Composition
- BIS-GMA matrix, 59% filler (Barium Aluminum Fluoride glass, highly dispersive silicon dioxide)
Light Intensity Compatibility
- LED curing lights (e.g., Kulzer Translux®) with wavelength max at 460 – 470 nm; light output 1550 – 550 mW/cm²
Curing Time and Thickness Guidelines
- Universal Shades: 20s curing time, 2mm max thickness
- Opaque Shades (Dentine): 40s curing time, 2mm max thickness
Storage Recommendations
- Store below 25°C (77°F), away from direct sunlight
Select an appropriate shade or shade combination prior to placing the rubber dam.
The surface should be cleaned with pumice or a fluoride free polishing paste before restoration is placed. A non-sticking plastic, Teflon coated or gold plated placement instrument (such as the Kulzer Plasmacoat Instrument) is recommended for use in clinically placing, sculpting and shaping the material.
Step 1.Use rubber dam (e.g. Ivory®) or similar protection to prevent from contamination by moisture, blood and saliva.
Step 2. Prepare the cavity according to generally accepted rules for the clinical composite application. Then clean and dry the cavity
Step 3. Pretreatment of the tooth structure with an adequate enamel/dentine adhesive is mandatory (e.g. GLUMA® Bondings by Kulzer). Make sure that no excess remains in the corners of the cavity. Once treated with the adhesive avoid contamination with saliva or blood. The use of a flowable composite material (e.g. Charisma® flowables) allows the creation of a smooth cavity floor and facilitates the adaptation of the filling material.
Step 4. Apply Charisma Smart 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 the Charisma Smart opaque shade “Dentine” first)
Step 5. Polymerise Charisma Smart in thin layers (max. 2 mm)
LED curing light such as the Kulzer Translux® light curing unit or any other blue-light unit (wavelength maximum at 460 – 470 nm; light output of 1550 – 550 mW/cm²). Note-During polymerisation, an inhibited-layer forms on the surface which should not be touched, contaminated or removed during the build-up phase of the restoration. It serves as chemical connection for any subsequent composite layers that are added.
Step 6. Finishing and polishing.
For gross finishing use diamond burs. Fine finishing and shaping is best accomplished with fine-grained diamond stones and multifluted carbide burs. Proximal surfaces may be finished with abrasive strips. A high final polish can be achieved with flexible silicone rubber polishing points, cups, discs or similar. Common composite polishing pastes can be applied with polishing brushes and small buffing wheels if desired
