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 system with an auxiliary correction device. Background Art

[0002] In the field of orthodontics, with the advancement of technology, bracketless invisible braces have emerged. Bracketless invisible braces are a type of dental braces designed with computer aids and made of transparent polymer elastic materials, such as modern invisible shell-shaped dental braces. It is a series of continuous movable braces that achieve the purpose of dental correction by continuously moving teeth in a small range. It has the advantages of being beautiful, convenient, weak foreign body sensation, and easy to clean, and is increasingly accepted and used by patients. This correction device can not only control the size of the correction force, but also control the time of the correction force. In different stages of correction, only certain teeth can be moved, while other teeth serve as support to complete the correction of teeth.

[0003] In the field of invisible orthodontics, when using shell-shaped dental appliances for oral orthodontics, it is sometimes necessary to use other auxiliary devices in combination for treatment, for example, setting a jaw pad component to open the bite, setting a snoring connection component to suppress snoring, and setting a tongue spike to treat tongue malposition. Especially in the field of invisible orthodontics, the long-distance movement of teeth (such as the retraction of the extraction space) has always been a relatively difficult problem to solve, and it is often necessary to use traction parts for traction. It is necessary to make traction hooks on the invisible appliance for elastic materials such as rubber bands, springs, and steel wires to bundle and provide traction. The stable installation of these auxiliary devices and the invisible appliance is the key to the auxiliary devices assisting the invisible appliance to achieve the corresponding correction function, because if the installation of these auxiliary devices and the invisible appliance is unstable, it will directly affect the size and direction of the auxiliary force provided by these auxiliary devices, thereby failing to achieve its intended treatment purpose.

[0004] Take the traction hook as an example. At present, the traction hook is usually fixed to the invisible braces by bonding. Since the traction hook (usually made of metal material) and the invisible braces (usually made of resin material) are made of different materials, the two are easy to separate and difficult to connect firmly and reliably for a long time. Another way is to groove the edge of the invisible braces to form a traction structure. This structure destroys the continuity of the invisible braces and will reduce the overall correction strength of the invisible braces. What's more serious is that the traction hook formed in this way will cause the edge of the invisible braces to warp during use, which will not only scratch the patient, but also change the direction of the traction force, thereby affecting the correction effect.

[0005] Therefore, it is necessary to provide a device that can stably cooperate with the invisible braces to complete auxiliary correction, which is safe and convenient to use and can assist the invisible braces to complete the corresponding correction function. Utility Model Content

[0036] 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.

[0037] 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.

[0038] 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, teeth 4-8 in the FDI notation, and teeth 1-3 in the anterior tooth area in the FDI notation. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0039] As can be seen from the background technology, in the field of invisible orthodontics, when using shell-shaped dental braces for oral orthodontics, it is sometimes necessary to use other auxiliary devices in combination for treatment. The stable installation of these auxiliary devices and invisible braces is the key to the auxiliary devices assisting the invisible braces to achieve the corresponding correction function. If the installation of these auxiliary devices and invisible braces is unstable, it will directly affect the size and direction of the auxiliary force provided by these auxiliary devices, thereby failing to achieve the expected treatment purpose. Taking the traction hook as an example, the currently commonly used method of bonding to the invisible braces or grooving the edge of the invisible braces to form a traction structure is difficult to be firm and reliable for a long time, which may cause the traction hook to fall off or cause the invisible braces to warp, which will not only scratch the patient, but also change the direction of the traction force, thereby affecting the correction effect.

[0040] Based on this, the applicant proposes a dental instrument system with an auxiliary correction device, characterized in that it includes: a shell-shaped dental instrument and an auxiliary correction device; the shell-shaped dental instrument is a shell that conforms to the shape of human dentition, including a plurality of cavities arranged in a U shape for accommodating a plurality of teeth, and the surface of the cavity is provided with a mounting hole; the auxiliary correction device includes a functional part, a main body part and a retaining part arranged in sequence, and an elastic pre-tightening part; the functional part and the retaining part are respectively located on one side of the outer surface and one side of the inner surface of the cavity; there is a predetermined space between the inner surface of the cavity where the mounting hole is located and the tooth surface of the tooth accommodated in the cavity, so that the tooth and the retaining part do not contact; a limiting surface is provided on the side of the functional part close to the outer surface of the cavity, and the outer contour size of the limiting surface is larger than the aperture size of the mounting hole, which is used to limit the auxiliary correction device The retaining portion is arranged to move in the proximal direction, and the outer contour size of the retaining portion is larger than the aperture size of the mounting hole, so as to limit the movement of the auxiliary orthodontic device in the distal direction; wherein the pre-tightening portion is arranged in a compressed state between the limiting surface and the outer surface of the cavity, or the pre-tightening portion is arranged in a compressed state between the surface on the distal side of the retaining portion and the inner surface of the cavity, wherein the pre-tightening portion is compressed in the axial direction to form a pre-tightening force in the axial direction of the main body to limit the movement of the auxiliary orthodontic device in the axial direction, which can ensure the axial stability of the auxiliary device, so that the auxiliary device can stabilize the direction of the auxiliary force provided, especially along the axial direction of the main body, so as to avoid the inclination of the auxiliary orthodontic device causing unexpected movement of the patient's teeth, thereby assisting the shell-shaped dental appliance to achieve the correction goal.

