Shofu Zirconomer Improved

Features
High strength and durability like Silver amalgam with protective benefits of glassionomer
Improved edge strength and marginal adaptation
High translucency, flexural modulus and compressive strength
Improved mixing and handling characteristics
Excellent resistance to abrasion and erosion
Remarkable radiopacity
Sustained high fluoride release for anti-cariogenic benefits especially in cases with high caries risk
Exceptional for minimally invasive procedures as it chemically bonds to enamel and dentin while displaying tooth-like co-efficient of thermal expansion, which results in low interfacial stresses and minimizes potential for failure
Packable and condensable like amalgam without the hazard of mercury or the risk of corrosion, expansion and thermal conductivity
For class i & ii, structural base in sandwich restorations, core build-up, root surfaces where overdentures rest, in both pediatric and geriatic cases, as long-term temporary for fractured cusps & fractures amalgam restoratios as well as in ART techniques.

Description
Zirconomer Improved reinforced Glass Ionomer with special zirconia fillers defines a new class of restorative that promises the strength and durability of amalgam with the protective benefits of glass ionomer while completely eliminating the hazards of mercury while proviing sustained fluoride protection. Ideal for a range of restorations including permanent posterior restorative in patients with high risk as well as cases requiring strong structural cores and bases.
Superior Mechanical Properties
Zirconomer Improved outperforms restorative reinforced glass ionomer in stress bearing posterior restorations with notably high compressive strength and dimensional stability for long-lasting performance.
Remarkable Translucency
Zirconomer Improved is formulated with zirconia nano fillers that impart high level of translucency for a closer match to natural tooth colour, ideal even for cores
requiring coverage with high end all-ceramic restoration.

Indications

Class I and II cavities in deciduous teeth
Class I and II restoration in selected permanent teeth
Repair of amalgam restored teeth when either tooth or restoration has fractured
In all classes of cavities where radiopacity is a prime requirement
Core build-up
Repair of crown margins
