Clean the tooth to be treated and adjacent teeth with a brush and prophy paste.
Select the shade using VITA Shade Guide.
Prepare the cavity using conservative cavity technique No residual amalgam or other base material should be left in the cavity.
Cover the area close to the pulp with hard setting CAL-LC Light Cure Calcium Hydroxide paste.
Apply Fusion Bond 7 dentine bonding agent with a disposable brush to the entire cavity. Ensure thorough wetting of the entire cavity. Allow 20 sec air drying and re apply another coat of dentine bonding agent. Remove excess solvent by gently drying with dry air for at least 5sec to ensure uniform glossy surface.
Cure adhesive for 20-30 sec using standard curing light.
Remove Magma NT syringe cap and dispense material onto a mixing pad.
Place the material into the cavity using a suitable placement instrument. Contour the material in the cavity.
Light cure for 40 sec using standard curing light.
When necessary build in increments of 2mm maximum using a layering technique.
Shape and polish with Platina Hi Gloss using standard technique and at last stage apply Nano Coat
