ACTIVA BioACTIVE CEMENT 5ml Pulpdent

ACTIVA BioACTIVE-CEMENT by Pulpdent is a dual-cure bioactive final cement for indirect restorations, in a 5 ml automix syringe. It releases and recharges with calcium, phosphate, and fluoride ions and responds to the pH cycles of the oral environment.

Format and shades

• Packaging: 5 ml automix syringe.
• Selectable shades: A2 opaque and translucent.
• Dual cure: light-curing and self-curing.

Indications for indirect restorations

The indications listed in the data sheet include:

• Zirconia restorations and CAD/CAM restorations.
• Glass-ceramic and ceramic restorations.
• Resin restorations.
• Metal and metal-ceramic (PFM) restorations.
• Applications in implantology.
• Preformed stainless steel and zirconia pediatric crowns.

Bioactivity and marginal integrity

Apatite formation and ion exchange

The material stimulates the formation of mineral apatite and the natural remineralization process at the material-tooth interface. The release and recharge of significant amounts of calcium, phosphate, and fluoride contribute to the formation of a mineral apatite bonding layer, described as an essential requirement of bioactivity.

Seal at the material-tooth interface

The product description states that ACTIVA BioACTIVE-CEMENT bonds the restoration to the tooth, penetrates and fills microspaces, and seals the margins against microleakage. It also reports reduced sensitivity and protection from secondary caries, with an active role in maintaining oral health.

Composition and strength

Three key components

• Patented bioactive ionic resin.
• Patented elastic resin.
• Reactive glass filler.

The combination of chemical and physical properties offers bioactivity, strength, resilience, durability, and marginal integrity. The elastic matrix absorbs shocks and is resistant to fracture. The original data sheet reports higher chip and fracture resistance compared to other dental cements.

Insolubility and stability

The cement is insoluble, does not crumble, and does not chip. Resistance to discoloration is also listed among the reported characteristics.

Handling characteristics

• Moisture tolerance and simplified technique.
• Automix syringe for quick and easy application.
• Easy removal of excess after hardening.
• No sensitivity reported in the product presentation.

Tissue compatibility and composition

ACTIVA BioACTIVE-CEMENT is described in the product presentation as tissue-compatible and safe for patients. It contains no bisphenol A, Bis-GMA, or BPA derivatives.
