A kind of interior hat of baking-ceramic toothTechnical field
The utility model belongs to baking-ceramic tooth technical field, and in particular to a kind of interior hat of baking-ceramic tooth.
Background technique
Baking-ceramic tooth is since clinical application, due to its good biocompatibility, abrasion and corrosion resistance and natural in colorThe advantages that true to nature, it has also become treat the main method of anodontia.Dentistry cochrome is free of the nickel being harmful to the human body due to itElement and beryllium element are not easy allergy, are used oral cavity field extensively.Dentistry cobalt chromium alloy porcelain tooth compares nickel chromium triangle baking-ceramic tooth,The phenomenon that corrosion resistance is higher, biocompatibility is more preferable, is less prone to black gum or bleeding gums, safe and reliable and priceLower, gradually substituting nichrome baking-ceramic tooth becomes the first choice of base metal porcelain.
Baking-ceramic tooth full name is porcelain melting metal crown, is a kind of ideal dummy.First Metal Substrate is made with alloy in itBottom, then cover similar with natural teeth low fusing porcelain powder on its surface, be sintered in vacuum high-temperature porcelain furnace melt it is attached form, thus haveThe intensity of metal and the beauty of porcelain complete veneer crown.Its feature is that the morphological function that can restore tooth body, fracture resistence force be strong and color, appearanceIt is true to nature, surface is smooth, wearability will not deform by force, color stability, acid and alkali-resistance, belong to definitive prosthesis.
But the corona of existing baking-ceramic tooth is in the production process since that there are interior hat intensity is poor, holds for the factors such as production technologyThe problems such as enamel coating bursts apart easily occurs.
Utility model content
The purpose of this utility model is that: hat in a kind of baking-ceramic tooth is provided, solves in existing baking-ceramic tooth that hat intensity is poor, holdsThe problem of enamel coating bursts apart easily occurs.
The technical solution adopted in the utility model is as follows:
A kind of interior hat of baking-ceramic tooth, including interior hat, the interior hat bottom are provided with metal edges, and the metal edges are along interior hat bottomOuter rim track is uniformly arranged, and the height of the metal edges is 0.9-1.1mm, and the width of the metal edges is 0.45-0.55mm.
Further, the metal edges and interior hat, which are integrally formed, manufactures.
Further, the interior hat and the material of metal edges are cochrome.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, including interior hat, the interior hat bottom are provided with metal edges, and the metal edges are along interior hat bottomOuter rim track is uniformly arranged, and the height of the metal edges is 0.9-1.1mm, and the width of the metal edges is 0.45-0.55mm.It is logicalThe setting is crossed, metal edges can effectively reinforce the intensity of interior hat, while metal edges are easier to effective undertaking of enamel coating, it is therefore prevented thatThe phenomenon that enamel coating bursts apart, the height of metal edges is 0.9-1.1mm, width 0.45-0.55mm, so that for different tooth bodiesFor the abutment of size, interior hat intensity and porcelain thickness can be effectively ensured, and solved and are preced with intensity in existing baking-ceramic toothIt is poor, be easy to happen the problem of enamel coating bursts apart.
2, in the utility model, the metal edges and interior hat are integrally formed and manufacture.By the setting, further improve interiorThe intensity of hat.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementationExample, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain thisUtility model is not used to limit the utility model.
A kind of interior hat of baking-ceramic tooth, including interior hat 1,1 bottom of the interior hat is provided with metal edges 2, and the metal edges 2 are along interior hat1 bottom outer-edge track is uniformly arranged, and the height of the metal edges 2 is 0.9-1.1mm, and the width of the metal edges 2 is 0.45-0.55mm。
Further, the metal edges 2 are integrally formed with interior hat 1 and manufacture.
Further, the interior hat 1 and the material of metal edges 2 are cochrome.
Embodiment 1
A kind of interior hat of baking-ceramic tooth, including interior hat 1,1 bottom of the interior hat is provided with metal edges 2, and the metal edges 2 are along interior hat1 bottom outer-edge track is uniformly arranged, and the height of the metal edges 2 is 0.9-1.1mm, and the width of the metal edges 2 is 0.45-0.55mm.By the setting, metal edges 2 can effectively reinforce the intensity of interior hat 1, while metal edges 2 are easier to having for enamel coatingEffect is accepted, it is therefore prevented that the phenomenon that enamel coating bursts apart, the height of metal edges 2 is 0.9-1.1mm, width 0.45-0.55mm, is madeIt obtains for the abutment 3 of different tooth body sizes, 1 intensity of interior hat and porcelain thickness can be effectively ensured, and be solved existingHave in baking-ceramic tooth that 1 intensity of hat is poor, is easy to happen the problem of enamel coating bursts apart.
Embodiment 2
On the basis of embodiment 1, the metal edges 2 are integrally formed with interior hat 1 and manufacture.By the setting, further mentionThe intensity of interior hat 1 is risen.
Embodiment 3
On the basis of the above embodiments, the interior hat 1 and the material of metal edges 2 are cochrome.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at thisMade any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility modelProtection scope within.
