Instructions for use
- Light-curing units should have an output of 450 nm and should be checked regularly. The light intensity should be a minimum of 400 mW/cm². Place the light as close as possible to the material. Observe the manufacturer’s instructions for the light unit.
- To prevent premature curing of the materials, close all packaging immediately after use
- The inner surfaces of silicate ceramic veneer must be etched and silanized prior to cementation. The inner surfaces of composite veneer should be sandblasted prior to cementation. Follow the manufacturer’s instructions.
There are no known side effects to date. Isolated cases of hypersensitivity to components of the materials cannot be excluded.
Interactions with other materials Avoid products that contain eugenol, moisture, and air that contains oil since they can impair the curing of Vitique Esthetic Resin Cement and TECO.
- Determine shade of cement
- Etch silicate ceramic with hydrofluoric acid and silanize
- Etch prepared tooth with phosphoric acid gel
- Apply suitable bonding agent
- Cement veneer
1. After removing the temporary prosthesis, clean the prepared core with fluoride-free polishing paste; in doing so, remove residues of the temporary cementation material, rinse, and dry with oil-free air. Try in the restoration
2. The cement shade is selected prior to placing the rubber dam. The shade of the luting cement is determined using the Vitique Try-In paste by applying it on the fitting surface of the veneer. If correcting the selected shade of the cement, the core and preparation are to be cleaned with water and the try-in is to be repeated with a suitable shade
3. Remove the restoration. Clean restoration and prepared tooth thoroughly with water spray. Note: Any residues of the Vitique Try-In paste can impair the permanent cementation of the restoration.
Note: The silane layer of pre-silanized ceramics is destroyed by the try-in. Following contamination of the silanized surface, clean the surface with acetone or alcohol and re-silanize
4. Ensure that the restoration has been pretreated by the manufacturer (e.g., etching the silicate ceramic with hydrofluoric acid)
5. Dry the etched ceramic with oil-free air. Mix 1 to 2 drops of Vitique Silane Adhesive and Vitique Silane Activator in a 1:1 ratio for 15 sec. Immediately apply a thin layer and leave on for 10 sec. Then carefully blow with a light stream of air.
Note: After contamination with Vitique Try-In Paste, clean the restoration with water spray and dry with oil- and water-free air. Clean the surface with phosphoric acid for 15 sec, rinse, dry and apply Vitique Silane
6. The use of a rubber dam to isolate the working area is recommended. Apply DMG Etching Gel to the prepared tooth; in doing so, start in the enamel and spread to the dentine. The response time is 20 to 60 sec on the enamel and 15 sec on the dentine. Rinse the etched areas for 15 s with water and dry with oil-free air. Do not over-dry the dentine. An even, moist layer should remain on the pre-treated dentine
7. Work the TECO bonding agent generously into the conditioned tooth substance for 20 sec using a microbrush, remove any excess present, and carefully blow using oil-free air until an evenly moist surface remains. Then light-cure for 10 sec with a suitable light unit
8. Apply Vitique Esthetic Resin Cement with the veneer tip in the fitting surface of the restoration without leaving any bubbles. Position the restoration accurately on the prepared tooth using gentle pressure.
Note: By using a tacking tip (light device with max. 2 mm diameter) which is set up in the center of the veneer and activated for 1 to 6 sec, the restoration is selectively secured in its position
9. Remove large amounts of excess material using suitable instruments. In the case of very fragile veneer edges, the excess is carefully removed with a brush or dental gauze in the direction of the gingiva. Note: Excess material can be light-cured for 1 to 3 sec using a suitable light unit and can thus be removed more easily
10.Allow each side to harden for 40 sec. Please note that the exposure time depends on the light intensity of the polymerization device used (follow manufacturer’s instructions)
11.Remove excess cured material carefully using suitable instruments and then polish the edges using suitable polishing tips
12.Check restoration for correct occlusal contacts and adjust these, if necessary
13.Mirror-finish polishing of the edges of the restoration can be done with a polishing paste using polishing cups or discs.
