Description

Technical Field

[0001] The utility model relates to the field of medical instruments, more specifically to the field of oral appliances, and in particular to a dental instrument for stopping snoring. Background Art

[0002] Snoring is a common sleeping phenomenon. Up to now, most people still think that snoring is commonplace and do not take it seriously. Some people even regard snoring as a sign of good sleep. In fact, snoring is the enemy of health. Snoring can lead to daytime sleepiness, fatigue, inattention, headache, decreased work ability, etc. Severe snoring is often accompanied by sleep apnea syndrome. Snoring can even cause repeated pauses in breathing during sleep, resulting in severe hypoxia of the brain and blood, forming hypoxemia, and inducing high blood pressure, cerebrocardia, arrhythmia, myocardial infarction, angina pectoris, etc., seriously affecting the patient's health.

[0003] There are many reasons for snoring, most of which are caused by airway obstruction. The nasal cavity and oral cavity are connected to the airway. When a person is asleep, the airway tissue may collapse due to muscle relaxation, mandibular retraction, and tongue falling back, causing airway obstruction. Especially for obese people, their airways are usually narrower, which makes them more prone to airway obstruction. One way to open the airway is to stretch the mandible forward to increase the muscle tension of the throat, tongue and soft palate, thereby opening the airway that collapses due to muscle relaxation during sleep. Therefore, the way to stop snoring caused by this reason is to pull the mandible forward to the ideal position to open the airway.

[0004] In recent years, in the field of orthodontics, invisible shell-shaped dental appliances have become increasingly popular because of their advantages of being beautiful and convenient to wear. Various orthodontic manufacturers have also tried to combine anti-snoring devices with invisible shell-shaped dental appliances. A mounting portion is provided in the area of ​​the upper front teeth of the shell-shaped dental appliance, and a rigid connector is provided in the area of ​​the lower back teeth of the shell-shaped dental appliance. When worn, the connector is connected to the mounting portion to keep the lower jaw in a forward position, thereby opening the airway to suppress snoring. However, because different patients require different degrees of airway opening to suppress snoring, the currently available snoring suppressors can suppress snoring, but they are usually designed and customized according to different patients. Even for the same patient, the customized mounting parts and connectors usually only consider the best airway opening degree to suppress snoring, that is, there is only one airway opening degree, which cannot be adjusted. If adjustment is required to satisfy both airway opening to suppress snoring and comfortable wearing, several sets of snoring suppressors and their accessories (such as mounting parts and connectors) can only be designed and customized, and then the snoring suppressors that suit them can be tried out. This will result in a waste of materials and cannot be mass-produced.

[0005] Therefore, it is necessary to provide a snoring control device that can meet different needs for suppressing snoring and improve the comfort of patients, and can also provide standardized snoring control device accessories to save production costs. Utility Model Content

[0006] The technical problem solved by the utility model is to overcome the defects of the prior art and provide a dental device for stopping snoring, which can not only meet different needs for suppressing snoring, but also facilitate production and save production costs.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A dental device for stopping snoring, comprising: a maxillary shell-shaped dental device for accommodating a patient's maxillary dentition and a mandibular shell-shaped dental device for accommodating a patient's mandible; a fixing portion arranged on the buccal side of the maxillary shell-shaped dental device near the front teeth, and a connecting rod with one end connected to the buccal side of the mandibular shell-shaped dental device near the posterior teeth, or a fixing portion arranged on the buccal side of the mandibular shell-shaped dental device near the posterior teeth, and a connecting rod with one end connected to the buccal side of the maxillary shell-shaped dental device near the front teeth; wherein the fixing portion comprises a boss, the boss protruding toward the distal teeth, and the other end of the connecting rod is provided with a plurality of mounting holes at intervals along its long axis direction, the plurality of mounting holes can be respectively mounted in cooperation with the boss to enable the mandible to produce different sagittal movement amounts, and the patient's mandible can be maintained at different forward positions.

