SDI Riva Cem Resin Modified GIC
SDI Rivacem Resin Modified GIC
Riva cem is a self-curing, radiopaque, fluoride releasing paste/ paste resin modified glass-ionomer luting material. It is indicated for permanent cementation of metal-based and strengthen-core ceramic restorations, and orthodontic appliances.
Riva cem comes with the additional light tack cure option for early removal of excess cement, excellent tooth adhesion, fluoride release and ideal flowability, for your cementation needs. It is available in a universal light yellow shade in double barrel syringe which can easily be hand mixed.

2. Product may cause skin irritations to some people. In such cases, discontinue use and seek medical attention. Any persons having known resin allergies should immediately discontinue use.
STORAGE AND HANDLING :-
Avoid excess heat and direct sunlight.
• Do not remove riva cem syringes from foil packets until ready to use.
• Store between 10°C and 25°C (50° – 77°F).
• If stored at cooler temperature allow product to reach room temperature prior to use.
• Use at room temperature between 20°C and 25°C (68° – 77°F)
• Store with cap securely attached to the syringe. Do not allow the pastes to dry out.
• For professional use only.
• Do not take internally.
• Do not use after expiry date.
• Caution :-
Federal Law restricts this device to sale by or on the order of a dentist.
- 1 x 8.5gms syringe (Universal Light Yellow Shade)
- Available in double barrel syringe which can easily be hand mixed
Direction to Use :-
1. PREPARATION :-
a) Prepare tooth using standard clinical guidelines. b) For optimum adhesion, condition the tooth with riva conditioner (SDI Ltd.) for 10 seconds. Rinse thoroughly with water and remove excess water. c) In cases where pulp protection is necessary, use a calcium hydroxide liner or a resin-modified glass-ionomer liner such as riva bond LC P/L
2. MIXING PROCEDURE :-
a)Before each use, dispense a small amount to ensure even dispensing or to remove any dried out paste. Discard this material. b) Extrude required amount of pastes onto a mixing pad. Important: Ensure the thumb is positioned firmly in the middle of the plunger to obtain the correct dispensing ratio of the two pastes. c) Using a spatula, mix the two pastes together thoroughly for 15 seconds. Be careful not to incorporate air bubbles. Note: Do not expose riva cem paste directly to operatory light to avoid early setting of the material.
3. CEMENTATION PROCEDURE :-
a) Ensure the internal surface of the restoration to be seated is cleaned, dried and prepared according to manufacturer’s instructions. b) Apply a thin layer of cement to the bonding surface. c) Seat the restoration within 30 seconds of completion of mixing before any light curing is carried out.
Note: 1. Avoid overfilling crowns. 2. Room temperatures above 23°C/73°F will reduce the working time. d) Light cure any excess material for 5 seconds per surface using a high power LED curing light (460-480nm emission). e) Gently remove excess material using a scaler or explorer. Note: Excess can also be removed during self-curing gel stage (when cement feels rubbery), after 1 min 45 seconds. f) Maintain isolation for at least 4 min 30 seconds after seating of restoration.
