TECHNICAL FIELD

[0001] The utility model relates to medical appliance technical field, concretely is a silica gel appliance with high structural strength. BACKGROUND

[0002] In the field of orthodontic treatment, silica gel appliances are favored by the majority of patients due to their comfort, aesthetics, and ease of cleaning. However, traditional silica gel appliances have some problems in actual application. On the one hand, the structural strength is insufficient, and deformation may occur due to external forces such as chewing during long-term wear, affecting the stability of the treatment effect. On the other hand, conventional appliances do not fully consider the breathing needs of patients during wear, especially for patients who habitually breathe through their mouths, which may exacerbate the difficulty of breathing after wearing the appliance, resulting in poor wearing experience and reduced patient compliance. The utility model aims to provide a silica gel appliance with high structural strength and breathing function to solve the above-mentioned problems in the prior art. SUMMARY

[0003] The utility model aims to provide a silica gel appliance with high structural strength to solve the problems in the prior art mentioned in the background, wherein the silica gel appliance is provided with upper and lower occlusal zones on the top and bottom of the appliance body. This design makes the appliance fit the teeth more closely and accurately. When the patient chews and generates external force, the tooth-shaped grooves can better distribute the stress, effectively reducing local stress concentration, and greatly improving the overall structural strength of the appliance.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a silica gel appliance with high structural strength, comprising an arc-shaped silica gel appliance body, wherein the top and bottom of the silica gel appliance body are provided with upper and lower occlusal zones, respectively, and a plurality of tooth-shaped grooves are arranged on the upper and lower occlusal zones, the distribution position of the tooth-shaped grooves matches the distribution of human teeth, a through hole is formed in the middle of the outer side of the silica gel appliance body, the through hole penetrates the silica gel appliance body, and the through hole serves as a breathing hole.

[0005] To further optimize the utility model, the following technical solutions can be preferred:

[0006] Preferably, a V-shaped recessed avoidance groove is formed on the silica gel appliance body corresponding to the position of the human upper lip ligament.

[0007] Preferably, the through hole is a circular hole, and a plurality of through holes are arranged side by side.

[0008] Preferably, the silica gel appliance body is integrally formed.

[0009] Preferably, the through hole section is a trapezoidal hole, and upper and lower connecting holes are respectively arranged at positions corresponding to the through holes in the upper and lower bite areas.

[0010] Preferably, the through hole, the upper connecting hole and the lower connecting hole are symmetrically arranged in two groups to form double snore stopping channels.

[0011] Preferably, protruding parts are arranged on the silicone aligner body at positions corresponding to the inner and outer sides of the upper and lower bite areas.

[0012] Compared with the prior art, the silicone aligner has the following beneficial effects:

[0013] (1) Enhanced structural strength: The silicone aligner is provided with upper and lower bite areas on the top and bottom of the silicone aligner body, and the areas are provided with tooth-shaped grooves matching the tooth distribution of the human body. This design makes the aligner fit the teeth more closely and accurately. When the patient chews and generates external force, the tooth-shaped grooves can better disperse the stress and effectively reduce local stress concentration, greatly improving the overall structural strength of the aligner, reducing the risk of deformation caused by external force, and thus ensuring the stability and continuity of the treatment effect.

[0014] (2) Improved breathing experience: A through hole is arranged in the middle of the outer side of the silicone aligner body as a breathing hole. This innovative design fully considers the breathing needs of the patient. For patients who are used to breathing through their mouths, the breathing hole can provide an additional air flow channel for them after wearing the aligner, avoiding the problem of aggravated breathing difficulty caused by the obstruction of the aligner. Good breathing experience helps to improve the patient's compliance in wearing the aligner, making the patient more willing to cooperate with long-term orthodontic treatment, thereby improving the success rate of treatment.

[0015] (3) Improved overall comfort: The increase in structural strength reduces the accidental compression of the aligner on the oral tissues, and the arrangement of the breathing hole optimizes the breathing condition. The two work together to significantly improve the overall comfort of the patient when wearing the aligner. The patient does not have to worry about the aligner being easily damaged and affecting the correction process, and can also maintain smooth breathing, making orthodontic treatment in a comfortable state.
