[0001] The present invention relates to a self-adjusting removable denture, in particular to a self-adjusting removable denture applied in the field of false teeth. Background Art
[0002] The professional name of removable denture is removable denture, including removable partial denture and full denture. It is a kind of prosthesis that patients can wear and take off by themselves, using the remaining natural teeth, mucosa and bone tissue under the base as support, relying on the retainer and base of the denture for retention, using artificial teeth to restore the shape and function of the missing teeth, and using the base material to restore the defective alveolar ridge, jawbone and the surrounding soft tissue shape.
[0003] In order to reduce the rate of foreign matter getting stuck, in the prior art, the two denture crowns are generally brought into contact with each other to minimize the gap.

[0007] In the above-mentioned adaptive adjustable removable denture, when chewing, its edge can automatically expand and fill the gaps between teeth, so that multiple dentures are in a tightly attached state, making the denture connection more stable. At the same time, the gaps between teeth are filled, which effectively prevents food residues from getting stuck in the gaps between teeth. When not chewing, it is in a relaxed state, which can improve the comfort of the user.
[0008] As a further improvement of the present application, the monitoring unit includes an inlay and a temperature sensor fixedly embedded in the middle of the upper end of the inlay. An internal pressure sensor is also installed on the upper end of the positioning block, and the sensing end of the internal pressure sensor faces upward and protrudes from the surface of the positioning block.
[0009] As a further improvement of the present application, the adaptive unit includes two variable seam layers whose edges are fixedly attached to the outer surface of the crown and a heating wire fixedly embedded inside the crown. The heating wire is electrically connected to the piezoelectric module. The two variable seam layers are respectively located on both sides of the crown and correspond to another adjacent crown.
[0010] As a further improvement of the present application, the variable seam layer has a double-layer structure, with one layer being made of a shape memory alloy and the other being made of an elastic sealing material, and the critical deformation temperature of the shape memory alloy is not lower than 40°C.

DETAILED DESCRIPTION
[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0029] The first implementation method:
[0030] Figure 1 An adaptively adjustable removable denture is shown, comprising a bracket 1 fitted with the gums, a base layer 2 fixedly connected to the bracket 1, a plurality of dentures 3 mounted on the base layer 2, a gap of 1-2 mm between two adjacent dentures 3, the presence of the gap facilitates subsequent cleaning of food residues, a micro control chip is integrated in the denture 3, a clasp 11 is fixedly connected to the upper end of the bracket 1 near the edge of the denture 3, when in use, the removable denture is clamped onto the user's adjacent real teeth by the clasp 11, so that the removable denture can be taken out of the oral cavity as a whole.
[0031] like Figure 2-3 The upper end of the base 2 is fixedly connected to a positioning block 33, and the upper end of the positioning block 33 is fixedly connected to a mounting column 7. The denture 3 includes a crown 31 and a monitoring unit embedded in the middle of the upper end of the crown 31. The monitoring unit includes an inlay 32 and a temperature sensor 301 fixedly embedded in the middle of the upper end of the inlay 32. The inlay 32 and the crown 31 are made of the same material. An internal pressure sensor 302 is also installed on the upper end of the positioning block 33. The sensing end of the internal pressure sensor 302 faces upward and protrudes from the surface of the positioning block 33. When chewing food, an extrusion force is generated, which causes the internal pressure sensor 302 to generate force data. According to the force data, the internal pressure sensor 302 can be used to measure the pressure of the internal pressure sensor 302. In order to effectively judge whether eating is in progress, an adaptive unit is also arranged on the outer periphery of the crown 31, and a piezoelectric module 8 is installed at the top of the mounting groove. The piezoelectric module 8 is electrically connected to the adaptive unit, and the monitoring unit and the adaptive unit are both connected to the microcontroller chip signal. During each chewing, the piezoelectric module 8 between the positioning block 33 and the crown 31 is squeezed, thereby generating current, which can supply power to the heating wire 4, thereby controlling the power supply thereof when necessary, thereby deforming the variable seam layer 6, wherein the piezoelectric module 8 is mainly composed of piezoelectric ceramics, etc., and its specific composition is the prior art, which will not be elaborated here.
