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 ...

Peri‐implantitis—Is it mainly a clinician‐initiated complication of implant therapy?

Periodontology 2000, EarlyView.
Abstract Aim The high prevalence of peri‐implantitis is concerning, with a growing consensus that the majority of cases are complications initiated by clinician‐related errors rather than classic pathology. A primary predisposing factor for peri‐implantitis is exposure of the micro‐rough implant surfaces to the peri‐implant sulcus after treatment ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which
