Effect of sub‐marginal instrumentation before surgical treatment of peri‐implantitis: A multi‐centre randomized clinical trial

Abstract

The present multi-centre randomized clinical trial did not demonstrate an added effect of performing sub-marginal instrumentation 6 weeks before the surgical treatment of peri-implantitis. Larger clinical trials are however needed to confirm the present findings (Clinicaltrials.gov: NCT03620331).
