Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a dental orthodontic occlusion device. Background Technology

[0002] In orthodontic treatment, indenting and elongating teeth are common treatment goals, typically achieved by applying traction through other teeth or alveolar bone micro-implants. However, both methods have drawbacks. Traction through other teeth can easily cause unplanned movement, such as tilting of unrelated teeth, while micro-implants, being implants in the human body, can cause trauma and pain to the patient. Summary of the Invention

[0003] In view of the problems in the prior art, the present invention provides a dental orthodontic occlusal device, the dental orthodontic occlusal device including a first occlusal member and a second occlusal member, the first occlusal member and the second occlusal member being pivotally connected, thereby defining a first driving end and a first driven end of the first occlusal member, and a second driving end and a second driven end of the second occlusal member; the first driven end and / or the second driven end are connected to a device fixed to the teeth; the opening and closing of the first driving end and the second driving end are driven by the opening and closing of the upper and lower jaws, and the first driven end and the second driven end are driven to open and close, so that when the first driven end and the second driven end are opened to a specific state, traction force can be provided to the corresponding teeth.

[0004] Furthermore, the opening and closing directions of the first driving end and the second driving end are opposite to the opening and closing directions of the first driven end and the second driven end.

[0005] Furthermore, the opening and closing directions of the first driving end and the second driving end are the same as the opening and closing directions of the first driven end and the second driven end.

[0006] Furthermore, the first driven end and / or the second driven end are connected to a device fixed to the teeth via a connector.

[0007] Furthermore, the connector is elastic.

[0008] Furthermore, the device fixed to the teeth is a dental brace or an accessory placed on the teeth.

[0009] Furthermore, the first driving end and / or the second driving end includes a portion that can contact the occlusal surface of the tooth, thereby enabling the corresponding tooth to directly act on the first driving end and / or the second driving end.

[0010] Furthermore, a fixing structure is provided on the tooth, which acts on the first driving end and / or the second driving end.

[0011] Furthermore, the fixing structure is located on the labial or lingual side of the tooth.

[0012] Furthermore, the fixed structure is provided with a limit structure to restrict the movement trajectory of the first driving end and the second driving end.

[0013] The orthodontic occlusal appliance of this invention utilizes occlusal force, the most basic source of facial power, and converts it into traction force to depress and elongate teeth. This eliminates the need for additional teeth or alveolar bone micro-implants to apply traction, avoiding unplanned movements such as unrelated tooth tilting and the traumatic jaw pain caused by implants. Simultaneously, it can more safely shorten treatment time and reduce the number of braces used in the treatment, reducing the number of follow-up visits and overall treatment duration, achieving twice the result with half the effort in orthodontic treatment.

[0014] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. The accompanying drawings are schematic diagrams or conceptual diagrams, and the relationships between the thickness and width of each part, as well as the proportional relationships between each part, etc., are not entirely consistent with their actual values.

[0036] Example 1

[0037] Figure 1 A schematic diagram of a dental orthodontic occlusal device according to an embodiment of the present invention is shown, including a first occlusal member 100 and a second occlusal member 200. The first occlusal member 100 is a curved rod and is symmetrically arranged. Similarly, the second occlusal member 200 is also a curved rod and is also symmetrically arranged.

[0038] The first engaging member 100 and the second engaging member 200 are pivotally connected. In this embodiment, both the first engaging member 100 and the second engaging member 200 are symmetrical structures, thus providing a symmetrical pair of pivot connection structures. The pivot connection of the first engaging member 100 and the second engaging member 200 can be achieved using conventional methods, such as connecting the first engaging member 100 and the second engaging member 200 with a pin, or by fabricating a shaft on one of the first engaging member 100 and the second engaging member 200 and a hole on the other, achieving the pivot connection through the fit of the shaft and the hole. The specific pivot connection method is not limited here.

[0039] The first engaging member 100 includes a first driving end 110 and a first driven end 120 on both sides of the pivot connection structure, and the second engaging member 200 includes a second driving end 210 and a second driven end 220 on both sides of the pivot connection structure. The bending arrangement of the first engaging member 100 and the second engaging member 200, as well as their pivot connection position, limits the rotation of the first driving end 110 and the second driving end 210 in opposite directions or towards each other, or in other words, the rotation of the first driven end 120 and the second driven end 220 in opposite directions or away from each other. That is, when the first driving end 110 and the second driving end 210 rotate in the closing direction, the first driven end 120 and the second driven end 220 gradually open accordingly, and vice versa.

