Abstract
The utility model relates to a multilayer composite zirconia corona dentis fixed bridge. The corona dentis fixed bridge comprises 2-16 conjoined or segmented half-bridge or full-bridge fixed dentures; corona dentis data is obtained through oral scanning of the corona dentis fixed bridge; the corona dentis fixed bridge is then processed into an inner crown through a numerical control machine tool; a composite layer which is made of a plurality of layers of porcelain cement and is in the shape of a tooth is arranged on the surface of the inner crown; the corona dentis fixed bridge is the same as a to-be-nested tooth in shape; and the corona dentis fixed bridge is bonded on abutment teeth through glue. According to the utility model, optical impression of the abutment tooth is obtained through an optical probe, the inner crown is formed through the numerical control machine tool, and 4-5 layers of porcelain cement is used to make teeth on the inner crown, so that the color and the appearance are very verisimilar, the corona dentis fixed bridge has high marginal adaptation to the abutment tooth, the possibility of secondary tooth decay is reduced, and the corona dentis fixed bridge has the advantages of extreme attractiveness, no metal restoration and high fastness; and zirconia ceramic has very good mechanical property and better bending strength and chemical stability, and the strength of the zirconia ceramic is not influenced by ageing.
Description
Technical field
This utility model belongs to tooth plantation recovery technique field, particularly relates to MULTILAYER COMPOSITE zirconium oxide corona fixed bridge.
Background technology
The large progress that implantation of tooth is known as and is attracted people's attention most on 20th century dentistry history also is one of stomatology field subject with fastest developing speed in recent years.At western developed country, implantation of tooth has obtained to popularize on a large scale and use.Metal current porcelain corona fixed bridge is comparatively general tooth implantation technology, but the manufacture method more complicated of Metal-porcelain corona fixed bridge, need through delivery, waxing, embedding casting, the operating process that Beijing enamel etc. are complicated, patient needs repeatedly outpatient service just can finish to plant tooth, and its biocompatibility is not fine, and the corona fixed bridge of making and the adaptation of abutment are not high enough, and color and form be shortcoming to some extent also.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of MULTILAYER COMPOSITE zirconium oxide corona fixed bridge, and biocompatibility, adaptation are not high enough to solve, the problem of color and form.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of MULTILAYER COMPOSITE zirconium oxide corona fixed bridge is provided, described corona fixed bridge comprises half-bridge or the full-bridge fixed denture of 2-16 disjunctors or segmentation, described corona fixed bridge obtains the corona data by the mouth interscan and is processed into interior hat through Digit Control Machine Tool again, the composite bed of making teeth patterning with some layers of porcelain powder on described interior hat surface, the shape of described corona fixed bridge is identical with the shape of required nested tooth, and described corona fixed bridge is bonded on the abutment by glue.
Described composite bed is composited by 4-5 layers of porcelain powder.
The material of described porcelain powder is zirconia ceramics.
The material of described porcelain powder is glass infiltration zirconia ceramics.
Described glue is resin-bonded glue.
Beneficial effect
This utility model compared with prior art, this artificial tooth obtains abutment optics die by optic probe, make hat in by Digit Control Machine Tool processing, then in the interior form of labeling the tooth of producing with 4-5 layer porcelain powder, so its color and form are very true to nature, high with the adaptation of abutment, reduce the probability that secondary decays tooth, also have in addition following advantages:
1, highly attractive in appearance, without metallic prosthetic.
2, as ep-type material, can not cause any anaphylaxis.
3, accurate adaptation, being preced with good marginal is the successful essential condition for the treatment of.
4, easy and simple to handle, traditional dummy manufacture method more complicated, this utility model is the mode of operation that Oral Repair has been broken away from tooth preparation, impression taking, filling die, made wax pattern, embedding casting, but with obtaining optics die input computer, design on computers again dummy, replace with Micro Milling Machine processing dummy at last, therefore reduced patient's medical number of times and the time.
5, firm, zirconia ceramics has good mechanical performance, and its bending strength and chemical stability are better, and intensity is not subjected to burn-in effects.

The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only are used for explanation this utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1 and Figure 2, this utility model provides a kind of MULTILAYER COMPOSITE zirconium oxide corona fixed bridge, described corona fixed bridge 1 comprises half-bridge or the full-bridge fixed denture of 2-16 disjunctors or segmentation, described corona fixed bridge 1 obtains the corona data by the mouth interscan and is processed into interior hat through Digit Control Machine Tool again, the composite bed of making teeth patterning with some layers of porcelain powder on described interior hat surface, the shape of described corona fixed bridge is identical with the shape of required nested tooth, and described corona fixed bridge is bonded on the abutment by glue.
The material of described porcelain powder is zirconia ceramics or is glass infiltration zirconia ceramics.Described glue is resin-bonded glue.
In disease population, place rubber dam, Abutment surface spraying developing powder, obtain abutment optics die with CEREC II type machine optic probe, the corona fixed bridge comprises half-bridge or the full-bridge fixed denture of 2-16 disjunctor or segmentation, make interior hat by Digit Control Machine Tool processing, then in the interior form of labeling the tooth of producing with 4-5 layer zirconium oxide porcelain powder, the corona fixed bridge adopts the resin adhesive bonding after transferring the He polishing.
