Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontics, in particular to a snore stopper and a dental orthodontic system. Background Art

[0002] At present, some patients have symptoms of dento-maxillary deformity and need to adjust the relationship between the upper and lower jaw positions, such as guiding the mandible to protrude forward. Some patients have obstructive sleep apnea hypopnea syndrome. Obstructive sleep apnea hypopnea syndrome is characterized by repeated obstruction of the upper airway during sleep, causing apnea, hypopnea and sleep disorders, manifested as snoring during sleep, hypoxemia and daytime sleepiness, etc. In recent years, with the in-depth research of multiple disciplines, OSAHS is considered to be a high-risk factor for cardiovascular and cerebrovascular system diseases such as hypertension, cor pulmonale and cerebral infarction. The main reason for OSAHS is that the upper respiratory tract and pharyngeal soft tissues of the patient are relaxed or collapsed during sleep, resulting in airway stenosis or obstruction.

[0003] A commonly used non-surgical treatment method for OSAHS is to wear a shell-shaped dental instrument in the mouth of OSAHS patients during sleep, which can keep the patient's mandible in an appropriate protruded position, make the pharyngeal airway unobstructed, reduce or eliminate the compression of the tongue body on the soft palate and uvula, and make the palatopharyngeal airway also become unobstructed, thereby increasing the air volume and effectively eliminating or reducing the number of apneas and snoring.

[0004] The traditional snore stopper / shell-shaped dental instrument currently used clinically is integrally formed, and there are many insurmountable disadvantages from production to actual use. First of all, the traditional snore stopper needs to take a model, and the production process is complex and cumbersome; secondly, it is very difficult for patients to wear the traditional snore stopper in place; thirdly, due to the rigid connection between the upper and lower jaws, the temporomandibular joint will feel stiff after the patient wears it for one night, and the comfort is very poor, resulting in reduced compliance; thirdly, the connection part of the traditional snore stopper is thick and heavy, squeezing the activity space of the tongue body, and the patient cannot drink water after wearing it because of its rigid connection; thirdly, after wearing the traditional snore stopper, there is no activity space between the upper and lower teeth, and once worn, the patient cannot speak. If you need to speak, you need to take it off again; thirdly, the traditional snore stopper is generally fixed by a metal clasp, and it is easy to loosen during night wear after long-term removal and wearing, affecting the wearing effect.

[0005] In addition, one of the pain points in using existing shell-shaped dental appliances for guiding mandibular protrusion is the inability to locate the ideal mandibular position at low cost and efficiently. In terms of the snoring prevention effect, the further the mandible protrudes forward, the better the snoring prevention effect. However, in terms of patient comfort, an overly protruded mandible will cause many discomforts, leading to a decrease in compliance, and finally causing patients to reject using the snoring prevention device. The appropriate mandibular position can only be determined by constantly trying different mandibular positions based on the experience of dentists. Currently, the snoring prevention methods and snoring prevention devices / shell-shaped dental appliances used clinically are costly on the one hand and cause many discomforts to patients on the other hand. How to quickly and low-costly determine the best mandibular position that can achieve both an ideal snoring prevention effect and patient comfort has always troubled dentists.

[0006] In addition, due to reasons such as cost and difficulty in locating the best mandibular position, it is impossible to gradually guide the mandible forward to achieve a better snoring prevention effect and less discomfort for patients. Summary of the Utility Model

[0047] The following detailed description refers to the accompanying drawings that form a part of this specification. The illustrative embodiments mentioned in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of protection of this application. Under the inspiration of this application, those skilled in the art can understand that many other embodiments can be adopted, and various changes can be made to the described embodiments without departing from the gist and scope of protection of the present utility model. It should be understood that the various aspects of this application described and illustrated herein can be arranged, replaced, combined, separated, and designed in many different configurations, and these different configurations are all within the scope of protection of this application.

[0048] The present utility model provides a shell-shaped dental instrument for guiding the protrusion of the mandible forward. In one embodiment of the present utility model, the shell-shaped dental instrument is an anti-snoring device.

