Description

TECHNICAL FIELD

[0001] The utility model relates to dental appliance, especially a jaw pad, a jaw pad assembly and a shell-shaped appliance. BACKGROUND

[0002] In the orthodontic field, jaw position adjustment is an important treatment link because it not only involves the alignment of teeth, but also is closely related to occlusal function, facial aesthetics, etc. In many orthodontic cases, patients have malocclusion, such as deep overbite, reverse bite (overbite), open bite, etc. Through jaw position adjustment, the normal vertical and transverse relationship between the upper and lower jaws can be restored, ensuring that the upper and lower jaws can be in correct contact, thereby improving masticatory efficiency and reducing the risk of temporomandibular joint disease. Jaw reconstruction technology can positively affect the facial profile of some patients in conjunction with tooth correction, such as improving protruding chin, small chin, etc., making the face more harmonious and beautiful. Incorrect jaw position can cause unclear pronunciation, difficulty swallowing, sleep apnea, etc. Jaw position adjustment helps to prevent and solve these problems.

[0003] Currently, invisible orthodontics is becoming more and more popular. The combination of jaw pads and invisible orthodontic aligners can greatly play the role of both: performing tooth correction while adjusting the jaw position. However, the strength of the air bubble made directly from the transparent aligner for the jaw pad often does not meet the expected requirements. At the same time, during jaw position adjustment, the jaw pad usually does not need to be replaced frequently, but since the transparent aligner is a consumable, a new one needs to be replaced every certain period of time. If the jaw pad is replaced together with the invisible orthodontic aligner, it will lead to waste and increase in cost. SUMMARY

DETAILED DESCRIPTION

[0074] The utility model will be further illustrated by way of examples below, but the utility model is not limited in the scope of the examples.

[0075] Embodiment 1

[0076] The embodiment provides a jaw pad 100, as shown in the structural schematic view. Figures 1-9 The jaw pad 100 includes an upper surface 110 and a lower surface 120, and the upper surface 110 and the lower surface 120 are respectively used for adapting to an upper tooth part and a lower tooth part. One of the upper surface 110 and the lower surface 120 has an accommodating groove 121, and the accommodating groove 121 is used for covering at least part of the side surface of the tooth 30 in the height direction of the tooth 30. At least one side wall of the accommodating groove 121 is detachably connected to the side surface of the upper tooth part or the side surface of the lower tooth part along the dental arch direction D of the tooth.

[0077] The accommodation groove 121 can cover at least part of the side surface of the tooth, so that the jaw pad 100 has more areas in contact with the tooth, not only can have more stable connection with the tooth, but also the side wall of the accommodation groove 121 can be used as a position for setting a corresponding detachable structure, so that the jaw pad 100 can form a detachable connection with the tooth on the side of the tooth, which not only further improves the connection performance, but also avoids affecting the upper and lower surfaces 120 which play a role in correction. By using the structure in the scheme, the jaw pad 100 itself can provide sufficient strength, and the jaw pad 100 can be reliably connected with the upper tooth part or the lower tooth part, so as to achieve the expected correction effect.

[0078] In actual use, the jaw pad 100 is usually arranged in a substantially horizontal direction between the upper teeth and the lower teeth, and in the use state, the surface for supporting the upper teeth is the upper surface 110, and the surface for supporting the lower teeth is the lower surface 120. Among them, the upper tooth part can be the upper teeth, or the shell-shaped aligner 300 sleeved on the upper teeth; the lower tooth part can be the lower teeth, or the shell-shaped aligner 300 sleeved on the lower teeth; the jaw pad 100 in the embodiment can be matched with the tooth 30 or the shell-shaped aligner 300 as needed. As shown in Figure 1 , the lower surface 120 of the jaw pad 100 is detachably connected with the lower teeth, and the upper surface 110 of the jaw pad 100 is used to contact the upper tooth part, which can be the upper teeth or the shell-shaped aligner 300 sleeved on the upper teeth as needed; as shown in Figure 3 , the lower surface 120 of the jaw pad 100 is detachably connected with the shell-shaped aligner 300 sleeved on the lower teeth, and the upper surface 110 of the jaw pad 100 is used to contact the upper tooth part, which can be the upper teeth or the shell-shaped aligner 300 sleeved on the upper teeth as needed. Usually, the jaw pad 100 is arranged at the posterior teeth, and the jaw pad 100 can be arranged at the posterior teeth on both sides of the oral cavity.