[0041] Please see Figures 1 to 4As shown, the dental instrument system with an auxiliary correction device 2 of the present application includes a shell-shaped dental instrument 1 and an auxiliary correction device 2; the shell-shaped dental instrument 1 is a shell that conforms to the shape of human dentition, including a plurality of cavities 10 arranged in a U shape for accommodating a plurality of teeth, and a mounting hole 11 is provided on the surface of the cavity 10; the auxiliary correction device 2 includes a functional portion 21, a main body portion 22 and a retaining portion 23 arranged in sequence, and an elastic pre-tightening portion 24; the functional portion 21 and the retaining portion 23 are respectively located on one side of the outer surface and one side of the inner surface of the cavity 10; a limiting surface 211 is provided on a side of the functional portion 21 close to the outer surface of the cavity 10, and an outer contour dimension L1 of the limiting surface 211 is larger than the aperture dimension L of the mounting hole 11, and can limit the movement of the auxiliary correction device 2 in the proximal direction, and an outer contour dimension L2 of the retaining portion 23 is larger than the aperture dimension L of the mounting hole 11, and can limit the movement of the auxiliary correction device 2 in the distal direction. The pre-tightening portion 24 is elastic and can be arranged between the limiting surface 211 and the outer surface of the cavity 10, and is in a compressed state in the axial direction Z of the main body 22. At this time, the pre-tightening portion 24 completely fills the gap between the limiting surface 211 and the outer surface of the cavity 10, and forms a pre-tightening force in the axial direction Z that limits the movement of the auxiliary correction device 2 along the axial direction Z. In another embodiment, the pre-tightening portion 24 can also be arranged in a compressed state between the surface 232 on the distal tooth side of the retaining portion 23 and the inner surface of the cavity 10. At this time, the pre-tightening portion 24 completely fills the gap between the surface 232 on the distal tooth side of the retaining portion 23 and the inner surface of the cavity 10, and forms a pre-tightening force in the axial direction Z that limits the movement of the auxiliary correction device 2 in the axial direction Z.

[0042] It should be noted that, in this embodiment, the auxiliary correction device 2 is a traction device that provides inter-maxillary traction force, and its functional part 21 is a traction part that can hook the elastic part 4 (such as a medical rubber band). This is only used to illustrate the technical solution of this application, and does not limit the application scenario of this application. The setting of the pre-tightening part 24 allows the auxiliary correction device 2 to be installed firmly in the axial direction Z, and can generate a more stable traction force, avoiding unexpected movement caused by the inclination of the traction force, deviation from the expected correction effect, and even correction errors.

[0043] In addition, the retaining portion 23 and the main body 22 can be manufactured as one piece. For example, when the retaining portion 23 passes through the mounting hole 11, it can be elastically deformed to pass through the mounting hole 11. After passing through the mounting hole 11, the retaining member returns to its original shape and is clamped on the inner surface of the cavity 10 where the mounting hole 11 is located. The retaining portion 23 and the main body 22 can also be manufactured separately. The retaining portion 23 and the main body 22 are manufactured separately. After the main body 22 passes through the mounting hole 11, the retaining portion 23 is fixed to the main body 22 by bonding or welding. Alternatively, the retaining portion 23 and the main body 22 are designed as detachable structures for easy disassembly and replacement. There are no restrictions in the present application.

[0044] In the present application, the applicant takes into account the patient's comfort and designs the inner surface of the cavity 10 where the mounting hole 11 is located to form a certain predetermined space 20 with the tooth surface 3 of the tooth accommodated in the cavity 10. The predetermined space 20 can accommodate the retaining portion 23 to prevent the retaining portion 23 from applying a force in the lingual direction to the tooth covered by it when wrapped by the inner surface of the cavity 10. The force acting on the tooth is not the expected force. On the one hand, it will compress the patient's teeth and reduce the patient's comfort. On the other hand, it may cause the tooth to move unexpectedly.

