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, toothpaste CREST (the 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.
Summary of the invention

Fig. 5 and shown in Figure 6 be that the present invention that oral care substance is applied to tooth or a plurality of adjacent teeth surface is transmitted system 24.Be embedded in the adjacent soft tissue 20 is tooth 22.Tooth 22 is defined as the part of a tooth, single tooth or one group of adjacent teeth herein.For example Figure 6 shows that one group of adjacent tooth.Adjacent soft tissue is defined as the tissue surface around tooth structure herein: comprise edge gingiva, gingival sulcus, interior gingiva, gum tongue and the lip-deep gingiva anatomy of gum cheek, press from both sides (pallet) up to comprising mucus gingiva connecting portion and pitching.
Among Fig. 5 and Fig. 6, transmission system 24 is represented strip material 12 and material 14, and it is material 14 that strip material 12 is faced on the face of tooth 22.Material 14 can be coated with in advance by the user that transmits system and be applied on the strip material 12, perhaps is applied directly on the tooth 22, then with strip material 12 coverings.In both cases, the yield point of strip material 12 and thickness can both make its permanent deformation under approximately less than 250,000 pascal pressures, and is good fit with tooth 22 and adjacent soft tissue.Strip material has certain viscoelasticity preferably, thus can produce creep and bending, can be on several teeth and in the wearer oral cavity on arcus dentalis inferior cooperate.Importantly apply under the very little positive force this permanent deformation will take place by the wearer.Strip material is fitted on the contour surface and contiguous soft tissue 20 of tooth 22 with hands, uses very little power, can be surperficial and be connected between the soft tissue 20 and obviously extrude from strip material 12 and tooth 22 so as not to material 14." obviously extrude " be meant at least 50% or more material 14 from strip material 12 with tooth be close between the soft tissue surfaces and squeezed.
Have been found that the wearer presses to each tooth so that about 1 centimetre of 2 contact surface is long-pending with the material band with a finger.Usually on each tooth, exerted pressure one second or shorter.Generally the scope of exerting pressure is about 100,000-250,000 Pascal.
The effect of strip material is as a protection barrier, and it can prevent obviously that wearer's lip, tongue, other soft tissue and saliva are to material 14 generation leaching and/or erosions.The time lengthening that acts on dental surface for the active component that makes in the oral care substance extends to several hours from a few minutes, importantly will reduce this leaching and/or etch as far as possible.Herein " effect " be defined as the variation that generation needs.For example, if this material is a peroxide, it should be able to reach whitening effect by the interior chromoplast of bleaching teeth; If active component is a sodium fluoride, it should be able to promote to form fluorophosphate on enamel substrate, and the solubility in acid of enamel substrate is reduced.
By the sticking action that material 14 provides, strip material 12 is fixed on the tooth 22.The viscosity of material 14 and whole viscosity can make strip material 12 viscosity be fixed on the tooth 22, when move in oral cavities such as the wearer speaks, drinking-water, at lip and tongue and other soft tissue and strip material 12 relative operations under the possible rubbing action that causes, strip material can not slided basically.
Fig. 7 and shown in Figure 8 be that transmission system 26 of the present invention is applied to tooth 22 and adjacent soft tissue 20 lip-deep situations.Transmission system 26 is represented strip material 12 and material 14, material 14 be in strip material 12 on the one side of adjacent teeth 22 and adjacent soft tissue 20.Although strip material 26 does not have viscosity to be fixed on the adjacent soft tissue 20, it can keep the location because of viscosity is fixed on the tooth 22.
In the preferred embodiment of the present invention, material 14 is tooth whitening gels of a kind of 30-85% of containing glycerol or Polyethylene Glycol, 10-22% urea/hydrogen peroxide complex, 0-12% carboxyl polymethylene, 0-1% sodium hydroxide, 0-10% triethanolamine (TEA), 0-40% water, 0-1% flavoring agent, 0-15% Fructus Citri Limoniae sodium and 0-5% ethylenediaminetetraacetic acid.The viscosity of gel under low shear rate (less than l/ second) is at 200-1 preferably, 000,000 centipoise scope.Better brightener for tooth is the gel that contains 70% glycerol, 5% carboxyl polymethylene, 10% urea peroxide, 15% water, and regulating its pH with sodium hydroxide is 6.5.This prescription possesses enough anti-extrusion performances, on strip material, apply the teeth whitening material coating of 0.25 millimeters thick, less than 133, with hands strip material is pressed in when strip material distortion is cooperated with tooth under 000 pascal pressure, the teeth whitening material from the amount extruded between strip material and the dental surface less than 50%.Commercially available brightener for tooth such as Opalescence and Nu-Pro Gold also can be used for transmission system of the present invention.
The oral care product of another kind of available transmission system operation of the present invention is the fluoride topical gel, and its viscosity is similar to the gel in the preferred embodiment that the part applies the fluoride caries prevention.
The gross thickness of transmission system generally should be less than about 1.5 millimeters.The thickness that material is 14 layers is about 0.4 millimeter for good.
Be preferably, use transmission system of the present invention that the teeth whitening material is applied to tooth last 120 minute continuously, once a day, after about 7-14 days, the whitening effect that can reach the raising of 1-4 colour code is (with VITA LUMEN VacuumFarbskala colour code instrumentation amount, it is VITA Zahnfabrik, of BadSackingen, the product of Germany).
To oral care product such as Luride Gel, use transmission system of the present invention, gel is applied on tooth and/or the adjacent soft tissue about 4 minutes continuously, annual, help to prevent dental caries.
When the wearer when tooth and adjacent soft tissue are taken off strip material of the present invention, can be on tooth and soft tissue surfaces more residual materials.Brush teeth or just clean and easily to remove these residuals.
Though illustrate and described specific embodiments more of the present invention, those skilled in the art should be understood that, can carry out various changes and modification under the situation without departing from the spirit and scope of the present invention, claims have been intended to cover all modifications in the scope of the invention.