[0079] As shown in Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the upper surface 110 and the lower surface 120 of the jaw pad 100 are concave-convex structures, and each can be provided with a correction groove corresponding to the expected correction position of the jaw position and used for accommodating the upper tooth part or the lower tooth part. The accommodation groove 121 described above can extend a longer length in at least one of the buccal side and the lingual side in the dentition direction D based on the correction groove of the upper surface 110 or the lower surface 120 (the lower surface 120 shown in the figure), and cover at least part of the side surface of the tooth. Correspondingly, the part of the accommodation groove 121 other than the correction groove is preferably adapted to the shape of the tooth. Among them, the position relationship between the jaw pad 100 covering the side surface of the tooth is that the jaw pad 100 can be in contact with the tooth 30 directly or in contact with the shell-shaped appliance 300 sleeved on the tooth according to the actual situation. Therefore, a detachable structure is arranged between the side wall of the accommodation groove 121 and the side surface of the upper tooth part or the lower tooth part to detachably connect the jaw pad 100 with the upper tooth part or the lower tooth part.

[0080] As a preferred implementation, as shown in Figures 1-4 In the buccal-lingual direction BL, the width of the jaw pad 100 is greater than the width of the upper tooth part or the lower tooth part connected with the jaw pad 100. On the one hand, a larger occlusal area can be obtained to make the occlusion more stable; on the other hand, a larger tooth coverage area can also be obtained to make the jaw pad 100 more stable in connection with the tooth. Preferably, the ratio of the width of the jaw pad 100 to the width of the tooth 30 ranges from 1.1 to 1.8.

[0081] In the buccal-lingual direction BL, as shown in Figure 1 The width of the jaw pad 100 is greater than the width of the tooth 30, as shown in Figure 3 The width of the jaw pad 100 is greater than the width of the shell-shaped appliance 300. Preferably, the jaw pad 100 extends beyond the buccal side and the lingual side of the tooth 30, so that the jaw pad 100 extends a side wall on both sides of the tooth 30 in the dentition direction D. In other embodiments, the jaw pad 100 can also extend beyond only one side of the tooth 30, which can be the buccal side or the lingual side.

[0082] As a preferred implementation, as shown in Figures 1-4 Along the dentition direction D of the tooth 30, the jaw pad 100 covers at least two teeth 30. On the one hand, the jaw pad 100 can be in contact with more teeth 30 to improve the jaw position correction effect, and on the other hand, the contact area with the upper tooth part or the lower tooth part is larger, which can also be more stable.

[0083] As shown in Figure 1 and Figure 3As shown, the jaw pad 100 covers the teeth 30 and the posterior teeth part of the shell-shaped appliance 300, at the lower surface 120 of the jaw pad 100, the jaw pad 100 covers three teeth 30 of the posterior teeth, at the upper surface 110 of the jaw pad 100, the jaw pad 100 can accommodate two complete teeth 30 and part of another tooth 30. In actual implementation, the coverage area of the upper surface 110 and the lower surface 120 can be configured respectively according to requirements.

[0084] As a preferred implementation, the height range of the jaw pad 100 along the height direction H of the teeth 30, based on the bottom surface of the upper teeth part or the top surface of the lower teeth part, is 1-8mm. The bottom surface of the upper teeth part can be the bottom surface of the teeth 30 or the bottom surface of the shell-shaped appliance 300; the top surface of the lower teeth part can be the top surface of the teeth 30 or the top surface of the shell-shaped appliance 300.

[0085] For the buccal side wall 130 and the lingual side wall 140 of the accommodation groove 121, both can have the same or different height; and in the dental arch direction D of the teeth, the buccal side wall 130 or the lingual side wall 140 can have uniform height or varying height. As shown in Figure 5 、 Figure 6 and Figure 7 As shown, the buccal side wall 130 has varying height, the height of the buccal side wall 130 in the anterior part is less than that in the posterior part; the lingual side wall 140 has substantially uniform height; the height of the lingual side wall 140 is approximately consistent with the height of the buccal side wall 130 in the anterior part.

[0086] As a preferred implementation, the accommodation groove 121 wraps the upper teeth part or the lower teeth part. The accommodation groove 121 is connected with the upper teeth part or the lower teeth part in a wrapping manner, that is, the inner surface of the accommodation groove 121 can be fitted with the outer surface of the upper teeth part or the lower teeth part and exert a certain wrapping force, thereby improving the connection performance between the jaw pad 100 and the upper teeth part or the lower teeth part.

[0087] As a combination of the above implementations, as shown in Figures 1-9 The jaw pad 100 has a substantially cuboid structure form, but there are special-shaped parts on part of the surface, which can be adapted to the outer contour of the teeth 30 or the shell-shaped appliance 300. As shown in Figures 1-4 In the buccal direction, the jaw pad 100 has a wider width compared with the width of the teeth 30, and exceeds the teeth 30 on both sides of the dental arch direction D. Not only can a larger occlusal area be obtained to make the occlusion more stable, but also the lower surface 120 can obtain a larger wrapping area to more stably wrap the teeth 30 or the shell-shaped appliance 300. As shown in Figures 5-9As shown, the upper surface 110 of the jaw pad 100 is substantially horizontal and has a concave correction groove to match the profile of the teeth. The lower surface 120 of the jaw pad 100 is also substantially horizontal and has an inwardly recessed accommodation groove 121 with a buccal side wall 130 and a lingual side wall 140, which wrap around the buccal side and the lingual side of the teeth 30 or the shell aligner 300, respectively, to achieve a larger tooth wrapping area on the lower surface 120 of the jaw pad 100, so that the jaw pad 100 can more stably wrap around the teeth or the shell aligner 300.

