Technical field
The present invention relates to be used for the photosensitive tooth goods and the luminous tooth dishwashing on dental treatments surface.Specifically, The present invention be directed to some tooth goods of picture dental bleaching goods and so on, these tooth goods with the container of depositing the tooth goods is housed is placed on and wants the luminous dental tray of dental treatments near surface to be used.
Background technology
Pure white because of smoking or taking in that food loses white naturally or the tooth of obfuscation is more and more universal gradually.People are not that the peace facing is put frosting exactly on tooth for functions of whitening teeth in the past, and these two kinds of functions of whitening teeth methods must be done costliness and complicated tooth operation.Recently, the chemical bleaching of tooth make people can be pure white they tooth and these both expensive complicated teeth operations before it goes without doing.
In some method for bleaching, hope has the tooth patients of their tooth that bleaches must use conventional dental bleaching technology method in early days.These technical methods involve and put into peroxide solutions on teeth, heat or irradiation with the soft tissue of ligation rubber sealing ring protection sensitivity with to solution.Regrettably, be to dry up the only high power high voltage light that tooth uses in dental operation, so cause more serious postoperative allergy.In addition, such a dental procedure is very time-consuming when patients generally need a plurality of positions significantly to change color.The needs of paying a home visit for multi-door training cause expensive operation.Although expense and some other problem have a relation with the industry that cleans one's teeth, these professional methods mainly with only belong to cheek or oral area, only be the pure white relevant of positive top layer.
Because consumed time is paid a home visit similar with these dentistry and expense is relevant therewith, so full of interest to pure white product of household tooth and method thereof in the industry at tooth.Wherein a kind of early stage home method needs the alginate impression of a kind of cacodontia of specialize; Do a kind of impression foundry goods; Make a kind of pallet and remove gums cover layer finishing impression with the foundry goods vacuum.In using early stage housed device and method thereof, the patient of church puts into several liquid lime chlorides and is used in each each zone of the pallet of wanting bleaching teeth, and some excessive liquid lime chlorides are put into the pallet that fills liquid lime chloride in the mouth and spue.Regrettably, use such equipment and method to require the patient to change liquid lime chloride in per 1 to 2.5 hour, and will unload dental tray when being at table.Therefore, this domestic are expensive, time-consuming, trouble and need stand the misery that lacks the matching property flexibility.
Because so both inconvenient and expensive home method, so had various bleach immersion as the liner of fiber or fabric strip and so on so that the patient is attached to liner more novel home method on their tooth in the bedtime.A kind of known home method is used as the tooth bleaching agent to the various peroxide in the gel foam material.Most of general tooth bleaching agent is 10% urea peroxide (CN (NH
2)
2H
2O
2), urea peroxide is also referred to as urea hydrogen peroxide, hydrogen peroxide phosphoamide and perhydrol carbamide.
Though some effective results tested with foregoing domestic technical method, their usefulness depends on some factors the effective ingredient amount that is suitable for to a great extent in the type of tooth enamel stain and density, bleach time of contact and bleach.Yet advantage is to spend in tooth clinic outside actual bleaching promised time of the course of treatment.Thereby the expense of these domestic operations is less than conventional clinic bleaching technology method basically.
Regrettably, although some improvement are being arranged aspect these home method, concerning the domestic bleach product, also have some shortcomings and limitation.A remarkable shortcoming in more known home method is with needed very long application time of these methods or very long time of contact.Because the time of contact of rectificating, so during sticking, must change continually or the post-bleach agent.So reduce rapidly and need to replenish because the saliva dilution of bleach and swallowing makes tooth stick in the pallet the overtime ground of the volume of bleach.Many-sided bleach volume that had in sticking pallet later on originally in a hour that studies show that is less than half.Thereby, concerning existing bleach,, therefore additional for effective force needs of about each hour owing to their applying method and the time of contact that needs length.
Because constantly change the inconvenience and the needed long time of contact of bleach, some home method obtain highly successful not as full-time bleaching technology in the clinic like that so patient's conformability is difficult to keep.
The another one problem of existing domestic bleaching goods and using method thereof is usually to stick just can see desirable effect in several weeks.Though the certain methods propaganda makes tooth shinny in the shorter time cycle, the remarkable result of domestic bleaching needs roughly 4～6 week.If not all so also be that tediously long processing cycle and conformability problem make us dissatisfied under the situation of many existing household article and method.
So should be appreciated that some goods and method need anything what just improves technically for faster and dental treatments surface more effectively, more patient become more cooperate and feel more satisfied.Therefore, for fast-acting being provided, not needing continuous replacing, being used for the tooth bleaching goods on dental treatments surface thereby improving patient's conformability, will be a much progress technically.
Therefore need and a kind ofly will make the obfuscation dental bleaching and prevent the tooth jaundice and do not need the teeth whitening method of complexity, time-consuming and expensive equipment.
