Metal-plastic crown: installation, service life, reviews

Orthopedic dentistry over the past decade 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 unique materials, 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 as safe as possible. 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, zirconium oxide and ceramics, plastics is particularly sought after by a budget patient. 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 in the oral cavity and are 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 the penetration of pathogenic microorganisms with a significant fit to the gum.

Indications for prosthetics

Any dental clinic, or rather a dentist, before installing the implant or prosthesis must inspect the oral cavity, find out the patient's allergy 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 hypersensitivity and erasure of enamel. The installation process takes about 10 days, taking into account the construction of the structure. Contraindicated prosthesis of this material in the abnormal position of the dentition, atrophy of the alveolar process.

Strengths

Metal-plastic crown has a number of advantages. The main advantage is an acceptable cost in relation to other materials. Undeniable benefits include a gentle effect on the gum and tooth enamel. At installation 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. A prosthesis made of metal plastic can be easily adjusted for damage or deformation.

but on the other hand

The minuses of this material are, but they are 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 strong. Holds no more than 5 years with good care.

However, in practice, there were cases when the implant / dentures lasted more than 7 years, without 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 fit tightly to the gum, otherwise the bacteria will accumulate beneath the crown, which will lead to an inflammatory process and loss of the incisor.

Application of metal plastics on implants

To reduce the load on the pin, dentists recommend installing plastic structures with a metal base. This allows you to keep the chewing function, as accurately as possible to correct the prosthesis under the bite of the patient and to avoid significant pressure on the implanted implant. At the end of the life of such a crown (in a few years, when artificial teeth will fully live), it is possible to install expensive structures of zirconium dioxide, ceramics, aluminum oxide.

Care instructions

The dental clinic gives guarantees for the prosthesis to be installed (approximately 12 months). To prolong the life of the plastic coating, the patient must comply with basic hygiene rules.

• First of all, to refrain from using coloring products that adversely affect the color palette.
• Try to avoid hard and hot food, so as not to deform the facing.
• After each meal, rinse the oral cavity with water or special means, use a thread for the teeth.

With careful care, crowns will not darken, they will not get injured and will last 5-6 years.

Installation technology

The production of metal-plastic crowns is carried out in two stages. First, the dentist removes (polishes) excess tissue, creates a stump of the tooth under local anesthesia. Then he selects the most approximate color, then removes the impression with a soft mass and passes the workpiece to a specialist technician. Crown production takes no more than 10 days.

Ready prosthesis should be tried on, adjusted, sanded and planted on cement. It should be clarified: the metal frame can be stamped and cast. The latter variant with an impression of the dentition more accurately repeats the patient's bite. The cast construction is characterized by durability, tight fit and allows to improve the aesthetic appearance. Solid clinics use only such blanks.

Metal plastic crowns: unit price

Plastic lining with a metal frame is much cheaper than ceramics because of the available materials. The average cost of one unit does not exceed 4000 rubles. In respectable clinics, the price can be increased. Metal plastic crown is the best alternative to gold prostheses, with such a design your smile will not suffer. True, it is not necessary to hope for longevity.

Metal plastic crowns: customer reviews

Most patients speak positively about the quality of such products. It accelerates the availability of material, the aesthetics of the prosthetic prosthesis. At installation any unpleasant sensations you do not test. The metal base gives strength and keeps chewing ability. If hygiene is observed, the coating does not lose its original appearance and does not deform.

When choosing a material for prosthetics, the location of the dentition should be guided. Of course, the best dental crowns are made on a non-metal basis, however, their price is quite high and not everyone can afford. The choice is yours.
