Die Proximal Box Elevation zur Therapie tiefer Defekte Anne-Katrin Lührs Recommend Article Abstract Buy Article All articles of this category Tiefe subgingivale Defekte sind primär nicht durch indirekte Adhäsivrestaurationen versorgbar. Die Proximal Box Elevation (PBE), die durch Einbringen einer Kompositstufe die Präparationsgrenze von sub- nach supragingival verlegt, ermöglicht das spätere adhäsive Zementieren unter absoluter Trockenlegung. Dieser Beitrag präsentiert einen Überblick über die aktuelle wissenschaftliche Literatur und illustriert das klinische Vorgehen mit Fallbeispielen.