[0009] The design of multiple mounting holes can guide the mandible forward and open the patient's airway to varying degrees, and is suitable for different patients because different patients have different requirements for the degree of opening the airway; it can also be suitable for the same patient. When wearing the dental device for stopping snoring, the patient can choose a mounting hole that suits him / her for installation, that is, he / she can try out a comfortable mounting position within the range that can open the airway and suppress snoring. In this way, the patient's willingness to wear the dental device for stopping snoring is improved, which is conducive to achieving the expected goal of suppressing snoring. This also has a high application value in production practice. During design and production, the connecting rod is designed to have a structure containing multiple mounting holes. At this time, the standardized production of the connecting rod can be achieved, and the fixing part can also be set to a standard position (integrally formed or installed separately after separate processing), which brings convenience to production. In clinical applications, according to the needs of different patients, clinicians can guide patients to install the appropriate mounting holes on the fixing part according to the clinical needs of the patients.

[0010] Preferably, the fixing part and the mounting hole are elastically matched, and when the fixing part and the mounting hole are matched and installed, the fixing part or the mounting hole is elastically deformed so that the fixing part can be accommodated in the mounting hole. The design of elastic matching facilitates the matching installation of the fixing part and the mounting hole, and after the mounting hole sleeve is installed on the fixing part, the fixing part or the mounting hole has a tendency to restore the original shape, so that the installation matching of the mounting hole and the fixing part is more secure and not easy to separate from the fixing part.

[0011] Preferably, the outer contour size of the boss is smaller than the inner contour size of the mounting hole. Such a structural design facilitates the installation of the mounting hole.

[0012] Preferably, the free end of the protrusion is provided with a mounting cap extending in all directions and having a smooth edge, and the outer contour size of the mounting cap is larger than the outer contour size of the protrusion. Such a structural design enables the mounting hole sleeve to be better confined between the buccal side of the shell-shaped dental instrument where the protrusion is located and the mounting cap after being installed on the protrusion, and is not easy to fall off.

[0013] Preferably, the plurality of mounting holes are arranged at even intervals.

[0014] Preferably, the spacing distance between the plurality of mounting holes ranges from 1 mm to 5 mm.

[0015] Preferably, the plurality of mounting holes are arranged at non-uniform intervals, and the interval distance gradually increases in a direction from the connecting rod adjacent to the fixing portion to a direction away from the fixing portion.

[0016] Preferably, a communicating channel is provided between the plurality of mounting holes, and the inner contour dimension of the channel is smaller than the inner contour dimension of the mounting hole and the outer contour dimension of the boss. Such a structural design can facilitate sliding switching between different mounting holes without the need to separate the mounting hole and the boss before installation each time a replacement is made.

[0017] Preferably, the inner side wall of the channel is elastic so that the boss can pass through the channel and be accommodated in the mounting hole. Such a structural design allows the inner side wall of the channel to be elastically deformed when the boss moves in the channel, so that the boss can smoothly pass through the channel and be accommodated in the mounting hole.

[0018] Preferably, the fixing portion further comprises a connecting cap, which is separately provided from the boss, and after the boss is received in the mounting hole, the connecting cap is connected to the free end of the boss by threaded connection, clamping or bonding. Such a structural design enables the mounting hole to be securely received between the connecting cap and the buccal side surface covered by the boss, and is not easily separated.

[0019] Preferably, the connection cap is connected to the boss by threaded connection, an end of the connection cap adjacent to the boss is concavely provided with an internal thread, and an outer side wall of the boss is provided with an external thread.

[0020] Preferably, the connecting cap further comprises a connecting column, which is arranged at one end of the connecting cap adjacent to the convex column, and one end of the connecting column away from the connecting cap is connected to the free end of the convex column by means of threaded connection or clamping.

[0021] Preferably, the boss and the connecting column are connected by snapping; a hollow structure is concavely provided at the free end of the boss, the hollow structure includes a guide channel and a accommodating cavity adjacent to the guide channel, the connecting column includes a clamping portion and a rod portion adjacent to the clamping portion, wherein the clamping portion is elastically compressed when passing through the guide channel, the clamping portion returns to its original shape after entering the accommodating cavity and is constrained in the accommodating cavity in a removable manner, and the rod portion is accommodated in the guide channel.

