Zirconomer Improved, a reinforced Glass Ionomer with special zirconia fillers, combines the strength of amalgam with glass ionomer's protective benefits without mercury hazards. It provides sustained fluoride protection, making it ideal for permanent posterior restorations in high-risk patients and cases requiring strong structural cores.
Zirconomer Improved, a reinforced Glass Ionomer with special zirconia fillers, combines the strength of amalgam with glass ionomer's protective benefits without mercury hazards. It provides sustained fluoride protection, making it ideal for permanent posterior restorations in high-risk patients and cases requiring strong structural cores. With superior mechanical properties, including high compressive strength and dimensional stability, Zirconomer Improved ensures long-lasting performance in stress-bearing posterior restorations. Its remarkable translucency, achieved through zirconia nano fillers, offers a natural tooth color match, making it suitable for cores requiring coverage with high-end all-ceramic restorations.
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
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.

Direction to Use :
Preparation: Prepare the tooth for restoration by removing any decay or damaged tooth structure. Clean the tooth and surrounding area thoroughly.
Mixing: Mix the Shofu Zirconomer Improved powder and liquid instructions. The mixing time is typically 10-15 seconds.
Placement: Place the mixed Shofu Zirconomer Improved into the prepared cavity using a suitable instrument. It is important to work quickly as the material will begin to set within a few minutes.
Condensation: Use a suitable instrument to condense the Shofu Zirconomer Improved and ensure it is evenly distributed within the cavity. It is important to avoid overfilling the cavity as this may result in excess material and potential occlusal interferences.
Finishing: Once the material has set, finish and polish the restoration using a suitable polishing system. It is important to avoid over-polishing as this may reduce the material's strength and wear resistance.
