Abstract
Description
Technical Field
[0001] This invention relates to the field of denture technology, and in particular to a complete denture device equipped with an auxiliary retention structure. Background Technology
[0002] Complete dentures are removable prostheses designed for patients who have lost all of their upper and lower jaw teeth. They are primarily used to help restore the patient's oral function and appearance. Traditional complete dentures typically consist of two parts: artificial teeth and a denture base. Their retention principle relies on the suction force generated by the close fit and marginal sealing between the denture base and the edentulous jaw mucosa (i.e., the alveolar bone), similar to the negative pressure generated by cupping or suction cup hooks. This suction force adheres to the alveolar ridges of the upper and lower jaws, and the denture retains itself and bears the occlusal pressure, thus restoring the patient's chewing, speech, and appearance functions.
[0003] In clinical applications, when a patient's remaining alveolar ridge is low, the mucosa is soft, or the quality of saliva secretion is low, it is difficult for the denture to generate ideal adhesion, which can easily lead to loosening and falling out during use, mucosal tenderness, and other problems, making it impossible for the patient to eat normally using the denture. The incidence of this situation in the clinical treatment of complete dentures is about 20%. In order to address this situation, this invention proposes a complete denture device equipped with an auxiliary retention structure to solve the above problems. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a complete denture device equipped with an auxiliary retention structure. The patient wears the auxiliary retention structure when eating and removes it when not eating or when it is inconvenient to wear it, thus solving the problem of being unable to eat normally due to poor denture adhesion.
[0005] To achieve the above objectives, the present invention provides a complete denture device equipped with an auxiliary retention structure, including a denture base and a retention headframe.

[0035] Please see Figures 1-9 A complete denture device equipped with auxiliary retention structures includes a base frame 28 and a retention head frame 30. The base frame 28 is installed on the gum and artificial teeth 29 are installed on the base frame 28. The retention head frame 30 is used to assist in fixing the position of the base frame 28, which can help patients with unsatisfactory denture suction to improve suction, thereby improving chewing feasibility and eating comfort. It can be worn before each meal and can be removed when not eating. The operation is simple and convenient. The base frame 28 includes a maxillary base frame 2 and a mandibular base frame 1. Both the maxillary base frame 2 and the mandibular base frame 1 are provided with connecting grooves 3 on the side near the corner of the mouth (the corner of the mouth refers to the two sides of the lips). The connecting grooves 3 are used for the insertion and installation of denture stabilizing bars 14.
[0036] The headrest 30 includes a headband 12, which includes a loop 122. A limiting strap 121 is fixedly installed inside the loop 122. First adjustment straps are fixedly installed on the front and rear sides of the loop 122, primarily for adjusting and limiting the position from both sides of the face. The first adjustment strap 23 includes a first fixing strap 15 and a first movable strap 19. The first fixing strap 15 is fixedly connected to the loop 122, and the first movable strap 19 is fixedly connected to the second adjustment strap 24. A first Velcro fastener is fixedly installed on the inner side of the first fixing strap 15, and a second Velcro fastener 17 is fixedly installed on the outer side of the first movable strap 19. The first and second Velcro fasteners 17 are adhered and fixed together. The first fixing strap 15 is made of nylon, which has low elasticity and its size can remain largely unchanged. The first movable strap 19 is made of polyester fiber, which has greater elasticity and can be easily adapted to different head sizes of different patients, offering a wide range of applications and high user comfort.
[0037] A second adjustment strap 24 is fixedly installed at the bottom of the first adjustment strap 23. The second adjustment strap 24 mainly extends from the back of the user's head. The second adjustment strap 24 includes a second fixed strap 21 and a second movable strap 33. The second fixed strap 21 is fixedly connected to the first movable strap 19, and the second movable strap 33 is fixedly connected to the connecting strap 18. A front hook and loop fastener 20 is fixedly installed on the outer side of the second movable strap 33, and a back hook and loop fastener is fixedly installed on the inner side of the second fixed strap 21. The front hook and loop fastener 20 and the back hook and loop fastener are glued together. Several first blocks 16 are evenly fixedly installed on the front of the first fixed strap 15, and several second blocks 22 are evenly fixedly installed on the front of the second fixed strap 21. Both the first blocks 16 and the second blocks 22 are arranged in an I-shape. The second blocks 22 and the first... Elastic elastic bands 13 are fitted onto the block 16. A connecting strap 18 is fixed between the two second adjustment straps 24. Elastic elastic bands 13 are installed on the side walls of the first adjustment strap 23 and the second adjustment strap 24. The elastic elastic bands 13 are connected to denture stabilizing rods 14. Denture stabilizing rods 14 are inserted into the connecting grooves 3. By adjusting the length of the first adjustment strap 23 and the second adjustment strap 24, the head strap 12 can be comfortably fixed on the patient's head, which can adapt to different patients and different jawbone shapes. Denture stabilizing rods 14 are inserted into the connecting grooves 3 of the denture base frame to prevent the denture from loosening and falling off during use.