[0049] See Figures 1 to 3 , which is a shell-shaped dental instrument 100 provided by the first embodiment of the present utility model. The shell-shaped dental instrument 100 includes a first shell-shaped body 110 and a second shell-shaped body 120. Among them, the first shell-shaped body 110 has a cavity for accommodating the upper teeth, and the second shell-shaped body 120 has a cavity for accommodating the lower teeth.

[0050] The shell-shaped dental instrument 100 further includes a positioning mechanism 130. The positioning mechanism 130 includes an insertion part 131 and an accommodating part 132. One of the insertion part 131 and the accommodating part 132 is arranged on the first shell-shaped body 110, and the other is arranged on the second shell-shaped body 120. At least a part of the insertion part 131 is inserted into the accommodating part 132.

[0051] The shell-shaped dental instrument 100 is used to guide the protrusion of the mandible forward. Specifically, the shell-shaped dental instrument 100 can be used for anti-snoring.

[0052] In the specific embodiments provided by the present utility model, the insertion part 131 is arranged on the first shell-shaped body 110 and is relatively fixed to the first shell-shaped body 110, and the accommodating part 132 is arranged on the second shell-shaped body 120 and is relatively fixed to the second shell-shaped body 120. Of course, the insertion part 131 can also be arranged on the second shell-shaped body 120 and be relatively fixed to the second shell-shaped body 120, and the accommodating part 132 is arranged on the first shell-shaped body 110 and is relatively fixed to the first shell-shaped body 110.

[0053] During the manufacturing process, the doctor can obtain a digital model of the patient's oral cavity through oral scanning technology and obtain the appropriate mandibular anterior guidance position of the patient, and determine the positions of the insertion part 131 and the accommodating part 132 of the positioning mechanism 130 arranged on the first shell-shaped body 110 and the second shell-shaped body 120 according to the mandibular anterior guidance position.

[0054] During use, when the patient wears the shell-shaped dental appliance 100 in the oral cavity, the first shell-shaped body 110 is worn on the upper jaw, and the second shell-shaped body 120 is worn on the lower jaw. When the upper jaw and the lower jaw bite, at least a part of the insertion part 131 is inserted into the accommodating part 132, positioning the lower jaw in the appropriate mandibular anterior guidance position.

[0055] In this way, the lower jaw can be positioned in the appropriate mandibular anterior guidance position, guiding the lower jaw to gradually protrude forward to obtain a better treatment effect. Moreover, the first shell-shaped body 110 and the second shell-shaped body 120 of this embodiment can be formed by pressure molding, which is comfortable and beautiful. The two are separated, which is beneficial to ventilation and convenient for mass production.

[0056] Furthermore, in this embodiment, the positioning mechanism 130 is used to restrict the relative movement of the insertion part 131 and the accommodating part 132 in the sagittal direction X.

[0057] Wherein, the shell-shaped dental appliance 100 can have a vertical direction Y, and the vertical direction Y can be perpendicular to the occlusal surface. The shell-shaped dental appliance 100 can also have a sagittal direction X, and the sagittal direction X can be perpendicular to the vertical direction Y and perpendicular to the direction from the buccal side to the lingual side. The insertion part 131 is inserted into the accommodating part 132 along the vertical direction Y, that is, the insertion can be completed during the closing process of the upper jaw and the lower jaw.

[0058] In this embodiment, the positioning mechanism 130 is used to restrict the relative movement of the insertion part 131 and the accommodating part 132 in the sagittal direction X, and the insertion part 131 and the accommodating part 132 can be substantially relatively fixed in the sagittal direction X. That is, due to manufacturing tolerances and other reasons, a small displacement, such as within 2 mm, is allowed between the insertion part 131 and the accommodating part 132 in the sagittal direction X. By restricting the relative fixation of the insertion part 131 and the accommodating part 132 in the sagittal direction X, the patient's lower jaw can be maintained in a suitable mandibular position to obtain a better treatment effect.

