ACTIVA RESTORATIVE COMPOSITE

ACTIVA BioACTIVE-RESTORATIVE is a highly esthetic, bioactive composite that delivers all the advantages of glass ionomers in a strong, resilient, resin matrix that will not chip or crumble. 

It chemically bonds to teeth, seals against microleakage, releases more, calcium, phosphate and fluoride and is more bioactive than glass ionomers, and is more durable and fracture resistant than composites

ACTIVA is the first bioactive composite with an ionic resin matrix, a shock-absorbing resin component and bioactive fillers that mimic the physical and chemical properties of natural teeth. It releases and recharges with calcium, phosphate and fluoride ions, delivering long-term benefits and better oral health care for your patients.

ACTIVA contains no Bisphenol A, No Bis-GMA and no BPA derivatives.

Moisture tolerant – Simplified technique

Bioactive restorative materials are relatively new in dentistry. They are restoratives that are moisture friendly, transport water, and stimulate apatite formation at the material-tooth interface. In addition, these resins react to pH changes in the mouth by releasing and up-taking calcium, phosphate and fluoride ions, thus helping to maintain the chemical integrity of tooth structure. The first generation of this class of composites can be placed with or without a bonding agent and is delivered via a dual-barrel, automix syringe

Non carious cervical lesions (NCCLs) are the cynosure in clinical dentistry, especially among clinical practitioners because of their increasing prevalence. 

Restoring such lesions is technique sensitive and may lead to failure of cervical adhesive restorations due to a variety of factors like, poor isolation, cusp movement during occlusion or adhesion to different substrates (enamel and dentin/ cementum).

A variety of materials are available for restoring class V lesions, like Glass ionomer cement, resin modified GIC and composite resin. Out of these, the most popular restorative material is composite resin due to its esthetics and strength. However it has a drawback in the form of polymerization shrinkage, which is the main reason for marginal gap formations and subsequent marginal leakage.

Bioactive restorative materials are a relatively new concept in dentistry. They are reported to release more fluoride than glass ionomers. Additionally, they react to pH changes in the mouth by uptaking calcium, phosphate, and fluoride ions to maintain the chemical integrity of the tooth structure. Activa Bioactive restorative (Pulpdent, USA) is one such restorative material which comprises of a patented bioactive shock-absorbing rubberized ionic-resin (Embrace resin) matrix that contains a small amount of water. It contains no Bisphenol A, Bis-GMA or BPA derivatives. This class of composites is delivered via a dual-barrel automix syringe and can be placed with or without a bonding agent. However, as per the manufacturer, it is advisable to use a bonding agent in cases of additional retention, like in class V lesions.

There is a constant ongoing research towards the development of an ideal restorative material as well as new adhesives to reduce the microleakage & enhance the bond strength. However, despite the advances in these materials, the marginal integrity, which is the most important feature of adhesive restorative materials, still remains a challenge. 

A substandard marginal integrity can lead to formation of gaps at the tooth- restorative interface resulting in microleakage, which poses serious clinical problems such as, secondary caries, marginal discoloration and hypersensitivity, all of which may result in failure of restorations.
