The loss of chewing teeth is accompanied not only by daily discomfort, but also by negative consequences for human health in general. Modern dentistry solves this problem. The implantation of chewing teeth allows you to restore the removed dental units with full functionality. Let us consider in more detail the features of the procedure, methods, materials and other important details of the restoration of the upper and lower jaws.
Contraindications
Despite the budgetary cost and reliability, a metal-plastic crown is not indicated in all cases. The first and most important contraindication is the presence of an allergic reaction to materials. In this case, orthopedic dentists will choose another safe type of restoration technique for your clinical case.
Other contraindications to the installation of a metal-plastic crown:
anterior teeth at an abnormal height
chronic, severe form of periodontitis
pathological bite of the second or third degree
there are reversals, crowding and other serious bite defects
the presence of inflammatory processes in the development of gingivitis or periodontal disease
Advantages and disadvantages
For metal-plastic crowns for teeth, the price is noticeably lower than the cost of prosthetics using metal ceramics. However, this is not the only advantage of these fixed structures.
Finished metal-plastic crowns for teeth are safe for enamel and mucous membranes. They can be used as temporary solutions for implantation. The structures are distinguished by reliable fixation, maintainability without dismantling, and the ability to withstand chewing loads. Fast production allows you to install them even in 1 day.
However, the metal-plastic prosthesis also has significant disadvantages:
low service life – usually the crown is able to serve its owner for no more than 5 years
the porous structure of the plastic, due to which the patient has to refuse products with natural or artificial colors
plastic is not able to convey the natural shade of the tooth and the transparency of the enamel, so there may be a noticeable difference
Also, the orthopedic dentist has to sharpen the tooth heavily in preparation for the installation of a non-removable metal-plastic structure. At the consultation, the specialist will inform you about all the disadvantages and advantages of the technique, so that the decision on prosthetics is balanced.
Types of metal-plastic crowns
According to the manufacturing method, metal-plastic crowns are stamped and cast. Stamping involves the use of standard blanks.
For cast metal-plastic crowns, the price is slightly higher. However, there is no risk of a leaky fit of the structure, the development of diseases, the difference in the color of the product from the shade of “native” teeth.
Life time
Usually metal-plastic crowns are used for 3-5 years. The need to replace structures arises with the appearance of chips, cracks and other visible defects. It is also worth considering a visit to the orthopedist when the crowns have changed color.
If crowns are used as a temporary solution, then they are removed to install a permanent restoration over the titanium root.
Care
It depends on the patient how long the metal-plastic crown will last and how long it will retain its original appearance. It is very important to carefully monitor oral hygiene – brush your teeth three times a day and do not forget to rinse.
Other care tips:
use a soft bristled toothbrush
Avoid abrasive pastes
do not eat carrots, nuts, seeds and hard foods that can deform the prosthesis
avoid foods and drinks with natural or artificial colors
Get regular professional dental cleanings