[0059] The positioning mechanism 130 may also allow the insertion portion 131 and the receiving portion 132 to move relative to each other in the vertical direction Y. When the patient uses the shell-shaped dental instrument 100 for mandibular advancement, there may be a need to open the mouth. Therefore, the positioning mechanism 130 may be configured to allow the first shell-shaped body 110 and the second shell-shaped body 120 to move relative to each other in the vertical direction Y. This can provide a better user experience for the patient and also avoid problems such as difficulty in breathing caused by the complete fixation of the mandible and maxilla.

[0060] Further, in the present embodiment, the insertion portion 131 is at least partially inserted into the receiving portion 132 in the vertical direction Y. The positioning mechanism 130 may further include a limiting portion for limiting the movement of the insertion portion 131 relative to the receiving portion 132 within a certain distance in the vertical direction Y.

[0061] In the present embodiment, the limiting portion for limiting the movement of the insertion portion 131 relative to the receiving portion 132 in the vertical direction Y may be that the limiting portion is used to limit the movement of the insertion portion 131 and the receiving portion 132 within a certain distance in the vertical direction Y. That is, within the certain distance, the mandible opens but the insertion portion 131 is still at least partially inserted into the receiving portion 132, and the two will not separate. By providing the limiting portion, the insertion portion 131 and the receiving portion 132 can be prevented from easily separating, which may affect the treatment effect.

[0062] The length of the insertion portion 131 in the vertical direction Y may be greater than 0.5 mm. Preferably, the length of the insertion portion 131 in the vertical direction Y may be 2 - 6 mm, so as to allow the insertion portion 131 to move relative to the receiving portion 132 within a certain distance in the vertical direction Y and the two will not separate.

[0063] In the present embodiment, the limiting portion includes a limiting convex portion 133 provided at the end of the insertion portion 131 and a limiting groove provided in the receiving portion 132. The limiting convex portion 133 is inserted into the limiting groove. The outer diameter of the limiting convex portion 133 is greater than the outer diameter of the insertion portion 131, and the inner diameter of the receiving portion 132 is less than the outer diameter of the limiting convex portion 133.

[0064] The insertion portion 131 may be cylindrical, and the receiving portion 132 may have a cylindrical receiving groove. The diameter of the insertion portion 131 may be less than or equal to the diameter of the receiving groove. When the insertion portion 131 is inserted into the receiving portion 132, the limiting convex portion 133 is inserted into the limiting groove. During the insertion process, when the limiting convex portion 133 passes through the receiving portion 132, the limiting convex portion 133 undergoes elastic deformation.

[0065] The inner diameter of the limiting groove can be larger than the inner diameter of the accommodating portion 132. When the limiting convex portion 133 enters the limiting groove, the elasticity is released, so that the limitation in the vertical direction Y can be realized. During the process of the patient using the shell-shaped dental instrument 100, the degree of mouth opening of the patient will be restricted. During the opening process of the upper jaw and the lower jaw, the patient needs to apply a certain force to overcome the elastic force of the limiting convex portion 133 to cause elastic deformation of the limiting convex portion 133 before the insertion portion 131 can be pulled out from the accommodating portion 132. Thus, during use, under the action of the limiting portion, the insertion portion 131 and the accommodating portion 132 will not easily separate, and the lower jaw can be maintained in a more appropriate position to obtain a better treatment effect.

[0066] In this embodiment, the outer diameter of the limiting convex portion 133 is smaller than the inner diameter of the limiting groove.

[0067] In this way, the limiting convex portion 133 can move within the limiting groove, thereby providing a certain clearance for the opening of the upper jaw and the lower jaw and allowing the movement of the lower jaw.

[0068] The insertion portion 131 is cylindrical, and the limiting convex portion 133 is provided at the free end of the insertion portion 131 and is spherical. The diameter ratio of the insertion portion 131 to the limiting convex portion 133 can be 1:1.05 to 1:1.5. In this way, the resistance during the process of the insertion portion 131 being inserted into the accommodating portion 132 or the process of separating the two can be reduced.