[0038] As an improvement to the above technical solution, a first retention mesh 5 is fixedly installed on the side of the maxillary denture base 2 that contacts the gum, and a second retention mesh 6 is fixedly installed on the side of the mandibular denture base 1 that contacts the gum. The initial soft lining material, a mixture of powdered solid and liquid substances in a specific ratio, is evenly spread on the retention mesh and the edges of the denture base 28. It is then quickly placed in the correct position within the oral cavity and the edges are shaped. After approximately 5-10 minutes, the soft lining material hardens and stabilizes, adhering tightly to the gum mucosa on one side and fusing with the denture base 28 on the other. The base frame 28 is integrated to form a stable state similar to rubber skin, thereby achieving a personalized fit to the patient's gums. The base frame 28 is available in different sizes such as large, medium and small to accommodate alveolar ridges of different widths and heights. Screw channels 4 are provided on both sides of the upper end and the middle of the lower end of the maxillary base frame 2 and the mandibular base frame 1. Screw channels 4 are also provided at the corresponding positions of the artificial tooth 29 and the base frame 28. The function of the screw channels 4 is to fix the artificial tooth 29 to the base frame 28, so that the artificial tooth is stably installed on the base frame.
[0039] Artificial teeth 29 are installed on the maxillary denture base 2 and the mandibular denture base 1 respectively. The artificial teeth 29 include a retention plate 8, which is roughly U-shaped to adapt to the edentulous jawbone and comes in different sizes to roughly match the denture base 28. Retention holes 7 are provided on both sides of the upper end of the retention plate 8. Tooth beads 9 are evenly fixed on the retention plate 8. The tooth beads 9 are divided into 14 maxillary and 14 mandibular tooth beads according to their positions and are arranged on the retention plate 8 according to the normal occlusal curve. Retention screws 11 are provided in the retention holes 7. The retention plate 8 is fixed to the denture base 28 by screwing the retention screws 11 into the screw channels 4. Screw channels 4 are provided on both sides of the upper end and the middle of the lower end of the denture base. Retention holes 7 are provided on both sides of the upper end of the retention plate 8. The artificial teeth 29 are fixed to the denture base 28 by screwing the retention screws 11 into the screw channels 4, ensuring the stable installation of the artificial teeth 29 on the denture base.
[0040] As an improvement to the above technical solution, a handle 10 is detachably installed on the bottom of the retention plate 8, and a threaded rod 31 is fixedly installed on the top of the handle 10. The threaded rod 31 is threaded into the threaded groove 32, which is located at the bottom of the retention plate 8. The handle 10 makes it easier for doctors to operate when installing and adjusting the artificial tooth 29. At the same time, the handle 10 is easy to install and remove. The handle 10 can be removed after the artificial tooth 29 is installed.
[0041] As an improvement to the above technical solution, the internal structures of the loop 122 and the limiting strap 121 are the same. The loop 122 includes a base layer 1222, and a buffer layer 1224 is fixedly provided at the bottom of the base layer 1222, which improves the buffering performance of the loop 122 and the limiting strap 121, avoiding head pressure pain and wearing discomfort. An anti-slip layer 1225 is fixedly provided on the inner side of the buffer layer 1224. The anti-slip layer 1225 improves the friction between the inner side of the loop 122 and the limiting strap 121 and the head when wearing, preventing slippage between the loop 122 and the limiting strap 121 during wear. The sliding base layer 1222 has an antibacterial layer 1221 fixedly installed on the top. The antibacterial layer 1221 improves the antibacterial performance of the loop 122 and the limiting belt 121. The base layer 1222 is made of polyethylene material, the buffer layer 1224 is a sponge pad, and multiple ventilation holes 1223 are evenly arranged on the top of the loop 122. The ventilation holes 1223 pass through the antibacterial layer 1221, the base layer 1222, the buffer layer 1224 and the anti-slip layer 1225 in sequence. The ventilation holes 1223 improve the breathability of the loop 122 and the limiting belt 121 when worn.
