Ivoclar Vivadent Compoglass F - Manual (Page 2)

2. Isolation
Appropriate isolation is required, preferably with a rubber dam
(e.g. OptraDam
® Plus).
3. Cavity preparation
The cavity is prepared according to the principles of the adhesive technique,
i.e., by preserving as much of the tooth structure as possible. Do not prepare
sharp internal edges or angles or additional undercuts in caries-free areas.
The dimensions of the cavity are generally dictated by the extent of the
caries or the size of the previous restorations. Bevel enamel edges of ante-
rior teeth. In the posterior region, only the sharp enamel edges should be
rounded. Do not prepare caries-free cervical defects. Clean them with
pumice or a suitable cleaning paste (e.g. Proxyt RDA 36, medium) and with
the help of rubber polishers or rotary brushes. Ablate sclerotised dentin
around the tooth neck in a thin layer with a rotary instrument (diamond
finisher, coarse disc). Subsequently, rinse the cavity with water to remove all
the residue and dry it with water- and oil-free air.
4. Pulp protection / Base
Do not apply a base if an enamel-dentin bonding agent is used. In very
deep cavities, areas close to the pulp should be selectively coated with a
calcium hydroxide liner (e.g. ApexCal) and subsequently covered with pres-
sure-resistant cement (glass ionomer cement, e.g. Vivaglass
® Liner). Do not
cover the remaining cavity walls so that they can be used to generate a
bond with an enamel-dentin adhesive.
5. Apply matrix / interdental wedge
Use a wrap around matrix for cavities affecting the proximal area or a
sectional matrix and wedge it.
6. Conditioning / Application of the bonding agent
Condition and apply the bonding agent according to the instructions for use
of the product in use. Ivoclar Vivadent recommends using the self-etching
adhesive AdheSE
® One F, for example.
7. Application of Compoglass F
– In order to achieve optimum results, Compoglass F should be applied in
layers of max. 3 mm (light shades) or 2 mm (dark shades = 340/A4 and
540/-) and adapted with the suitable instruments (e.g. OptraSculpt). Use
a special contact point instrument (e.g. OptraContact) for large cavities
where contacts are difficult to create.
– For complete polymerization, sufficient exposure time is required. For
the recommendations regarding exposure time and light intensity see
Table 1.
– Hold the light emission window of the curing light as close to the
restorative as possible.
– When using a metal matrix, additionally polymerize from the buccal or
the lingual/palatal aspect after removing the matrix.
Table 1
8. Finishing / Checking the occlusion / Polishing
After polymerization, remove excess material with suitable finishers (e.g.
Astropol F) or fine diamonds. Remove proximal excess material with flexible
discs, finishing strips or diamond-coated files. Check the occlusion and
articulation and grind in the necessary adjustments to prevent premature
contacts or undesired occlusal paths on the surface of the restoration. Use
silicone polishers (e.g. OptraPol
® Next Generation) as well as polishing discs
and polishing strips to polish the restoration to a high gloss.
Additional notes
1. Use Compoglass F at room temperature. Cold material may be difficult
to dispense.
2. For single use only. If Compoglass F is directly applied from the
Cavifil in the mouth of the patient, the Cavifil should only be used
for one patient for hygienic reasons (prevention of cross-contamination
between patients).
3. Do not disinfect Cavifils with oxidizing disinfectants.
Warning
Prevent any contact of uncured Compoglass F with skin / mucous mem-
brane and eyes. Unpolymerized Compoglass F may cause slight irritation
and may lead to a sensitization against methacrylates.
Commercial medical gloves do not provide protection against the sensitiz-
ing effect of methacrylates.
Storage and hygiene
– Do not use Compoglass F after the indicated date of expiration.
– Expiry date: see note on packaging.
– Storage temperature 2–28 °C (36–82 °F).
– Close Cavifils immediately after usage. Exposure to light causes prema-
ture polymerization.
