Description

TECHNICAL FIELD

[0001] The utility model relates to tooth correction technical field, concretely relates to a kind of improved invisible aligner of recovery edentulous space. BACKGROUND

[0002] After premature loss of deciduous teeth, adjacent teeth are prone to displacement and tilting, leading to the narrowing of edentulous space and affecting the eruption of permanent successor teeth. For patients with long-term edentulous space, adjacent teeth are also prone to displacement and tilting, leading to insufficient space for implant restoration.

[0003] Existing devices for opening the space of premature loss of deciduous teeth are mostly metal devices, which have strong foreign body sensation and cannot be disassembled, making cleaning difficult. The restoration of edentulous space in permanent dentition often requires the use of multiple orthodontic appliances, usually in combination with segmental arches, implants, etc., which have poor comfort and require long chair-side operation time. In particular, if the teeth before the edentulous space in permanent dentition are used as intramaxillary anchorage, the anchorage provided is limited and may cause unintended displacement and tilting of adjacent teeth. The teeth pushed distally in the edentulous space may also be twisted and tilted unexpectedly. Therefore, other auxiliary devices such as segmental arches are often required, increasing the difficulty and time of treatment. SUMMARY

[0004] The utility model aims to solve the technical problem of providing an improved invisible aligner for restoring edentulous space, which addresses the issues of requiring multiple auxiliary devices such as segmental arches and implants for edentulous space restoration, poor comfort, and long chair-side operation time.

[0005] TECHNICAL SOLUTION

[0006] To solve the above problems, the utility model provides the following technical solutions:

[0007] An improved invisible aligner for restoring edentulous space includes an invisible aligner with a false tooth inside. A push spring is embedded in the false tooth. The distal end of the invisible aligner has a bubble.

[0008] Further, the position of the false tooth corresponds to the edentulous position of the patient.

[0009] Further, one end of the push spring is fixed to the false tooth, and the other side of the push spring abuts against the molar on the distal side of the false tooth.

[0010] Further, the push spring can be elongated and maintained in the elongated state.

[0011] Further, the mesial side of the invisible aligner is a bracketless invisible aligner.

[0012] Further, the push spring is made of stainless steel wire or Australian wire.

[0013] Furthermore, the cavitation bubble is used to provide a distal movement clearance for the molar pushed by the push spring.

[0014] Furthermore, the denture is a solid plastic structure.

[0015] Furthermore, attachments are provided on the adjacent teeth on both sides of the denture.

[0016] Beneficial effects

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] The technical solution provided by this utility model reduces the number of orthodontic devices in the patient's mouth by setting a push spring to help widen the gap and setting a cavitation bubble on the end of the brace for molar movement, thereby improving the aesthetics of the patient's teeth during the orthodontic process, shortening the chairside operation time of medical staff, and improving comfort. Furthermore, the utility model uses a bracketless clear aligner to wrap around all the teeth on the mesial side of the edentulous gap to form an overall anchorage that pushes the molars backward. Through the attachment of adjacent teeth, it reduces the unintended rotation and tilting of adjacent teeth, assists in aligning adjacent teeth, and helps to form a good proximal relationship after the edentulous restoration is completed. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of Embodiment 1 of this utility model. Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] Combined with appendix Figure 1 This is a modified clear aligner for restoring edentulous spaces. It uses a bracketless clear aligner with embedded push springs to restore spaces from premature loss of deciduous teeth or missing permanent teeth, and to align adjacent teeth. By wrapping the aligner around all teeth mesially within the edentulous space, it creates overall posterior anchorage for the push molars.

[0023] It includes an invisible braces 10, which is made of the invisible braces 10 as the basic structure. Inside the invisible braces 10, a prosthesis 11 is placed at the position of the patient's missing tooth. The prosthesis 11 is a solid structure, preferably a plastic prosthesis, i.e. a resin prosthesis, to maintain the interocclusal distance at the patient's missing tooth site.

[0024] A push spring 12 is provided on the denture 11. One end of the push spring 12 is fixed to the solid denture 11, and the other end of the push spring 12 abuts against the mesial surface of the molar on the distal side of the denture 11. The push spring 12 can push the molar on the distal side of the denture 11 to move with the denture 11 as the support point. The push spring 12 is preferably made of stainless steel round wire or Australian wire to expand the gap between missing teeth. As the number of denture steps increases, the length of the push spring 12 can be gradually increased to gradually increase the pushing force on the distal molar of the denture 11.

[0025] The push spring 12 is installed on the denture and molars and can be stretched by medical staff using instruments. At the same time, the push spring 12 can maintain its stretched state, so as to ensure that the push spring 12 can generate a continuous pushing force on the molars during the orthodontic process. As the orthodontic process progresses, the length of the push spring 12 continues to extend, thereby pushing the molars to move backward and thus widening the gap between missing teeth.

[0026] The Invisible Braces 10 is a bracketless clear aligner. The Invisible Braces 10 covers all the teeth on the mesial side of the edentulous space. The brackets that fix all the teeth on the mesial side of the edentulous space are bracketless clear aligners and form a whole to form an overall anchorage that pushes the molars backward.

[0027] The distal end of the brace 10 has a space reserved for pushing the molars backward. That is, after the brace 10 is installed on the patient's teeth, the distal end of the brace has a vacuole 13 to allow the molars on the distal side of the denture 11 to move. Since the brace 10 is set according to the progress of the orthodontic treatment, a new brace 10 needs to be replaced for each stage of the orthodontic treatment. Therefore, each step of the brace 10 has a space reserved for the distal movement of the molars. That is, each stage of the brace 10 has a vacuole 13 on the distal side where the molars need to be pushed backward.

[0028] Attachments 14 are provided on the positions of the molars (adjacent teeth) on the mesial and distal sides of the denture 11 to reduce tooth rotation and tilting. Adhesive attachments 14 are provided on the labial side of the adjacent teeth to avoid unintended tilting and rotation of the adjacent teeth, assist in aligning the adjacent teeth, and help to form a good proximal relationship after the missing tooth restoration is completed. Attachments 14 are installed on the adjacent teeth and set inside the denture 10.

[0029] Annex 14 is preferably a tooth-limiting and fixing kit.

[0030] The above-mentioned technical solutions can reduce the number of orthodontic appliances in the patient's mouth during orthodontic treatment to widen edentulous spaces, improve the aesthetics of the teeth during the treatment process, shorten the chairside operation time for medical staff, and improve comfort.

[0031] 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.
