Description

Technical Field

[0001] The invention belongs to the technical field of medical products and relates to an intelligent anti-lost dental restoration. Background Art

[0002] Every day, there are cases of children, teenagers, women and other vulnerable groups getting lost. They are either trafficked or kidnapped and are in danger. In addition, as the elderly age, they suffer from cardiovascular and cerebrovascular diseases, which lead to memory loss. They may get lost when they go out, which brings great trouble to their families. Police, soldiers, war correspondents, scientific explorers, people traveling or visiting abroad, etc. may be in danger or get lost. After a natural disaster or emergency, finding survivors and victims and verifying their identities become very difficult problems.

[0003] There are already items containing GPS tracking devices on the market, but the existing products have a single function and can only be used to query the real-time location information of the monitored person. They do not have the function of storing the patient's identity information, nor can they automatically alarm the monitoring personnel, making them inconvenient to use. In addition, in the event of abduction or kidnapping, the personal belongings may be taken away, and the positioning and alarm functions cannot be used. Summary of the invention

[0004] Based on the above deficiencies in the prior art, the purpose of the present invention is to provide an intelligent anti-lost dental restoration, which solves the problems that the existing tracking devices have single functions, are inconvenient to use, and are easy to be discovered.

[0005] In order to achieve the above-mentioned object of the invention, the present invention specifically adopts the following technical solutions.

[0006] An intelligent anti-lost dental prosthesis, comprising a prosthesis, and a positioning and sensing device arranged inside the prosthesis;

[0007] The restoration is installed on a tooth or an implant in the patient's mouth;

[0008] The patient uses the prosthesis normally, and the positioning and sensing devices in the prosthesis locate the patient's position and send the position information to the guardian's computer and / or mobile phone terminal.

[0009] The positioning and sensing device comprises a device housing, a positioning module arranged in the device housing, and a wireless communication module;

[0010] The positioning module is a GPS or Beidou dual positioning module, which can receive positioning signals from the GPS or Beidou system and send the positioning signals to the monitoring person's computer and / or mobile phone terminal through the wireless communication module.

[0011] The positioning and sensor device also includes a pressure sensing module and a main control module arranged in the housing of the device;

[0012] The positioning and sensor device is fixedly arranged at the bottom position inside the restoration, and the pressure sensing module is embedded inside a side of the device shell that can withstand the tooth biting pressure when the patient's teeth are biting;

[0013] The pressure sensing module senses the patient's tooth occlusion pressure, and transmits the sensed patient's tooth occlusion pressure to the main control module in real time.

[0014] A first pressure threshold and a first time threshold are preset in the main control module. When the patient encounters an emergency and is unable to call the police in time with a mobile phone, the patient bites his teeth hard; when the main control module determines that the bite pressure sensed by the pressure sensing module is higher than the first pressure threshold and lasts longer than the preset first time threshold, the main control module sends an alarm message and the patient's location information to the guardian's computer / mobile phone through the wireless communication module, wherein the preset first pressure threshold should be greater than the pressure value that the pressure sensing module is borne when the patient chews normally and when the patient subconsciously clenches his teeth when encountering an emergency.

[0015] A second pressure threshold and a second time threshold are preset in the main control module. When the main control module determines that the bite pressure sensed by the pressure sensing module continues for a second pressure threshold time longer than the preset second time threshold, the main control module sends an alarm message and the patient's location information to the guardian's computer / mobile phone through the wireless communication module, wherein the preset second pressure threshold is not greater than the pressure value that the pressure sensing module is subjected to when the patient chews normally.

[0016] The alarm information is sent once every minute until the alarm condition is no longer met;

[0017] The first time threshold and the second time threshold can be modified through the guardian's computer and / or mobile phone terminal.

[0018] The positioning and sensor device also includes an information storage module and a power supply module disposed in the device housing;

[0019] The information storage module is connected to the main control module and is used to store the patient's personal information, and retrieve the information in the information storage module through the guardian's computer and / or mobile phone;

[0020] The patient's personal information includes: ID number, household registration information, passport number, driver's license number, height, facial photo, birthmark, fingerprint, blood type, DNA sequence, name, address and phone number of emergency contact;

[0021] The power module provides the required power for each module in the positioning and sensor device.

