Description

Technical Field

[0001] This utility model relates to the fields of teeth whitening, health care and medical treatment, specifically to an oral care device, and in particular a teeth whitening tray. Background Technology

[0002] Teeth whitening has become an increasingly popular oral care need. Currently, the mainstream whitening methods on the market mainly include custom-made trays and non-custom-made whitening strips.

[0003] Custom-made dental trays typically require first taking an impression of the user's teeth and creating a plaster model. Then, a tray is fabricated on the model using processes such as thermoforming to perfectly fit the individual's teeth. These trays are comfortable to wear, but the process is complex, requires skilled technicians, and is time-consuming and costly. While the later-developed thermoplastic bonding type simplifies the process, it still requires heating and softening, as well as intraoral shaping, demanding a higher level of user skill.

[0004] Another widely used technology is flexible whitening patches. These typically consist of a flexible plastic strip coated with whitening gel. However, this structure suffers from insufficient adhesion and is prone to shifting during oral activity, affecting the whitening effect. Furthermore, to prevent shifting, the product usually restricts normal oral movement during wear, reducing the user experience.

[0005] To address the aforementioned issues, the patent specification with publication number US20110311938A1 proposed a non-customizable disposable flexible dental tray solution. This type of product attempts to balance ease of use and tooth fit through pre-filled whitening gel and a basic anatomical design. However, existing designs still have structural flaws: firstly, whitening gel leakage is prone to occur under pressure during use, which not only irritates the gum tissue but also affects the whitening effect; secondly, the retention structure of the dental tray is not well-designed and is prone to displacement within the oral cavity, reducing comfort and reliability.

[0006] In summary, existing custom-made dental trays suffer from high manufacturing costs and complex processes; while whitening strips are convenient to use, their retention reliability is poor, severely impacting user experience and treatment compliance; and non-custom-made dental trays are prone to leakage and slippage. Therefore, there is an urgent need in this field for a novel teeth whitening device that combines convenience, good fit, and reliable retention to solve the aforementioned technical problems and ensure a smooth and comfortable whitening treatment.

[0013] Furthermore, the lip and buccal wall notches and the tongue wall notches are arc-shaped, with widths ranging from 1 mm to 4 mm and depths ranging from 1.5 mm to 3 mm, respectively.

[0014] Furthermore, the crest height of the wavy convex structure is 1.5 mm to 2 mm, the trough depth is 0.8 mm to 1.2 mm, and the spacing between adjacent crests is 4 mm to 5 mm.

[0015] Furthermore, the mesh texture is a diamond mesh texture.

[0016] Furthermore, the side length of the grid units of the labial and buccal wall mesh texture and the tongue wall mesh texture are independently 1.5 mm to 2.5 mm, and the depth is independently 0.02 mm to 0.05 mm.

[0017] Compared with the prior art, the advantages of this utility model are as follows: (1) Ready to use, convenient and efficient: This utility model eliminates the need for users to mix and fill the whitening gel themselves by pre-filling the whitening gel with a precise dose. This not only avoids the difference in whitening effect caused by inaccurate dosage or uneven application, but also eliminates the complicated preparation process before use of traditional whitening trays. It combines the convenience of disposable whitening patches with the comprehensive coverage advantage of whitening tray devices.

[0018] (2) Tight fit and reliable retention: Through the synergistic effect of the (arc-shaped) notch, the wavy raised structure on the bottom wall, and the (diamond-shaped) mesh texture on the inner surface, the non-customized denture can more effectively adapt to the dental arch shape and tooth surface contour of different users. Among them, the notch enhances the flexibility of the front of the denture, the wavy raised structure improves the fit with the occlusal surface of the posterior teeth, and the mesh texture increases friction and gel adhesion. This comprehensive structural design significantly improves the fit accuracy and anti-displacement ability of the denture, so that it can maintain stable retention during the user's daily oral activities such as swallowing and light speech.

[0019] (3) Sealing and leak prevention, protecting gums: The wavy grooves on the labial and buccal walls and the wavy grooves on the lingual wall can form a more comfortable and flexible line contact with the user's gum edge, effectively improving the sealing of the tray edge. This structure can significantly reduce the leakage of whitening gel caused by the compression of the tray by the movement of the lips and tongue, thereby reducing the risk of irritation to the soft tissue of the gums and enhancing the safety and comfort of use.
