Description

Technical Field

[0001] The present application relates to the technical field of tooth correction devices, and in particular to a novel bonding type orthodontic advancement molar auxiliary device. Background Art

[0002] In the related art, the mandibular first molar is the first permanent tooth to erupt in the mouth, and its occlusal surface has deep pits and fissures, which are easily destroyed by dental pulp diseases such as caries, especially in childhood, due to poor oral hygiene maintenance and parents' mistaken belief that it is a replaceable deciduous tooth and no early dental pulp treatment, serious tooth damage occurs, making it impossible to retain it. Although more oral preventive health care methods have been popularized at this stage, there are still many mandibular first molars that need to be extracted due to dental pulp diseases in clinical practice. The loss of the mandibular first molar often leads to a series of complications such as: mesial tilting of the second or third molar, distal drift of the premolar, elongation of the opposing molar, absorption of the alveolar ridge in the edentulous area resulting in insufficient alveolar bone height and width, alveolar bone defects on the mesial side of the tilted molar, food impaction, and insufficient occlusal function in the edentulous area.

[0003] The mandibular first molar is essential for establishing a normal occlusion and exercising chewing function. It should be repaired in time after it is lost. Traditional restoration methods include fixed dentures, removable dentures and implant dentures. Fixed denture restoration requires tooth preparation of adjacent abutment teeth, which will cause certain damage to adjacent teeth and is less accepted by patients. Removable denture restoration has poor stability and low chewing efficiency. Long-term use will cause the abutment teeth to loosen and shift, and patients need to remove and clean them every day, which is inconvenient to use. Dental implants have certain requirements for the patient's alveolar bone conditions. If the height and width of the alveolar bone are not enough, implant restoration cannot be performed, and the scope of application is limited. The above three traditional restoration methods all have certain disadvantages. With the development and progress of orthodontic technology, the number of patients seeking orthodontic treatment to close the missing tooth gap is also increasing. In clinical practice, for some patients who come to the hospital for treatment due to the loss of the mandibular first molar, orthodontic treatment can be used to close the missing first molar gap. The advantage of this method is that after the orthodontic treatment, the patient does not need to add additional restorative treatment, which reduces the economic burden of the patient. Patients can use their own natural teeth. Compared with restoring an artificial tooth, their own natural teeth retain the vitality of the tooth body, pulp, and periodontal membrane. They have obvious advantages in biocompatibility, nerve sensation, anti-infection, and aesthetics. They have better chewing function and fewer postoperative complications. And for orthodontic patients, extracting a severely defective first molar that cannot be retained is more acceptable to patients than extracting a healthy premolar.

[0004] In the correction of the second molar moving mesially to replace the first molar after the loss of the mandibular first molar, the molar moves forward a lot and the molar root surface area is large, the periodontal tissue resistance increases, and a greater support strength is required. When the molar moves mesially, the molar tends to twist mesial-lingually to produce undesirable tooth movement. The mesial movement of the molar is usually difficult, and the traditional correction method is to choose to implant an implant as a support to move the molar forward.

[0005] However, implant support is often used clinically. The implant is placed in the predetermined position, and the buccal side is forced by a push spring, and the lingual side is forced by a lingual buckle to move the molar mesially. However, some patients cannot accept the invasive operation of implant screws, and implant screws are difficult to operate, and may cause implant screw breakage, loosening, peri-implantitis and other disadvantages.
