AIM:The aim of the study was to evaluate and compare the effect of four cordless displacement systems on the amount of gingival displacement lateral and apical directions namely Merocel strips, Traxodent, 3M ESPE retraction pastes and Easy Stat.

Methodology: Clinical efficacy of gingival retraction systems was studied as an expression of adequate lateral and apical gingival displacement by indirect assessment of the sulcus dilation with 3D intraoral digital scanning. The preliminary scans of maxillary right and left 1st premolar was made using 3Shape Trios intraoral scanner.

Results: Least amount of displacement seen with Easy Stat. Merocel strips showed promising results.

Conclusion: Merocel strips showed promising results and should be considered as an effective material of gingival retraction.

Clinical Significance: The cordless systems provided enough gingival displacement for the bulk of impression material to flow within the sulcus, thus recording the prepared and unprepared tooth structure and also retrieval of impression without tearing.
