Eight-Year Clinical Performance of Cantilevered Zirconia Resin-Bonded Fixed Dental Prostheses: A Randomized Controlled Trial Evaluating the Effect of Nanostructured Alumina Coating.

Key Points

• The aim is to assess the long-term performance of cantilevered zirconia resin-bonded fixed dental prostheses with a specific focus on the impact of nanostructured alumina coating.
• Conducted a randomized controlled trial
• Evaluated clinical performance over eight years
• Compared NAC with traditional APA under similar conditions
• NAC significantly mitigated mechanical failures compared to untreated zirconia
• Long-term retention rates for NAC were comparable to that of APA
• Demonstrated effective performance for damage-prone translucent zirconia
