Deep Margin Elevation

Smart Margin Lift (SML) is a minimally invasive technique used in restorative dentistry to elevate deep subgingival margins making them more accessible for restoration without the need for aggressive crown lengthening or extensive tooth reduction. This method involves carefully isolating the affected tooth preparing the deep margin and applying a resin-modified glass ionomer (RMGI) or bulk-fill composite to elevate the margin coronally. Once the material sets the final restoration-whether a composite onlay or crown can be placed without encroaching on the biologic width.SML offers several advantages including preservation of healthy tooth structure improved marginal seal enhanced restoration longevity and better gingival health due to its biocompatibility. It is particularly useful in cases where subgingival caries deep cervical fractures or preparations extend beyond the gingival margin making traditional restorative approaches challenging. By providing a predictable and efficient solution Smart Margin Lift is becoming a preferred technique in minimally invasive and adhesive dentistry.
