Grandio – nano-hybrid composite for anterior and posterior fillings

Grandio is a light-cured filling material combining proven composite and innovative nano technology. Grandio is radiopaque, contains 87 % w/w inorganic fillers (= 71.4 Vol. %) in a methacrylate matrix (BIS-GMA, TEDMA, UDMA) and cures under blue light (halogen or LED).

Grandio is used with a dentin/enamel bond. Grandio is available in syringes and in caps for direct application.

Indications:
– filling class I to V cavities
– reconstruction of traumatically affected anteriors
– facetting of discolored anteriors
– correcting shape and shade for better esthetic appearance
– locking, splinting of loose anteriors
– repairing veneers
– filling deciduous teeth
– core build-up under crowns
– composite inlays

Contraindications:
– Grandio should not be used if the recommended application technique cannot be used or if the patient has a known allergy to any of the ingredients (BIS-GMA, BHT, camphor quinone, UDMA, TEDMA).

Grandio- Application:

Preparation/ shade selection
Clean the teeth to be treated with a fluoride-free cleaning paste. Mark occlusal contact points (posterior area); a minimal separation facilitates the design of the approximal contact and placing of the matrix. Before anaesthesia, moisten the Grandio shade guide and match the shade to the moist, clean tooth in daylight.

Drying
Ensure that the working field is dry. Using a rubber dam is recommended.

Cavity preparation
Generally, cavity preparation should be carried out according to the rules of the adhesive filling therapy, i.e. minimally invasive to conserve healthy tooth substance. Bevel the enamel margins on anteriors and round off the preparation margins on posteriors. Non-carious cervical lesions do not have to be prepared; thorough cleaning is sufficient here. Afterwards, clean and dry the cavity.

Lining
A calcium hydroxide lining should be applied in proximity of the pulp. Place a layer of stable cement over the lining. Due to their fluoride release, glass polyalkenoate (glass ionomer) materials are recommended.

Bond material
Grandio is used in adhesive technique with a dentin/enamel bond. All lightcuring bonding materials may be used. Follow the respective instructions for use with regards to preparation (etch technique) and application.

Application of Grandio
Let the material reach room temperature before application. Place a matrix on cavities in the approximal area. Using translucent matrices is advantageous (smooth surfaces). Apply the chosen shade of Grandio (see shade selection) and adapt it with a suitable instrument. Apply and polymerize fillings of more than 2 mm in layers.

Light-curing
Conventional polymerization devices are suited for light-curing this material. The light output should be a minimum of 500 mW/cm2 on halogen polymerization devices and 300 mW/cm2 on LED devices. The curing time is a minimum of 20 sec per layer, for opaque shades OA2 and OA3.5, a minimum of 40 sec. Hold the light emission tip of the device as close as possible to the surface of the filling. If the distance is more than 5 mm, the curing depth may be compromised. Incomplete curing may lead to discoloration and pulpitis-like complaints.

Finishing
The filling can be finished and polished immediately after removing the shaping aids (e.g. fine or extra fine diamond burst, polishing disc), with cooling provided. The margin of the filling or the entire tooth should be fluoridated as a final step. Grandio can be used for direct and indirect inlays according to customary methods. The physical stability can be improved by the usual external (additional) curing.

Warnings/Precautionary measures:
– No known side effects. Hypersensitive persons may develop sensitivities.
– Phenolic substances, especially eugenol- or thymol-containing preparations interfere with curing filling composites. The use of zinc oxide eugenol cements or other eugenol-containing materials in combination with filling composites should be avoided.
– Fillings exposed to occlusal forces should be checked at least once a year for early detection of changes.

Storage:
Store at temperatures between 39°F – 73°F (4°C – 23°C). If refrigerated, the material must be allowed to reach room temperature before use. To avoid exposure to light and possible polymerization, syringes should be closed immediately after dispensing. Do not use Grandio after the date of expiration.
