Abstract
The utility model relates to a multi-layer composite zirconia full crown. The multi-layer composite zirconia full crown is characterized in that the full crown is a single independent corona; the intraoral scanning is carried out on the full crown to obtain dental crown data; the dental crown data is machined into an inner crown through a numerically-controlled machine tool; the surface of the inner crown is a tooth-shaped composite layer made from a plurality of layers of zirconia porcelain powder; the shape of the full crown is as the same as that of the dental crown of single incisor tooth or canine tooth or grinding tooth; and the full crown is glued on the base tooth of human body by glue. According to the multi-layer composite zirconia full crown, an optical impression of the base tooth can be obtained by an optical probe, the inner crown is machined by the numerically-controlled machine tool, and the form of the tooth is produced on the inner crown by 4-5 layers of porcelain powder, so that the full crown is very vivid in color and form, high in marginal adaptation with the base tooth, less in the probability of subsequent tooth decay, very attractive in appearance, free from metal repair, and very high in solidness, and the zirconia ceramics is very good in mechanical property, so that the multi-layer composite zirconia full crown is better in bending strength and chemical stability, and the strength of the multi-layer composite zirconia full crown can not be influenced by ageing.
Description
Technical field
This utility model belongs to tooth plantation recovery technique field, particularly relates to MULTILAYER COMPOSITE zirconium oxide complete crown.
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.The metal current porcelain complete veneer crown is comparatively general tooth implantation technology, but the manufacture method more complicated of Metal-porcelain complete crown, 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 complete crown 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 complete crown, 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 complete crown is provided, described complete crown is single independent crown, described complete crown 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 zirconium oxide porcelain powder on described interior hat surface, the shape of the shape of described complete crown and single incisor or canine tooth or the corona of grinding one's teeth in sleep is identical, and described complete crown is bonded on the human body 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.

Fig. 3 is this utility model canine tooth complete crown schematic diagram.
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.
Shown in Fig. 1-3, this utility model is a kind of to provide a kind of MULTILAYER COMPOSITE zirconium oxide complete crown, described complete crown 1 is single independent crown, described complete crown 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 the shape of described complete crown and single incisor or canine tooth or the corona of grinding one's teeth in sleep is identical, and described complete crown 1 is bonded on the human body abutment by glue.Described composite bed is composited by 4-5 layers of porcelain powder.
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, make hat in 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, complete crown adopts the resin adhesive bonding after transferring the He polishing.