[0069] Certainly, in other embodiments of the present invention, the limiting portion can also be used to fix the insertion portion 131 and the accommodating portion 132. Similarly, the limiting portion includes a limiting convex portion 133 provided at the end of the insertion portion 131 and a limiting groove provided in the accommodating portion 132. The limiting convex portion 133 is inserted into the limiting groove. The outer diameter of the limiting convex portion 133 is larger than the outer diameter of the insertion portion 131, and the inner diameter of the accommodating portion 132 is smaller than the outer diameter of the limiting convex portion 133. However, the outer diameter of the limiting convex portion 133 can be larger than or equal to the inner diameter of the limiting groove. When the patient wears the shell-shaped dental instrument, the upper jaw and the lower jaw of the patient are relatively fixed and basically cannot move, and the patient cannot open the mouth, completely avoiding the displacement caused by actions such as the patient opening the mouth. Further, in this embodiment, the positioning mechanism 130 is integrally formed with the first shell-shaped body 110 and the second shell-shaped body 120.

[0070] The shell-shaped dental instrument 100 includes a buccal side and a lingual side. The positioning mechanism 130 can be provided on the buccal side of the shell-shaped dental instrument 100. In a specific embodiment, the insertion portion 131 is provided on the buccal side of the first shell-shaped body 110, and the accommodating portion 132 is provided on the buccal side of the second shell-shaped body 120. Certainly, the positioning mechanism 130 can also be provided on the lingual side of the shell-shaped dental instrument 100.

[0071] The first shell-shaped body 110 and the second shell-shaped body 120 include opposite occlusal surfaces, see Figure 6, in another embodiment of the present utility model, the positioning mechanism 130 can also be arranged on the engaging surface of the first shell-shaped body 110 and the second shell-shaped body 120. For example, the insertion portion 131 is arranged on the engaging surface of the first shell-shaped body 110, and the accommodating portion 132 is arranged on the engaging surface of the second shell-shaped body 120.

[0072] In this embodiment, the thicknesses of the first shell-shaped body 110 and the second shell-shaped body 120 are different. In this way, the elastic moduli of the first shell-shaped body 110 and the second shell-shaped body 120 are different, the elastic moduli of the insertion portion 131 and the accommodating portion 132 are different, and the elastic moduli of the limiting convex portion 133 and the limiting groove are different. Thus, it is convenient for the limiting convex portion 133 to undergo elastic deformation when inserted, providing a good limiting effect. At the same time, when the patient wears it, it can be clearly perceived whether the limiting convex portion 133 is inserted into the limiting groove, improving the wearing experience of the patient.

[0073] The first shell-shaped body 110 and the second shell-shaped body 120 can be formed by diaphragm pressing, and the diaphragms of the first shell-shaped body 110 and the second shell-shaped body 120 have different thicknesses. At the same time, by using diaphragms with different thicknesses for manufacturing,

[0074] Among them, the different thicknesses of the first shell-shaped body 110 and the second shell-shaped body 120 can be the different thicknesses at the corresponding positions of the first shell-shaped body 110 and the second shell-shaped body 120. For example, the thicknesses of the first shell-shaped body 110 and the second shell-shaped body 120 at the position where the positioning mechanism 130 is arranged are different.

[0075] Specifically, in this embodiment, the thickness of the diaphragm of the shell-shaped body provided with the insertion portion 131 can be greater than the thickness of the diaphragm of the shell-shaped body provided with the accommodating portion 132. That is, when the insertion portion 131 is arranged on the first shell-shaped body 110 and the accommodating portion 132 is arranged on the second shell-shaped body 120, the thickness of the diaphragm for manufacturing the first shell-shaped body 110 is greater than the thickness of the diaphragm for manufacturing the second shell-shaped body 120. In this way, the strength of the insertion portion 131 is greater, and it can be avoided that the insertion portion 131 deforms when the limiting convex portion 133 is stressed during use.