[0045] It is further explained that the predetermined space 20 can be achieved by enlarging the digital dental model of the tooth corresponding to the mounting hole 11 when designing the digital dental model, and then making a shell-shaped dental appliance 1 based on the digital dental model by hot-pressing film. The cavity on the shell-shaped dental appliance 1 covering the tooth is larger than the tooth. At this time, the space between the cavity and the tooth is the predetermined space 20, and finally the mounting hole 11 is made at the corresponding position.

[0046] Further explanation: the contour shape of the side surface 231 of the retaining portion 23 adjacent to the tooth it covers can also be designed to be a curved surface that matches the shape of the tooth surface 33 of the tooth. During the design, the curved surface 231 of the side surface of the retaining portion 23 adjacent to the tooth it covers and the tooth surface 33 are always designed to be equidistant. Such a curved surface design can avoid errors caused by reasons such as manufacturing process, which may cause the retaining portion 23 to contact the tooth surface 33.

[0047] In one embodiment, see Figure 5 and Figure 6As shown, the pre-tightening portion can be sleeved on the outer periphery of the main body 22, and can be an annular pre-tightening plate 34. It can be understood that the pre-tightening plate can also be square, trapezoidal, etc. Further, the annular pre-tightening plate 34 is made of elastic material, and the outer diameter dimension L4 of the annular pre-tightening plate 34 is larger than the aperture dimension L of the mounting hole 11, and the inner diameter dimension L3 of the annular pre-tightening plate 34 is sufficient to be sleeved on the outer periphery of the main body 22, that is, it can be larger than the outer contour dimension of the main body 22; it can also be less than or equal to the outer contour dimension of the main body 22, but it must be sufficient to be sleeved on the outer periphery of the main body 22 under elastic deformation.

[0048] In another embodiment, see Figure 7 and Figure 8 As shown, the pre-tightening portion is a non-closed annular structure 44 having a gap 40 . The non-closed annular structure 44 has a sleeve hole 41 that can be sleeved on the outer periphery of the main body 22 , and the gap 40 is connected to the sleeve hole 41 .

[0049] To further illustrate, the outer contour dimension D2 of the non-closed annular structure 44 is larger than the aperture dimension L of the mounting hole 11; the aperture dimension D1 of the sleeve hole 41 of the non-closed annular structure 44 is sufficient to be sleeved onto the outer periphery of the main body 22, that is, it can be larger than the outer contour dimension of the main body 22; it can also be smaller than or equal to the outer contour dimension of the main body 22, but it must be sufficient to be sleeved onto the outer periphery of the main body 22 under elastic deformation.

[0050] It is further explained that there is a preset distance H between the two ends of the gap 40 in the axial direction Z to provide a compressed space for the non-closed annular structure 44 in the axial direction Z. After being sleeved on the main body 22, the two ends of the gap 40 are compressed in the axial direction Z. Similarly, the non-closed annular structure 44 can be arranged between the limiting surface 211 and the outer surface of the cavity 10, or, between the surface 232 on the far tooth side of the retaining portion 23 and the inner surface of the cavity 10, to form a preload in the axial direction Z.

[0051] In another embodiment, see Figures 9 to 11 As shown, the pre-tightening portion may be an elastic layer 54 (such as Fig. 9 As shown), it can also be an elastic layer 54 (as shown) sprayed on the surface of the distal tooth side of the retention portion 23. Fig.10 and Fig.11 As shown), for example, a layer of edible gel can be sprayed on.

[0052] In another embodiment, see Figure 12 to Figure 14As shown, the pre-tightening part structure of the present application needs to be able to be compressed in the axial direction Z to form a pre-tightening force, so that the auxiliary installation device can be stably installed in the axial direction Z to assist the shell-shaped dental instrument 1 in achieving its correction goal. Therefore, the pre-tightening part 24 has at least one elastic layer 54. When the pre-tightening part 24 is a two-layer structure, one side thereof is the elastic layer 54; when the pre-tightening part 24 is a three-layer structure, the outer layer is the elastic layer 54, and the inner layer may also be the elastic layer 54.

[0053] In one embodiment, see Figures 15 to 18 As shown, the predetermined space is a cavitation boss 60 formed by a side surface of the dental instrument protruding toward the distal tooth direction, the mounting hole 11 is provided on the side wall of the cavitation boss 60 in the distal tooth direction, and the cavitation boss 60 has a receiving cavity inside for receiving the retaining portion 23. The receiving cavity is communicated with the mounting hole 11, and the structure of the mounting hole 11 satisfies: the retaining portion 23 can pass through (can pass through in a compressed state, can also pass through without compression) the mounting hole 11 to be received in the receiving cavity, and when the retaining portion 23 is received in the receiving cavity, the mounting hole 11 can limit the retaining portion 23 from escaping from the receiving cavity along the distal tooth direction.