[0022] Preferably, the fixing part and the shell-shaped dental instrument are separate structures, and the fixing part is bonded to the shell-shaped dental instrument by bonding. Such a structural design can mass-produce standard fixing parts that match the mounting holes of the connecting rod without personalized customization, which can reduce production costs and improve production efficiency.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the various embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in each embodiment of the utility model, many technical details are proposed in order to enable readers to better understand the utility model. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection of the utility model can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model.

[0032] Directional terms such as "upper", "lower", "left", and "right" used in the description herein are directions in the drawings and do not refer to special limitations. Unless otherwise specified and limited, the term "connection" in this article should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium.

[0033] The "posterior tooth area" mentioned in each embodiment of the present invention is defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38, including premolars and molars, which are teeth 4-8 in the FDI marking method, and teeth 1-3 in the anterior tooth area in the FDI marking method. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0034] As can be seen from the background technology, although the existing snoring control devices can suppress snoring, the accessories of the snoring control devices (such as mounting parts and connectors) are usually designed and customized according to different patients; even for the same patient, the customized mounting parts and connectors usually only consider the best airway opening degree to suppress snoring, that is, there is only one airway opening degree, which cannot be adjusted. If adjustment is required to satisfy both the airway opening and snoring suppression and comfortable wearing, several sets of snoring control device accessories (such as mounting parts and connectors) can be designed and customized, and then the snoring control device suitable for oneself can be tried out; this will cause waste of materials and cannot be mass-produced.

[0035] Based on this, the inventor proposes a dental device for stopping snoring, which can not only meet different needs for suppressing snoring, but also facilitate production and save production costs. The dental device for stopping snoring of the present application includes: a maxillary shell-shaped dental device and a mandibular shell-shaped dental device for accommodating the patient's dentition; a fixing portion arranged on the buccal side of the maxillary shell-shaped dental device near the front teeth, and a connecting rod connected at one end to the buccal side of the mandibular shell-shaped dental device near the posterior teeth, or, a fixing portion arranged on the buccal side of the maxillary shell-shaped dental device near the posterior teeth, and a connecting rod connected at one end to the buccal side of the mandibular shell-shaped dental device near the front teeth; wherein the fixing portion includes a boss, the boss protrudes toward the distal teeth, and the other end of the connecting rod is provided with a plurality of mounting holes spaced along its long axis direction, and the plurality of mounting holes can be respectively mounted in cooperation with the boss to enable the mandible to produce different sagittal movement amounts, and the patient's mandible can be maintained at different forward positions.

[0036] Please see Figures 1 to 3 As shown, the dental device 100 for stopping snoring of the present application comprises an upper shell-shaped dental device 1 for accommodating the upper and lower dentitions of a patient, a lower shell-shaped dental device 2, a fixing portion 3 and a connecting rod 4. The upper shell-shaped dental device 1 comprises a plurality of cavities arranged in a U shape for accommodating a plurality of teeth, and the geometry of the cavities matches the upper dentition; the lower shell-shaped dental device 2 comprises a plurality of cavities arranged in a U shape for accommodating a plurality of teeth, and the geometry of the cavities matches the lower dentition. The fixing part 3 is arranged on the buccal side of the maxillary shell-shaped dental instrument 1 near the front teeth, and one end of the connecting rod 4 is movably connected to the buccal side of the mandibular shell-shaped dental instrument 2 near the posterior teeth, or the fixing part 3 is arranged on the buccal side of the mandibular shell-shaped dental instrument 1 near the posterior teeth, and one end of the connecting rod 4 is movably connected to the buccal side of the maxillary shell-shaped dental instrument 2 near the front teeth; usually, the fixing part 3 is arranged on both sides of the buccal side of the maxillary shell-shaped dental instrument 1, and the connecting rod 4 is arranged on both sides of the buccal side of the mandibular shell-shaped dental instrument 2; further, the fixing part 3 and the connecting rod 4 are symmetrically arranged on both sides of the buccal side of the maxillary shell-shaped dental instrument 1 and the mandibular shell-shaped dental instrument 2, respectively, so that the left and right sides of the patient's mandible are subjected to equal sagittal forward force, thereby improving the patient's comfort. The fixing part 3 includes a convex column 31, which protrudes toward the distal tooth direction. The convex column 31 can be formed integrally with the maxillary shell-shaped dental instrument 1, or the convex column 31 can be manufactured separately and then installed on the buccal side of the maxillary shell-shaped dental instrument 1 by bonding or welding. The other end of the connecting rod 4 is provided with a plurality of mounting holes 41 spaced along its long axis direction. The plurality of mounting holes 41 can be respectively installed in cooperation with the convex column 31 on the same side, so that the mandible produces different sagittal movement amounts, and the patient's mandible can be kept at different front positions. Figure 1 For example, Figure 1When the fixing part 3 is installed and fixed to the mounting hole 41 on the connecting rod 4 adjacent to the posterior teeth, with the position of the fixing part 3 unchanged, the distance the mandible is guided forward is the largest, the force applied to the patient to guide the mandible forward is also the largest, the effect of opening the airway is also the best, but the patient's comfort is the worst.