[0088] The side walls of the accommodation groove 121 can be detachably connected to the upper teeth part or the lower teeth part through various detachable structure forms. Generally, one part of the detachable structure is arranged on the side wall of the accommodation groove 121, and the other part is arranged on the upper teeth part or the lower teeth part.

[0089] As a preferred embodiment, the side wall of the accommodation groove 121 is detachably connected to the side surface of the upper teeth part or the side surface of the lower teeth part through a clamping structure. The clamping structure as a detachable connection mode can facilitate disassembly and assembly. The clamping structure refers to a type of clamping structure that can achieve fixed connection between the accommodation groove 121 and the teeth part.

[0090] In other embodiments, other ways such as threaded connection, bolt connection, etc. can also be used to achieve detachable connection. In this embodiment, the clamping structure is taken as an example for specific description. The clamping structure can specifically include a clamping groove 150 and a second protrusion, one of which is arranged on the side wall of the accommodation groove 121, and the other is arranged on the upper teeth part or the lower teeth part.

[0091] Specifically, when the side wall has the clamping groove 150, the clamping groove 150 is recessed on the surface of the side wall or penetrates through the side wall along the buccal-lingual direction BL. The side wall of the accommodation groove 121 is provided with the clamping groove 150, which can be connected to the corresponding second protrusion of the upper teeth part or the lower teeth part. Figure 6 As shown, the structure when the clamping groove 150 penetrates through the side wall is shown. In other embodiments, the clamping groove 150 can also not penetrate through the side wall, but can be recessed from the inner surface to the outer surface of the side wall, so as to form a consistent profile on the outer surface of the side wall, avoiding foreign matter entering the space between the clamping groove 150 and the second protrusion on the teeth part.

[0092] Alternatively, when the side wall has a first protrusion (not shown in the figure), the first protrusion extends on the side wall along the buccal-lingual direction BL. The side wall of the accommodation groove 121 is provided with the first protrusion, which can be connected to the corresponding clamping groove 150 of the upper teeth part or the lower teeth part.

[0093] The clamping groove 150 or the first protrusion can extend along the buccolingual direction BL, facilitating the connection of the jaw pad 100 with the upper or lower teeth, and can limit the movement along the dental arch direction D.

[0094] Further, when the side wall has the clamping groove 150, the clamping groove 150 is an arcuate structure, and the edge of the side wall has a clamping opening 151, the size of which is smaller than the diameter of the arcuate clamping groove 150. The movement of the jaw pad 100 in the height direction H of the teeth 30 can be limited. As shown in Figure 7 The central angle of the clamping groove 150 is greater than 180°, and when the clamping groove 150 is connected with the second protrusion on the teeth, the clamping groove 150 can be clamped to the lower half of the second protrusion, limiting the height direction. In addition, the second protrusion is preferably a circular truncated cone, and the clamping groove 150 has an inner contour matching the circular truncated cone second protrusion.

[0095] Alternatively, when the side wall has the first protrusion (not shown in the figure), the first protrusion is a circular truncated cone, and the small end face of the circular truncated cone is arranged close to the teeth 30.

[0096] In specific implementation, either one or both of the two side walls of the accommodating groove 121 can be provided with the clamping structure described above, and preferably, both of the two side walls of the accommodating groove 121 are detachably connected with the upper or lower teeth; and at least one of the side walls of the accommodating groove 121 is provided with a detachable connection. The jaw pad 100 can be detachably connected with the upper or lower teeth on both sides of the dental arch direction D, thereby improving the stability of the connection between the two. As shown in Figure 6 The clamping groove 150 is provided on the buccal side wall 130 and the lingual side wall 140. The clamping groove 150 can also be provided only on the buccal side wall 130 or only on the lingual side wall 140.

[0097] Further, the positions of the detachable connections of the two side walls are staggered in the dental arch direction D of the teeth 30. When the jaw pad 100 is connected to the mouthpiece, the positions of the detachable connections on the mouthpiece are also correspondingly staggered, so that the inserts on the mouthpiece can also be arranged staggered, facilitating demolding. As shown in Figure 6 and Figure 9 The outer side wall of the accommodating groove 121 is provided with two detachable connections, and the inner side wall of the accommodating groove 121 is provided with one detachable connection. The two clamping grooves 150 on the buccal side wall 130 are staggered with the clamping groove 150 on the lingual side wall 140.

[0098] Preferably, the positions of the detachable connections of the two side walls are staggered in the dental arch direction D of the teeth by a distance greater than 1 mm.
