1. Select an appropriate shade or shade combination from the CHARISMA DIAMOND Shade guide prior to placing the rubber dam. This is important because teeth will significantly change colour when desiccated. If the tooth surface being treated is not to be instrumented by a diamond stone, carbide bur, drill or other abrasive instrument, the surface should be cleaned with pumice or a fluoride free polishing paste before the restoration is placed.

2. For ideal results, the use of an Ivory rubber dam (or similar) is recommended to control contamination from the presence of moisture, blood and saliva.

3. Prior to the application of CHARISMA DIAMOND restorative material to the cavity preparation, pre-treatment of the tooth structure with an adequate universal/dentin adhesive is mandatory (e.g. GLUMA® 2Bond, GLUMA® Comfort Bond + Desensitizer by Heraeus Kulzer). Once treated with the adhesive, avoid contamination with saliva or blood.

4. Apply CHARISMA DIAMOND Restorative material in thin layers (max. 2 mm) and adapt carefully to the tooth surface or cavity walls. In case of severe discoloration of the underlying tooth or surface being restored, it may be necessary to mask this by using a thin layer of one of the recommended CHARISMA DIAMOND opaque shades first. To avoid excess translucency and achieve an ideal aesthetic result in the case of large Class IV cavities and anterior tooth reconstruction, it is necessary to utilize a CHARISMA DIAMOND opaque shade in the deepest layers, which can then be covered by the universal and incisal CHARISMA DIAMOND shades.

5-6. Polymerise CHARISMA DIAMOND in thin layers (max. 2 mm) using an acceptable light such as the Heraeus Kulzer Translux Power Blue or any unit with a similar spectrum and light output (>400mW/cm2)

7. After final build-up and polymerization is completed, CHARISMA DIAMOND can then be immediately finished and polished.

8. For gross finishing, use diamond burs. Fine finishing and shaping is best accomplished with fine-grained diamond stones and mutilated carbide burs. Proximal surfaces may be finished with abrasive strips.

9. A high final polish can be achieved with flexible, silicone rubber polishing points such as, cups, discs, or similar. Composite polishing pastes can be applied with polishing brushes and small buffing wheels if desired.