[0037] The design of multiple mounting holes 41 can guide the mandible forward and open the patient's airway to varying degrees, and is suitable for different patients because different patients have different requirements for the degree of airway opening. It can also be suitable for the same patient. When wearing the dental device 100 for stopping snoring, the patient can choose a mounting hole 41 that suits him / her for installation, that is, a comfortable mounting position can be tried out within the range that can open the airway and suppress snoring. In this way, the patient's willingness to wear the dental device 100 for stopping snoring is improved, which is conducive to achieving the desired goal of suppressing snoring. This has a high application value in production practice. For example, different patients have different requirements for the degree of airway opening. In traditional design, it is necessary to customize the installation position of the fixing part 3 and the connecting rod 4 according to the actual clinical situation of the patient, so that the fixing part 3 and its installation position, as well as the length of the connecting rod 4, can meet the patient's personalized needs for opening the airway after cooperating with the fixing part 3, such as customizing the fixing part 3 and its setting and installation position, and the length of the connecting rod 4, etc., so it is impossible to achieve mass production and the production cost is high. The inventor designs the connecting rod 4 to include a structure of multiple mounting holes 41. At this time, the standardized production of the connecting rod 4 can be achieved, and the fixing part 3 can also be set to a standard position (integrally formed or separately processed and installed separately), which brings convenience to production. In clinical applications, according to the needs of different patients, clinicians can guide patients to install appropriate mounting holes 41 on the fixing part 3 according to the clinical needs of the patients. For the same patient, it also has a high practical value. The patient suppresses snoring by opening the airway. The fixing part 3 and the connecting rod 4 cooperate with each other. There are connection cooperation modes with the best opening effect, and there are connection cooperation modes that can meet the needs but are not necessarily the best opening effect. However, often the best opening effect requires the mandible to be guided forward sagittally to the maximum distance, and the patient often has a very poor sense of comfort, especially when the dental device 100 for stopping snoring is first worn. The strong discomfort caused by the sudden application of the force that can guide the mandible forward to the maximum distance may cause the patient to give up wearing it, thereby affecting the treatment effect. When wearing the dental device 100 for stopping snoring described in the present application, the patient can choose the degree to which the mandible is guided forward step by step, such as first selecting a mounting hole 41 away from the back teeth, and after adapting to the current state, performing a trial installation of the next mounting hole 41; or when wearing it for the first time, multiple mounting holes 41 can be tried, so as to select a mounting hole 41 that can both suppress snoring and be comfortable to wear. Therefore, the design of the plurality of mounting holes 41 enhances the patient's willingness to wear the device, thereby facilitating the therapeutic purpose of suppressing snoring.