[0022] The restoration can be made into a variety of irregular shapes and different colors according to the patient's tooth defects or tooth loss conditions to repair different tooth defects;

[0023] The housing of the positioning and sensing device can be made into a variety of irregular shapes according to the patient's tooth defects or tooth loss conditions, and can be made into different colors according to the color of the patient's dentin and the color of the patient's teeth.

[0024] The device shell is manufactured by 3D printing.

[0025] The restoration can be made as a fixed restoration or a removable restoration.

[0026] Among them, the fixed prosthesis is fixed to the teeth or implants in the oral cavity by chemical and / or mechanical action, and is called a fixed denture because the patient cannot remove it by himself;

[0027] The removable prosthesis can be removed by the patient and then worn in the oral cavity, which is also called a removable denture.

[0028] The chemical action, i.e. fixing the restoration to the tooth or implant in the oral cavity by means of a cement or adhesive;

[0029] The mechanical action is to fix the restoration to the teeth or implants in the oral cavity by means of a fixing device;

[0030] The restoration can also be mounted on a dental implant and can be made of a material that is transparent to communication signals.

[0031] The main control module, positioning module, information storage module, pressure sensing module, wireless communication module and power module are all located inside the device housing; the main control module is connected to the positioning module, information storage module, pressure sensing module and wireless communication module respectively, and the power module is connected to the main control module, positioning module, information storage module, pressure sensing module and wireless communication module respectively; the wireless communication module is connected to the guardian's computer or mobile phone by wireless means;

[0032] The device housing protects the modules in the device housing, prevents corrosion from the outside, and withstands the occlusal pressure transmitted from the restoration;

[0033] The power module can realize the wireless charging function.

[0034] The restoration is used to repair tooth defects and can also be used to repair one or several missing teeth in the dentition.

[0035] The fixed restoration is made by 3D printing or artificial layer-by-layer stacking of restoration materials outside the patient's mouth, and can also be made by artificial layer-by-layer stacking of restoration materials inside the patient's mouth, and the positioning and sensing device is embedded in the restoration to obtain an intelligent fixed restoration, and the intelligent fixed restoration is bonded to the teeth by a special dental adhesive.

[0036] The movable restoration can be manufactured by 3D printing, and the positioning and sensing devices can be embedded into the restoration.

[0037] The movable restoration can be manufactured by using traditional techniques, and then the positioning and sensing devices can be embedded into the restoration by manual operation.

[0038] The traditional process includes the steps of: casting or bending the clasp, arranging the teeth, making a wax base, boxing and embedding, heat treatment and the like.

[0039] A relatively large GPS antenna can be embedded in the resin base of the movable restoration, thereby providing better communication for the GPS positioning module.

[0040] The restoration can also be installed on a dental implant. The patient has no diseased teeth and voluntarily installs the implant and restoration.

[0041] The restoration is made of a material capable of penetrating communication signals, such as a resin material, or a ceramic material.

[0042] The pressure sensing module comprises a graphene pressure sensor and an integrated circuit; the integrated circuit converts the pressure obtained by the graphene pressure sensor into a corresponding voltage signal or a current signal.

DETAILED DESCRIPTION

[0057] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Patients with missing teeth need dental restorations to repair the missing or missing teeth. Dental restorations containing storage and positioning devices are embedded in the patient's teeth or dentures. They are realistic in shape and color, and are very hidden in position. Non-professionals cannot find them. They are not easy to be found in cases of trafficking, kidnapping, etc. Dental restorations have the characteristics of being sealed and waterproof, which can protect the storage and positioning devices. After encountering natural disasters or emergencies, they are not easy to leave the human body, thus playing a positioning and alarm role. The storage and positioning device contains a pressure sensing module, which can record the chewing pressure of the patient's teeth with restorations installed. In critical moments, the user can bite the teeth hard for a certain period of time to call the police in time, avoiding the situation where the emergency cannot be reported in time, and the best time to find them after disappearance is missed. If the pressure receptor does not feel the pressure signal for a certain period of time, it prompts the user that he has not chewed or eaten for a long time, and the alarm will be called in time, avoiding the situation where the alarm is not called as soon as possible after disappearance, and the body and wreckage are difficult to find after death.

[0068] A second pressure threshold and a second time threshold are preset in the main control module 4. When the main control module determines that the bite pressure sensed by the pressure sensing module continues for a second pressure threshold longer than the preset second time threshold, the main control module 4 sends an alarm message and the patient's location information to the guardian's computer / mobile phone through the wireless communication module 8, wherein the preset second pressure threshold is not greater than the pressure value that the pressure sensing module is subjected to when the patient chews normally.

