Deep Margin Elevation

Why aren’t all dentists performing deep margin elevations with composite? It might be because you’re listening to old research. “Violating the biologic width” was disproven in 2014. Gingival tissue doesn't have an adverse reaction to the material, it has an adverse reaction to the biofilm under a retention crown or poorly bonded restoration. If you have experienced failures with glass ionomers, use composite instead. In 2019, 12-year clinical evaluations showed the success of composite, a material that better mimics a natural tooth compared to brittle glass ionomers. Understanding how to perform deep margin elevations is an essential tool for dentists wanting to save more teeth.
