Background
Orthodontics is the correction of misaligned teeth by applying corrective forces between the teeth using corrective appliances to the teeth. At present, most of common orthodontic methods are to install a fixed bracket on each tooth and to correct the tooth by means of force application through a correction arch wire.
During orthodontic correction, most patients require the molar to move in three dimensions. When the molar teeth are locked, the teeth are expected to move labially/lingually; when the molar relationship is class II/class III, it is desirable that the molar be able to move sagittal; when the molar is elongated, it is desirable that the molar be able to move in a vertical direction. However, since the molar is located at the rear of the dental arch, the function of the orthodontic archwire cannot be fully expressed, the three-dimensional direction of the molar is not well controlled, and some orthodontic devices are often needed to assist in regulating and controlling the three-dimensional movement of the molar.
The existing effective means is mainly to implant micro-implant nails at the corresponding parts of alveolar bones to provide anchorage so as to obtain the desired tooth movement and avoid the undesired tooth movement. The implantation of the micro-implant nail is an invasive and invasive treatment mode, and has the risks of local inflammation, falling off, breaking off and the like; meanwhile, the method has corresponding requirements on the age and the anatomical structure of patients, and not all patients have the conditions for implantation of micro-implant nails, and the method is not suitable for the cases of too low maxillary sinus floor, immature alveolar bone development, unclosed apical foramen and the like.
In addition to micro-implant nails, there are other adjunctive therapeutic devices such as palatal rods, Nance palatal braces, and the like. However, these devices have significant limitations, such as most devices are capable of only one dimension of tooth movement; the lower jaw auxiliary device is difficult to design and manufacture; compared with the CAD/CAM technology, the arch wire bending or casting mode is adopted, the precision and the strength are not good enough, and the integrated manufacturing is not realized.