[0040] This embodiment uses the directional traction of tooth 10 as an example to describe in detail the setting of the orthodontic occlusal device in the oral cavity. The first driven end 120 is connected to the fixing device 400 via a spring 300. The fixing device 400 is a component that is relatively fixed to tooth 10. It can be a bracket or attachment that can be directly glued to tooth 10, or when braces are installed on tooth 10, the fixing device 400 can be a structure that can be connected to braces, such as a hook, ring, post, or block. The two ends of the spring 300 are respectively connected to the first driven end 120 and the fixing device 400.

[0041] When the relative positions of the upper and lower jaws or the upper and lower teeth are kept fixed, bringing the first driving end 110 and the second driving end 210 closer together will cause the first driven end 120 and the second driven end 220 to open accordingly. When the first driven end 120 and the second driven end 220 are opened to a certain extent, the spring 300 enters a stretched state. At this time, under the action of the restoring force of the spring 300, the tooth 10 will be pulled upward.

[0042] This invention provides the driving force for the orthodontic occlusal device through the force of the opening and closing of the upper and lower jaws. In this embodiment, the force generated by the approach of the upper and lower teeth drives the first driving end 110 and the second driving end 210 to approach each other until the upper and lower teeth occlude, which limits the extreme position of the approach of the first driving end 110 and the second driving end 210. As mentioned above, when the relative position of the upper and lower teeth is fixed, driving the first driving end 110 and the second driving end 210 to approach each other can put the spring 300 into a stretched state. When the first driving end 110 and the second driving end 210 are driven by the approach of the upper and lower teeth, since the movement direction of the upper teeth is opposite to the movement direction of the first driving end 110, the spring 300 can be put into a stretched state more quickly.

[0043] The methods by which the first driving end 110 and the second driving end 210 are driven by the movement of the upper and lower jaw teeth include, but are not limited to, the following.

[0044] One implementation method is as follows Figure 2 As shown, the first driving end 110 and the second driving end 210 respectively include a first extension 111 and a second extension 211. The shape and position of the first extension 111 and the second extension 211 are adapted to contact the occlusal surfaces of the upper and lower teeth. Thus, when the upper and lower teeth approach each other, they will contact the first extension 111 and the second extension 211 respectively, so that the first driving end 110 and the second driving end 210 will approach each other as the upper and lower teeth approach each other, thereby driving the first driven end 120 and the second driven end 220 to open in the direction of the upper jaw and the lower jaw respectively. When the opening reaches a certain degree, the spring 300 enters the stretched state. Under the action of the restoring force of the spring 300, the tooth 10 will be pulled upward. When the upper and lower teeth reach the biting state, the first driving end 110 and the second driving end 210 reach their extreme positions of approaching each other, and the first driven end 120 and the second driven end 220 also reach their extreme positions of opening. At this time, the spring 300 is also in the maximum tension state, and the teeth 10 obtain the maximum traction force. This traction force must be at least not less than the expected traction force in order to obtain the expected traction effect. The setting and adjustment of the maximum traction force can be adjusted by the structure of the first biting member 100 and the second biting member 200, or by replacing the spring 300 with a spring of different specifications.

[0045] There are no specific restrictions on the shape of the first extension 111 and the second extension 211, as long as they are suitable for being driven by the upper and lower jaw teeth. They can be strip-shaped, sheet-shaped, or other shapes, with the aim of being suitable for being driven by the upper and lower jaw teeth.

[0046] Another implementation method is as follows Figure 3 As shown, teeth 20 and 30 are respectively equipped with attachments 410 and 420. The positions of attachments 410 and 420 are respectively matched with the positions of the first driving end 110 and the second driving end 210. That is, when the upper and lower teeth approach each other, attachments 410 and 420 abut against the first driving end 110 and the second driving end 210 respectively, thereby driving the first driving end 110 and the second driving end 210 to approach each other, and then driving the first driven end 120 and the second driven end 220 to open in the direction of the upper jaw and the lower jaw respectively. After opening to a certain extent, the spring 300 enters the stretched state, and under the action of the restoring force of the spring 300, it provides an upward traction force to the tooth 10.

[0047] like Figure 4 As shown, the contact surface 411 between attachment 410 and the first driving end 110 is set as an inclined surface. Similarly, the contact surface 421 between attachment 420 and the second driving end 210 is also set as an inclined surface. When the first driving end 110 and the second driving end 210 abut against the contact surfaces 411 and 421 respectively and are driven closer to each other, the inclined surfaces of the contact surfaces 411 and 421 provide the first driving end 110 and the second driving end 210 with a pushing force towards the tooth side, thereby ensuring that the first driving end 110 and the second driving end 210 do not fall out of the working range of attachments 410 and 420 during the driving process. The contact surfaces 411 and 421 are set as planes, but curved surfaces or other similar settings can also be used.

