Titanium For Implants And Zirconia For Crowns

The introduction of new and more advanced materials in the field of dentistry and the evolution of processing techniques has allowed crown restorations for badly fractured teeth. Patients today have a choice from different materials to fabricate single-unit crowns that are best suited to their needs.

Titanium is considered king when it comes to dental implants. However, experts in the dental industry are keeping close watch over some materials that could be used for implants. One of these materials is zirconia, a strong hard material that is also used to make crowns and bridges. Like titanium, zirconia fuses well to the bone. Zirconia has a white color which is a very important factor for dentistry. It allows transformations to any shade so that the dental crown will match the rest of the teeth.

It is rare for a person to have allergic reaction to zirconia. Unlike other materials, zirconia does not chip off easily and can tolerate chewing and biting forces. It adheres well to the tooth to ensure that the crown is permanently in place.

One of the issues when using metals is the smile zone or aesthetic zone where the metal used shows above the gum or the gum looks dark or black. The use of zirconia makes an implant more aesthetically pleasant. This is the reason why zirconia is an important material in crowns and implants. However, zirconia won’t be replacing titanium any time soon particularly since more than 95% of dental implants are made from titanium.

When metals are placed in the body, they must resist the aggressive environment that potentially contains corrosive elements. Titanium spontaneously forms a protective oxide layer on its surface making it more corrosion-resistant than other metals. In dental implants, titanium becomes tightly integrated into the jawbone to minimize the risks of loosening and failure.

One of the reasons crown restorations are very popular is the superior looks that exactly resemble the natural tooth. As long as the crown is maintained properly, it can stay inside the mouth forever. While implants are the most popular choice, dental crowns are more cost efficient and takes only a few appointments to complete.
