The subgingival finish line in indirect restorations plays a critical role in achieving both esthetic integration and functional stability. This article reviews the clinical indications and placement techniques of subgingival finish lines, and examines the associated challenges and their potential solutions. Particular emphasis is placed on the influence of convex subgingival contours on periodontal tissues and the biological limitations of finish line placement in relation to supracrestal tissue attachment. Furthermore, the indications for deep subgingival margin placement are delineated, accompanied by specific technical recommendations. This paper aims to provide a framework for treatment planning that harmonizes esthetic excellence with the preservation of periodontal health.
