Evidence-based knowledge on the aesthetics and maintenance of peri-implant soft tissues: Osteology Foundation Consensus Report Part 2—Effects of hard tissue augmentation procedures on the maintenance of peri-implant tissues

Abstract

Objectives

One task of Working Group 1 at the 2nd Consensus Meeting of the Osteology Foundation was to comprehensively assess the effects of hard tissue augmentation procedures on peri-implant health or disease.

Materials and methods

One systematic review and meta-analysis on the effects of hard tissue augmentation procedures included a total of eight studies (n = 12 publications). Consensus statements, clinical recommendations, and implications for future research were based on structured group discussions and plenary session approval.

Results

After 1–10 years of follow- up, lateral bone augmentation procedures were associated with peri-implant tissue stability, as evidenced by minimal and non-significant changes in bleeding on probing, probing depth, and marginal bone levels. Case definitions based on clinical and radiographic parameters to differentiate peri-implant health from disease have been inconsistently employed in the studies investigated.

Conclusions

Lateral bone augmentation procedures are associated with peri-implant tissue stability on short-term (1–3 years) and midterm follow-ups to long-term (>3 years) follow-ups.