[0038] When wearing the dental device 100 for stopping snoring of the present application, the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2 can be worn separately first; wherein, if the boss 31 and the maxillary shell-shaped dental device 1 are manufactured separately, the boss 31 can be installed outside the mouth first, and then the maxillary shell-shaped dental device 1 can be worn on the patient's maxillary dentition; since the connecting rod 4 is arranged at the position of the mandibular shell-shaped dental device 2 close to the posterior teeth, and the space in the oral cavity is relatively small, therefore, for the convenience of operation, the connecting rod 4 can also be connected to the mandibular shell-shaped dental device 2 outside the mouth first, and then the mandibular shell-shaped dental device 2 can be worn on the patient's mandibular dentition; then, the mounting hole 41 that meets the patient's needs is installed on the boss 31, and the patient's mandible is moved forward sagittally to a preset position, that is, the patient's mandible is moved forward sagittally to a position that can open its airway, and the patient's mandible is maintained and stabilized at the preset position, thereby suppressing the patient's snoring. Alternatively, the dental device 100 for stopping snoring may be installed and assembled outside the mouth, that is, if the boss 31 and the maxillary shell-shaped dental device 1 are manufactured separately, the boss 31 may be installed outside the mouth first; the connecting rod 4 may be arranged at a position of the mandibular shell-shaped dental device 2 close to the posterior teeth; and then the mounting hole 41 that meets the needs of the patient may be selected and installed on the boss 31; finally, the installed dental device 100 for stopping snoring may be worn in the patient's mouth.

[0039] In some embodiments, the fixing portion 3 and the mounting hole 41 are elastically matched, and are usually designed so that one of the fixing portion 3 and the mounting hole 41 is elastic. When the fixing portion 3 and the mounting hole 41 are matched and installed, one of the fixing portion 3 and the mounting hole 41 can undergo elastic deformation, so that the mounting hole 41 can be mounted on the fixing portion 3, and after installation, the elastically deformed fixing portion 3 or the mounting hole 41 has a tendency to restore its original shape, so that the installation fit between the mounting hole 41 and the fixing portion 3 is more secure and not easy to detach from the fixing portion 3.

[0040] In some embodiments, please refer to Figure 1 and Figure 5As shown, the outer contour dimension D1 of the boss 31 is smaller than the inner contour dimension D of the mounting hole 41. Such a design facilitates the installation of the mounting hole 41. Moreover, such a dimensional relationship will not cause the mounting hole 41 and the boss 31 to separate, because after the mounting hole 41 and the boss 31 are installed, the patient's mandible is subjected to a sagittal forward force F1. Since the force is mutual, the connecting rod 4 will be subjected to a sagittal backward force F2. After the mounting hole 41 and the boss 31 are installed, the inner side wall of the mounting hole 41 close to the front teeth has a backward force F2 relative to the boss 31. Under the action of the force, the inner side wall of the mounting hole 41 close to the front teeth will abut against the side of the boss 31 close to the front teeth, and the mounting hole 41 will not fall off the boss 31, which is safer and more reliable.

[0041] In some embodiments, see Figure 4 As shown, the free end 311 of the boss 31 is provided with a mounting cap 32 extending in all directions and having a rounded edge, and the outer contour dimension D3 of the mounting cap 32 is larger than the outer contour dimension D1 of the boss 31. Specifically, the mounting cap 32 has a rounded outer edge and is in a "button" shape, so that after the mounting hole 41 is mounted on the boss 31, it can be better confined between the buccal side of the shell-shaped dental device where the boss 31 is located and the mounting cap 32, and is not easy to fall off; moreover, the outer edge of the mounting cap 32 is smooth and round, and it is more comfortable to wear.

[0042] In some embodiments, the plurality of mounting holes 41 are evenly spaced. Figure 5 As shown, Figure 5 As shown in the figure, three mounting holes 41 are evenly spaced, that is, the spacing distance between two adjacent mounting holes 41 is L. Preferably, the spacing distance L between the plurality of mounting holes 41 ranges from 1mm to 5mm. Furthermore, the spacing distance L between adjacent mounting holes 41 preferably ranges from 2mm to 3mm. After a large number of experiments, the inventors designed a spacing distance range of 1mm to 5mm. On the one hand, such a spacing distance range design allows most patients to switch between adjacent mounting holes 41 to find a suitable installation distance for their needs. In this way, there is no need to customize the connecting rod 4 for each patient, and to individually design the fixing part 3 and the installation position of the fixing part 3, which facilitates the standardized production of the connecting rod 4 and the fixing part 3; on the other hand, such a spacing distance range design can satisfy most patients to try on and find a preset position that suits them, further improving the patient's comfort and willingness to wear, thereby improving the treatment effect and efficiency.