[0069] The alarm information is sent once every minute until the alarm condition is no longer met;

[0077] The pressure sensing module 6 converts the pressure obtained by the patient's teeth clenching into a voltage signal or current signal of corresponding magnitude, and transmits the voltage signal or current signal to the main control module 4 in real time;

[0078] The wireless communication module 8 completes the communication between the main control module and the guardian's computer or mobile phone;

[0079] The power supply module 9 supplies power to each module of the restoration to ensure the normal operation of the restoration.

[0098] Example 1

[0099] like Figure 1 , 2 As shown in , 3, 4, and 10, the anti-lost restoration disclosed in this embodiment 1 includes a restoration 1, in which a positioning and sensing device 2 is arranged, and the positioning and sensing device includes a device housing 3, a main control module 4, and the main control module is respectively connected to a GPS Beidou dual positioning module 5, a pressure sensing module 6, an information storage module 7, a wireless communication module 8, and a power supply module 9. This embodiment 1 is a case of tooth defect repair of a permanent molar using a restoration 1, and caries occurs on the occlusal and adjacent surfaces of the affected tooth. The device housing 3 of the positioning and sensing device is made by 3D printing with a special dental resin, and the restoration 1 is made outside the patient's oral cavity by 3D printing or layer-by-layer stacking with a dental restoration resin material, so that the positioning and sensing device 2 and its device housing 3 are embedded in the restoration 1. As shown Figure 1As shown, in the adjacent occlusal cavity, in order to facilitate the bearing of chewing pressure, aesthetics and sealing, the positioning and sensing device 2 and its device housing 3 are placed at the bottom of the restoration 1. Figure 1 , as shown in FIG. 2 , in this embodiment, the bottom of the horizontal part of the restoration is the bottom of the horizontal part of the device housing, and the inner side wall of the restoration is the inner side wall of the device housing. In order to facilitate the retention and pressure bearing of the restoration 1 and the positioning and sensing device 2 and its device housing 3, the shape requirements of the positioning and sensing device housing 3 and the restoration are as follows: Figure 1 As shown, in order to retain and withstand pressure, the bottom wall and top wall of the device housing 3, that is, the upper and lower horizontal surfaces, must be flat. In order for the restoration to be smoothly placed in the tooth, the shape of the restoration 1 and the device housing 3 must be slightly expanded outward, the four longitudinal walls are outward, and the cross-sectional view is a trapezoid with a large occlusal edge and a small bottom; but in order to strengthen the retention effect and prevent the restoration from falling off, the four longitudinal surfaces of the device housing and the restoration must be close to parallel and as perpendicular to the horizontal plane as possible. Combining the above two points, the angle of the shape of the restoration 1 and the device housing 3 that expands outward cannot be large. For restorations made of composite resin materials, the outward expansion should be 0-20 degrees. Figure 1 , the included angle is 12; the abduction can be 2-20 degrees, which is conducive to the complete placement of the restoration (i.e. the restoration is worn on the tooth) and at the same time improves the accuracy and adaptability of the restoration. Figure 2 As shown, taking the restoration made of resin material as an example, the buccal wall 15 and the lingual wall 16 of the restoration 1 and the device housing 3 are slightly opened outward by 0-20 degrees. Figure 2 As shown, the included angle 12 forms a trapezoid with the occlusal side slightly larger than the gingival side. In order to smoothly place the restoration into the tooth, to retain it, to enhance the resistance at the junction of the distal surface and the occlusal surface of the restoration, and to enable the line angle 10 between the restoration 1 and the device housing 3 to withstand greater shear force, the thickness of the restoration here is made thicker. Figure 1 As shown, the two axial walls 11 are slightly inclined 2-20 degrees toward the pulp cavity 14 and are parallel to each other; in order to enhance the resistance of the junction between the distal surface and the occlusal surface of the restoration, as shown in FIG. Figure 1 As shown, the line angle 10 where the bottom wall of the horizontal part of the device housing 3 intersects with the shaft wall 11 and the line angle 10 where the top wall of the horizontal part intersects with the shaft wall 11 should be rounded; in order to increase the resistance, as shown in FIG. Figure 1 As shown, the occlusal and proximal surfaces of the device housing 3 and the restorative material covering the surface of the device housing 3 must have a certain thickness to prevent them from being crushed. The occlusal surface thickness of a restoration made of composite resin material (i.e., the material thickness of the occlusal surface of the device housing 3) is at least 2mm, and the occlusal surface thickness of a restoration made of all-ceramic material is at least 1.5mm; the proximal surface thickness of a resin restoration (i.e., the thickness of the thickest part of the proximal surface of the restoration, the vertical distance from the axial wall 11 of the restoration to the proximal contact area of ​​the tooth) is up to 1mm, and the proximal surface thickness of an all-ceramic restoration is at least 1.5mm. Therefore, Figure 1 As shown, the outer part of the adjacent surface of the device housing 3 should be within the dentin and should not exceed the enamel-dentin junction 13. Figure 1 As shown in FIG. 2 , the pressure sensing module 6 is installed inside the fixed restoration 1, at the top of the positioning and sensing device 2. Since the central fossa of the occlusal surface is the area with the greatest chewing pressure, as shown in FIG. Figure 1 As shown in FIGS. 2 and 4 , the pressure sensing module 6 is inside the restoration 1 and is located at the position of the central fossa of the occlusal surface. If the tooth defect does not reach the central fossa, the pressure sensing module should be set in the area closest to the central fossa. Figure 3 , Figure 4 As shown, from the occlusal view, the edges of the restoration and the edges of the device housing 3 are rounded curves. The storage positioning device 2 and the device housing 3 are embedded in the restoration 1, and the restoration 1 and the tooth are bonded to each other by a resin adhesive, so that it is embedded in the tooth. According to the color of the patient's teeth, by comparing with the color of the VITA colorimetric plate of dental resin material, the restoration and the device housing of the positioning and sensing device are designed to be A3 color. The patient can use the restoration normally, and the positioning device in the restoration can locate the patient's position and send the position information to the guardian's computer and / or mobile phone. The pressure sensing module in the restoration converts the patient's chewing pressure into a voltage / current signal, and the signal is transmitted to the main control module 4. When the set threshold is not exceeded, the main control module will not issue an alarm signal. When encountering emergencies such as kidnapping, natural disasters, etc., and the patient is unable to call the police in time with a mobile phone, he can bite his teeth hard for a certain period of time so that the signal transmitted to the main control module 4 by the pressure sensing module is higher than the high pressure threshold, and the duration of the high pressure signal is longer than the preset first time threshold. The signal sent by the pressure sensing module in the repair body is transmitted to the main control module 4, and the main control module 4 promptly sends the alarm information to the guardian's computer / mobile phone through the wireless communication module, and the alarm information is sent every one minute until the patient recovers normal chewing pressure.

