Description

Technical Field

[0001] The invention relates to the technical field of occlusal plates, in particular to an occlusal plate for treating temporomandibular joint disorder and resetting the occlusal plate. Background Art

[0002] The symptoms of temporomandibular joint disorder include difficulty opening and closing the mouth, sometimes noise during opening and closing, and corresponding muscle pain in the temporomandibular joint. The causes of the disease are also varied, such as muscle dysfunction, continuous mental stress, minor joint trauma, joint overload, etc. The most common cause is anterior displacement of the articular disc. Doctors often use bite splints for conservative treatment of temporomandibular joint diseases caused by anterior displacement of the articular disc.

[0003] The bite splint has a specific occlusal surface shape and a certain thickness, which can provide a biological lever fulcrum to induce the mandible to enter the expected therapeutic jaw position. Specifically, the bite splint can adjust the abnormal position relationship between the mandible and the maxilla, and re-establish the mandibular closure type that conforms to the physiological state of the muscles. At the same time, by enhancing the mouth opening reflex, the jaw depressor muscles are activated and the jaw elevator muscles are relaxed, and the functional state of the masticatory muscles is improved to achieve the therapeutic purpose. In addition, the bite splint can directly or indirectly temporarily adjust and stabilize the position of the mandible and condyle in the articular fossa, reduce the pressure of the condyle on the posterior soft tissue of the joint, reduce the load on the joint, and reduce the intra-articular pressure, which is conducive to improving the internal environment of the temporomandibular joint and maintaining the stability of the joint position.

[0004] Most of the existing bite plates are made of flexible materials, which have the following problems during use. When patients wear them, the maxillary and mandibular dentitions often exert a strong force on them, causing them to be damaged, perforated or deformed, which will directly affect their functions and effects. Therefore, when re-examining, if the doctor finds that the bite plate is damaged, he will recommend replacing it with a new one. At the same time, if the patient bites the bite plate with a strong force, the joint will always be under load, which is not conducive to the early recovery of the temporomandibular joint. Since the existing bite plate does not have a prompt function for a strong bite force, it is necessary to design a bite plate for treating temporomandibular joint disorder and repositioning to solve the above problems. Summary of the invention

[0005] The present invention provides a occlusal plate for treating temporomandibular joint disorder and resetting the occlusal plate. The occlusal plate can remind a person whether the current occlusal force is appropriate by providing a receiving cavity capable of spraying a flowing substance according to the occlusal force, thereby avoiding a series of problems caused by a large occlusal force during wearing of the occlusal plate.

[0006] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0007] The present invention provides a occlusal plate for treating temporomandibular joint disorder, comprising a sleeve body and a accommodating cavity, wherein the sleeve body as a whole extends in a curve consistent with the dentition, the sleeve body comprises a palatal side wall and a buccal side wall arranged opposite to each other, and an occlusal body covering the horizontal coplanar ends of the palatal side wall and the buccal side wall, the palatal side wall, the buccal side wall and the occlusal body together form a accommodating groove which is open on at least one side opposite to the occlusal body, the accommodating cavity is used for accommodating a flowing substance and is opened inside the occlusal body, at least one micro-channel is opened on the side wall of the occlusal body on the same side as the palatal side wall to realize the connection between the accommodating cavity and the outside, when the occlusal force applied by the maxillary dentition and the mandibular dentition of the human body to the occlusal body is greater than a threshold value, the accommodating cavity generates a positive pressure based on deformation to cause the flowing substance stored inside to overflow.

[0008] Preferably, the microchannel vertically penetrates the side wall of the occlusal body.

[0009] Preferably, the microchannel extends in a curved manner inside the side wall of the engaging body.

[0010] Preferably, the interior of the accommodating cavity has a blocking body for limiting the deformation degree of the accommodating cavity.

[0011] Preferably, the blocking body is a ridge located at the center of the bottom of the accommodating cavity and extending vertically upward, and a through hole is opened at the lower position of the ridge.

