Hi-Crysta Nano is micro/hybrid light cure
composite. The balance and choice of fillers has achieved an excellent product
in all respects including close to nature shade match. Hi-Crysta Nano
consists of an organic' matrix, which is heavily filled with coupled and
cross-linked with a new generation and 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 luster and finish. For perfectly smooth restoration the
use of clear matrix strips is highly recommended. .
INDICATION: For the restoration of all anterior and posterior
class III, V, IV, I & II.
CONTRAINDICATION: In rare cases (delayed and long term) product may cause
hypersensitivity or allergy in some people. If such reactions are experienced,
discontinue use of the product and refer to physician.
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 is 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.
Sandwich technique: If the cavity is very deep then line the deepest
part of cavity with hard setting Calcium hydroxide liner. Then line the rest of
the cavity with glass-ionomer liner such as Restobase. The liner can be
laid in thick layers reaching the enamel-dentinal junction. This will reduce
the thickness of composite and help to achieve full light core throughout and
also assists in reducing pressure caused by expansions and contraction of
composites. Following this the whole area can be acid etched including the
glass ionomer.
APPLICATION OF HI-CRYSTA NANO NANO:
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.
CURE OF LC COMPOSITES: Each surface of restoration should be exposed for
at least 10 seconds and additional curing should be carried out buccal and
lingual walls. Where pins are in position, it is useful to cure the material around them first
and then re-pack the rest. Use cellophone strip, celluloid crowns and celluloid
cervical matrix, to hold the restoration and cure through these.
CONTOURIPOLISHING/FINISHING: The restoration is easily contoured by fine
fast diamond burs. Composite finishing stones should be used to return the
surface to a smooth finish. The polishing is carried out by using polishing
strips, disc with fine grit Xcem Prophy paste. Final
gloss and seal is achieved by painting glaze onto the restoration.
CAUTION: Hi-Crysta Nano contains resin and diluent/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.
