Why do dentists recommend zirconium dioxide all-porcelain teeth?
Having a neat and beautiful tooth is one of the top ten modern health, is a symbol of status, is a noble quality of life, one of the performance, porcelain teeth has long been a fast and effective way to restore teeth, but the metal ions of metal porcelain teeth will produce adverse reactions to the human body, such as gum blackening, gum bleeding atrophy, etc... Due to the presence of the metal inner crown, the light transmission, colour and shape of the natural teeth there is a big difference, but also in the light to produce a blue-grey effect. At the same time, metal porcelain teeth are unstable under the action of bacteria in the liquid oral acidic and alkaline environment, and patients have some interference with metal when doing CT MRI. Therefore, the dental medical profession has been trying to change this state, and currently the international dental profession is popular with a newest porcelain teeth without metal crowns - zirconia all-porcelain series.
Is zirconia safe?
Zirconia for both medical and dental use has an excellent track record in terms of biosafety. Over the years, numerous experiments and clinical cases have demonstrated that zirconia has no toxic effects on bone or soft tissue cells. No allergic reactions have been reported.
Is the chipping rate of zirconia restorations high?
A large number of studies have shown that the incidence of chipping in zirconia is no higher than in conventional porcelain restorations. The main causes of chipped porcelain are threefold:
1, poor design of the base crown form, local surface decorative porcelain too thick;
2, decorative porcelain sintering is not in accordance with the standard temperature control, such as rapid cooling;
3, the doctor did not adjust the jaw after a reasonable treatment, such as re-glaze sintering, or standard three-step polishing, etc. ... These are all mandatory steps.
Does full zirconia cause excessive wear on the opposing jaws?
All-zirconia restorations are a good choice for patients with a tight bite and insufficient space for preparation. If you are concerned about excessive wear on the jaws, there is no need to be, as the wear properties of zirconia depend on the smoothness of the surface, not the hardness. Therefore, a polished or enamelled full zirconia restoration will not cause excessive wear to the jaws.

1. The colour is very similar to that of natural teeth, with a high degree of aesthetic effect, excellent light transmission and more suitable for use in areas with high aesthetic requirements.
2. No metallic odour in the mouth, no corrosion, no stimulation of the pulpal nerve due to alternation of hot and cold, excellent biocompatibility, long lasting and durable. Can withstand high strength biting force, prevent fracture, strong and durable. Solves the problem of metal porcelain gum translucency, black line and discolouration.