[0032] In actual implementation, a battery can also be integrated in the crown 31 to store the current generated by each chewing and energize the heating wire 4 when needed.
[0033] The adaptive unit includes two variable seam layers 6 whose edges are fixedly attached to the outer surface of the crown 31 and a heating wire 4 fixedly embedded in the crown 31. The heating wire 4 is electrically connected to the piezoelectric module 8. The two variable seam layers 6 are respectively located on both sides of the crown 31 and correspond to another adjacent crown 31. The variable seam layer 6 is a double-layer structure, and one layer is made of shape memory alloy and the other layer is made of elastic sealing material. The critical deformation temperature of the shape memory alloy is not less than 40°C. When the user eats, the oral temperature can be monitored by the temperature sensor 301. When the food temperature is high, the variable seam layer 6 can be directly expanded to fill the gap between the two dentures 3. The gap between the two dentures is formed, so that food residues are not easy to enter the gap between the two. When the food is not chewed, the human body temperature is constant and below 40°C, and the gap-changing layer 6 is in its original state attached to the surface of the crown 31, so that the multiple dentures 3 are in a relaxed state, thereby reducing the compression on the skin in the oral cavity and improving the comfort. When the food temperature is low during chewing and the internal pressure sensor 302 generates data, the microcontroller chip can control the heating wire 4 to be energized, so that it gradually generates heat, thereby causing the gap-changing layer 6 to expand due to the heat, which can also achieve the effect of filling the gap between the two dentures 3 during chewing and reduce the occurrence of food getting stuck in the gap between the dentures 3.
[0034] The bottom of the crown 31 is provided with a mounting groove and a vertical groove 303. The vertical groove 303 is located above the mounting groove, and the two are connected to each other. The inner wall of the vertical groove 303 is also provided with an outer expansion ring groove 304. The inner wall above the outer expansion ring groove 304 is flush with the top of the vertical groove 303. A T-shaped locking rod 73 is fixedly connected to the center of the top of the vertical groove 303. The base layer 2 matches the mounting groove, the mounting column 7 matches the vertical groove 303, and the T-shaped locking rod 73 is connected to the middle of the mounting column 7. The mounting column 7 includes a column body 71 and a plurality of movable column petals 72 that slide elastically with the upper end of the column body 71. A reverse groove 701 is cut in the middle of the upper end of the column body 71. The reverse groove 701 matches the lower end of the T-shaped locking rod 73. The ends of the plurality of movable column petals 72 that are close to each other are all cut with arc grooves. The plurality of arc grooves form the reverse groove 701. The reverse groove 701 is coaxially arranged with the vertical hole 702. When the movable denture is taken out for cleaning as a whole, the crown 31 and the base can be selected according to actual needs. The layer 2 is separated and taken out for cleaning. The removable denture can be directly immersed in clean water at 50-70°C to soften the T-shaped locking rod 73. At this time, the clamping limiting force between the installation column 7 and the positioning block 33 and the outer expansion ring groove 34 becomes smaller, and the denture 3 can be directly pulled out. After cleaning, when installing, it is also immersed and softened, and then the crown 31 is clamped with the positioning block 33 so that it can smoothly enter the inverted groove 701 and the vertical hole 702. The larger the size of the cylinder 71, the more it will push the column petal 72 outward, causing it to move horizontally outward along the upper surface of the cylinder 71, and then embed it into the outer expansion ring groove 34, thereby achieving a stable clamping connection between the crown 31 and the heating wire 4, so that when chewing food, the denture 3 can remain stable after being subjected to force and is not easy to loosen. At the same time, after the T-shaped locking rod 73 enters the inverted groove 701 and cools down and solidifies, a limiting structure similar to a barb can be generated, so that the T-shaped locking rod 73 is limited in the longitudinal direction, so that the denture 3 is not easy to loosen.
