Frequently Asked Questions
We decided to answer some frequently asked questions related to the procedure: placement of veneers asked by our patients.
We mentioned the strength of zirconium crowns, which is as close as possible to that of natural teeth - reaches up to 1200 megapascals. It is no coincidence that before it entered medical use, zirconium was widely used in the military industry and aircraft construction. Compared to ceramic, which is known for being quite brittle – reaching a strength of only 350 megapascals, zirconia is much stronger.
- Anti-allergic material – the first use of zirconia is related to the manufacturing of artificial joints. After conducted numerous tests, the material does not cause any side or allergic reactions in patients. Similarly, its use for crowns making is entirely safe and preferred by many patients with allergies to different materials or metals.
- Durability - thanks to their smooth surface, zirconia crowns are resistant to the development of bacterial plaque, which is often the cause of gum pain and the formation of such unpleasant gum pockets. In addition, zirconia is more resistant to staining and the appearance of spots than other types of crowns.
- They are teeth- friendly - both for the teeth themselves, on which the crowns are placed, as well for the others, the zirconium is more gentle. The reason for this is the need for less filing of the teeth being worked compared to the other alternatives. They are also more gentle on the rest of the teeth in the mouth they touch because they are smoother and the likelihood of breaking or scratching is minimized. Innovation in manufacture – unlike the crowns known so far, zirconia crowns are manufactured with special CAD/CAM technologies that minimize the risk of errors.
Metal-ceramics are accepted as a robust veteran in dentistry, but let's not forget that this is at the expense of its biocompatibility. Many patients exhibit allergies to the metal, necessitating further restoration
- Another patients’ legitimate concern is related to the gray tint of the metal frame used. The light transmission is severely limited, making the teeth look artificial;
- Ceramic over metal very often breaks off because the solder between metal and ceramic is chemical;
In case of metal corrosion, metal-ceramics cause unpleasant darkening and blackening of the gum;
- Metal conducts an amount of heat, and therefore sensitivity to hot and cold may be encountered;
- Tooth filing by 1.5-2.0 mm.
An interesting fact is that as a material, zirconia is twice as resistant as metal-reinforced ceramics and about 5 times more resistant than pure ceramics. On the other hand, zirconium is accepted as a symbol of natural aesthetics