[0048] Another implementation method is as follows Figure 5 and Figure 6 As shown, attachment 410 is provided with a through hole 412 that mates with the first driving end 110. The first driving end 110 can pass through the through hole 412. Similarly, attachment 420 is provided with a through hole 422 that mates with the second driving end 210. The second driving end 210 can pass through the through hole 422. Thus, when attachments 410 and 420 move with the upper and lower teeth, they will also drive the first driving end 110 and the second driving end 210 to move synchronously, thereby driving the opening and closing of the first driven end 120 and the second driven end 220.

[0049] In this embodiment, taking tooth 10 as an example, in actual use, multiple springs 300 are set to be connected to the corresponding teeth according to the specific situation of the teeth to be corrected. At the same time, it can be either the upper teeth or the lower teeth, or both upper and lower teeth can be corrected at the same time.

[0050] In this embodiment, the orthodontic occlusal appliance is positioned on the labial / buccal side of the upper and lower teeth. Similarly, it can also be positioned on the lingual side of the upper and lower teeth.

[0051] Example 2

[0052] Figure 7 A schematic diagram of a dental orthodontic occlusal device according to an embodiment of the present invention is shown, including a first occlusal member 500 and a second occlusal member 600. The first occlusal member 500 is a curved rod and is symmetrically arranged. Similarly, the second occlusal member 600 is also a curved rod and is also symmetrically arranged.

[0053] The first engaging member 500 and the second engaging member 600 are pivotally connected. In this embodiment, both the first engaging member 500 and the second engaging member 600 are symmetrical structures, thus providing a symmetrical pair of pivot connection structures. The pivot connection of the first engaging member 500 and the second engaging member 600 can also employ conventional methods, such as connecting the first engaging member 500 and the second engaging member 600 via a pin, or fabricating a shaft on one of the first engaging member 500 and the second engaging member 600 and a hole on the other, achieving the pivot connection through the cooperation of the shaft and the hole. The specific pivot connection method is not limited here.

[0054] The first engaging member 500 includes a first driving end 510 and a first driven end 520 on both sides of the pivot connection structure, and the second engaging member 600 includes a second driving end 610 and a second driven end 620 on both sides of the pivot connection structure. Unlike Embodiment 1, the first engaging member 500 and the second engaging member 600 are cross-arranged at the pivot connection, thus ensuring that when the first driving end 510 and the second driving end 610 rotate towards each other or move closer together, the first driven end 520 and the second driven end 620 also rotate towards each other or move closer together. That is, the opening and closing of the first driving end 510 and the second driving end 610 is consistent with the opening and closing of the first driven end 520 and the second driven end 620.

[0055] This embodiment uses the directional traction of tooth 10 as an example to describe in detail the setting of the orthodontic occlusal device in the oral cavity. The second driven end 620 is connected to the fixing device 400 via a spring 300. The fixing device 400 is a component that is relatively fixed to tooth 10. It can be a bracket or attachment that can be directly glued to tooth 10, or when braces are installed on tooth 10, the fixing device 400 can be a structure that can be connected to braces, such as a hook, ring, post, or block. The two ends of the spring 300 are respectively connected to the second driven end 620 and the fixing device 400.

[0056] When the relative positions of the upper and lower jaws or the upper and lower teeth are kept fixed, bringing the first driving end 510 and the second driving end 610 closer together will also bring the first driven end 520 and the second driven end 620 closer together. When the first driven end 520 and the second driven end 620 are close to a certain extent, the spring 300 enters a stretched state. At this time, under the action of the restoring force of the spring 300, the tooth 10 will be pulled downward.

[0057] This invention provides driving force for the orthodontic occlusal device through the force of the opening and closing of the upper and lower jaws. In this embodiment, the force generated by the approach of the upper and lower teeth drives the first driving end 510 and the second driving end 610 to approach each other until the upper and lower teeth occlude, which limits the extreme position of the approach of the first driving end 510 and the second driving end 610. Unlike Embodiment 1, the movement direction of the upper teeth is the same as the movement direction of the first driving end 510. Therefore, the configuration of the first occlusal member 500 and the second occlusal member 600 must satisfy the requirement that the stroke of the first driven end 520 and the second driven end 620 must be greater than the stroke of the upper and lower teeth during the approach process. From a geometric point of view, this is easy to achieve and can be adjusted through the structure of the first occlusal member 500 and the second occlusal member 600, such as the position of the first driven end 520 and the second driven end 620, and the selection of the pivot position.

