Biological Width Considerations in Vertical Crown Preparation: Clinical and Esthetic Outcomes

The biological width is regarded to be crucial for preserving gingival health. Vertical edgeless preparation improves flexibility of the prosthetic margin as well as emergence profile. Furthermore, it provides a conservative alternative in which the finish line has been represented by an area instead of a horizontal line. This review analyzes the biological width related with vertical crown preparation with an emphasis on clinical together with esthetic outcomes.
