Orthopedic dentistry has achieved high development over the past decades. Dentists, like jewelers, skillfully grind, implant, model and recreate biocompatible dentures that are suitable 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 regain a beautiful smile with 33 teeth and not put your jaw on the shelf. It is aesthetically pleasing, convenient and extremely safe. The number of biocompatible materials used in implantation and prosthetics has increased significantly. Therefore, it is difficult for a newcomer to navigate and understand this difficult matter.
In addition to expensive veneers, lumineers, zirconium oxide and ceramics, plastic is in special demand among budget patients. The latter material is the most economical and affordable for many segments of the population. The 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. The crown or prosthesis is covered with a plastic coating on top. Such a design can be installed both on a temporary and permanent basis. It completely retains chewing ability, eliminates a cosmetic defect, protects the native tooth from the penetration of pathogenic microorganisms with significant adherence to the gums.
Indications for prosthetics
Any dental clinic, or rather a dentist, before installing an implant or prosthesis is required to examine the oral cavity, find out the patientās allergies and only then recommend the material. Metalloplastics can be installed in the absence of one or a number of teeth (a bridge is made ).
In addition, the indications are increased sensitivity and erasing of enamel. The installation process takes about 10 days, taking into account the manufacture of the structure. Dentures from this material are contraindicated in case of an abnormal arrangement of the dentition, atrophy of the alveolar process.
Strengths
The metal-plastic crown has several advantages. The main plus is the acceptable cost in relation to other materials. Indisputable 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 a machined tooth and does not allow it to collapse. The prosthesis made of metal-plastic is easily corrected in case of damage or deformation.
but on the other hand
This material has disadvantages, but they are insignificant. Much depends on the professionalism of the doctor who will install the prosthesis. The metal-plastic crown loses to ceramics in color, wear resistance and aesthetics. It is not so transparent and durable. It lasts no more than 5 years with good care.
However, in practice, there have been cases when the implant / dentures were stored for more than 7 years without leaving the gums. Due to its low strength, hardness and high porosity, plastic can be damaged, break off, and change color. In this regard, it is not recommended to install it on chewing teeth without metal support. It is important that the structure fits snugly to the gums, otherwise bacteria will begin to accumulate under the crown, which will lead to the inflammatory process and loss of the incisor.
The use 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 save the chewing function, as accurately as possible to adjust the prosthesis under the patientās bite and to avoid significant pressure on the implanted implant. At the end of the validity period of such a crown (after a few years, when the artificial teeth have fully taken root), it is possible to install expensive structures made of zirconia, ceramics, and aluminum oxide.
Care Rules
The dental clinic provides guarantees for installed prostheses (approximately 12 months). To extend the life of the plastic coating, the patient must follow basic hygiene rules.
- First of all, refrain from the use of dyeing products that adversely affect the color palette.
- Try to avoid hard and hot food so as not to deform the lining.
- After each meal, rinse the oral cavity with water or special means, use dental floss.
With careful care, the crowns will not darken, will not be damaged and will last 5-6 years.
Installation technology
The manufacture of metal-plastic crowns is carried out in two stages. First, the dentist removes (polishes) the excess tissue, creates a stump of the tooth under local anesthesia. Then it selects the most approximate color, then takes impressions with a soft mass and transfers the workpiece to a specialist technician. Making a crown takes no more than 10 days.
The finished prosthesis must be tried on, adjusted, sanded and planted on cement. It should be clarified: the metal frame can be stamped and cast. The last option with a print of the dentition more accurately repeats the patientās bite. Cast design is durable, snug fit and improves the aesthetic appearance. Well-established clinics use only such blanks.
Metal-plastic crowns: unit price
Plastic cladding with a metal frame is much cheaper than ceramic due to the available materials. The average cost of one unit does not exceed 4000 rubles. In reputable clinics, the price can be increased. A metal-plastic crown is the best alternative to gold prostheses, with this design your smile will not suffer. True, longevity is not to be hoped for.
Metal-plastic crowns: customer reviews
Most patients speak positively about the quality of such products. Conquers the accessibility of the material, the aesthetics of the orthopedic prosthesis. When installing, you do not experience any unpleasant sensations. The metal base gives strength and chewing ability. Subject to hygiene, the coating does not lose its original appearance and is not deformed.
When choosing a material for prosthetics, one should be guided by the location of the dentition. Of course, the best dental crowns are made on a metal-free basis, however, their price is quite high and not everyone can afford it. The choice is yours.