[0058] The methods by which the first driving end 510 and the second driving end 610 are driven by the movement of the upper and lower jaw teeth include, but are not limited to, the following.

[0059] One implementation method is as follows Figure 8As shown, the first driving end 510 and the second driving end 610 respectively include a first extension 511 and a second extension 611. The shape and position of the first extension 511 and the second extension 611 are adapted to contact the occlusal surfaces of the upper and lower teeth. Thus, when the upper and lower teeth approach each other, they will contact the first extension 511 and the second extension 611 respectively, so that the first driving end 510 and the second driving end 610 will approach each other as the upper and lower teeth approach each other, thereby driving the first driven end 520 and the second driven end 620 to approach each other. Since the travel of the first driven end 520 and the second driven end 620 during the approaching process is always greater than the travel of the upper and lower teeth, the spring 300 will be gradually stretched. Under the action of the restoring force of the spring 300, the tooth 10 will be pulled downward. When the upper and lower teeth reach the biting state, the first driving end 510 and the second driving end 610 reach the extreme position of being close to each other, and the first driven end 520 and the second driven end 620 also reach the minimum distance position. At this time, the spring 300 is also in the maximum tension state, and the tooth 10 obtains the maximum traction force. This traction force needs to be at least not less than the expected traction force in order to obtain the expected traction effect. The setting and adjustment of the maximum traction force can be adjusted by the structure of the first biting member 500 and the second biting member 600, or by replacing the spring 300 with a spring of different specifications.

[0060] There are no specific restrictions on the shape of the first extension 511 and the second extension 611, as long as they are suitable for being driven by the upper and lower jaw teeth. They can be strip-shaped, sheet-shaped, or other shapes, with the aim of being suitable for being driven by the upper and lower jaw teeth.

[0061] Another implementation method is as follows Figure 9 As shown, teeth 20 and 30 are respectively equipped with attachments 410 and 420. The positions of attachments 410 and 420 are respectively matched with the positions of the first driving end 510 and the second driving end 610. That is, when the upper and lower teeth approach each other, attachments 410 and 420 abut against the first driving end 510 and the second driving end 610 respectively, thereby driving the first driving end 510 and the second driving end 610 to approach each other, which in turn drives the first driven end 520 and the second driven end 620 to approach each other, and the spring 300 is gradually stretched. Under the action of the restoring force of the spring 300, a downward traction force is provided to the tooth 10.

[0062] like Figure 10As shown, the contact surface 411 between attachment 410 and the first driving end 510 is set as an inclined surface. Similarly, the contact surface 421 between attachment 420 and the second driving end 610 is also set as an inclined surface. When the first driving end 510 and the second driving end 610 abut against the contact surfaces 411 and 421 respectively and are driven closer to each other, the inclined surfaces of the contact surfaces 411 and 421 provide the first driving end 510 and the second driving end 610 with a pushing force towards the tooth side, thereby ensuring that the first driving end 510 and the second driving end 610 do not fall out of the effective range of attachments 410 and 420 during the driving process. The contact surfaces 411 and 421 are set as planes, but curved surfaces or other similar settings can also be used.

[0063] Another implementation method is as follows Figure 11 and Figure 12 As shown, attachment 410 is provided with a through hole 412 that mates with the first driving end 510. The first driving end 510 can pass through the through hole 412. Similarly, attachment 420 is provided with a through hole 422 that mates with the second driving end 610. The second driving end 610 can pass through the through hole 422. Thus, when attachments 410 and 420 move with the upper and lower teeth, they will also drive the first driving end 510 and the second driving end 610 to move synchronously, thereby driving the opening and closing of the first driven end 520 and the second driven end 620.

[0064] In this embodiment, taking tooth 10 as an example, in actual use, multiple springs 300 are set to be connected to the corresponding teeth according to the specific situation of the teeth to be corrected. At the same time, it can be either the upper teeth or the lower teeth, or both upper and lower teeth can be corrected at the same time.

[0065] In this embodiment, the orthodontic occlusal appliance is positioned on the labial / buccal side of the upper and lower teeth. Similarly, it can also be positioned on the lingual side of the upper and lower teeth.

[0066] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