[0012] Preferably, the sleeve body is made of transparent material.

[0013] Preferably, the flowable substance is in liquid or cream state.

[0014] Preferably, the flowable substance has a taste.

[0015] The beneficial effects of the present invention are as follows: by providing a accommodating cavity for accommodating flowing substances inside the occlusal body and by opening a micro-channel on the side wall of the occlusal body, when the maxillary dentition and the mandibular dentition apply a large bite force to the occlusal body, the flowing substances inside the accommodating cavity can be squeezed out, thereby alerting personnel that the current bite force is large.

[0016] By extending the microchannel inside the side wall, the microchannel can occupy a certain volume, thereby achieving buffering of the discharge process of the flowing material and preventing the flowing material from being discharged when the bite body is subjected to a small bite force.

[0017] By arranging a blocking body inside the accommodating cavity to limit the deformation of the accommodating cavity, it is avoided that the flowing material inside the accommodating cavity is discharged at one time, thereby saving the use of the flowing material.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0031] In order to enable those skilled in the art to understand the inventive point of the present invention, the prior art part involved in the present invention is first described, and reference is made to Figure 1 and Figure 2 The existing bite plate is a sleeve body 1 as a whole, which is directly sleeved on the maxillary dentition or the mandibular dentition when used, so that the maxillary dentition and the mandibular dentition have a suitable occlusal angle, thereby adjusting the abnormal position relationship of the mandible to the maxilla, re-establishing the mandibular closure type that conforms to the muscle physiological state, enhancing the mouth opening reflex, making the depressor muscles active and the elevator muscles relaxed, and directly or indirectly temporarily adjusting and stabilizing the position of the mandible and condyle in the articular fossa, reducing the pressure of the condyle on the posterior soft tissue of the joint, reducing the load on the joint, and reducing the intra-articular pressure, which is beneficial to improving the internal environment of the temporomandibular joint and maintaining the stability of the joint position. The sleeve body 1 constituting the bite plate mainly includes a palatal wall 4, a buccal wall 2 and an occlusal body 3, wherein the palatal wall 4 and the buccal wall 2 are arranged relatively, and the occlusal body 3 covers the horizontal coplanar ends of the palatal wall 4 and the buccal wall 2 (i.e., the upper end face or the lower end face, attached Figure 1 The upper end surfaces of the palatal wall 4 and the buccal wall 2 are in the middle) so that the palatal wall 4, the buccal wall 2 and the occlusal body 3 are connected to form a whole, and the palatal wall 4, the buccal wall 2 and the occlusal body 3 are surrounded to form a receiving groove 5 which is open on at least one side opposite to the occlusal body 3. When worn, the maxillary dentition or the mandibular dentition is placed in the receiving groove 5, and the palatal wall 4 and the buccal wall 2 occlude the dentition to achieve wearing. It should be noted that the palatal wall 4 is the side wall close to the tongue when the sleeve body 1 is worn on the dentition, and the buccal wall 2 is the side wall close to the cheek when worn on the dentition, and the receiving groove 5 is open on at least one side opposite to the occlusal body 3, and is attached Figure 2 It is understood that at least the lower opening is provided. Of course, it may be not only the lower opening, but also openings at both ends of the sleeve 1 in the extension direction, that is, the length extension ends of the palatal wall 4 and the buccal wall 2 are not connected to form an opening. This method can also realize the covering of the dentition by the accommodating groove 5. The above is an introduction of the prior art to the present invention.

[0032] The problem with the existing bite plate during use is that when the maxillary dentition and the mandibular dentition are closed, the occlusal body 3 will be bitten. If the bite force is too large for a long time, the sharp position of the dentition will cause the occlusal body 3 to be damaged, and the limiting effect on the bite position will be lost. At the same time, if the bite force is large for a long time, the joint will always be under load without relaxation time, which is not conducive to the patient's early recovery. Based on this problem, the present invention overcomes it through improvements in the following ways.