[0054] In one embodiment, see Figures 19 to 22 As shown, the outer contour dimension L5 of the retaining portion 23 near the insertion end is smaller than the aperture dimension L of the mounting hole 11, and the outer contour dimension L6 of the retaining portion 23 away from the insertion end is larger than the aperture dimension L of the mounting hole 11. When the retaining portion 23 is inserted into the mounting hole 11, the retaining portion 23 is restrained by the mounting hole 11 and gathers inward toward the main body 22, so that the retaining portion 23 passes through the mounting hole 11 and is clamped with the inner surface of the cavity 10 where the mounting hole 11 is located, so as to limit the movement of the retaining portion 23 in the direction opposite to the insertion direction Y.

[0055] It is further explained that the inner surface of the cavity 10 where the mounting hole 11 is located abuts against the retaining portion 23 accommodated therein so that the retaining portion 23 is accommodated in a predetermined position in a predetermined space 20 between the inner surface of the cavity 10 where the mounting hole 11 is located and the tooth surface 3 of the tooth covered by the cavity 10. The retaining portion 23 includes a guide portion 233 and a retaining portion 234 which are sequentially connected, and the guide portion 233 is connected to the main body 22; the guide portion 233 is arranged at a preset angle α with the main body 22, and the guide portion 233 cooperates with the mounting hole 11 to guide the retaining portion 23 to gather inward, wherein the preset angle α is an acute angle between 5 and 80 degrees, and can be between 10 and 60 degrees in actual applications, or can be 20 or 30 degrees; specifically, because the outer contour size of the guide portion 233 away from the retaining portion 234 is smaller than that of the mounting hole 11, the retaining portion 233 can be arranged at a preset angle α with the main body 22, and the guide portion 233 can be arranged at a preset angle α with the mounting hole 11, and the retaining portion 23 can be arranged at a preset angle α with the mounting hole 11. The aperture size L of the hole 11, the part of the guide portion 233 away from the supporting portion 234 is easy to be inserted into the mounting hole 11 via the insertion direction Y. Through the guidance of the guide portion 233, during the gradual insertion of the retaining portion 23, the part of the guide portion 233 near the supporting portion 234 is elastically compressed and gathered inwardly, that is, gathered toward the main body 22, so as to pass through the mounting hole 11. When the retaining portion 23 is accommodated in the predetermined space 20, the supporting portion 234 abuts against the inner surface of the cavity 10 to limit the movement of the retaining portion 23 in the direction opposite to the insertion direction Y.

[0056] It is understood that the above-mentioned abutment refers to abutment without gaps, and the gaps in the figure are only for the convenience of display. The present application is designed in this way so that the auxiliary correction device 2 can be firmly installed on the shell-shaped dental instrument 1 after installation, so as to obtain a stable and desired auxiliary force.

[0057] Further explanation, in this embodiment, there is a gap 237 between at least the portion of the guide portion 233 away from the insertion end and the main body 22 to provide space for the guide portion 233 to gather toward the main body 22. Specifically, the end of the gap 237 away from the connection between the guide portion 233 and the main body 22 is an open structure. It is further defined that there is a gap 237 between at least the portion of the guide portion 233 away from the insertion end and the main body 22 to achieve the inward gathering movement of the guide portion 233. In actual applications, the gap 237 can be achieved by a groove, such as a V-shaped groove.

[0058] To further explain, a side of the guide portion 233 away from the main body portion 22 is a guide surface, and the guide surface may be a plane or a rotational surface. In actual applications, other forms of surfaces may also be used, which is not limited here.

[0059] In another embodiment, see Figure 23 to Figure 25 As shown, compared with the previous embodiment ( Figures 19 to 22 The specific structure of the retaining portion 23 in the illustrated embodiment is different. In the present embodiment, the retaining portion 23 includes a guide portion 233, a second abutting portion 235 and a first abutting portion 236 which are sequentially arranged, and the guide portion 233 is connected to the main body 22; the guide portion 233 and the main body 22 are arranged at a preset angle γ, and cooperate with the mounting hole 11 to guide the guide portion 233 to gather inwardly, and the preset angle γ is an acute angle. Similarly, the preset angle γ ranges from 5 degrees to 80 degrees, and can be between 10 degrees and 60 degrees in actual applications, or can be 20 degrees, 30 degrees, etc.; after the auxiliary correction device 2 is installed, at least the first abutting portion 236 of the retaining portion 23 abuts against the inner surface of the cavity 10 where the mounting hole 11 is located, so as to limit the movement of the retaining portion 23 in the direction opposite to the insertion direction Y; when the retaining portion 23 is accommodated in the predetermined space 20, as Fig.25 As shown, the first abutting portion 236 abuts against the inner surface of the cavity 10 where the mounting hole 11 is located.
