Assessing Survival Rates of Zirconia Dental Implants

Assessing Survival Rates of Zirconia Dental Implants

Nanoparticle zirconia dental restorations have gained popularity due to their durability, strength, and esthetics. The review “Clinical Outcomes of Zirconia Dental Implants: A Systematic Review,” published online in September by the Journal of Dental Research, sought to examine the survival rate and marginal bone loss of zirconia dental implants on single crowns or fixed dental prostheses.

The systematic review pulled from randomized controlled clinical trials and prospective clinical trials with more than 15 patients. Results showed that implant loss was most common within the first year of zirconia-implant placement. In analysis of subsequent years, researchers noted the survival rate held at 95.6%, with a decrease of 0.05% per year. No variations in material, design, or restorative type notably impacted marginal bone loss. The review concluded that zirconia implants remain a viable restorative option, noting, however, that their long-term predictability still required greater observation and analysis.
