IVOCLAR Vivaglass CEM PL Assortment Kit

Preparation a) Condition the restoration according to the instructions of the manufacturer (e.g. sandblast contact surfaces of metal restorations). If necessary, degrease with alcohol or acetone. b) Coat dentin areas near the pulp with a calcium hydroxide liner. Clean the prepared teeth with prophy paste (e.g. Proxyt ®); rinse with water and dry with an air syringe. Avoid drying out the dentin surface c) Keep the operating field dry with cotton rolls and a saliva ejector. Dosing/Mixing The mixing ratio for a crown is as follows: 1 drop of liquid and 1 scoop of powder (corresponds to a weight ratio of 3:1). For the cementation of a bridge, the material quantities are multiplied by the number of abutment teeth. Dispense powder and liquid next to each other on a mixing pad or a glass plate. Hold the bottle containing the liquid perpendicular when dispensing and squeeze gently to extrude one drop. Shake the powder before use. Overfill the measuring scoop with powder and wipe off excess on the plastic insert in the bottle neck. Close the powder bottle and the liquid bottle carefully after use. On the mixing pad, mix the powder and liquid to a homogenous, creamy consistency with a plastic spatula Working and curing times (WT/CT) Working Time 2 min Curing Time 4 – 6 min At room temperature (23 °C ± 1 °C / 73 °F ± 1 °F), the following times apply after mixing (mixing time approx. 30 sec): Higher temperatures decrease the working time; low temperatures increase it Cementation Place Vivaglass CEM PL in the restoration and apply the material to the restoration walls with a spatula. Introduce it into the root canal using a lentulo spiral or apply it to the orthodontic band. Excess material must be applied in every case. – Place the restoration applying light pressure (e.g. with a condenser). – During setting, the restoration should be kept seated with firm pressure. – Remove excess cement prior to complete setting of the cement, e.g. using a curette. If a retraction cord has been used, it should be removed at this time.
