Dental restoration adhesive Expasyl

for implant systemsgingivalfor impression trays

Overview
Expasyl™ retraction paste is a dental sulcular retraction material designed to provide controlled, minimally invasive gingival displacement for impression-taking and restorative procedures.

Clinical performance
Introduced in 2000 and supported by over 20 years of clinical evidence, Expasyl™ delivers predictable sulcular opening while preserving epithelial attachment, offering an alternative to traditional cord techniques.

Workflow benefits
Expasyl™ is placed into the sulcus in approximately 20 seconds. It acts in 1–2 minutes and is removed easily with a gentle air/water spray. No additional anesthesia or hemostasis is routinely required, simplifying restorative and implant workflows.

Key features

• Reduced pressure vs cord: Generates approximately 143 kPa versus 5,396 kPa for a cord — about 37 times less pressure.
• Controlled viscosity: Formulated to open the sulcus without damaging the epithelial attachment.
• High-precision impressions: Allows impressions to be taken at the same clinical time while gingival tissues remain intact.
• Versatile clinical use: Suitable for prosthetic, restorative and implant-related soft-tissue management.

Indicated for

• Prosthodontics and restorative dentistry
• Implantology and implant prosthetics
