Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, specifically to a nighttime anti-abrasion dental prosthesis buffer layer structure. Background Technology

[0002] Dentures are a common restorative method in the field of oral prosthetics. They are usually used to replace missing teeth and restore the patient's chewing and aesthetic functions. Existing dentures are divided into two types: removable and fixed. Fixed dentures cannot be removed or worn by the patient, while removable dentures can be easily removed and worn by the patient. Removable dentures are further divided into partial removable dentures and complete removable dentures.

[0003] Removable dentures require periodic disassembly for maintenance and reinstallation. However, existing technologies make the installation and disassembly process inconvenient, increasing the workload of maintenance personnel. To overcome these shortcomings, existing technology (Chinese patent application number 202421333606.2, application date 2024-06-12) describes an easily detachable denture structure. This structure involves inserting a mounting post between multiple pressure plates, pressing down and rotating the post. As the post and pressure plates rotate and enter the mounting groove, the pressure plates are compressed by the post and contract outwards, firmly fixing the denture body. The process of disassembling and installing the denture body is simple, reducing the workload of maintenance personnel. However, existing dentures can cause relative grinding between dentures or between dentures and normal teeth when worn by users who grind their teeth at night. This grinding can damage the dentures or normal teeth, and may also cause the removable denture to shift position, affecting its normal use.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a nighttime anti-abrasion denture buffer layer structure that can effectively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a nighttime anti-brushing denture buffer layer structure to solve the problem mentioned in the background art, which is that when wearers grind their teeth at night, relative grinding occurs between dentures or between dentures and normal teeth, which can damage the dentures themselves or normal teeth. Furthermore, the grinding may cause the removable dentures to shift in position, thus affecting normal use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nighttime anti-abrasion denture buffer layer structure, comprising a denture body, with a gingival veneer fixedly connected to the bottom end of the denture body; four evenly distributed grooves are provided at the top end of the denture body, and anti-abrasion blocks are slidably connected to the inner side of the grooves, and an ejection mechanism is provided at the bottom end of the anti-abrasion blocks, the ejection mechanism including a pressure sensor fitted and installed at the bottom end of the anti-abrasion blocks; a receiving groove communicating with the four grooves is provided at the top end of the inner part of the denture body; an ejection rod is fixedly connected to the bottom end of the anti-abrasion blocks, and the ejection rod penetrates into the inner side of the receiving groove and contacts its bottom end; a motor is fixedly installed at the center of the bottom end of the receiving groove, and a connecting shaft is fixedly connected to the top output shaft of the motor; a rotating rod and a pushing block are sequentially fixedly connected to the outer wall of the connecting shaft, and the pushing block is located on the circular trajectory formed by the four anti-abrasion blocks.

[0007] Preferably, the bottom end of the ejector rod is formed with a rounded edge, and the push block is formed with a gently sloping isosceles trapezoidal structure.

[0008] Preferably, the bottom end of the receiving groove is fixedly connected to a limiting arc plate on the outside of the four ejector rods, and a fixing rod is fixedly connected between the inner side of the limiting arc plate and the receiving groove. A sliding plate is fixedly connected to the outer wall of the ejector rod, and the sliding plate slides on the inner side of the limiting arc plate and the outer side of the fixing rod.

[0009] Preferably, a pull-back spring is fixedly connected between the slide plate and the bottom end of the receiving groove, and the pull-back spring is located outside the fixed rod to ensure the stability of the ejector rod and anti-wear block stored in the receiving groove and slide during daily use.

[0010] Preferably, an electrical stimulation head is fitted inside the top of the anti-wear block, and the electrical stimulation head is electrically connected to the pressure sensor.

[0011] Preferably, a sealing plate is fixedly connected to the bottom end of the receiving groove on the outside of the connecting shaft for sealing and protecting the motor.

[0012] Preferably, a protective pad is fixedly bonded to the inner top of the gingival patch, and a plurality of evenly distributed buffer springs are fixedly connected between the protective pad and the denture body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This nighttime anti-abrasion denture buffer layer structure, through the coordinated use of the sliding groove, anti-abrasion block, and ejection mechanism, when the pressure sensor detects that the pressure on the surface of the denture body exceeds the set value, the motor starts to drive the connecting shaft, rotating rod, and pushing block to rotate synchronously. The pushing block then pushes the ejection rod and anti-abrasion block upwards to lift and separate the teeth or denture body that are grinding against the denture body, thereby avoiding tooth damage caused by grinding and displacement of the denture body, ensuring normal use. The specific contents are as follows: (1) By using the sliding groove, anti-wear block and ejection mechanism in combination, the pressure sensor is used to monitor the surface pressure of the denture body in real time. When the pressure sensor detects that the pressure exceeds the set value, the motor starts to drive the connecting shaft, rotating rod and pushing block to rotate synchronously. During the movement, the pushing block will push the ejection rod and anti-wear block upward, so that the teeth or dentures that are being ground by the denture body are lifted up and separated, thereby avoiding tooth damage caused by grinding and displacement of the denture body, and ensuring normal use.

[0014] (2) By limiting the sliding of the limiting arc plate, the sliding plate and the fixed rod, the movement of the ejector rod can be stably limited in the vertical direction, thereby ensuring the vertical stability of the anti-wear block being pushed upward. In addition, by setting a pull-back spring, the ejector rod can be pulled back to its original position in time, and the stability of the ejector rod and anti-wear block stored in the receiving groove and slide groove during daily use can be guaranteed.

