Purpose: To update an existing systematic review assessing the clinical performance of full-arch implant-supported monolithic zirconia fixed dental prostheses.
Materials and methods: The review was conducted according to the guidelines outlined in the Preferred Reporting Items of Systematic Reviews and Meta-analyses (PRISMA) statement. An electronic search was conducted using the PubMed, Science Direct and Cochrane Library databases to identify clinical studies on full-arch implant-supported monolithic and minimally layered zirconia fixed dental prostheses. Human studies with a mean follow-up of at least 1 year and published in an English-language peer-reviewed journal up to April 2020 were included. Two independent examiners conducted the search and the review process.
Results: The search generated 2110 articles. Thirty-three qualifying studies were retrieved for full-text evaluation and a total of 17 studies were included on the basis of preestablished criteria. All 17 studies reported satisfactory clinical and aesthetic outcomes. The technical complication rate related to this type of prosthesis is still minimal and survival rates are high.
Conclusions: Full-arch dental implant restoration with monolithic zirconia is associated with high short-term success. Long-term data from studies with a strong level of evidence are still lacking.
