Zirconia is quickly proving to be a leader in restorative materials
An increasingly popular choice of restorative materials among dentists, zirconia is proving to offer a dynamic combination of strength and aesthetics. The introduction of the newest zirconia materials have led to aesthetically pleasing, strong and dependable restorations – an advantage over traditional ceramic restorations.
Growing clinical applications
Since its introduction to the dental industry years ago, zirconia has evolved into a diverse, reliable material suitable for a wide range of clinical applications. Compared to the early years, when fewer products were available to achieve proper bonding, today’s full-zirconia crowns offer physical properties and a level of strength and aesthetics said to surpass that of ceramic crowns. Whereas early zirconia restorations were limited to those with proper retention, since the introduction of primers containing MDP, the chemical bond to zirconia has been completely achievable.
Indeed, as more and more clinicians become aware of proper bonding protocols to zirconia surfaces, a growing number of patients are benefiting from efficient, successful restorations. Dental organizations can offer significant support to dentists in the way of educational materials and tools.
For excellent results
For best results, some clinicians are relying on TheraCem, a self-adhesive, resin-based cement that contains MDP. TheraCem offers an optimal bond to both zirconia and the tooth structure, without the need to apply a primer prior to cementation. TheraCem releases calcium and fluoride to the tooth structure, providing transitions from acidic to alkaline ph.
When the preparation has little or no retention, an adhesive procedure is required. The use of an MDP-containing primer such as Z-Prime Plus, which is specifically designed to achieve a chemical bond to zirconia, will provide the best chemical bond to the zirconia surface. A compatible adhesive-cement system is also likely to positively impact the clinical performance of the restoration. All-Bond Universal and Duo-link Universal products are compatible with one another, and the clinical use of this product combination is designed to provide excellent bonding results.
The ability to chemically bond to zirconia will minimize the likelihood of restorations falling off or de-bonding. Not only is less material required, patients will experience minimal chair time. And great results are certain to lead to enhanced patient satisfaction.