[0033] refer to Figure 3 and Figure 4The main improvement of the present invention is that a accommodating cavity 6 for accommodating a flowing substance is provided inside the existing occlusal body 3, and a micro-channel 7 is provided on the side wall of the accommodating cavity 6 facing the inside of the oral cavity (the side wall on the same side of the occlusal body 3 and the palatal side wall 4), so that the accommodating cavity 6 is connected with the outside. Since the size of the micro-channel 7 is small, when the occlusal body 3 is not occluded by the maxillary dentition and the mandibular dentition, the flowing substance can be stably inside the accommodating cavity 6 (the accommodating cavity 6 is connected with the outside only through the micro-channel 7, so under the action of gas pressure, the flowing substance will not overflow along the micro-channel 7). When the maxillary dentition and the mandibular dentition are in occlusal state, and the occlusal force causes the occlusal body 3 to deform, the accommodating cavity 6 deforms and collapses. The interior of the accommodating cavity 6 generates positive pressure due to the reduction in volume, prompting the internal flowing material to be discharged through the microchannel 7. Since the microchannel 7 is arranged near the palatal wall 4, the flowing material discharged from the microchannel 7 directly enters the oral cavity. The human oral cavity judges that the flowing material is discharged based on touch or taste, thereby alerting the wearer that the current bite force is large. When the human body wears the bite plate, the ideal state is that the maxillary dentition and the mandibular dentition are in a relaxed occlusal state, that is, the maxillary dentition is naturally The jaw joint is supported on the occlusal body 3, and is in a relaxed state. It does not exert downward force on the maxillary dentition. In this state, the occlusal force on the jaw joint 3 is basically entirely from the gravity of the upper jaw and the maxillary dentition. This gravity is relatively small and can be basically ignored. 0N is taken as an example here. When the human body is chewing, the bite force is generally around 100-200N (depending on the body shape, age, etc.). However, it is obvious that the mandibular joint of the human body is already under load when chewing food. Therefore, in order to better make the load on the mandibular joint of the human body as small as possible when wearing the occlusal plate, and to avoid the occlusion of the occlusal plate When the body 3 is slightly subjected to the bite force, it begins to deform and causes the flowing material to be discharged. The bite force threshold (the critical state force that can make the flowing material just spray out or just not spray out) should be considered to be set between 0N and 100N. For example, 50N is set as the bite force threshold. When the bite force value exceeds 50N, the flowing material sprays out. When the bite force value is less than 50N, the flowing material does not flow out. Of course, the bite force threshold of 50N is only used as an example here. The specific bite force threshold still needs to be set by the clinician according to the patient's own situation. The size adjustment of the bite force threshold can be achieved by changing the material, structure or shape of the bite body 3.

[0034] It should be noted that the above-mentioned flowable substance can be in liquid or cream state, and preferably should have a taste, such as sour, sweet, bitter, spicy, salty and the like. Considering that children generally like sweet taste and have poor self-control, it is not appropriate to use sweet flowable substances when the patient is a child. In this case, the flowable substance should have sour, bitter, salty and other tastes that children do not like, so that they will produce a conditioned reflex and will not bite the occlusal plate with force. It should be further noted that the number of the above-mentioned accommodating cavities and their size relative to the occlusal body are not specifically limited.

