Technical Field

The invention relates to the technical field of tooth correction, in particular to a tooth orthodontic bonding substrate and a manufacturing method thereof, which are used for providing traction force for a correcting arch wire in tooth correction.

Background

Orthodontics (Orthodontics) are the correction of teeth and the relief of malocclusions. Orthodontics mainly researches the etiology and mechanism of malocclusion deformity, diagnoses, analyzes, prevents and treats the malocclusion deformity, and can achieve the effect of beautifying teeth.

Along with the increasing of aesthetic requirements of orthodontics correction of oral medical technology and patients, orthodontics correction is also slowly developed by movable brackets and buccal side fixed brackets, and various correction materials and modes such as ceramic brackets, self-ligating brackets, lingual side invisible brackets and bracket-free invisible correction are developed. More treatment options are provided according to the requirements of different doctors and patients on curative effect, aesthetic property and comfort.

The functional bracket is mainly characterized in that the orthodontic force for orthodontic teeth is mainly derived from the muscle force of the oromandibular system of a patient or lasting and soft orthodontic force. Most functional brackets belong to removable brackets, such as Twin-block brackets and Frankel brackets, but some functional brackets belong to fixed brackets, such as Forsus brackets and Herbst brackets. Compared with a removable bracket, the fixing bracket has the advantage of no need of depending on the matching of patients, and can better ensure the curative effect to a certain extent.

The removable bracket of the movable bracket comprises a snap ring, an adjacent hook, a base bracket, a correction spring and the like of the retention device. The patient can take off and wear the clothes by himself. At present, the oral cavity correction device is mostly used for breaking bad habits of the oral cavity, correcting certain simple malocclusion (occlusal deformity) or serving as an auxiliary device for fixed correction, and the application range is limited. )

The metal bracket is characterized in that the orthodontic bracket is adhered to the buccal side of the tooth surface through adhesive, and the orthodontic arch wire and the orthodontic bracket on the tooth exert force to further straighten the tooth. Such a tray cannot be removed by the patient himself. At present, the most widely used metal bracket in the world is the straight wire bracket (straight wire appliances), and the most doctors are used and the application is the most widely, so the correction function is more complete in all aspects.

The self-ligating bracket is the most advanced buccal side fixing bracket at present, and compared with the traditional non-self-ligating bracket, the self-ligating bracket can obviously reduce discomfort in the orthodontic process, prolong the time of the interval of the follow-up diagnosis, shorten the time of operation in the mouth during the visit, and is easier to clean and keep the oral hygiene. In addition, self-ligating brackets may also reduce drag on the teeth as they move, helping to more quickly level and align the teeth. Self-locking designs of various brands on the market are different, and the double-clip type self-locking bracket also has a special automatic protection function, so that the arch wire can be automatically released when orthodontic force is too large, the damage to teeth and the absorption of the root tips are avoided, and the health of the teeth and periodontal is better protected. The self-ligating bracket is made of two materials, namely metal and ceramic, and has the characteristics. The color of the ceramic self-locking is very close to that of the tooth, and the ceramic self-locking bracket is more beautiful than a metal self-locking bracket.

The ceramic material has a color close to that of natural teeth, so that the ceramic material is better in concealment when being stuck on the teeth, and the correction process is silently completed. Therefore, the orthodontic appliance is popular with adults and patients with high requirements on beauty, and becomes one of indispensable materials for orthodontic correction. However, the ceramic material has weak strength and is easy to break during treatment or removal, thereby affecting the treatment result. And the color and luster is easy to cause staining and discoloration because of bad oral hygiene maintenance habits of patients, which is a main problem. But with the advent of the new generation of microcrystalline ceramic materials, these past deficiencies have now been overcome. Under the prerequisite of guaranteeing holistic intensity, the volume of present high-end ceramic bracket material is littleer, and intensity is higher, still possesses advantages such as difficult dyeing, discolour and demolish easily simultaneously.

The tongue side invisible bracket tongue side invisible orthodontic technology is an advanced orthodontic technology which is developed in recent years internationally, brackets are all arranged on the tongue side of teeth for orthodontic treatment, and orthodontic marks cannot be seen on the appearance. The lingual correction technique started to appear in japan and the united states as early as the seven decades of the twentieth century, has been self-organized through many years of theoretical research and technical perfection, and is widely used in japan and the united states. The tongue side invisible correction technology is relatively mature in countries such as Europe and America and Japan, and has higher requirements on operation of doctors and higher technical difficulty.

The bracket-free invisible orthodontic treatment is a technology for completing the whole orthodontic treatment course by customizing a series of transparent brackets through a 3D (three-dimensional) computer technology. Compared with the traditional orthodontic method, the bracket-free invisible correction can be freely taken off and worn, so the advantages of cleanness, comfort and aesthetic degree of the oral cavity are obvious, but the bracket-free invisible correction needs high cooperation of patients (the daily wearing time needs more than 22 hours), if the bracket-free invisible correction cannot be worn according to the time requirement, the treatment course is prolonged, and the curative effect is greatly reduced. Therefore, the fixed orthodontic appliance has a certain gap in the aspects of treatment results, treatment indication application range and the like.

The metal collar stuck on the back teeth is called a ring. The side surface of the correcting arch wire is welded with a round, flat or square thin tube, the correcting arch wire can pass through the correcting arch wire, and the correcting arch wire also plays a role in supporting the arch wire, so that the force is transmitted to the posterior teeth, and the movement of the posterior teeth is controlled. The buccal tube is welded on the band ring to transfer the correcting force, and the buccal tube is equivalent to a bracket bonded with the anterior teeth. Buccal tubes have various shapes, and the upper jaw and the lower jaw are different, but generally a small drag hook is provided for dragging teeth.

The orthodontic band is a fixing device for fixing the orthodontic appliance, a metal lantern ring is adhered on the teeth, and the surface of the orthodontic band is adhered with an orthodontic accessory, so that the orthodontic force is transmitted to pull and move the teeth, the orthodontic band is in an annular band shape, and the orthodontic band is formed by forging processing, and has the defects of poor suitability, easiness in loosening and falling and poor torsion resistance; large volume, large contact with tooth surface, food impaction and difficult cleaning; the tooth body is required to be prepared, and the tooth tissue is damaged to easily cause dental caries; poor torsion resistance, poor transmission of correcting force, and inaccurate positions of traction and moving teeth; the correction time is prolonged, the use feeling of patients is poor, the clinical operation is complicated and the efficiency is low.
