Description

TECHNICAL FIELD

[0001] The utility model relates to oral cavity monitoring and dental photography technical field, especially relate to a mouth gag. BACKGROUND

[0002] In the course of orthodontic treatment, patients are usually required to visit the clinic regularly, and dental professionals judge whether the orthodontic treatment achieves the expected effect by observing the patient's teeth. If the actual treatment result deviates greatly from the orthodontic treatment plan, the dental professional may need to adjust the subsequent treatment plan accordingly.

[0003] After the completion of orthodontic treatment, the patient's tooth position and / or layout may change due to certain reasons, deviating from the tooth position and / or layout achieved by orthodontic treatment. In order to timely discover and correct this deviation, dental professionals need to regularly check the patient's teeth.

[0004] In order to reduce the number of patient visits, a device for patients to take their own tooth photos has appeared. In this way, patients can take their own tooth photos at any time and any place for dental professionals to check, which effectively reduces the number of patient visits and brings convenience to patients.

[0005] Currently, oral cavity monitoring devices on the market are designed by combining a mouth gag and a shooting host. The shooting host is used to provide oral cavity illumination and shooting, and the mouth gag is used to open the labial mucosa in front of the oral cavity to facilitate image acquisition of the shooting host.

[0006] However, the mouth gag currently used in clinical practice has the following problems:

[0007] For example, the product shown in the accompanying drawings (corresponding to patent numbers CN 202740152, CN 203841667, etc.) cannot simultaneously consider high-quality shooting of the left, middle, and right lip angles and the upper and lower occlusal surface angles (as shown in the accompanying drawings). Figure 1 In particular, it cannot shoot the upper and lower occlusal surfaces based on stable shooting angles. Figure 4

[0008] For another example, the product shown in the accompanying drawings (corresponding to patent number CN 211325741) has a symmetrical structure of the opening side plate and the opening end plate. Although the vertical width and the lateral width of the mouth gag can be adjusted by adjusting the extension of the opening side plate and the opening end plate, the product cannot quickly form a stable shooting angle to shoot the upper and lower occlusal surfaces. Figure 2 For another example, the product shown in the accompanying drawings (corresponding to patent number CN 211325741) has a symmetrical structure of the opening side plate and the opening end plate. Although the vertical width and the lateral width of the mouth gag can be adjusted by adjusting the extension of the opening side plate and the opening end plate, the product cannot quickly form a stable shooting angle to shoot the upper and lower occlusal surfaces.

[0009] Figure 3 ​​The product shown in the middle (corresponding patent number CN210843581) is a metal orthodontic mouth opener. This product also cannot be conveniently integrated with an oral cavity monitoring device camera host and cannot take high-quality photos of the upper and lower occlusal surfaces based on a stable shooting angle.

[0044] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0045] In one specific embodiment, such as Figure 4 As shown, an oral cavity opening device includes a left expansion structure 1, a right expansion structure 2, an upper support structure 3, a lower support structure 4, and a connecting component 5.

[0046] The left expansion structure 1, the right expansion structure 2, the upper support structure 3, and the lower support structure 4 are mounted on the connecting component 5.

[0047] Connection component 5 is used to connect the dental imaging host.

[0048] The upper support structure 3 and the lower support structure 4 are provided with a height difference.

[0049] The height difference is set to create an angle between the imaging surface and the occlusal surface when the oral cavity opener enters the human oral cavity.

[0050] The left expansion structure 1 and the right expansion structure 2 are elastic structures.

[0051] In this embodiment, the left expansion structure 1 and the right expansion structure 2 are symmetrical structures.

[0052] In this embodiment, the height of the left expansion structure 1 and the right expansion structure 2 is not lower than that of the upper support structure 3.

[0053] In this embodiment, the upper surfaces of the left expansion structure 1 and the right expansion structure 2 are curved surfaces.

[0054] In this embodiment, the connecting component 5 is integrally formed with the upper support structure 3 and the lower support structure 4.

[0055] In this embodiment, the cross-section of the connecting component 5 is elliptical.

[0056] In this embodiment, the included angle is greater than 70 degrees.

[0057] The usage process of this embodiment is as follows: the mouth opening device of this embodiment is installed on any compatible dental imaging host on the market through the connecting component 5 (the connecting component 5 can be customized according to the shape of the dental imaging host, as long as it can meet the connection and a through hole for imaging is reserved), and then the dental imaging host can be turned on to take pictures.

[0058] It should be noted that since the innovation of this embodiment lies in the shape and structure of the mouth opener, which is not related to the specific composition of the dental imaging host, this embodiment does not specifically disclose the specific structure of the dental imaging host. However, those skilled in the art should know that as long as a dental imaging host is capable of imaging, it can basically be adapted to the mouth opener of this embodiment. It is only necessary to design the connecting component 5 to include a connecting structure for connection with it, such as a snap-fit, threaded hole or other common connecting structure.

[0059] The image captured by the opening device in this embodiment is as follows: Figure 5 As shown.

[0060] It is understood that, compared with similar products, the image captured by the mouth opener of this embodiment is not only clearer but also has a better angle, which can better meet the needs of orthodontic treatment or other dental treatments.

[0061] The advantages of this embodiment are as follows:

[0062] Both the left and right expansion structures of the mouth opener are elastic, allowing for a smaller lateral distance to facilitate insertion into the patient's mouth, while the elasticity is sufficient to open the patient's lips.

[0063] The upper and lower support structures have a height difference due to their different heights, which allows the patient to have a comfortable angle to match the upper and lower jaw surfaces when the occlusal surface is photographed, making it convenient for the camera lens to achieve an angle of more than 70 degrees with the occlusal surface.

[0064] The left and right expansion structures of the mouth opener have been optimized in terms of curvature for contact with the patient's oral cavity, improving the comfort of contact, and the mouth opener will not obstruct the teeth during photography.

[0065] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
