RESTOMER l (CEM) is used for cementation of inlays, crown, bridges, facing, orthodontic purpose, cavity linings under amalgam, composite, silicate and acrylic restorations, temporary fillings and deciduous teeth fillings.
mixes to excellent luting consistency
good setting, easy to remove from gingival margins.
adhesive, bi-compatible.
very low sensitivity, kind to pulp
For cementation of inlays, crowns, bridges and facings and orthodontic purposes. For cavity linings under amalgam, composite, silicate and acrylic restorations. For temporary fillings and deciduous teeth filling.
INDICATIONS: Permanent luting cement for crowns and bridges. Strong cavity liner. Strong temporary dressing.
PRESENTATION:
30g Powder
Water dispenser
Mixing Pads
Instructions Sheet
MIXING:
MIXING TIME: 30Seconds
WORKING TIME: 2.30 Minutes
SET TIME: 4.5Minutes from start of mix.
Invert powder bottle a few times to fluff up powder. Level fill powder scoop without compressing powder. Always replace the lid on the bottle after use.
Water bottle should be inverted and squeezed to give required drops of water onto the mixing pads. Initially add first heap of powder and mix to homogeneous paste by using metal spatula. Add rest of powder incrementally until the required consistency. The mixed material should have a glossy surface and is ready for use immediately.
MIXING TECHNIQUE: Tap powder bottle on a firm surface to condense powder. Fill measure scoop to excess without packing, then level off with a spatula. Place powder on mixing pad or glass slab.
Hold water bottle in a vertical position and dispense the number of drops required. Squeeze the bottle and thus release pressure after each drop separates from the bottle.
FOR CEMENTATION: 2 scoops of powder and 2 drop of water.
The ratio for test purposes is 3.45-3.65 Powder: 1.00gm of water at an ambient temperature of 23°C +1°C.
Incorporate powder rapidly into the liquid and mix to a smooth consistency within approximately 30seconds. The mix gives a working time of approximately 3 minutes at 23°C+ 1°C and it should be applied immediately on completion whilst it has a glossy surface. Do not use the cement after it has set to the stage where it starts to ‘Cobweb’.
FOR LININGS AND FILLINGS: 2 scoops of powder & 2 drop of water.
The ratio for test purposes is 2.00g-2.40g: 1.00g of liquid at an ambient temperature of 23°C+ 1°C.
Incorporate powder rapidly into water and mix to a putty consistency within 30seconds. This mix gives a working time of approximately 2 minutes 30seconds and should be applied immediately on its completion whilst it has a glossy surface.
GENERAL CONSIDERATIONS: Remove excess cement before it reaches a rubbery consistency or after complete setting.
Plastic or stainless steel spatulas are recommended for mixing. It is advisable to wipe the spatula and instruments, clean with a wet tissue under running water immediately after use and before material has set. As with any cements, the addition of more powder or higher ambient temperatures than those specified, results in a reduction of working time. Working time can be extended by using a pre-chilled glass slab.
CAUTIONS: Powder is adhesive and contains Polyacrylic acid.
Spatula and instruments should be wiped clean before setting.
Spillages should be cleaned immediately.
In case of contact with skin, wash with plenty of water.
If contact occurs with eyes, wash with plenty of water & use eye-washers if necessary.
Very fine powder may give rise to dust. It is recommended that lid should be replaced immediately after use.
STORAGE:
Store at normal room temperature in a sealed form.
