Chromasit

SR Chromasit is a pressure/heat-curing micro- ﬁlled veneering material. It features excellent physical properties and provides true-tonature shade effects. The material therefore facilitates the fabrication of lifelike composite veneers.

The consistencies of the various ready-to-use SR Chromasit veneering materials are coordinated and compatible with each other. As a result, SR Chromasit Dentin, Incisal and the various special compounds can be layered without intermediate polymerization.

The combination of the SR Chromasit veneering material with the SR Link or SR Chroma Link bonding system produces long-lasting high-quality results.

Indication

– metal-supported crowns and bridges – fully veneered restorations up to the

second premolar

– metal-supported implant-borne

superstructures – veneers in combination dentures – long-term temporaries in combination with

Vectris

Contraindication

– occlusal veneers on molars – layer thicknesses of less than 1.5 mm in

the occlusal region – alloys containing more than 50% silver

and/or copper – alloys containing more than 90% gold,

palladium and platinum – non-precious metal alloys or titanium with-

out mechanical retention – bruxism

Important restrictions on application

If the following advice is not followed, the success of SR Chromasit restorations may be jeopardized: – Do not apply the material in layers thinner

than the stipulated minimum layer thickness.

– If the polymerization unit is contaminated

(eg lime build-up), the polymerization temperature may fall below the required minimum temperature (115–120 °C / 239–248 °F). If the required temperature is not reached, incompletely polymerized veneers, which are prone to the formation of accrection and plaque, may result.

– If used inappropriately, ultrasonic cleaning

ﬂuids may dissolve the resin surfaces because of their high degree of acidity.

– It is advisable to use a special jet medium

(Al

2O3

) with a grit size of 100 microns at

2 bar pressure for blasting purposes.

– The use of a jet medium with a lower grit

size may result in veneering material chipping off.

Side effects

Systemic side effects have not been reported to date. Allergic reactions may occur in rare cases. Do not use SR Chromasit restorations in patients with a suspected or known allergy to any of the material’s ingredients.

Storage

– Storage temperature: 12–28 °C

(54–82 °F)

– Keep packages in use at room

temperature (18–25 °C / 65–77 °F).

– Store SR Chromasit Fluid and SR Link in

the refrigerator (2–8 °C / 36–46 °F). Once opened, Chromasit Fluid remains usable for six months, if stored in a refrigerator. Possible crystal formations can be dissolved by warming the material up to room temperature.

– Protect SR Chromasit Fluid from

humidity.

– SR Chromasit Fluid may exhibit a slightly

yellowish tinge after some time. However, this does not affect the quality of the Fluid or the veneer.

– Protect the material against direct

sunlight.

– Do not use the material after the expiry

date.

– Keep the materials out of the reach of

children.
