Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

On conventional technique we normally use a cord for gingival displacement. On the other hand, on cordless technique do not require this need.
