Description
Technical field
The present invention relates to orthodontic bracket and manufacture field, particularly relate to a kind of manufacture method of individual tongue-side straight arch wire self-ligating brackets.
Background technology
Along with the development of mouth cavity orthodontic technology and people improve gradually to requirement attractive in appearance, the stealthy correction in tongue side becomes the hot topic of orthodontics just gradually.Because bracket is positioned at the lip side of tooth in traditional lip side correction, affect the attractive in appearance of patient, make a lot of people therefore abandon orthodontic treatment.And lingual bracket appliance is positioned at the tongue side of tooth, can really realize complete stealth, meet the demand of much higher to aesthetic adult patient.
But because everyone the lingual surface form of tooth exists very big-difference, tradition lingual orthodontics device is made by manual plaster model row tooth, casting resin between bracket base and facing is needed to form personalized base plate, skilled worker room comparison trouble, easily come off, once again bonding also more difficult after coming off.
Traditional lingual bracket needs doctor to be that the bracket of every tooth and arch wire carry out ligation when clinical manipulation, tongue side due to tooth can supply the space of doctor's operation and the visual field very narrow and small, waste time and energy very much during ligation, adopt ligature ligation or elastic tape ligation can produce larger pressure to arch wire simultaneously, increase the frictional force between bracket groove structure and arch wire, the translational speed of the tooth that slows down.Along with popularizing of locking bracket, the clinical manipulation greatly facilitating doctor decreases the chair other operating time, and most locking bracket design needs to be undertaken welding by bracket base and supporter groove to form self-locking structure, but then relative complex is many to make self-locking structure on customized lingual brackets, base plate due to customized lingual brackets carries out personalized customization according to the facing of each patient, ensure that supporter groove is not easy with the accurate positioning of welding of base plate very much, this is also the reason that the producer of most of customized lingual brackets does not make self-locking structure.
In addition, on the arch wire of tongue side, the arch wire that tradition lingual bracket adopts is " mushroom " form, and in the Incognito Customized lingual appliance of 3M company and the Customized lingual appliance of Guangzhou Easthome, the arch wire of employing is the personalized arch wire along with bending along tooth tongue side.The arch wire of these two kinds of forms all can disturb the slip of bracket groove structure in arch wire above, and increasing friction force, is unfavorable for Tooth Movement, affects therapeutic efficiency.Along with the development of computer technology, rapid shaping technique, precision casting technology and precision welding technology, the lingual bracket appliance of personalized customization becomes the main flow of lingual orthodontic gradually.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of manufacture method of individual tongue-side straight arch wire self-ligating brackets, the individual tongue-side straight arch wire self-ligating brackets that the method makes has individual computer and designs and produces accurate positioning, the chair other operating time is short, self-locking structure doctor is without the need to spending extra time steel ligature, the arch wire design of tongue side raw silk rings is simultaneously convenient to steel wire and is free to slide minimizing frictional force in groove structure, is also convenient to doctor and carries out the advantages such as indivedual adjustment in the intense adjustment stage to arch wire.
