简要总结
Regardless of the selected technique for dental impression, gingival displacement is an essential procedure specially when making impressions of subgingival finishing lines, because a moisture-free sulcus is a requirement for an effective impression.
The objective of this randomized clinical study is to evaluate the efficacy of the conventional and cordless gingival displacement (GD) techniques.
详细描述
On conventional technique we normally use a cord for gingival displacement. On the other hand, on cordless technique do not require this need.
