Description

Technical Field

[0001] The utility model relates to the field of retainers, in particular to a Harry retainer which can be repeatedly disassembled and assembled. Background Art

[0002] Retainers are measures taken to consolidate the therapeutic effect of malocclusion correction and to keep the teeth in an ideal aesthetic and functional position. This is called retention, and the device worn at this time is called a retainer. After the teeth are corrected and the appliance is removed, because the teeth are not yet stable in the new position, retainers are often worn to maintain the new position of the teeth on the alveolar bone. Harry retainer is a removable retainer. During the use of the existing Harry retainer, the foreign body sensation will be more obvious when worn, and there is a steel wire across the front teeth area, which is not easy to disassemble, which can easily affect the patient's daily comfort and reduce the overall use effect. Therefore, we propose a Harry retainer that can be repeatedly disassembled and assembled to solve the above-mentioned problems. Utility Model Content

[0005] Preferably, the retainer module is connected with the tooth adjustment module and the installation module is connected to maintain the overall flatness. The plaster tooth model can be modified and adjusted according to the size to better fit the single tooth model. The external plug-in base and the internal plug-in base can form internal and external double protection. The first flexible membrane and the second flexible membrane form flexible support protection to avoid breakage in the oral cavity, which greatly improves the patient's comfort in daily life. The reinforcement rod sleeve is used to store the steel wire to form reinforcement protection and improve the overall use effect.

[0006] Preferably, the installation module includes a shock-absorbing plate, a support platform, an adjustment sliding bin and a socket area. The support platform is provided at the upper end of the shock-absorbing plate, and an adjustment sliding bin for installing a correction tool is provided in the middle of the support platform. The periphery of the adjustment sliding bin is provided with a socket area for placing the tooth adjustment module. The overall support operation can be maintained through the support platform.

[0007] Preferably, the tooth adjustment module includes a U-shaped tooth model sleeve, an air bag layer and a plug-in bin. The bottom of the U-shaped tooth model sleeve is provided with an air bag layer, and a plug-in bin is provided along the center edge of the U-shaped tooth model sleeve. A gap groove for connecting and positioning is provided between the two groups of plug-in bins, and different gypsum tooth models can be placed in sequence through the plug-in bins.

[0008] Preferably, the retainer module includes an external plug-in base, an internal plug-in base, a toggle button, a first flexible membrane, a second flexible membrane, a molar clasp, a tensioning area, a reinforcement rod sleeve and a hyperbolic lip bow.

[0010] Preferably, a tensioning area for adapting a single tooth for correction and for filling materials is formed between the outer plug-in base and the inner plug-in base. The material can be filled in the tensioning area to reduce the gap between the outer plug-in base and the inner plug-in base.

[0011] Preferably, molar clasps are symmetrically provided at one end of the outer plug-in base and the inner plug-in base, and a reinforcing rod sleeve is provided on the outer side of the molar clasp.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, there were steel wires across the front teeth area, which were not easy to disassemble, and easily affected the patient's daily comfort, reducing the overall use effect. What is different is that by selecting a tooth adjustment module, you can install single plaster models of different teeth in the plug-in bin in turn according to the different sizes of each person's teeth. Use the retainer module to connect with the tooth adjustment module set, and fit the installation module to maintain the overall flatness. You can make corrections and adjustments according to the size of the plaster tooth model to make it better fit the single tooth model. Use the external plug-in base and the internal plug-in base to form internal and external double protection. The first flexible membrane and the second flexible membrane form a flexible support protection to avoid breakage in the oral cavity, greatly improving the patient's daily comfort. Simultaneously, use the reinforcement rod sleeve to store the steel wire to form reinforcement protection and improve the overall use effect.

[0014] 2. When disassembly and adjustment is required, you only need to adjust the toggle button to open the external base and the internal base in turn. The disassembly and installation operations can also be performed, so that it can be adjusted repeatedly to improve the overall operating performance. The material is light, does not affect the patient's daily life, has a good fixing effect, and prevents tooth displacement. BRIEF DESCRIPTION OF THE DRAWINGS
