Abstract
A kind of artificial tooth (6) comprises the shelly outer body (4) that is made of the ceramic material of firing fully, is provided with porcelain powder (5) at the intracavity of main body; This porcelain powder (5) part is fired, and therefore artificial tooth (6) is being pressed to tooth goods (1) so that still be sticking at the shape of tooth goods (1) during to the molding of porcelain powder.After this patternmaking process, artificial tooth (6) is fired, so that finish the sintering procedure of the porcelain powder (5) after the molding, then artificial tooth is embedded on the tooth goods.
Description
The present invention relates to the structure of artificial tooth, particularly relate to and having: the artificial tooth of corona, mosaics, facing or similar structures form, be a improvement, here with reference to the content of having quoted this application to disclosed structure among my International Patent Application PCT/AU91/00300.
In above-described my earlier application,, constitute an artificial tooth thus by with an insert location be bonded to the intracavity of a dentistry outer body shell and then the insert and the body shell of combination is mounted on the tooth short column goods that prepare.
Under the contrast, the present invention proposes a kind of artificial tooth (artificial tooth is defined as corona, mosaics, facing or analog here), it comprises an outer body that plays tooth or the effect of part tooth, this outer body finally is made into or is processed into part according to the profile of at least a portion tooth and be the form of shelly body, and said outer body is filled by the porcelain powder of partly firing at least in part.
Preparing artificial tooth of the present invention realizes by following step: the porcelain powder that the part in the shell of getting wet is fired; Then the shell that comprises the porcelain powder of partly firing is pressed on covering partially flexible, that have ad hoc structure that is positioned on the dental articles; Afterwards, pull down the porcelain powder implant that this outer body and its contained part are fired, and it is fired fully from dental articles; Then, the top of outer body and the insert of porcelain powder fix in position on dental articles of firing fully that it comprised.By the present invention, provide a kind of simple and easy technology of inlaying artificial tooth with the precision that dental articles cooperates fully.
Because the hardness of the porcelain that the hardness of artificial tooth skin or shell is fired greater than the part of the inside, therefore artificial tooth being pressed together on the shape of taking out the tooth post on the ready tooth is an operation that is easy to realize, particularly also is furnished with a rustless steel rack on short column.
Because will carry out part to the implant of shelly artificial tooth before installing on the short column fires, therefore and the porcelain powder of the deficient in stability of complete unfired compare, this just helps to keep the shape invariance of artificial tooth implant when the artificial tooth implant is got wet and be assemblied on the short column, if and during artificial tooth is mounted to dental articles, will use this implant the time, also help to make it shelly from artificial tooth be outside and throw off.
Insert is the rustless steel rack preferably, or the rack of other erosion-resisting extensile material.Rack is supporting ceramic material, and provides strong mechanical interlocked between porcelain and the rack by means of the oxide-bound material.
Use dental cement, packing material or binding agent that complete artificial tooth body is adhered on the ready tooth short column goods.
This artificial tooth can have many forms, comprising facing or the monoblock type cusp and the facing of whole corona, mosaics, makeup usefulness.
According to another aspect, the present invention can be described as a method of making artificial tooth, this method comprises the steps:
Constitute a shelly outer body that plays tooth or the effect of part tooth, finally constitute and handle this outer body according to the profile of at least a portion tooth, said outer body is filled by the porcelain powder at least in part, and it is carried out part fire.
This main body can be the ceramic products of a hot melt.
This insert can be the rustless steel rack.
According to another kind of method, can be the shelly corona or the analog of dental surgery delivery dimension complete molding within the specific limits, from numerous sizes, select the appropriate size that is suitable for remaining tooth.Determine the size of rack according to the size of tooth, thereby promptly can guarantee enough big intensity that the tooth short column goods of preparation are just slightly a little bit smaller than rack.With the partially filled corona of choosing of porcelain powder, and to its carry out the part fire.The porcelain powder that part in the corona is fired is got wet, and corona is pressed together on the rack that covers short column.In case pull down the corona for preparing from the rack that covers short column, just corona is fired, in sintering procedure, in the ceramic products that the part of corona is fired, can have, also can not have rack, corona is bonded on the short column of tooth the most at last.
With reference to the accompanying drawings, one embodiment of the present of invention are only described by means of example.Wherein:
Fig. 1 is the decomposing schematic representation according to artificial tooth corona of the present invention;
Fig. 2 is illustrated on ready tooth and the rack profile in a stage in the perfect mosaic process of the corona that forms Fig. 1;
Fig. 3 is illustrated in before final the firing, and before the corona that will finally fire is fixed to ready tooth and rack, from ready tooth with cover the profile of the corona that rack pulls down.
