Resin dental material IBT Flex

for orthodontic bracketsfor orthodontic bondsfor dental restorations

Product overview
IBT Flex Resin is a Class I biocompatible SLA resin formulated for flexible, tear‑resistant indirect bonding trays and direct composite restoration guides. The formulation balances elongation, tear strength, translucency and color to enable accurate transfer of orthodontic brackets and restorative composites while reducing intraoral adjustments.

Key benefits

• Enhanced elongation and flexibility for atraumatic intraoral placement and removal
• High tear strength for predictable, repeatable fit
• Optimized translucency to visualize brackets, composite and dentition beneath the tray/guide
• High print accuracy and viscoelastic properties that reduce intraoral adjustments
• Manufactured in an ISO 13485‑certified facility; FDA‑registered and CE marked under EU MDR

Applications

• Indirect bonding trays for orthodontic bracket placement
• Direct composite restoration guides

Post-processing (summary)

• Washing: remove uncured surface resin with isopropyl alcohol as the first SLA post‑processing step
• Curing: post‑cure is required for biocompatible materials—follow the material Manufacturing Guide/IFU for exact settings
• For restorative guides: apply a separating agent to the tray to prevent composite adherence