[0042] As an improvement to the above technical solution, the denture stabilizing rod 14 includes a bent rod 143. One end of the bent rod 143 is fixedly provided with a connecting rod 141, and the other end of the bent rod 143 is fixedly provided with an insert rod 142. The insert rod 142 is inserted into the connecting groove 3. A sleeve 25 is fixedly provided through the connecting rod 141. An adjusting rod 27 is threaded into the sleeve 25. A rotating shaft 26 is rotatably provided at the outer end of the adjusting rod 27. The end of the rotating shaft 26 away from the adjusting rod 27 is fixedly connected to the elastic band 13. By adjusting the depth of the adjusting rod 27 inserted into the sleeve 25, the tension of the elastic band 13 can be changed to ensure that the denture fits firmly against the gums without affecting the normal chewing movement of the mandible.
[0043] Working principle and usage of this invention:
[0044] In use, a first retention mesh 5 is fixedly installed on the side of the maxillary denture base 2 that contacts the gum line, and a second retention mesh 6 is fixedly installed on the side of the mandibular denture base 1 that contacts the gum line. The initial soft lining material, a mixture of powdered solid and liquid substances in a specific ratio, is evenly spread on the retention mesh and the edges of the denture base 28. It is then quickly placed in the correct position within the mouth and the edges are shaped. After approximately 5-10 minutes, the soft lining material hardens and stabilizes, adhering tightly to the gum mucosa on one side and fusing with the denture base 28 on the other, forming a stable, rubber-like structure. This achieves a personalized fit between the denture base 28 and the patient's gum line. The denture base 28 is available in various sizes (small, medium, large) to accommodate alveolar ridges of different widths and heights. Screws are located on both sides of the upper end and the middle of the lower end of the denture base. The upper end of the retention plate 8 is provided with retention holes 7 on both sides. The retention screw 11 is screwed into the screw channel 4 to fix the artificial tooth 29 to the base bracket 28, ensuring the stable installation of the artificial tooth 29 on the base bracket. The top of the handle 10 is fixedly provided with a threaded rod 31, which is threaded into the threaded groove 32. The handle 10 makes it easier for doctors to operate when installing and adjusting the artificial tooth 29. At the same time, the handle 10 is easy to install and remove. The handle 10 is removed after the artificial tooth 29 is installed. The headband 12, the first adjustment band 23 and the second adjustment band 24 are provided. The connecting band 18 is fixed between the two second adjustment bands 24. The length of the first adjustment band 23 and the second adjustment band 24 is adjusted so that the headband 12 is comfortably fixed on the patient's head, which can be adapted to different patients and different jaw shapes.
[0045] Specifically, the length is adjusted by attaching the first and second Velcro 17 together, and by attaching the front and back Velcro 20 together. Elastic bands 13 are installed on the sidewalls of the first and second adjustment bands 23 and 24, providing elastic support. The denture stabilizing rod 14 is inserted into the connecting groove 3 of the denture base. Adjusting the depth of the adjusting rod 27 inserted into the sleeve 25 changes the tension of the elastic band 13, ensuring the denture fits firmly to the gum without affecting normal chewing movements of the mandible. The denture stabilizing rod 14 can be available in various shapes to suit patients with different mouth cleft sizes. The retention head... The frame 30 provides additional fixing force through the elastic band 13 and the denture stabilizing bar 14 to prevent the denture from loosening and falling off during use. The buffer layer 1224 improves the cushioning performance of the band 122 and the limiting band 121, avoiding head pressure pain and wearing discomfort. The anti-slip layer 1225 improves the friction between the inner side of the band 122 and the limiting band 121 and the head when wearing, preventing the band 122 and the limiting band 121 from slipping. The antibacterial layer 1221 improves the antibacterial performance of the band 122 and the limiting band 121. The ventilation holes 1223 improve the breathability of the band 122 and the limiting band 121 when wearing.
[0046] The complete denture device of the present invention with a wearing auxiliary retention structure allows the denture retaining rod 142 to be inserted into the connecting groove 3 of the base bracket when eating. Then, the tension of the elastic band 13 is adjusted by the adjusting rod 27, so that the denture is stably attached to the gum without affecting the normal chewing movement of the mandible. The retention head frame can then be worn. After wearing, the denture's adhesion is improved, making it easier for the user to chew, enabling normal eating and improving the quality of life.
[0047] When not eating, the headrest can be removed by rotating the adjusting rod 27 out of the sleeve 25, reducing the tension of the elastic band. Then, the insert 142 of the denture retaining rod 14 can be pulled out of the connecting slot 3 of the base bracket 28. The operation is convenient and simple.
