Description

TECHNICAL FIELD

[0001] The utility model relates to orthodontic technical field, specifically, relate to a kind of invisible appliance for easy correction lock . BACKGROUND

[0002] malocclusion It is a common oral disease, its main performance is that teeth are not neat, Relationship is abnormal, jaw relationship is abnormal etc. Lock It is a common malocclusion, Also called cross , often occurs in the free end of dental arch final section (second molar), performance is that upper and lower jaw individual tooth is not occluded, Face is not contacted. Second molar lock Can be performance is positive lock , maxillary second molar is mispositioned buccally, mandibular second molar is mispositioned lingually, or reverse lock , maxillary second molar is mispositioned palatally, mandibular second molar is mispositioned buccally, wherein the performance of positive lock Most. The type of malocclusion can cause different degrees of Interference, After upper and lower teeth occlusion, mandibular bone is displaced, and lock Occurring in upper and lower second molars has different degrees of temporomandibular joint disorder symptoms, which affects the oral health, function and quality of life of patients.

[0003] At present, the correction of second molar lock Usually has the following ways. First, adopt upper and lower teeth interactive traction, so that it Face has contact. The correction method is relatively convenient, but easy to cause and aggravate lock Vertical problem, hinder build . Second, adopt the way of micro-implant anchorage nail auxiliary, implant micro-implant anchorage nail on the palatal side (buccal side) of maxillary second molar mispositioned buccally (palatally) and the buccal side (lingual side) of mandibular second molar mispositioned lingually (buccally), respectively on maxillary lock Tooth and mandibular lock Orthodontic traction is used to prevent elongation. This method is commonly used, but there is a certain probability of anchorage screws loosening and falling out during treatment, or the anchorage screws need to be repositioned according to tooth movement and response as the treatment progresses. This requires the patient to pay related fees again, creating a financial burden, and may also affect the health of the periodontal tissues, alveolar bone, and roots of adjacent teeth around the anchorage screw, potentially causing inflammation and affecting the patient's oral health. Third, removable appliances are used for treatment. Hooks are designed on the palatal (buccal) side of the maxillary second molar in buccal (palatal) misalignment and on the buccal (lingual) side of the mandibular second molar in lingual (buccal) misalignment, followed by traction. However, the removable appliances used in this method may affect patient comfort due to their large size, and poor retention may affect treatment progress and cause discomfort. In addition, neither the use of micro-implant anchorage screws nor removable appliances has been able to open the posterior occlusion to further correct the second molar lock. Providing vertical space may increase the probability of treatment failure due to insufficient vertical height. Utility Model Content

[0004] This utility model provides a convenient orthopedic lock Invisible braces to correct existing misalignments During orthodontic treatment, it is difficult to further correct the second molar lock. Providing vertical space can lead to insufficient vertical height, increasing the risk of treatment failure.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A type of easy-to-correct lock The invisible aligner includes an upper aligner, a lower aligner, and a latch for fixing the second molar to the side away from the gum. Both the upper and lower aligners are provided with cantilever arms, which are located on the side of the second molar away from the latch. The cantilever arms and latches on both sides of the same second molar are connected by elastic elements.

[0007] This invention uses maxillary and mandibular braces as locks for the second molars. The system provides vertical space and then uses the elastic element to traction the second molar. Since the lock and cantilever are located on both sides of the second molar, the elastic element spans the second molar and presses the second molar towards the gum line, thus providing vertical space.

[0008] Furthermore, a first groove is formed on the side of the cantilever end away from the latch. The first groove limits one end of the elastic element and provides tension to the elastic element.

[0009] Further, the cantilever is provided with a reinforcing ridge on the side away from the lock catch. In order to prevent the upper dental brace and the lower dental brace from damaging the teeth and the gums, the upper dental brace and the lower dental brace are usually made of soft material, and therefore the reinforcing ridge is arranged to enhance the bending resistance of the reinforcing ridge and reduce the possibility of the reinforcing ridge pressing the gums.

[0010] Further, the length of the reinforcing ridge is greater than the length of the cantilever, so as to enhance the bending resistance of the cantilever as much as possible.

[0011] Further, the reinforcing ridge is located at the middle of the cantilever, so that the bending resistance of the two sides of the reinforcing ridge is equal, and the cantilever is prevented from deflecting to one side of the reinforcing ridge under the pulling force of the elastic member.

[0012] Further, the upper dental brace and the lower dental brace are provided with a plurality of second grooves on the inner sides, and the adhesive member is matched with the second grooves.

[0013] Similarly, due to the inherent shape of the teeth and the gums, the upper dental brace and the lower dental brace may not be well fixed, and therefore the part of the upper dental brace and the lower dental brace that is sleeved on the first molar is prone to deformation under the pulling force of the elastic member, so that the upper dental brace or the lower dental brace is deformed and separated from the teeth, and the correction ability of the second molar is reduced. Therefore, the adhesive member fixed to the teeth is matched with the second grooves, so as to provide a limit for the upper dental brace and the lower dental brace, and reduce the possibility of the upper dental brace and the lower dental brace being pulled away from the teeth by the elastic member.

[0014] Further, the second grooves are located on the side where the cantilever is located.

[0015] Further, the adhesive member is matched with the second grooves one by one.

[0016] Further, the elastic member is a rubber band.

[0017] Further, the upper dental brace and the lower dental brace both cover the first molar.

[0018] The one or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0019] (1) The upper dental brace and the lower dental brace are used for locking the second molar The elastic member is used for pulling the second molar, and the lock catch and the cantilever are located on the two sides of the second molar, so that the elastic member crosses the second molar and generates a downward pressing force on the second molar, and the second molar is pressed towards the gums, so as to provide a vertical space.

[0020] (2) The reinforcing ridge is arranged to enhance the bending resistance of the reinforcing ridge and reduce the possibility of the reinforcing ridge pressing the gums.

[0021] (3) through the fixed to the tooth on the adhesive piece and the second groove matching way, for the upper jaw, lower jaw tooth cover provides a limit, reduce the possibility of being pulled out of the tooth by the elastic element. BRIEF DESCRIPTION OF DRAWINGS
