporting rubber block 102 contacts the supporting surface, the stability of the support frame during use is ensured. Then, the upper denture opening adjustment plate 204... The cooperation of the fixing block 202 and the support rod 201 causes the guide sleeve 2 to slide downward on the upper end of the outer surface of the base frame 1, which compresses the spring 205 and allows the upper denture model 204 to move closer to the lower denture model 206. This simulates the alignment of the upper denture model 204 and the lower denture model 206 in the center position, achieving engagement. At this time, the guide roller 304 is rotated by the rotating rod 301 (and the lower denture model 206 and the lower denture opening adjustment plate 10...). With the assistance of the top fitting, the stability of the connecting plate 303 and the movable sleeve 307 is ensured. This forces the guide slider 306 to slide inside the circulating rail groove 305. As the guide slider 306 moves, it drives the movable sleeve 307 to move back and forth outside the guide roller 304. This allows the movable sleeve 307 to drive the lower denture model 206 to move synchronously via the connecting plate 303 (the movement causes the lower denture model 206 to slide back and forth on the top of the lower denture opening adjustment plate 101). With the front and back positions of the upper denture model 204 unchanged, the back and forth movement of the lower denture model 206 can achieve non-centric movement and has the ability to simulate chewing. After use, the upper denture opening adjustment plate 203 is released, and the compressed spring 205 will drive the guide sleeve 2 to return to its original position. Finally, the upper denture model 204 and the lower denture model 206 can be removed. It is easy to use and can help dental technicians make dentures that better meet the needs of patients.

[0030] It should be noted that the lower denture opening adjustment plate 101, upper denture opening adjustment plate 203, upper denture model 204 and lower denture model 206 used in this fixation frame can all be purchased directly from the market or made. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0031] Example 2

[0032] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a rotating disk 302 is fixedly connected to the front of the rotating rod 301.

[0033] This technical solution: By setting up the rotating disk 302, it is convenient for the user to operate the rotating rod 301.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
