 Description

 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.

Key Specifications 

• Working time 1’45”
• Setting time 4’30”
• Shear bond strength (MPa) – Dentin 13.03 ± 3.40
• Shear bond strength (MPa) – Enamel 9.99 ± 3.17
• Compressive strength (MPa) 108

 How to Use 

PREPARATION:

• Prepare tooth using standard clinical guidelines.
• For optimum adhesion, condition the tooth with Riva conditioner (SDI Ltd.)
  for 10 seconds. Rinse thoroughly with water and remove excess water.
• 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 (SDI Ltd.)

MIXING PROCEDURE:

• Paste / Paste ratio (g/g): 2.0/1.0
• Mixing time (min, sec.): 0’15"
• Working time (min, sec.):1,2
• From the start of mixing:1'45"
• Excess cement Tack light cure:5 seconds per surface For tack light curing, use a high power conventional polymerization device
  (460-480 nm)
• Excess cement: Self-curing gel-phase2 1’45” after seating the restoration
• Setting time (min, sec.)2(after seating the restoration): 4'30"
• Radiopacity:1.5 mm Al

Test conditions: temperature (23 ± 1°C, 73± 1°F), relative humidity
(50 ± 10%). ISO 9917-2 2 These times are approximate only and may vary based on storage conditions, humidity, age of the product, and temperature.

• Remove the syringe from the foil pack.
• Remove the cap from the syringe.
• Before each use, dispense a small amount to ensure even dispensing or to remove any dried-out paste. Discard this material.
• Extrude the 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.
• 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
the early setting of the material.

CEMENTATION PROCEDURE:

• Ensure the internal surface of the restoration to be seated is cleaned, dried, and prepared according to the manufacturer’s instructions.
• Apply a thin layer of cement to the bonding surface.
• Seat the restoration within 30 seconds of completion of mixing before any light curing is carried out.
