Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to a transparent retainer with an open window on the occlusal surface. Background Technology

[0002] After orthodontic treatment, a long period of retention treatment is required. Current types of retainers include clear veneer retainers, lingual retainers, and Halley's retainers. Clear veneer retainers are aesthetically pleasing, but because the veneer is relatively thick, the occlusion of the posterior teeth may not be tight when the retainer is removed after the upper and lower dentitions have been raised, which can affect chewing function. Lingual retainers are aesthetically pleasing and do not require self-removal, but patients cannot use dental floss, which is not conducive to cleaning the interproximal spaces. Halley's retainers are beneficial for posterior occlusion, but the exposed wire on the labial side is less aesthetically pleasing; the palatal base has a relatively strong foreign body sensation and, due to its linear contact with the teeth, relatively poor stability. Utility Model Content

[0003] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a transparent retainer with an open window on the occlusal surface, which solves the problem that existing dental retainers cannot simultaneously achieve aesthetics, stability, comfort, easy cleaning, and facilitating posterior tooth occlusion.

[0004] Technical solution

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] A transparent retainer with an occlusal window includes a maxillary retainer and a mandibular retainer, which are correspondingly arranged and have the same structure. Both the maxillary and mandibular retainers are made of transparent retainers, which are made of membranes. The transparent retainer has a window on the occlusal surface at the posterior tooth position. A retaining wire is bonded to the inner side of the membrane on the buccal and lingual surface of the transparent retainer at the tooth position of the window on the occlusal surface.

[0007] Furthermore, both the maxillary retainer and the mandibular retainer are formed by pressing a pressure-film diaphragm.

[0008] Furthermore, the thickness of the pressure film is 0.75 mm or 1 mm.

[0009] Furthermore, the opening is positioned at the corresponding locations of the patient's first premolar, second premolar, and first and second molar on the maxillary retainer and the mandibular retainer.

[0010] Furthermore, the retaining wire is bonded to the inner side of the diaphragm of the transparent retainer, closely adhering to the height position of the cervical cervical region.

[0011] Furthermore, the retaining wire is wrapped around the mesial proximal surface of the first premolar and the distal proximal surface of the second molar, and is bent tightly against the tooth surface.

[0012] Furthermore, the retaining wire is made of stainless steel round wire or Australian wire bent into shape.

[0013] Furthermore, the retaining wire is first placed on the patient's posterior teeth, and then the transparent retainer is placed on the retaining wire.

[0014] Furthermore, the transparent retainer is bonded to the archwire of the retaining wire. Beneficial effects

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] The retainer provided by this utility model adopts a transparent pressure film with an opening on the occlusal surface connected to the lingual retaining wire. This design not only facilitates posterior tooth occlusion and reduces the impact of the retainer on the patient's chewing, but also achieves a larger retention range, maximizing the retention effect. The anterior tooth part of the retainer has a transparent structure, which is transparent and does not expose the labial wire, making it more aesthetically pleasing. The retaining wire bonded to the film not only provides good positional maintenance for the teeth, but also facilitates cleaning, greatly improving the comfort, aesthetics, and stability of wearing the retainer.

[0018] Figure 2 This is a schematic diagram illustrating the use of Embodiment 1 of this utility model. Detailed Implementation

[0019] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] Combined with appendix Figure 1-2 A transparent retainer with an occlusal window is provided, with corresponding transparent retainers 10 for the upper and lower teeth. Taking the upper retainer as an example:

[0022] The maxillary retainer is a transparent structure made of a pressed film. The film thickness is preferably 0.75mm or 1mm, which has little impact on tooth occlusion and also has a high aesthetic appeal.

[0023] A transparent retainer 10 formed by a membrane is fitted onto the teeth. A window 11 is provided on the occlusal surface of the posterior teeth of the transparent retainer 10. The window 11 extends from the midpoint of the first premolar to the distal point of the second molar. Windows 11 are provided at the positions of the first and second premolars, and the first and second molars. Window 11 is symmetrically provided on both sides of the maxillary transparent retainer 10 on the first and second premolars, and the positions of the windows 11 in the maxillary and mandibular retainers correspond. The retainer 10 allows the first and second premolars, as well as the first and second molars, to work together to achieve the chewing function. This minimizes the impact on chewing when the user is wearing the retainer 10, corrects the user's usage habits, and avoids the phenomenon that occurs with retainers 10 without windows 11. After the retainer 10 is removed, the teeth may not bite tightly because the upper and lower teeth are raised by the retainer 10, which has a certain impact on chewing function.

[0024] Meanwhile, the retainer 10 has a retaining wire 12 inside the diaphragm at the location of the window 11. The retaining wire 12 is provided on the buccal and lingual surfaces of the teeth at the window 11 on the occlusal surface of the transparent retainer 10. The retaining wire 12 is placed on the teeth before the retainer 10 is fitted. The retaining wire 12 is made by bending it tightly against the tooth surface at the cervical 1 / 3 of the labial / buccal side of the posterior teeth and the lingual / palatal side, the mesial proximal surface of the first premolar and the distal proximal surface of the second molar.

[0025] The retaining wire 12 is made of stainless steel round wire or Australian wire.

[0026] After the retainer wire 12 is installed, a 0.75mm or 1mm thick pressure film is pressed onto the outside of the retainer wire 12 and bonded to the archwire to form a modified transparent retainer 10. The film has a window 11 on the occlusal surface of the posterior teeth. This design facilitates the establishment of posterior teeth occlusion, stabilizes the bite, and improves chewing efficiency. The buccal and lingual sides of the posterior teeth, except for the occlusal surface, are wrapped with the film and the relatively rigid archwire, which is conducive to tooth stability. At the same time, there is no exposed wire on the labial / buccal side of the anterior teeth, which is aesthetically pleasing. The retainer 10 can be removed and cleaned by the patient, which is convenient for self-cleaning.

[0027] The mandibular retainer and the maxillary retainer 10 are structurally corresponding. The maxillary retainer also has a window, and the position of the window in the mandibular retainer corresponds to that in the maxillary retainer. At the same time, the window in the mandibular retainer also contains a retaining wire. The windows in the mandibular and maxillary retainers allow the posterior teeth of the upper and lower jaws to perform normal chewing functions without affecting the patient's chewing habits. The retaining wires of the mandibular and maxillary retainers can maintain the function of the patient's posterior teeth, thereby achieving the effect of the retainer on the aesthetics of the anterior teeth area, the stability of the posterior teeth occlusion, and the maximum retention range.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