[0100] Example 2

[0101] like Figure 5 , Figure 6As shown, the anti-lost restoration disclosed in this embodiment 2 includes a restoration 1, in which a positioning and sensing device 2 is provided, the positioning and sensing device includes a device housing 3, a main control module 4, and the main control module is respectively connected to a GPS Beidou dual positioning module 5, a pressure sensing module 6, an information storage module 7, a wireless communication module 8 and a power module 9, and is used to repair the tooth defect of the root canal treated tooth of the mandibular second deciduous molar. The device housing 3 of the positioning and sensing device is made by 3D printing with dental special materials, and the restoration 1 is made by 3D printing or artificial layer-by-layer stacking outside the patient's oral cavity using dental special materials. The difference between embodiment 2 and embodiment 1 is that the patient is a child, and the affected tooth is a deciduous molar that has been treated with a root canal 20. In order to facilitate resistance, beauty and sealing, the positioning and storage device 2 and its device housing 3 are placed at the bottom of the restoration 1. The device housing 3 of the positioning and sensing device 2 and the shape of the restoration 1 are as follows: the buccal wall 15 and the lingual wall 16, the mesial wall 18 and the distal wall 19 are slightly inclined outward by about 2-20 degrees, such as Figure 5 As shown in the figure, the occlusal surface is larger than the tooth neck, forming a trapezoid; for retention and resistance, the bottom of the restoration, that is, the top of the device shell, is straight. Figure 5 As shown, the outer shape of the part where the device housing 3 and the tooth neck shoulder collar 17 meet is an outward and smooth curve; in order to prevent the restoration from affecting the replacement of future permanent teeth, the positioning and sensing device 2 and its device housing 3 are placed in the pulp chamber of the deciduous tooth where the root canal 20 treatment has been completed, and not in the root canal 20. Figure 5 As shown, the pressure sensing module 6 is installed inside the fixed restoration 1, at the top of the positioning and sensing device 2, at the position of the central fossa of the occlusal surface in the direction of the tooth crown. The restoration 1 is finally bonded to the teeth using a dental adhesive. According to the color of the patient's teeth, the device shells of the restoration 1 and the positioning and sensing device 2 are designed to be A2 color by comparing the color of the dental resin material VITA colorimetric plate. The mandibular second deciduous molar will be replaced by permanent teeth in a certain period of time, and the deciduous teeth can fall off by themselves. If they do not fall off in time, the patient needs to return to the doctor at a certain time, and the doctor will extract the deciduous teeth in time. Take out the restoration and storage positioning device in the fallen deciduous teeth or the extracted deciduous teeth, and the storage positioning device can be installed in the new restoration for continued use, provided that the shape, size and color of the storage positioning device shell meet the requirements of the new restoration. Children can use the restoration normally at ordinary times. The positioning device in the restoration can locate the patient's position and send the position information to the guardian's computer and / or mobile phone. Multiple guardians can be set at the same time, and the information is sent to the computer and / or mobile phone terminals of multiple relatives such as mothers and fathers.

