Orthopedic dentistry for the lastdecade has reached a high level of development. Dentists, like jewelers, skillfully hone, implant, model and recreate biocompatible prostheses, fit in size, color and shape to the natural dentition. The absence of a missing incisor or canine is no longer a problem in modern dentistry.
Thanks to innovative technologies and uniquematerials, you can again find a beautiful smile in 33 teeth and do not spread the jaw on the shelf. It is aesthetically pleasing, convenient and maximum safe. The amount of biocompatible materials used for implantation and prosthetics has increased significantly. Therefore, it is difficult for a newcomer to orient himself and understand this complicated matter.
In addition to expensive veneers, lumineers, oxidezirconium and ceramics are particularly sought after by a budget patient using plastic. The latter material is the most economical and affordable for many layers of the population. Metal plastic crown is an orthopedic construction, which is made of several materials: nickel, cobalt and chromium.
Available materials do not cause irritation inoral cavity and inexpensive in price. On top, the crown or prosthesis is covered with a plastic coating. Such a design can be installed both on a temporary and permanent basis. It completely preserves the chewing ability, eliminates the cosmetic defect, protects the native tooth from penetration of pathogenic microorganisms at a significant fit to the gum.
Any dental clinic, or rather a dentistBefore installing the implant or prosthesis must inspect the oral cavity, find out the patient's presence of allergies and only then recommend the material. Metal plastic can be installed in the absence of one or a whole series of teeth (a bridge is made).
In addition, the indications are increasedsensitivity and erasure of enamel. The installation process takes about 10 days, taking into account the fabrication of the structure. Contraindicated prosthesis of this material in the abnormal position of the dentition, atrophy of the alveolar process.
Металлопластмассовая коронка имеет ряд достоинств.The main advantage is an acceptable cost in relation to other materials. Unquestionable advantages include a gentle effect on the gum and tooth enamel. When installed, the orthopedic design does not damage adjacent incisors. It should be noted their reliability due to the presence of a metal base, which is securely attached to the grinded tooth and does not allow it to collapse. The prosthesis made of metal plastic is easily corrected in case of damage or deformation.
There are some disadvantages to this material, but theyare insignificant. Much depends on the professionalism of the doctor who will install the prosthesis. Metal plastic crown loses ceramics in terms of color, wear resistance and aesthetics. It is not so transparent and durable. Holds no more than 5 years with good care.
Однако на практике встречались случаи, когда The implant / dentures were preserved for more than 7 years, not departing from the gum. Due to the low strength, hardness and high porosity, the plastic can be damaged, broken off, and discolored. In this regard, it is not recommended to install on chewing teeth without a metal support. It is important that the design fits tightly to the gum, otherwise the bacteria will accumulate under the crown, which will lead to an inflammatory process and loss of the incisor.
To reduce the load on the pin, dentistsIt is recommended to install plastic structures with a metal base. This allows you to save the chewing function, as accurately as possible to adjust the prosthesis under the bite of the patient and avoid significant pressure on the implanted implant. At the end of the validity period of such a crown (in a few years, when the artificial teeth are fully established), it is possible to install expensive structures made of zirconium dioxide, ceramics, aluminum oxide.
Dental clinic provides guarantees for installed dentures (approximately 12 months). To extend the life of the plastic coating the patient must follow basic rules of hygiene.
With careful care, the crowns will not darken, will not be damaged and will last 5-6 years.
Manufacturing of metal plastic crownscarried out in two stages. First, the dentist removes (grinds) excess tissue, creates a tooth stump under local anesthesia. After that, selects the most approximate color, then removes the casts with the help of soft mass and transmits the blank to a specialist technician. Making a crown takes no more than 10 days.
It is necessary to try on a ready prosthesis,correct, grind and plant on cement. It should be clarified: the metal frame can be stamped and cast. The last option with the impression of the tooth row more accurately repeats the bite of the patient. Cast design is durable, snug fit and allows you to improve the aesthetic appearance. Reputable clinics use only such blanks.
Plastic lining with metal framemuch cheaper than ceramics due to the available materials. The average cost of one unit does not exceed 4000 rubles. In reputable clinics, the price may be increased. Metal plastic crown is the best alternative to golden dentures, with such a design your smile will not suffer. True, the longevity can not hope.
Большинство пациентов положительно говорят о quality of similar products. Conquers the accessibility of the material, the aesthetics of the orthopedic prosthesis. When installing any unpleasant sensations do not feel. The metal base gives strength and retains chewing ability. When hygiene is observed, the coating does not lose its original appearance and is not deformed.
When choosing a material for prosthetics, you shouldguided by the location of the dentition. Of course, the best dental crowns are made on a metal-free basis, although their price is quite high and not everyone can afford it. The choice is yours.
