Evidence‐based recommendation (3.7)
We recommend treating teeth with residual deep pockets associated with intrabony defects 3 mm or deeper with periodontal regenerative surgery.
Supporting literature Nibali et al. (2019)
Quality of evidence Twenty‐two RCTs (1,182 teeth in 1,000 patients)—four studies at low risk of bias—there is consistency of direction of benefit but high heterogeneity for superiority of regeneration over open flap debridement.
Grade of recommendation Grade A—↑↑
Strength of consensus Consensus (10% of the group abstained due to potential CoI)