[0035] In addition, it is not necessary to remove the dentures 3 and clean them one by one every day. Since there is a certain gap between two adjacent dentures 3, it is convenient for cleaning. At certain time intervals, multiple dentures 3 can be removed for deep cleaning separately, or when the residue in the tooth gap is difficult to remove, the dentures 3 can be removed and cleaned separately. Compared with the complete overall cleaning of the removable dentures in the prior art, it can effectively ensure oral health.
[0036] The lower inner wall of the outwardly expanded annular groove 304 is flush with the neck of the T-shaped locking rod 73 and the rod connection, and the outer diameter of the rod of the T-shaped locking rod 73 is larger than the inner diameter of the vertical hole 702, so that after it is embedded in multiple columns 71, it can squeeze the columns 71 to expand and move outward, thereby embedding in the outwardly expanded annular groove 34 to achieve snap-on connection.
[0037] Among them, the elastic sliding of the movable column petal 72 and the column body 71 can be understood as a sliding connection, and a spring is installed between the sliding parts so that it can slide outward when squeezed, and can be reset due to the spring reset after being squeezed; and the lateral depth of the outward expansion annular groove 304 is greater than the size difference between the vertical hole 702 and the rod part of the T-shaped locking rod 73 and the inner diameter of the vertical hole 702.
[0038] The T-shaped locking rod 73 includes an internal shaping rod and an adaptive sleeve wrapped around the outer end of the shaping rod. The adaptive sleeve is a high-temperature resistant elastic sleeve filled with a thermoplastic resin material, and the melting point of the thermoplastic resin material is 50-70°C. The internal shaping rod is mainly used for shaping, so that after the outside of the T-shaped locking rod 73 is hot-melted, the whole can roughly maintain a vertical state, so that the T-shaped locking rod 73 can be stably inserted into the vertical hole 702.
[0039] It is worth noting that the micro-control chip in this removable denture can be connected to the user's mobile phone signal, so that various data can be viewed on the mobile phone, allowing the user to understand dental abnormalities in a timely manner based on the various data.
[0040] In addition, based on the data from the internal pressure sensor 302, the user's tooth usage habits can be roughly summarized and judged, which is convenient for adjusting the user's bilateral uniform tooth usage and reducing the situation of unilateral concentrated tooth usage.
[0041] In summary, Figure 7-Figure 9 It is shown that in the above-mentioned self-adaptive adjustable removable denture, through the coordinated setting of the monitoring unit and the self-adaptive unit, when in use, the two adjacent dentures 3 are first set in a non-contact state. When chewing, electricity can be generated to supply power to the heating wire 4, so that it heats the denture 3, and then the heating wire 4 is heated and deformed outward, thereby filling the gap between the teeth, so that the multiple dentures 3 are in a tightly attached state, making the denture connection more stable, and at the same time the gap between the teeth is filled, effectively preventing food residues from getting stuck in the gap between the teeth, such as Figure 7 When not chewing, the gap between the two dentures 3 is relatively large. Rinsing the mouth directly after a meal can quickly wash away most of the foreign matter between the teeth, and the denture 3 is in a relaxed state, which can improve the comfort of the user.
[0042] The second implementation method:
[0043] Based on the first embodiment, this embodiment adds an external pressure sensor 5, and the rest of the parts are consistent with the first embodiment.
[0044] Fig.10It is shown that two groups of external pressure sensors 5 are fixedly embedded on the outer surface of the crown 31, and the two groups of external pressure sensors 5 correspond to the two variable seam layers 6 respectively, and the two groups of external pressure sensors 5 are both located on the inner side of the variable seam layer 6. There are multiple external pressure sensors 5 in each group. Under the setting of the external pressure sensors 5, it is possible to monitor whether foreign objects are stuck between the two dentures 3. When foreign objects are stuck between the two dentures 3, the foreign objects will squeeze the corresponding external pressure sensors 5, thereby increasing the force data thereon. Based on this, it can serve as a reminder for the user, so that the user can promptly detect the presence of foreign objects when there is no foreign body sensation, which facilitates timely cleaning and improves oral safety.
[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
