Objective When it is necessary to make tooth preparations subgingivally,it is important that they do not violate the free marginal gingival and attachment epithelium.Methods A technique utilizing knitted gingival retraction cords during tooth preparation and impression procedure was described and 128 teeth were evaluated.Results and Conclusion We found several advantages.It results in less bleeding,limited gingival damage during tooth preparation and clear soft tissue and abutment tooth border.