[0102] Example 3

[0103] like Figure 7As shown in Figures 8 and 9, the intelligent anti-lost restoration disclosed in this embodiment 3 includes a restoration 1, in which a positioning and sensing device 2 is provided, the positioning and sensing device includes a device housing 3, a main control module 4, and the main control module is respectively connected to a GPS Beidou dual positioning module 5, a pressure sensing module 6, an information storage module 7, a wireless communication module 8 and a power supply module 9, which is used to repair the missing teeth of the patient's mandibular first molar. The device housing 3 of the positioning and sensing device 2 is made by 3D printing outside the patient's mouth using dental restoration materials. The movable restoration can be made by 3D printing outside the patient's mouth. It can also be made by traditional technology, and then the resin material under the denture is ground off, the positioning and sensing device 2 is placed, and then the self-curing resin material is placed to polymerize it, and the denture and the positioning sensing device 2 are connected. The difference between Example 3 and Examples 1 and 2 is that, as Figure 7 As shown, Example 3 is a removable prosthesis, that is, a denture that can be taken off by oneself and then worn in the mouth. The prosthesis is used to repair the missing teeth of the mandibular first molar. Figure 8 The restoration is along Figure 7 A cross-sectional view of the line in . Figure 8 As shown, the positioning and sensor device 2 and its device housing 3 are arranged at the bottom of the restoration 1. Fig. 9 After the restoration is put into the mouth, Figure 7 The structural cross-section diagram after the straight line in is cut. Fig. 9 As shown, the restoration 1 is worn in the oral cavity and installed between the premolar and the second molar. Since the pressure sensor needs to sense the pressure of the restoration on the alveolar ridge 23 at the missing tooth, the pressure sensing module 6 is installed at the bottom of the movable restoration 1, that is, the top of the gum 22 and the alveolar ridge 23. Figure 7 As shown, the volume of the resin base 21 of the removable prosthesis for repairing a single posterior tooth can reach 20mm×20mm×1.5mm or more, and a GPS antenna with a larger area can be embedded in the base 21. The thickness of the resin base 21 is relatively fixed. Generally, the more missing teeth a patient has, the larger the area of ​​the resin base 21 of the removable denture, the larger the volume of the antenna, and the better the communication signal, providing better communication for the GPS positioning module. The patient may get lost due to memory loss and forget to bite his teeth hard to alarm. When there is no chewing and eating for a long time, the pressure receptor does not feel the pressure signal or the pressure is lower than the set threshold for a certain period of time, that is, the signal pressure transmitted by the pressure sensing module 6 to the main control module 4 is lower than the low pressure threshold, and the time interval between the two pressure signals or the duration of the no pressure signal is greater than the pre-set second time threshold, prompting the patient to encounter a critical situation, and the main control module 4 will promptly alarm and send the alarm information to the guardian's computer and / or mobile phone and other terminals. And the alarm information is sent every one minute until the patient recovers normal chewing pressure.
