Hi Crysta is the best of both worlds, hybrid filler for toughness and durability and micro filler for smooth translucent restorations.
Hi-Crysta is a supreme generation of micro/hybrid light cure composite suitable for anterior and posterior applications as part of sandwich technique. The balance and choice of fillers has achieved an excellent product in all respects including close to nature shade match.
Hi-Crysta consists of an organic' matrix, which is heavily filled with coupled and cross-linked with a new generation of high translucency glass filler. The shade match to the tooth is excellent and the LC composite can be polished even though it naturally gives a very smooth high lustre and finish.
Available in both syringe and capsule form
INSTRUCTIONS FOR USE:
Shade selection: Before restoring polish tooth with oil-free Prophy paste and select shade by placing VITA LUMIN against wet tooth in day light or day light corrected lamp.
Please note shade guide in not provided.
Cavity preparation;
Minimal cavity preparation is desirable. Ensure the enamel margins are levelled to maximize acid etching and bonding strength. Ensure all the residual amalgam and old restoration is removed. Before applying bond, isolate tooth and make sure it is kept dry throughout the procedure, as moisture will interfere with bonding and strength of restoration.
Pulp protection: It is advisable to line the deepest part of the cavity with a dot of Calcium hydroxide liner such as Carecal or Calbase LC. Do not use an eugenol based liner.
Syringe: The required amount of LC Composite is removed from the syringe to fill the prepared retentive cavity.
Campules: Load correct shade onto applicator. Ensure that the tip is securely inserted. Using firm pressure extrude composites directly into cavity, taking care to fill from base upwards avoiding any voids. Fill in increments of 3mm and light cure before adding the next layer. Apply controlled pressure to extrude composite. Always ensure the campule tip is correctly seated. If allergy occurs discontinue use.
CAUTION: Hi-crysta contains resin and dilutent/monomer from methacrylate family. Skin allergy, although rare, is a possibility in some individuals. If irritation is suspected, remove composite from skin and wash thoroughly with soap and water. Avoid contact with eyes, if contact occurs, wash immediately with plenty of water.
