Description
Technical field
The present invention relates to the orthodontic field.
Background technology
Traditional corrigent method of abnormal tooth is to let patient wear so-called " tooth set ".Tooth set by bracket, arch wire, tie up the device that rope and O shape circle are formed.In the process of traditional orthodontics, before tooth set being fixed on patient's tooth, use weak acid dental treatments surface, purpose is to improve the adhesive property of dental surface, so that bracket and garter spring are bonded in dental surface.After the acidify, the doctor is fixed on bracket and garter spring on the patient's tooth through the binding material that is fit to.After binding agent is fixing, force application apparatus---arch wire is installed again.
Arch wire is the main force application apparatus of traditional tooth set.The arch wire high resilience is fixed on the bracket through the groove on the bracket.Arch wire couples together many brackets, and constantly bracket is applied power so that tooth moves.Reverse steel wire or plastics O shape circle usually as strengthening arch wire fixing on bracket.In just abnormal technology, be fixed on arch wire that often to call on the bracket be " colligation ", tinsel is called " tying up rope ", and plastics O shape circle is called " working of plastics ".
After arch wire was in place, the patient still needed regularly to arrive just abnormal doctor's there further consultation, and the adjustment tooth set is for example changed the arch wire with different application of force performances, changes or tighten up the existing rope of tying up.Usually, every 3-6 week is carried out a further consultation.Concerning the patient, this traditional just abnormal rectifying effect is fine, but has some problems: the doctor is difficult to guarantee that fully according to the fixing bracket of visual sense feeling the position of bracket is ideal as expecting; Bracket is exposed to the outside, influences the attractive in appearance of patient; The contact surface of tooth set and tooth lacks effective health measure because be difficult to for a long time clean, and causes dental caries easily, oral cavity or periodontal infection; Further consultation is repeatedly changed arch wire or is tied up rope, has not only increased patient's expense, also lets the patient feel uncomfortable.
Therefore, people constantly attempt changing a kind of antidote of more science.As (1996) such as Kuroda in Am.J.Orthodontics110:365-369, described a kind of with laser scanning tooth jaw Gypsum Fibrosum to produce the method for tooth jaw digital picture, also see U.S. Pat 5605459.The U.S. Pat 5533895 of Ormco company, US5474448, US5454717, US5447432, US5431562 etc. have described the method for utilizing digital teeth graphical design dental appliance.
U.S. Pat 5011405 has been described in the orthodontic treatment and has been shown teeth images with numeral, and confirms the method for best located for bracket.Patent US5338198 has described the method for laser scanning tooth model generation threedimensional model.U.S. Pat 5452219 has been described with laser scanning tooth model and the method for grinding tooth model.U.S. Pat 5607305 and US5587912 have described the method for computer digital dental treatments profile.U.S. Pat 5342202 and US5340309 have introduced the method for Computer Processing tooth jaw digital picture.
U.S. Pat 6398548 has been described with computer program predicted teeth moving from the original position to the final position with US6554611; Design and make a series of different geometries that have; Realization is with the system of again arranging of tooth from the original position to the final position, and the user begins to finish to use a whole set of transparent stealth can pluck the apparatus that unloads to treatment from treatment.These apparatuses use in order by numbering or labelling.If but some tooth moves and does not reach desired location, can cause the difference of tooth physical location and desired location further to increase, like this, can produce asymmetric power, thereby increase the painful and uncomfortable of patient with respect to other teeth.In addition, cryptomorphic appliance is with high molecule plastic material preparation, and this type material has enough elasticity, but rescue strength a little less than, and in the reusable process of patient usually because aging and become lax, make corrective force loss.Therefore they only are suitable for the state of an illness and slightly, only need the faint case that strength just can realize that tooth is reset of rescuing.Present stealthy plastics appliance is mainly used in beauty therapeutic, but can't be widely used in orthodontic treatment.And stealthy plastics facing, because facing adopts the high molecule plastic material to process, hardness is relatively poor, and is excessive if facing moves the distance of tooth, not only can not play good rectifying effect, and can make the patient feel very uncomfortable.Therefore, when rescuing design, every secondary facing can only be designed so that tooth moves in smaller distance, and the whole treatment system rescues with regard to a large amount of single width facings of needs, and the cost of whole treatment has just improved, and the patient has been constituted very big financial burden.
Removable appliance is also claimed removable appliance, is that one type of patient can freely pluck the apparatus for correcting of wearing, and is made up of fixing device, force application apparatus and connecting device three parts.Fixing device commonly used has snap ring and embrasure hook; Force application apparatus commonly used mainly is a spring, for example hyperbolic tongue, hyperbolic lip bow, expansion bow spring and guide plate; Connecting device normally plastic base constitutes, and some then is made up of palate bar and hyoid arch.Common removable appliance is seen Fig. 1-4.These appliances usually can cause patient's dysphonia, and foreign body sensation is arranged, and the patient often is difficult to adhere to wearing.If but the patient can not partner treatment, can not adhere to wearing usefulness, just therapeutic effect can not get guaranteeing, finally cause the tooth original position of under orthodontic treatment, rebounding/recur, greatly reduced the just abnormal curative effect of using this removable apparatus.
Therefore, need be a kind of both attractive in appearance, patient's comfort can be do not influenced again, and quick treatment can be reached, shorten and treat the course of treatment, reduce the facing cost of manufacture, reduce the orthodontic system of patient economy burden.