[0015] (3) By fitting an electric stimulation head into the top of the anti-wear block and electrically connecting the electric stimulation head to the pressure sensor, when the pressure sensor detects that the pressure exceeds the standard, the electric stimulation head can be controlled to release a small current to stimulate the teeth that are in contact with the denture body to spring away, so as to assist the anti-wear block and the ejection mechanism to achieve a better anti-wear effect.

[0016] (4) The combination of the protective pad between the gingival veneer and the denture body and multiple buffer springs can provide further buffer protection for the gums during tooth grinding. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a nighttime anti-grinding denture buffer layer structure, including a denture body 1, and a gingival veneer 2 fixedly connected to the bottom end of the denture body 1. A protective pad 18 is fixedly bonded to the inner top of the gingival veneer 2, and a plurality of evenly distributed buffer springs 19 are fixedly connected between the protective pad 18 and the denture body 1. Through the cooperation of the protective pad 18 and the plurality of buffer springs 19, a buffering and protective effect on the gums is achieved when grinding teeth.

[0026] The denture body 1 has four evenly distributed grooves 3 at its top, and anti-wear blocks 4 are slidably connected to the inner side of the grooves 3. The bottom end of the anti-wear blocks 4 is provided with an ejection mechanism, which includes a pressure sensor 5 fitted and installed at the bottom end of the anti-wear blocks 4. The top of the denture body 1 has a receiving groove 6 that communicates with the four grooves 3. The bottom end of the anti-wear blocks 4 is fixedly connected with an ejection rod 7, which passes through the inner side of the receiving groove 6 and contacts its bottom end. A motor 8 is fixedly installed at the center of the bottom end of the receiving groove 6, and a connecting shaft 9 is fixedly connected to the top output shaft of the motor 8. A rotating rod 10 and a pushing block 11 are fixedly connected to the outer wall of the connecting shaft 9 in sequence, and the pushing block 11 is located on the circular trajectory formed by the four anti-wear blocks 4. A sealing plate 17 is fixedly connected to the bottom end of the receiving groove 6 outside the connecting shaft 9 to seal and protect the motor 8.

[0027] By using the sliding groove 3, the anti-wear block 4, and the ejection mechanism in conjunction, the wearer can activate the pressure sensor 5 to monitor the surface pressure of the denture body 1 in real time before going to sleep at night. When the wearer grinds their teeth, the pressure sensor 5 detects that the pressure on a certain part of the denture body 1 exceeds the set value, and then controls the motor 8 to start and drive the connecting shaft 9 to rotate. The rotating rod 10 and the pushing block 11 rotate synchronously, so that the pushing block 11 moves to the underside of the anti-wear block 4 in the molar area. During the movement, the pushing block 11 pushes the ejection rod 7 from below, causing it to move upward. The anti-wear block 4 is pushed upward at the same time, which will lift up the teeth or other dentures that are in contact with the molars of the denture body 1, so that the denture body 1 is separated from them, thereby avoiding tooth damage caused by grinding and displacement of the denture body 1, ensuring normal use.

[0028] Furthermore, the bottom end of the ejector rod 7 is formed into a rounded edge structure, and the push block 11 is formed into an isosceles trapezoidal structure with a gentle slope. Through the structural cooperation of the ejector rod 7 and the push block 11, when the push block 11 rotates, its bottom sharp corner can be squeezed into the lower part along the bottom rounded edge of the ejector rod 7, and push the ejector rod 7 to move upward along its slope, thereby effectively achieving the effect of lifting the anti-wear block 4 upward.

[0029] In addition, an electrical stimulation head 16 is fitted inside the top of the anti-wear block 4, and the electrical stimulation head 16 is electrically connected to the pressure sensor 5. When the pressure sensor 5 detects that the pressure exceeds the standard, it can control the electrical stimulation head 16 to release a small current to stimulate the teeth that are grinding in contact with the denture body 1 to spring away, so as to help the anti-wear block 4 and the ejection mechanism achieve a better anti-wear effect.

[0030] Example 2: Based on Example 1, the bottom end of the receiving groove 6 is fixedly connected to the outer side of the four ejector rods 7 with a limiting arc plate 12, and a fixing rod 14 is fixedly connected between the inner side of the limiting arc plate 12 and the receiving groove 6. A sliding plate 13 is fixedly connected to the outer wall of the ejector rod 7, and the sliding plate 13 slides on the inner side of the limiting arc plate 12 and the outer side of the fixing rod 14. By fitting the limiting arc plate 12 to the outer side of the ejector rod 7, and by limiting the sliding of the sliding plate 13 with the limiting arc plate 12 and the fixing rod 14, the movement of the ejector rod 7 can be stably limited in the vertical direction, thereby ensuring the vertical stability of the anti-wear block 4 being pushed upward.

[0031] Furthermore, a pull-back spring 15 is fixedly connected between the bottom end of the slide plate 13 and the receiving groove 6, and the pull-back spring 15 is located outside the fixed rod 14. By setting the pull-back spring 15, when the pushing block 11 rotates to disengage from contact with the ejector rod 7, the ejector rod 7 can be pulled back to its original position. At the same time, it can ensure the stability of the ejector rod 7 and the anti-wear block 4 stored in the receiving groove 6 and the slide groove 3 during daily use.
