Abstract
The present invention relates to a transfer system for a mouth care substance, such as tooth whitening substances. The present invention comprises a zonal material with certain yield points and certain thickness. When the transfer system abuts on a tooth, the zonal material can have permanent deformation under the condition of pressure which is lower than approximate 250000 pascal, and can be matched with the front surfaces of many teeth. The transfer system also comprises a mouth care substance applied to the zonal material. When the transfer system is placed on the surfaces of the teeth, the nursing substance contacts the surfaces to provide active constituents to the surfaces. The nursing substance also plays an adhesive function between the zonal material and each of the surfaces. The enough time during which the system can be fixed to a proper position causes the active constituents to act on the surfaces. The nursing substance has anti-extruding performance which is sufficient to bear positive force which is applied to deform the zonal material. When the zonal material is used for pressure application and deformation, the substance basically can not be extruded between the zonal material and each of the surfaces.

Invention field
The present invention relates to a kind of with oral care substance such as teeth whitening material Transfer system to oral cavity tissue, dental surface, a plurality of adjacent teeth or their combination; particularly relating to a kind of wherein oral care substance was protected in the fully long time; avoid etch, make the active component in the oral care substance that therapeutical effect can be provided.More specifically, the present invention relates to the disposable transmission system that can use outside dental hospital, such transmission system is inexpensive, and not noticeable, influences normal doings wearing Shi Buhui.
Background of invention
Prevailing Dental Hygienist apparatus is a toothbrush.The mechanism of toothbrush bristles helps to remove food particle and dental plaque etc.Usually toothbrush and toothpaste use together.Before nineteen fifty-five, typical toothpaste is made up of surfactant and abrasive material.The purpose of these products is the mechanisms that strengthen toothbrush.
Nineteen fifty-five, the toothpaste CREST (Procter﹠amp of fluoride has appearred having; Gamble Company ofCincinnati, OH), toothbrush and this fluoride dental cream combine to show it is the appropriate means that the fluoride therapeutical effect is delivered to dental surface.Subsequently, in toothpaste, added some other active component such as tartar controlling agent, further Dental Hygienist effect is provided.Consumer also turns to their attention the beauty treatment aspect of dental care, as orthodontics with brighten.
Transmission can provide the chemical substance of mouth care treatment effect already to succeed, and it also is rational that expectation obtains same successful cosmetic result by brushing teeth.For example, released and claimed the product that can make teeth whitening.Yet,, need long time of contact and tooth is effectively brightened, so can not produce tangible whitening effect by general brushing teeth because the admissible intensity of using for the oral cavity of chemical substance is low.Therefore, to brighten surely they tooth people and to the people of the effect disappointment of whitening toothpaste, the help of usually seeking help from the professional bleaches their tooth.
The professional teeth whitening process that the dentist provides generally has two big classes: method of whitening outside method of whitening and the hospital in the hospital.Brighten in the hospital and will go to a doctor several times, each all be worn on special (purpose) rubber barrier beginning in the mouth with preparation, the rubber barrier be used to prevent the bleached chemical agent normally hydrogen peroxide contact with oral soft tissue.Preparation rubber barrier is to patient not only misery but also expend time in patient's mouth.Yet, because the intensity of peroxide bleaches, so do not allow to use the rubber barrier.Therapeutic process in the hospital also can make tooth to the hot and cold sensitivity, and this method is very expensive.
Method of whitening difference outside the hospital, because patient can be in the long time, the chemical reagent lower with intensity is applied to bleach on its tooth, is generally one day each several hours, continues several weeks.Outside the hospital bleaching process usually require first dental hospital be assembled into each given patient special use apparatus.This apparatus is to manufacture the device that can accurately be assembled on the patients teeth, is used for a kind of bleach product is delivered to patient's teeth as the gel that contains urea/hydrogen peroxide complex.Patient oneself is responsible for using this apparatus as the device that transmits and keep, and measures and bleach is applied on the dental surface.
Because apparatus will reuse, it must be enough firm, repeats to shirk, cleans, inserts, installs and wears guaranteeing.Can cooperate well in order in repeated use, to keep, such apparatus should be have necessarily inflexible.As a result, the edge of this apparatus generally is inflexible, stimulates gingiva through regular meeting, and the wearer can obviously experience the thickness of this apparatus and discomfort.Usually, patient is avoiding using this apparatus during social again.
There is unspecialized program to come the interested people of whitening teeth to adopt now for the commercially available prod that use is buied from pharmacy.These commercially available prod provide kit, and it comprises a general apparatus and the container of bleaching gel is housed.Obviously attracting is that this program cost is lower.The major defect of the apparatus of this " being fit to a proprietary size " is to compare greatly with the apparatus of specialty preparation in apparatus inwall and interdental space.Therefore, contact, just need more bleaching gel in order to ensure bleaching gel and the tight of dental surface.And matching relatively poorly means that bleaching gel more loss is on gingiva, in the oral cavity, finally also can be swallowed.Commercially available this instrument, the same with specialized dispenser program outside the hospital, require the user cleaning and reuse this apparatus.Because general apparatus also is not suitable for each user, therefore they limited the doings of user in the oral cavity even bigger than the apparatus of configuration to a greater degree.
Authorized on November 19th, 1996 and disclose some problem of once attempting to remedy commercially available instrument in the United States Patent (USP) 5,575,654 of Fontenot.Fontenot has disclosed a kind of mouldable dental instruments of pre-packing, is adapted to fit on the very wide dental arch of different magnitude range, and the medicine and the bleach of scheduled volume can be housed in this apparatus.During use, from packing, take out this dental instruments, aim at the tooth edge, shift onto on the tooth along periodontal tissue's direction then, up to the whole surface of tray covered teeth with parallel mode.The main benefit of the device that Fontenot discloses is to have cancelled the utensil tool to measure and filler, and the handling problems after each the use.Yet, can be observed this device and also often exist huge and problem that match.
1994, authorized May 10 in people's such as Curtis the United States Patent (USP) 5,310,563 and disclosed another kind of solution.People such as Curtis have disclosed a kind of by being squeezed in the putty-like material that formalizes on the tooth.By to the mechanical engagement effect of sunk surface and by rubbing action with this material fix in position.Said composition has been wrapped up active component.Active component is moved to gel and dental surface from compositions, rather than directly contacts with them.Presumably, the required time of wearing can increase, and this is a significant adverse.
Need a kind of system commodity that transmit cheaply, it is for customized, and the material that active component is provided that minimum volume is housed is as brightening material, and it can fit contact on suitable dental surface, so that transmit the active component in this material rapidly.In addition, need a kind of device of small and exquisite containing active component, it can allow the wearer use this system when social activity, and can not influence wearer's speech and appearance.What is also needed is a kind of containment means, it can take care of one's teeth and brighten material not because of contacting by etch with saliva with the oral cavity inner surface.
