IVOCLAR Syntac Kit & Refills

Step 1: A dry operating field must be ensured. Ideally, a rubber dam or the user-friendly OptraDam Plus should be used. Step 2: In very deep cavities, areas close to the pulp should be selectively coated with a calcium hydroxide liner (e.g. ApexCal) and subsequently covered with pressure-resistant cement (glass ionomer cement, e.g. Vivaglass Liner). Step 3: Apply phosphoric acid gel (e.g. Total Etch) first to the prepared enamel and then to the dentin surfaces. The etchant should be left to react on the enamel for 15 to 30 seconds, and on the dentin for 10 to 15 seconds. Dentin etching is an optional working step and is not required for Syntac. Following this, remove all etchant gel with a vigorous water spray for at least 5 seconds. Excess moisture should be removed leaving the dentin surface with a slightly glossy wet appearance (wet bonding). Excess moisture should be removed with either air syringe, a dry brush, a foam pellet or other lint-free absorbents. Do not overdry the dentin! Step 4: Apply Syntac Primer with the brush on the cavity and gently rub in. Syntac Primer requires a contact time of at least 15 seconds on the dentin. Step 5: Disperse excess Syntac Primer and dry thoroughly. Do not rinse. Step 6: Apply Syntac Adhesive, leave it for 10 seconds and thoroughly dry the cavity with an air syringe. Do not rinse. Step 7: Apply Heliobond and blow to a thin layer. Note: At this point, Heliobond must be light-cured for direct restorations. For the placement of indirect restorations, Heliobond is polymerized together with the cementation material. Step 8: Light-cure Heliobond for at least 10 seconds with a polymerization light using a light intensity of at least 500 mW/cm2 (e.g. bluephase in the LOP mode). Step 9: Apply the restorative (e.g. Tetric EvoCeram) or cementation material (e.g. Variolink II) according to the instructions of the manufacturer. Note: Do not mix Syntac Primer and Syntac Adhesive. Apply the products sequentially
