Silver reinforced glass ionomer restorative, packable like amalgam
HI DENSE contains spherical particles of a silver-tin alloy in a specially developed glass ionomer. This glass ionomer has outstanding physical properties as a result.
Indication
- class I and II cavities in deciduous teeth
- repair of amalgam restored teeth when either tooth or restoration is fractured
- class I and II cavities in selected permanent teeth
- lining under amalgam and posterior composite restorations
- in other classes of cavity when radiopacity rather than aesthetics is a prime requirement
- core build-up material under crowns
- on root surfaces for locating cover dentures
- long-term temporary replacement for cusps
- repair of crown margins
Benefits
- adheres chemically to tooth substance and amalgam
- contains and releases fluoride ions
- low thermal conductivity
- the CTE is close to tooth
- radiopaque, non-translucent
- high compressive strength and hardness
- suitable for use with minimal cavity preparation techniques (MI)
