Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.
