Zirconia implants show a 10-year cumulative survival rate of 95.1%: a systematic review
Zirconia implants show a 10-year cumulative survival rate of 95.1% along with minimal short-term marginal bone loss. This is the result of the systematic literature review and meta-analysis performed by Mohseni et al. (2023). The review has particular clinical relevance, as it is currently the only paper that has analyzed studies with a 10-year follow-up in which two-piece zirconia implants were involved.
A total of 25 studies were included, comprising 4,017 implants (including 49 Zeramex T implants) and 2,083 patients. Seven of these studies reported follow-up periods exceeding 60 months. The inclusion criteria encompassed clinical studies—randomized or non-randomized—that provided data on implant failure rates among patients receiving zirconia dental implants. Conversely, studies focusing on zirconia implants designed to replicate the root anatomy via laser scanning of the extracted tooth were excluded, as were case reports, technical reports, animal studies, in vitro studies, and review papers.
As Mohseni et al. (2023) conclude,
- Zirconia implants exhibit a 10-year cumulative survival rate of 95.1%, along with minimal short-term marginal bone loss
- Over long-term follow-up (up to 132 months), the average marginal bone loss ranged from 0.632 to 2.060 mm
- On average, marginal bone loss increased by approximately 0.005 mm for each additional month of follow-up
- No significant difference in survival rates was observed between implants placed in the maxilla versus the mandible (p = 0.637)