[0043] In other embodiments, the plurality of mounting holes 41 are arranged at non-uniform intervals, and the interval distance gradually increases from the direction where the connecting rod 4 is adjacent to the fixing portion 3 to the direction away from the fixing portion 3. Figure 6 As shown, there are three mounting holes 41 on the connecting rod 4, wherein the spacing distance L1 between the mounting hole 411 and the mounting hole 412 is smaller than the spacing distance L2 between the mounting hole 412 and the mounting hole 413. With such a gradually increasing spacing design, the optional mounting holes 41 can meet a wider range of applications and meet diverse needs (including different distance requirements for guiding the mandible forward for different patients, or the same patient's need to choose between comfort and the target value of the distance for guiding the mandible forward), and can also ensure the mechanical strength of the connecting rod 4. For example, in order to apply a wider distance for guiding the mandible forward, it is necessary to design more mounting holes 41, for example, four or five. However, at this time, the mechanical strength of the connecting rod 4 will be reduced due to the provision of multiple mounting holes 41, thereby reducing the strength of the connecting rod 4 when maintaining the mandible forward position, which is not conducive to maintaining the patient's mandible in a position that meets clinical needs.

[0044] In some embodiments, see Figure 7 As shown, a communicating channel 42 is provided between the plurality of mounting holes 41, and the inner contour dimension D4 of the channel 42 is smaller than the inner contour dimension D2 of the mounting hole 41 and the outer contour dimension D1 of the boss 31. With such a design, it is convenient to slide and switch between different mounting holes 41. When replacing the mounting hole 41, one end of the connecting rod 4 provided with the mounting hole 41 can be pulled in a direction away from the other end of the connecting rod 4, and the boss 31 can be moved out of one of the mounting holes 41 and enter the channel 42 connected thereto, and then moved into another adjacent mounting hole 41 through the channel 42 and accommodated in the mounting hole 41, so as to complete the matching installation of the boss 31 and the mounting hole 41. Preferably, the inner wall of the channel 42 is elastic, or the outer wall of the boss 31 is elastic, so that when the boss 31 moves in the channel 42, the inner wall of the channel 42 or the outer wall of the boss 31 is elastically deformed, so that the boss 31 is accommodated in the mounting hole 41 after passing through the channel 42, that is, the boss 31 is allowed to move out of the current mounting hole 41 and enter another adjacent mounting hole 41 through the channel 42 connected thereto.

[0045] In some embodiments, see Figure 8As shown, in order to make the mounting hole 41 more securely mounted after the boss 31, the inventors also designed a connecting cap 33 as a component structure of the fixing portion 3. The connecting cap 33 and the boss 31 are separately arranged. Specifically, when the boss 31 is accommodated in the mounting hole 41, the connecting cap 33 is connected to the free end 311 of the boss 31 by threaded connection, clamping or bonding. After installation, the whole is as shown in FIG. Figure 8 As shown, in this way, the mounting hole 41 can be securely accommodated between the connecting cap 33 and the buccal side surface covered by the protrusion 31 and is not easy to fall off.

[0046] In some embodiments, see Fig. 9 and Fig.10 As shown, the connection cap 33 is connected to the boss 31 by a threaded connection. Specifically, the connection cap 33 is concavely provided with an internal thread at one end adjacent to the boss 31, and the outer wall of the boss 31 is provided with an external thread. When the mounting hole 41 is mounted on the boss 31, the external thread on the boss 31 passes through the mounting hole 41, and the operator (clinician or patient) installs the connection cap 33 on the boss 31 by threaded connection. In this way, the mounting hole 41 can be securely accommodated between the connection cap 33 and the buccal side covered by the boss 31, and is not easy to be separated. In order to facilitate the operation during the threaded connection, the applicant has also designed an auxiliary installation groove 30 at the top of the outer edge of the connection cap 33 in some embodiments. For example, the groove 30 can accommodate a flat screwdriver. When installing, the flat screwdriver is inserted into the groove 30 and rotated along the thread direction to install the connection cap 33.