[0035] Further, if Figure 4 The microchannel 7 can be arranged to vertically penetrate the side wall of the occlusal body 3 (the side close to the palatal side wall 4), such as Figure 5 and Figure 6 The microchannel 7 can also be arranged to bend and extend inside the side wall of the occlusal body 3, preferably, it is arranged to be able to bend and extend inside the occlusal body 3, such as Figure 6 In the figure, the microchannel 7 extends a certain length from its input end 701 inside the side wall of the occlusal body 3 (the side close to the palatal side wall 4) and then connects to the outside through the output end 702, so that when the occlusal body 3 is subjected to a smaller bite force and produces a smaller deformation, the flowing material inside the accommodating cavity 6 will first enter the microchannel 7 with a certain length and will not be directly discharged, thereby avoiding the discharge of flowing material from the occlusal body 3 when the occlusal body 3 is subjected to a smaller bite force. Obviously, by changing the shape and size of the microchannel 7, the bite force threshold can also be adjusted, that is, for the occlusal body 3 of the same material and shape, the state of the microchannel 7 bending and extending inside the occlusal body 3 requires a larger bite force to achieve the discharge of the flowing material than the state of the microchannel 7 directly and vertically penetrating the side wall of the occlusal body 3. It should be further explained that the shape of the bending and extending microchannel 7 can be serpentine, bent or spiral, which is not further limited here, and the number of microchannels 7 can also be set to more than one.

[0036] Furthermore, in order to prevent the accommodating chamber 6 from deforming significantly when subjected to a larger bite force, thereby causing all the flowing material inside the accommodating chamber 6 to be discharged, a blocking body is also provided inside the accommodating chamber 6 to prevent the accommodating chamber 6 from deforming significantly at once, causing all the flowing material to be discharged. The blocking body can be a block placed inside the accommodating chamber 6 (which can move slightly inside the accommodating chamber 6 and has an unfixed position), or it can be a block fixed relative to the inside of the accommodating chamber 6.

[0037] Specifically, refer to Figure 7 , Figure 8 and Fig. 9The blocking body as a relatively fixed block may be a ridge 8 located at the center of the bottom of the accommodating cavity 6 and extending vertically upward. Being arranged at the center can better ensure the stability of the limited deformation, such as Fig. 9 In the embodiment, when the occlusal body 3 is occluded by the maxillary dentition and the mandibular dentition, the upper end wall 301 and the lower end wall 302 of the accommodating chamber 6 will move toward the middle of the accommodating chamber 6 (in the direction of approaching each other), thereby causing the accommodating chamber 6 to deform. If the deformation is large, a large amount of the flowing material inside the accommodating chamber 6 will be discharged at one time. By providing the ridge 8, the upper end wall 301 and the lower end wall 302 can be blocked from approaching each other during the deformation of the accommodating chamber 6, thereby avoiding a large deformation of the accommodating chamber 6, which causes the flowing material to be completely discharged. It should be further explained here that, considering the gravity of the flowing material, when Figure 7 , Figure 8 and Fig. 9 When the sleeve 1 is worn for the mandibular dentition, the microchannel 7 should be opened closer to the lower end wall 302 in the vertical direction on the side wall of the accommodating cavity 6 (close to the palate) to prevent part of the flowing material from accumulating inside the accommodating cavity 6. If the sleeve 1 is worn on the maxillary dentition, the microchannel 7 should be opened closer to the lower end wall 302 in the vertical direction. Fig. 9 The position of the middle and upper end wall 301 prevents the flowing material from being lower than the input port of the microchannel 7 due to gravity, resulting in failure to discharge.

[0038] Furthermore, the ridge 8 provided above divides the accommodating cavity 6 into two parts ( Fig. 9 Since the microchannel 7 is arranged near (the side of the palatal wall 4), in order to allow the two parts of the flowing materials separated inside the accommodating cavity 6 to be discharged smoothly, a through hole 801 is also opened at the lower position of the ridge 8 to facilitate the mutual flow of the flowing materials on both sides of the accommodating cavity 6.

[0039] Furthermore, in order to facilitate observation of the remaining flow material in the accommodating chamber 6, the sleeve 1 is at least partially transparent. By setting the partially transparent state, it is possible to facilitate observation of the remaining flow material in the accommodating chamber 6. Of course, considering the difficulty of processing, the sleeve 1 can also be set to be transparent as a whole. The overall transparent state is not only beautiful and has low processing difficulty, but also makes it easier to observe the remaining flow material in the accommodating chamber 6. When the flow material in the accommodating chamber 6 is insufficient, the flow material can be injected into the microchannel 7 through a syringe with a needle.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
