SINGLE-CORD TECHNIQUE: Poor access Collapsed tissue - Before/During/After
DOUBLE-CORD TECHNIQUE: Good access Better displacement - Before/During/After

Gingival Retraction Techniques: Single-Cord vs. Double-Cord
Single-Cord Technique
Challenges:
Limited access to the sulcus
Tendency for tissue collapse during cord placement
Benefits:
Simplicity and ease of use
Quick procedure for minor tissue management needs
Before
Ensure adequate anesthesia
Dry the gingiva thoroughly
During
Place the retraction cord gently into the sulcus
After
Verify hemostasis
Proceed with impression-taking or other procedures
Double-Cord Technique
Challenges:
More time-consuming compared to single-cord technique
Requires careful placement to avoid tissue trauma
Benefits:
Improved access and displacement of tissue
Greater control over gingival retraction
Before
Ensure adequate anesthesia
Dry the gingiva thoroughly
During
Place the first retraction cord gently into the sulcus
Follow with a second cord placement if needed
After
Verify hemostasis
Proceed with impression-taking or other procedures