Fig. 1 represents a dental articles 1 in patient's jawbone 2, and it is the cylinder of making by means of the dentistry grinding technique of routine, and corona can be fixed to that this is hard, on the cylinder of health.
Determine the shape of porcelain corona shell 4, make its function that can imitate the disease-free state dermal tooth and profile.The porcelain powder 5 that part is fired places the inside of corona shell 4.Rustless steel rack 3 is in the centre of short column 1 and corona shell 4, rack 3 is attached on the porcelain powder 5 in the cavity that is contained in corona shell 4 by mechanical interlocking mode by means of the eyed structure of rack 3.Use will pack into the whole corona 6 of rustless steel rack 3, the porcelain powder of firing 5 and porcelain system corona shell 4 of conventional dental cement, packing material or binding agent to be bonded on the short column 1.
The flexibility of rustless steel (or other suitable material) rack 3 makes whole corona 6 flexible much bigger than the corona of making of routine techniques.Therefore, corona 6 seldom may lose efficacy.But because of the porcelain implant 5 of the corona shell 4 of this network structure and shelly is that interlocking is bonded, if ceramic products has damaged really, this network structure also helps to keep the unitary fixed of this ceramic products in place, can be not cracked, in patient's mouth, can not become flexible.
Therefore rustless steel rack 3 is thinner relatively, allows corona shell 4 relative thicker with ceramic products main body in the implant 5, thus fabulous aesthetic quality can be provided, with solid metal-cored on the situation of traditional corona of formation compare, approach the quality of dermal tooth more.
For further improving aesthetic quality, can stipulate for example outside enamel enamel coating, middle part dentine enamel coating and the opaque ceramic products in inside that surrounds rack 3 to the porcelain prepared material.
Any one method in the available various method constitutes and this integral body corona 6 is installed.The porcelain tooth of standard hat shell 4 can be made various sizes and shape, and the porcelain powder of firing with part to porcelain tooth be preced with shell 4 carry out partially filled, in dental surgery.Determine the shape of rustless steel rack 3, make its tooth goods 1 that are adapted to prepare, then rack 3 is inserted in the suitable corona shell 4 of making in advance that comprises porcelain powder 5, and then pull down and dry by the fire burning.This baking is burnt and refining step may only need about one hour, uses dental cement that supporting porcelain shell is bonded on rack 3 and the tooth goods (short column) 1 then.So, only remove dental surgery one time, just can inlay high-quality, a nonvolatil corona.
According to the method that employs one's time to the best advantage, can be in dental laboratory at each tooth make various size, comprise part and fire porcelain tooth hat shell 4 porcelain powder 5, complete, that fire fully.The size of rack 3 that is identified for porcelain tooth hat shell 4 according to the external dimensions of porcelain tooth hat shell 4 is so that guarantee have enough big porcelain thickness to gain in strength, but also will leave cavity that to the greatest extent can be big so that can be mounted on the big as far as possible tooth goods short column 1.In dental surgery, the suitably porcelain tooth hat shell 4 of size is selected by odontologist, and short column 1 is made suitable size.To get wet through the porcelain powder 5 that part is fired, on rack 3, porcelain tooth hat shell 4 be pressed to short column 1.After pulling down porcelain tooth hat shell 4, porcelain tooth hat shell 4 is fully fired, so that fix the shape of porcelain powder 5, again porcelain tooth is preced with shell 4 at last and is fixed on the short column 1 via intermediary rack 3 with respect to the shape of the rack on the short column 13.
The implant material is plastics, or pastel and so on, and it is filled in any space between rack 3 and short column 1.Implant will be solidified after 5 minutes generally speaking, and this work promptly declares to be finished.
Therefore, the actual shape of the dermal tooth of that patient needs in order to copy satisfactorily, the cheap succedaneum identical with dermal tooth intensity, patient can select, so that obtain the corona of a shape of oneself being accustomed to.Under any circumstance, the mechanical performance of this corona all is better than the corona of prior art.
It will be apparent to the person skilled in the art that under the situation of not leaving generalized design of the present invention and scope, can make various variations and/or improvement the present invention who describes in these specific embodiments.Therefore, these embodiment are considered in all respects in order to describe, rather than in order to limit the invention.
