Ivoclar Vivadent Compoglass F v.2 - Manual (Page 2)

Interactions
Materials containing eugenol/clove oil inhibit the polymerization of
compomers. Therefore, the use of zinc oxide eugenol cements in
combination with Compoglass F should be avoided. Contact with
cationic mouthwashes, plaque disclosing agents, and chlorhexidine
may lead to discolouration.
Application
1. Shade determination
Clean the teeth prior to shade determination. Select the shade
while the teeth are still moist.
2. Isolation
Isolate with cotton rolls or best with rubber dam (e.g. OptraDam ®
Plus), depending on the clinical situation.
3. Cavity preparation
Cavity preparation is done according to the principles of the
adhesive technique, i.e. preserving tooth substance. Do not pre-
pare sharp edges or additional undercuts in caries-free regions.
The cavity geometry is primarily determined by the extent of the
caries or the size of the previous restoration.
Bevel the enamel margins in the anterior region and remove
sharp edges in the posterior region. Do not prepare caries-free
cervical defects. Instead, clean with pumice or a suitable cleansing
paste (e.g. Proxyt RDA 36) and a rubber cup or rotary brush.
Remove a thin layer of sclerous cervi c al dentin, using a rotary
instrument (diamond finisher, coarse-grained disc). Then, remove
all residue in the cavity preparation with water spray. Avoid cont-
amination with saliva following cleaning.
4. Pulp protection / Bases and liners
Only cover very deep areas close to the pulp with a calcium
hydroxide material and subsequently apply a pressure resistant
cement (eg a glass ionomer cement such as 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. Placing the matrix / interdental wedge
If the cavity includes proximal areas, use a wrap-around matrix
(e.g. the selectively thinned OptraMatrix
® ) or a sectional matrix
and wedge it.
The use of a retraction cord or cervical matrix (e.g. Contour Strip)
may be helpful for cervical defects. Rinse the cavity with water
spray and subsequently dry with oil-free air. Avoid dehydration of
the dentin.
6. Conditioning / Application of the bonding agent
Condition and apply the bonding agent according to the Instruc-
tions for Use of the product in use. Ivoclar Vivadent recommends
using Syntac
® bonding agent (in combination with phosphoric
acid etching) or ExiTE ® F (in combination with phosphoric acid
etching) or the self-etching AdheSE ® One F adhesive.
7. Application of Compoglass F
Apply Compoglass F in layers of max. 3 mm (light shades) or
2 mm (dark shades = 340/A4 and 540/–) and adapt with a suit-
able instrument.
Polymerize each layer as indicated in the table shown below. Hold
the light emission window of the curing light as closely as possi-
ble to the surface of the restorative material.
When using a metal matrix, additionally polymerize from the buc-
cal or lingual/palatal after removing the matrix.
8. Finishing / Occlusal check / Polishing
After polymerization, remove excess with suitable finishers or fine
diamonds. Remove proximal excess with flexible discs, finishing
strips, diamond-coated files, diamond or tungsten carbide finish-
ers. Check occlusion and articulation and adapt, if necessary, to
remove premature contacts and undesir ed occlusal paths on the
restoration surface. Polish the restoration to a high gloss using sil-
icone polishers (e.g. OptraPol
® Next Generation), as well as pol-
ishing discs, and strips.
Warning
– Unpolymerized Compoglass F should not come in contact with
skin/mucous membrane or eyes. Unpolymerized Compoglass F
may have a slight irritating effect and may lead to a sensitization
against methacrylates.
– Commercial medical gloves do not provide protection against the
sensitizing effect of methacrylates.
Storage and hygiene
– Do not use Compoglass F after the indicated date of expiration.
– Expiry date: see note on syringe label or package
– Store Compoglass F at 2–28 °C / 36–82 °F
– Once the foil bag has been opened, Compoglass F may be stored
for two months. The material must be used within this period of
time. This applies for syringes as well as Cavifils.
