Previously, dental prostheses could be recognized unmistakably at first sight, since they were made of materials that differed greatly in appearance from the real enamel. In place of them came non-metal ceramics - the most progressive and modern version of prosthetics, which provides maximum strength and stunning aesthetics.
What is the use of metal-free ceramics in dentistry?
In addition to prostheses and crowns, the described material is used in the manufacture of veneers, lumineers and inlays (filler inserts). With its help, the restoration of teeth is made, after which they look very natural.
As a rule, non-metal ceramic is installed on the front teeth, as it allows to achieve the best and aesthetic appearance. In addition, the material in question is not suitable for molars due to the fact that during chewing, they experience a high load, capable of damaging ceramic dentures, crowns or patches.
Types of non-metal ceramics
Today at the disposal of dentists there are 3 varieties of this material:
- Pressed ceramics (whole, glass-ceramics). This type of raw material is characterized by a translucent structure that is virtually indistinguishable from natural tooth enamel.
- Based on aluminum oxide. The presented material, besides high aesthetic indicators, is very durable. Therefore, it is possible to make not only single crowns, but also bridges, from ceramics on the frame of alumina.
- Based on zirconium oxide. According to the characteristics of this type of ceramics surpasses the analogue based on aluminum oxide. Zirconium prostheses are hypoallergenic, do not affect the internal organs, gums, own teeth. In addition, such ceramics are more durable and, consequently, durable.
Advantages of non-metal ceramics
In comparison with its direct "competitors", photopolymer and metal-ceramic structures, the described material has the following advantages:
- natural shine of the surface of the restored teeth;
- absolute similarity of prostheses and linings with real enamel;
- more perfect, repeating outlines of own teeth, shape;
- preservation of health and appearance of the adjacent gum;
- absence of inflammatory processes in surrounding soft tissues;
- hypoallergenicity, exclusion of risk of irritation and bleeding;
- sparing preparation, you do not need to grind a large area of teeth;
- natural translucency and beautiful appearance;
- Stable color, not changing for 10-15 years;
- the maximum density of adherence of the material to the gum without damaging it;
- simple and time-consuming independent care;
- a rare need for professional service.
How are crowns made of non-metal ceramics made?
The manufacture of any options for prosthesis begins with the removal of the impression from the jaw. On it further modeling of future crowns , bridges or overlays in accordance with the wishes
On the basis of a wax model, the selected type of ceramics is pressed. If necessary, the received prostheses are additionally corrected and processed with high-precision diamond tools, so that the crowns are perfectly smooth and as close as possible to the gum.
In the future, the restoration of teeth is carried out by a specialist. Correctly made prostheses are installed easily, quickly and painlessly, with a minimum of unpleasant sensations for the patient.
