GC EXA’lence

Advantages
With EXA’lence GC takes dentistry to a new level by solving a number of common problems related to impression taking. With distinctively predictable impressions under all conditions, EXA’lence represents the next generation impression material.

History of elastomeric impression materials

Polysulfide – first elastomeric impression material

C-Silicone – snap set, elasticity

Polyether – Hydrophilicity

A-Silicone (VPS) – dimensional accuracy

VPES™ – a new generation is here

EXA’lence possesses high elasticity and tear strength, combined with constant hydrophilicity and exceptional flow – the result being one of the most accurate impressions obtainable in the market today. EXA’lence is predictable in an unpredictable environment and virtually eliminates the need for retakes.

EXA’lence takes dentistry to a new level with distinctively predictable impressions:

• Intrinsic hydrophilicity to capture the finest details, even in a moist environment
• Outstanding flow and thixotropic characteristics to capture all details and clear crisp margins
• Superior elasticity with a high degree of toughness to resist tearing
• Pleasant mint taste
• Wide choice of setting times and viscosities

EXA’lence solves three common problems related to impression taking:

Inability to control bleeding or crevicular fluid from the prepared teeth

Solution: The inherent hydrophilicity and wettability of EXA’lence will enable you to capture the finest details of the tooth surface, even in a moist environment.

In traditional VPS materials, a surfactant is added that makes a hydrophobic material act in a hydrophilic manner. The surfactant actually leaches out when it comes into contact with moisture, which may cause poor flow, gaps or bubbles.

Surface active agents are released from the surface during setting.

Clinical consequence: during intra-oral setting hydrophilic A-silicone is repelled from moist surfaces.

In GC’s new VPES™ material, hydrophilicity occurs during the material setting time, which allows it to capture all the finest details.

New chemistry avoids diffusion of the fully integrated hydrophilic component.

Clinical consequence: during intra oral setting EXA’lence is attracted by the moist surface and comes into close contact with the tooth surface.

The tension test shows the hydophilicity of EXA’lence as from extrusion out of the cartridge, compared with traditional VPS materials which repel the water.

Voids or folds (fins) caused by poor hydrophilicity or poor flow

Solution: EXA’lence has outstanding flow and thixotropic characteristics to allow the material to flow deep into the sulcus to capture all details and clear crisp margins.

Tearing of the margin occurs during the removal of the impression from sub-gingival areas

Solution: EXA’lence provides a superior elasticity with a high degree of toughness to resist tearing. The impression is easy to remove without tearing in the sub gingival area and the outcome is a precise impression around the gingival area.
