Dental restoration adhesive Expasyl Exact

for restorationCAD/CAMgingival

Product overview
Expasyl™ Exact is a single‑use retraction paste formulated for atraumatic sulcular opening and soft‑tissue management during restorative and prosthetic procedures. Packaged as one capsule per patient, it is compatible with standard composite applicator guns and designed to simplify clinical workflow.

Clinical background
More than 20 years of clinical use: Expasyl™ paste was introduced in 2000 as an alternative to traditional retraction cords to achieve atraumatic sulcular opening and predictable tissue displacement for impressions and restorations.

Usage
One capsule per patient: single‑use capsule reduces cross‑contamination risk and waste. The capsule fits any composite applicator gun. Typical protocol is rapid application followed by a short contact time to enable immediate digital or conventional impressions.

Key benefits

• Effective & atraumatic — Viscosity and formulation open the sulcus effectively while preserving the epithelial attachment.
• Optimized for CAD/CAM — Improves sulcus visibility and moisture control for more accurate digital scans: you scan what you see.
• Fast, simple protocol — 3‑minute protocol with maximum contact time of 2 minutes; no routine additional anesthesia or hemostasis required.
• Demonstrated performance — Generates 1.7 to 9.2× the pressure of other retraction pastes in comparative testing, sufficient for reproducible sulcus opening.
