New Basic Law of Dental Ceramics

The rule used to be that all-ceramic bridges were at best suitable for the anterior tooth region. Even the glass-infiltrated aluminium oxide frameworks suitable in terms of their bending strength did not withstand the masticatory loads in the posterior tooth region. The junctions of pontics in particular were at considerable risk of fracture. But the rules have changed in your favour. With zirconium oxide, there is now an alternative that is three times better than glass-infiltrated ceramics in terms of its fatigue properties and which has already proven its wonderful suitability in clinical studies.

The Clinical Foundations

A long-span zirconium oxide all-ceramic bridge has no problem withstanding the masticatory forces of 800-900 Newtons. If you are amazed and think this is hardly possible, that’s an understandable reaction! At the end of the day, no other high-strength structural ceramic currently known has these kinds of material properties. It goes without saying that zirconium oxide is a truly exceptional material. Many years of clinical studies at ETH Zurich verify its wonderful suitability for all-ceramic bridges of up to four units.
