STEP1.Isolation Appropriate isolation is required, preferably with a rubber dam (e.g. OptraDam® Plus).
STEP2.Preparing the metal surface In case of an exposed metal surface, roughen the surface with a diamond or corundum grinding instrument using water irrigation. Alternatively, roughen the metal surface with an intra- oral sandblasting device (observe the instructions of the manufacturer).
STEP3. Preparing the defective ceramic or composite surface Bevel the margins of the defective ceramic or composite surface (1-2 mm) with a fine-grained diamond grinding instrument using water irrigation.Usage.
Subsequently, rinse thoroughly with water and dry with oil-free air.
STEP4.Placing the matrix If the restoration includes proximal areas, place a matrix band and secure it with a wedgeNote: If tooth structure is affected by this repair, these areas must be pretreated with a dentin/enamel adhesive.
STEP5. Monobond N Use a brush to apply Monobond N to the exposed ceramic, metal and composite surfaces and allow to react for 60 seconds. Subsequently, dry with oil-free air. (Do not rinse with water.)Then, light-cure for 10 seconds. (e.g. Bluephase® N ”High Power Program“).
STEP6.Applying Heliobond Apply a thin layer of Heliobond to the entire surface area which needs to be repaired. Remove any excess with compressed air.
STEP7. Applying the opaquer Apply IPS Empress Direct Opaque to the prepared metal surface only. The layer applied should have a thickness of maximum 0.5 mm.Then, light-cure for 20 seconds. (e.g. Bluephase N “High Power Program“). If the surface is still not sufficiently masked, apply a second layer of IPS Empress Direct Opaque and light-cure again.
STEP8.Restoring the restoration with Tetric N-Ceram Apply Tetric N-Ceram in increments of max. 2 mm and adapt the material with a suitable instrument (e.g. OptraSculpt® Pad).
STEP9.Finishing and polishing Remove excess with a suitable fine-grained diamond grinding instrument.Light-cure each layer individually for 10 seconds (e.g. Bluephase N ”High Power Program“).
