A kind of labial teeth baking-ceramic tooth coronaTechnical field
The utility model belongs to baking-ceramic tooth technical field, and in particular to a kind of labial teeth baking-ceramic tooth corona.
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 labial teeth baking-ceramic tooth is in the production process due to the factors such as production technology, interior Guan Shecechu and porcelainLayer junction is plane, so that enamel coating is not easy accumulation and the problem of tomography collapses porcelain easily occurs when upper porcelain.
Utility model content
The purpose of this utility model is that: a kind of labial teeth baking-ceramic tooth corona is provided, when solving porcelain on existing labial teeth baking-ceramic toothEnamel coating is not easy accumulation and the problem of tomography collapses porcelain easily occurs.
The technical solution adopted in the utility model is as follows:
A kind of labial teeth baking-ceramic tooth corona, including it is outer hat, interior hat, it is described it is outer hat be sheathed in label, the tongue side of the interior hatIt is provided with zirconium dioxide convexity layer, lock chamber is provided in the interior hat, fixed reinforcer is provided in the lock chamber, it is describedFixed reinforcer includes the fixed clamping bar that two sidewall slopes along lock chamber are arranged, the side wall of the fixed clamping bar and lock chamberBetween connect resilient material.
Further, the both ends of the fixed clamping bar are provided with arc connection strap, the end connection of the arc connection strapThere is buckle, the side wall of the lock chamber is connected with retaining ring, and the buckle is adapted with retaining ring.
Further, the width of the zirconium dioxide convexity layer is 0.5-0.6mm.
Further, the material of the interior hat is zirconium dioxide, and the interior hat is integrally formed with zirconium dioxide convexity layer.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, including outer hat, interior hat, the outer hat be sheathed in label, the setting of the tongue side of the interior hatThere is zirconium dioxide convexity layer, lock chamber is provided in the interior hat, fixed reinforcer, the fixation are provided in the lock chamberReinforcer includes the fixed clamping bar that two sidewall slopes along lock chamber are arranged, between the fixed clamping bar and the side wall of lock chamberConnect resilient material.By the setting, the tongue side setting zirconium dioxide convexity layer being preced with inside can not only increase occlusion space,Zirconium dioxide convexity layer and enamel coating are easier to accept accumulation simultaneously, greatly reduce the work difficulty of porcelain personnel, also preventTomography collapses the generation of porcelain phenomenon.In porcelain on to baking-ceramic tooth, fixed clamping bar and elastic material cooperation keep interior hat adaptiveIt is fixed, corona keeps stablizing when going up porcelain in this way, is easy to upper porcelain personnel operation, porcelain when solving porcelain on existing labial teeth baking-ceramic toothLayer is not easy accumulation and the problem of tomography collapses porcelain easily occurs.
2, in the utility model, the both ends of the fixed clamping bar are provided with arc connection strap, the end of the arc connection strapPortion is connected with buckle, and the side wall of the lock chamber is connected with retaining ring, and the buckle is adapted with retaining ring.By the setting, it is convenient forFixed clamping bar and lock chamber is sufficiently fixed, while constraint limit can be carried out to elastic material.
3, in the utility model, the material of the interior hat is zirconium dioxide, the interior hat and zirconium dioxide convexity layer oneMolding.By the setting, so that interior hat is structure as a whole with zirconium dioxide convexity layer, be not only convenient for enamel coating and accumulated, also improvedThe tolerance intensity of interior hat and zirconium dioxide convexity layer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Marked in the figure: being preced with outside 1-, hat, 3- fixed clamping bar, 4- elastic material, 5- zirconium dioxide convexity layer, 6- arc in 2-Connection strap, 7- buckle, 8- retaining ring.
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 labial teeth baking-ceramic tooth corona, including outer hat 1, interior hat 2, the outer hat 1 are sheathed on interior hat 2, the interior hat 1Tongue side is provided with zirconium dioxide convexity layer 5, is provided with lock chamber in the interior hat 2, fixed reinforcement is provided in the lock chamberPart, the fixed reinforcer include the fixed clamping bar 3 that two sidewall slopes along lock chamber are arranged, the fixed clamping bar 3 with it is solidDetermine to connect resilient material 4 between the side wall of chamber.
Further, the both ends of the fixed clamping bar 3 are provided with arc connection strap 6, and the end of the arc connection strap 6 connectsIt is connected to buckle 7, the side wall of the lock chamber is connected with retaining ring 8, and the buckle 7 is adapted with retaining ring 8.
Further, the width of the zirconium dioxide convexity layer 5 is 0.5-0.6mm.
