Good marginal adaptation is the most important characteristic for the long-term success of complete coverage restorations. Marginal adaptation is essential for the prevention ofmicroleakage. Improper fit can affect the fracture strength of silica-based ceramic crowns, reducing the strength and longevity of the restoration. Thus, a technique of seal improvement is described.
