The European contribution to osseous resective surgery for the treatment of residual pockets and furcation defects

Periodontology 2000, EarlyView.
Abstract For decades, osseous resective surgery along with apically positioned flap procedure has been advocated as a predictable treatment option to reduce residual pockets and minimize periodontal complications during supportive periodontal care. More recently, Fiber Retention Osseous Resective Surgery (FibReORS) has been suggested to reduce the ...

The efficacy of biologic factors on the surgical therapy of periodontal suprabony defects: A systematic review and network meta‐analysis of randomized clinical trials

Periodontology 2000, EarlyView.
Abstract Objectives This systematic review investigated the efficacy of biologic factors in the surgical treatment of periodontal suprabony defects. Materials and Methods Three databases were searched to identify RCTs comparing open‐flap debridement (OFD) combined with biologic factors only, or combined with bone substitute, and/or barriers to the same

Emerging risk factors influencing the occurrence of peri‐implantitis

Periodontology 2000, EarlyView.
Abstract Background The objective of the present review is to explore the evidence and biological plausibility of factors that may expose dental implants to a greater likelihood of developing peri‐implantitis. Material and Methods An electronic screening on the PubMed library the was carried out to identify potential emerging factors that influence the

Marginal bone loss around implants – What does it mean?

Periodontology 2000, EarlyView.
Abstract Background Changes in peri‐implant marginal bone levels (MBL) constitute a central outcome in studies on implant therapy and reflect the integrity of the supporting tissues over time. Aim To summarize current evidence on MBL changes around dental implants, with emphasis on temporal patterns, methods of assessment and their clinical ...