[0047] In some embodiments, the connecting cap 33 may further include a connecting column 34, which is disposed at one end of the connecting cap 33 adjacent to the convex column 31. The connecting column 34 may be integrally formed with the connecting cap 33, or may be separately manufactured and then bonded together. The end of the connecting column 34 away from the connecting cap 33 is connected to the free end 311 of the convex column 31 by a threaded connection or a snap-on connection.

[0048] In some embodiments, the boss 31 and the connecting column 34 are connected by threads. Fig.11 As shown, the connecting column 34 is provided with an external thread, the inner wall of the boss 31 is a hollow structure 35, and the inner wall of the hollow structure 35 is provided with an internal thread. After the mounting hole 41 is mounted on the boss 31, the operator (clinician or patient) installs the connecting cap 33 on the boss 31 through a threaded connection.

[0049] In some embodiments, the boss 31 and the connecting post 34 are connected by a snap-fitting manner. Figures 12 to 15As shown, the free end 311 of the convex column 31 is concavely provided with a hollow structure 35, and the hollow structure 35 includes a guide channel 351 and a receiving cavity 352 adjacent to the guide channel 351. The connecting column 34 includes a clamping portion 341 and a rod portion 342 adjacent to the clamping portion 341. When installed, the clamping portion 341 is elastically compressed when passing through the guide channel 351, so that the clamping portion 341 can enter the receiving cavity 352 through the guide channel 351. When the clamping portion 341 enters the receiving cavity The cavity 352 then returns to its shape before being elastically compressed, and is clamped by one end of the accommodating cavity 352 connected to the guide channel 351, and the rod portion 342 is accommodated in the guide channel 351, and the end of the clamping portion 341 away from the rod portion 342 abuts against the limiting structure 36, wherein the limiting structure 36 can be the bottom wall of the hollow structure 35 (not shown), or a bottom plate arranged in the hollow structure 35, which is used to abut against the end of the clamping portion 341 away from the rod portion 342 to install the connecting column 34 in place. Such a structural design can make the clamping part 341 limited in both the insertion direction X and the extraction direction because of the abutment of the limiting structure 36 when the clamping part 341 is accommodated in the accommodating cavity 352, and because of the clamping of the end of the guide channel 351 connected to the accommodating cavity 352 in the extraction direction (i.e., the direction opposite to the insertion direction X), so that the clamping part 341 is limited in both the insertion direction X and the extraction direction, making the installation of the connecting cap 33 and the boss 31 more reliable. When disassembling, the connecting cap 33 can be easily separated from the boss 31 by simply pulling in the extraction direction; the entire installation and disassembly process is simple and quick to operate.

[0050] Specifically, the clamping portion 341 includes a first guide portion 343, a second guide portion 344 and a release groove 345, wherein the first guide portion 343 is arranged adjacent to the free end of the clamping portion 341, and the second guide portion 344 is arranged adjacent to the first guide portion 343; the release groove 345 spans the clamping portion 341 to divide the clamping portion 341 into two parts, and one end of the release groove 345 adjacent to the free end of the clamping portion 341 is open to provide a release space for the clamping portion 341 to be compressed and elastically deformed when being inserted into or pulled out of the guide channel 351. The depth H of the release groove 345 along the axial direction is greater than or equal to the length L3 of the clamping portion 341 along the axial direction. Such a structural design helps the release groove 345 to better meet the release space required for the elastic deformation of the clamping portion 341 when being inserted into or pulled out of the guide channel 351, so as to ensure that the clamping portion 341 can be inserted into or pulled out of the guide channel 351.

[0051] In some embodiments, the fixing portion 3 and the shell-shaped dental instrument in which it is located are separate structures, and the fixing portion 3 is bonded to the shell-shaped dental instrument by bonding. Specifically, the fixing portion 3 and the shell-shaped dental instrument in which it is located (the maxillary shell-shaped dental instrument 1 or the mandibular shell-shaped dental instrument 2) can be manufactured separately and then bonded and fixed. With such a design, standard parts of the fixing portion 3 that match the mounting hole 41 of the connecting rod 4 can be mass-produced without personalized customization, which can reduce production costs and improve production efficiency. The fixing portion 3 designed and processed separately is bonded to the maxillary shell-shaped dental instrument 1 or the mandibular shell-shaped dental instrument 2 by bonding.
