Tenure Multi-Purpose Bonding System has demonstrated a proven clinical record of successful restorations with high bond strengths and excellent retention, combined with significant reduction of microleakage and post-operative sensitivity. Tenure is the first bonding agent accepted by the American Dental Association and a 4th generation multi-purpose, chemical curing, adhesive system for bonding any resin restorative to all intraoral surfaces. Tenure A and B multi-purpose, self-cure adhesive bonds to the five intraoral surfaces - enamel, dentin, porcelain, composite and metal. Tenure S is a single component, light cured, hydrophilic bonding agent that further enhances bonding. When used in combination with Tenure A and B, Tenure S offers even greater bond strengths to intraoral surfaces.
