An Archetype Relocates in the Management of Emergence Profile- 'The EBC Principle' in Implantology: A Narrative Review.

ABSTRACT Successful integration of implant-supported restorations depends on achieving a precise balance between mucosal aesthetics and long-term peri-implant tissue stability. The Esthetic Biological Contour (EBC) concept introduces a structured, multi-zonal approach for designing the subgingival emergence profile. By dividing the transmucosal component into defined zones, each corresponding to specific anatomical tissue barriers, the EBC framework allows for tailored restorative morphology, informed biomaterial selection, and targeted surface treatments. This review examines the EBC concept, compares it with conventional geometric principles, outlines its multi-zonal clinical protocols, and evaluates current scientific evidence supporting its effectiveness in preserving marginal bone levels and enhancing soft tissue architecture.