[0076] In other embodiments provided by the present utility model, the positioning mechanism 130 can be bonded or welded or riveted to the first shell-shaped body 110 and the second shell-shaped body 120. Specifically, for example, the first shell-shaped body 110, the second shell-shaped body 120, the insertion portion 131, and the accommodating portion 132 can be formed separately. The insertion portion 131 can be bonded or welded or riveted to the first shell-shaped body 110, and the accommodating portion 132 can be bonded or welded or riveted to the second shell-shaped body 120.

[0077] Of course, fixing seats can also be provided on the first shell-shaped body 110 and the second shell-shaped body 120, and then the positioning mechanism 130 can be installed on the fixing seats. The fixing seats can be integrally formed with the first shell-shaped body 110 and the second shell-shaped body 120, and can be fixed to the first shell-shaped body 110 and the second shell-shaped body 120 by bonding, welding or riveting.

[0078] Further, referring to Figure 4 , in this embodiment, the positioning mechanism 130 is disposed in the posterior tooth region. The shell-shaped dental instrument 100 includes a pair of positioning mechanisms 130 respectively disposed on the left and right sides.

[0079] Among them, the left and right orientations of the shell-shaped dental instrument 100 can be defined with reference to the left and right orientations of the patient. The left side of the patient can be the left side of the shell-shaped dental instrument 100, and the right side of the patient can be the right side of the shell-shaped dental instrument 100. The two pairs of positioning mechanisms 130 can be symmetrically arranged, so as to achieve better positioning of the mandible.

[0080] Further, referring to Figure 5 , in this embodiment, the positioning mechanism 130 may include at least two adjacent receiving portions 132 and an insertion portion 131 that can be selectively matched with any one of the receiving portions 132. The insertion portion 131 is inserted into different receiving portions 132, and the mandible can correspond to different anterior mandibular guidance positions. In this way, during use, the most suitable anterior mandibular guidance position can be selected according to the actual situation of the patient.

[0081] In this embodiment, the positioning mechanism 130 may include two pairs of receiving portions 132 and a pair of insertion portions 131. The pair of insertion portions 131 can be selectively inserted into any pair of receiving portions 132. It can be understood that the positioning mechanism 130 may include two adjacent receiving portions 132 on the left side and two adjacent receiving portions 132 on the right side. The two receiving portions 132 on the left side and the two receiving portions 132 on the right side can be symmetrically arranged.

[0082] During the process of the patient wearing, according to the situation of the patient, the insertion portion 131 can be selectively inserted into one of the receiving portions 132, so as to guide the mandible of the patient to a suitable mandibular position.

[0083] Of course, the positioning mechanism 130 can also include at least two adjacent insertion portions 131 and a receiving portion 132 that can be selectively matched with any one of the insertion portions 131. Similarly, the receiving portion 132 is matched with different insertion portions 131, and the mandible corresponds to different anterior mandibular guidance positions.

[0084] In this embodiment, the positioning mechanism 130 may also include a pair of receiving portions 132 and two pairs of insertion portions 131. Any pair of insertion portions 131 can be selectively inserted into the receiving portion 132. Similarly, in this embodiment, when different insertion portions 131 are inserted into the receiving portion 132, the patient's mandible can correspond to different mandibular positions. During wearing, one pair of insertion portions 131 can be selectively inserted into the receiving portion 132 according to the specific situation of the patient, so as to guide the patient's mandible to a suitable mandibular position.

[0085] See Figure 3 , in this embodiment, a reinforcing portion 135 is provided in the insertion portion 131. Among them, when the diaphragm is hot-pressed to form a shell-shaped body, the reinforcing portion 135 can be directly embedded therein, or after the shell-shaped body is formed, the reinforcing portion 135 can be embedded into the insertion portion 131. The reinforcing portion 135 can strengthen the insertion portion 131, preventing deformation of the insertion portion 131 caused by actions such as the patient opening the mouth, which may affect the treatment effect.
