Full-ceramic Restorations

We Fabricate Long-lasting Zirconia Dental Crowns

Zirconia structures from Oceanic Dental Laboratory are designed with 3D scans of the patient, impression, or model. To ensure the best outcome for your restorations, follow our Zirconia Preparation Guidelines. The core is then milled from a single block in a soft pre-sintered state. Once milled, the Zirconia is sintered where it reaches its full strength of 1200MPa. These are typically five times stronger than porcelain fused to metal crowns.

Aesthetic Zirconia Restorations

Aesthetically, a Zirconia crown is pleasing to the eye as not only does it look like a real tooth, it also has the ability to reflect light in the same manner as a natural tooth. Because of this, Zirconia is a good choice for patients who might require a crown positioned at the front of their mouth as they offer a more realistic, streamlined, and less bulky option than some porcelain veneers.

Benefits

One of the major health benefits is that it is biologically safe to use in your mouth for many years and will not be rejected. The patient will also avoid having a black gum line which can be visible when using a porcelain fused metal crown.

Using a tooth crown allows the dentist to retain more of the original tooth, which means there is less preparation time needed to perform the procedure. This is not only beneficial to the dentist in man hours but also to the patient in a case where the crown has to be removed at a later date.

Downsides of Zirconia

Although the popularity of Zirconia dental crowns in Australia continues to rise, some dentists still prefer other options like PFM crowns or gold. This is due to it’s durable nature. A bridge or crown may cause friction against the root of the tooth it is fixed upon or the neighbouring teeth. Decay in teeth under a crown are often less noticeable until the crown falls off.
