Abstract

This study addresses the durability and complications of zirconia dental implants through a prospective clinical investigation. Zirconia implants are increasingly utilized in dental implantation, and a comprehensive understanding of their long-term performance is essential.

Background: Zirconia dental implants have gained attention due to their biocompatibility and aesthetics. However, research on their extended success and complication rates is limited.

Materials and methods: A prospective clinical study involved the placement of 30 zirconia dental implants in patients requiring tooth replacement. The implants were followed up for five years. Success was defined as the implant remaining stable and functional. Complications, including peri-implant mucositis and peri-implantitis, were monitored. Statistical analysis included descriptive statistics, Chi-square test, and P-values were set at P < 0.05.

Results: The long-term success rate of zirconia dental implants was found to be 93.3%. Among the 30 implants, only 2 exhibited failure. The most common complication was peri-implant mucositis, occurring in 16.7% of implants. Notably, the incidence of peri-implantitis was limited, observed in 6.7% of implants. Statistical analysis showed significant associations between implant failure and smoking (P = 0.021).

Conclusion: Zirconia dental implants demonstrated a high long-term success rate of 93.3% over five years. Peri-implant mucositis was the predominant complication, with a relatively low occurrence of peri-implantitis. The findings underscore the potential of zirconia implants for reliable dental implantation. Addressing modifiable risk factors, such as smoking, could further enhance implant success. Continued research is recommended to validate and expand upon these outcomes.
