Dental clinicians prefer the retraction cord technique with hemostatic agents for accurate impressions. While cordless gingival displacement (GD) is faster, conventional methods offer more predictable outcomes.

Area of Science:

Restorative Dentistry
Dental Materials Science

Background:

Accurate impressions are critical for indirect fixed restorations.
Effective gingival tissue management is essential for precise dental impressions.

Purpose of the Study:

To evaluate gingival displacement (GD) techniques used by dental clinicians.
To assess clinicians' knowledge and preferences regarding GD methods.

Main Methods:

A custom electronic survey was distributed to dentists.
Descriptive statistics and Chi-square tests were employed for data analysis.
Participants answered based on their knowledge if not using GD methods.

Main Results:

188 dentists participated; 76.6% use GD techniques.

Keywords:

Gingival displacement Gingival retraction Retraction cord Retraction paste

64.6% reported the retraction cord with hemostatic agent yields higher accuracy.

Only 9.7% found retraction paste technique more accurate.

Conclusions:

Conventional retraction cords with hemostatic agents are favored for predictable impression outcomes.
Cordless GD techniques are perceived as easier and faster but less predictable.
