For Posterior Class II restorations
1. PRE-WEDGE AND PREPARE THE TOOTH
A. Insert the Bioclear Diamond Wedge before cavity preparations. This will stretch the periodontal ligaments providing more working space
and separation for a tight contact once the restoration is complete.
B. Prepare the tooth. Make sure to break the contact using a fine bur or the TruContact Sander.
2. REMOVE WEDGE AND THEN PLACE BIOCLEAR MATRIX INTO THE EMBRASURE
A. Remove the pre-wedge. Then, using
cotton pliers, grip the small tab on
the selected matrix.
B. Slide the matrix into the embrasure space making sure the matrix is centered on the tooth and the tab is towards the occlusal.
3. WEDGE THE MATRIX
A. You can either re-use the wedge used
in the pre-wedging step, or use a larger
wedge for stronger separation.
B. Insert the selected wedge against the matrix.
Check that the wedge has not inverted
the curve of the Bioclear Matrix.
Note: In deep caries cases, use the Deep
Caries Diamond Wedge. Position the
Deep Caries bubble toward the cavity.
4.PLACE THE TWIN RING
A. Open the Twin Ring using the Bioclear
ring forceps just enough to get past the
matrix down to the gingival margin.
B. Release the forceps to clamp the ring
over the top of the wedge and down
against the matrix and teeth. Ensure
that the matrix is between the tines
and the tooth, is not folded inside
the hands of the ring ,and is properly
positioned. Use your fingers to lightly
press on the ring to seat it more fully.
Note: With the tip of opened cotton
pliers, gently adapt the matrix
against the neighboring tooth.
This will create a broad contact.
5. PLACE THE COMPOSITE
A. Using the Bioclear clear posterior matrix allows for 3 point curing.
B. Cure from the buccal, lingual and
occlusal before removing the matrix.
6.REMOVE THE TWIN RING,
WEDGE, AND MATRIX
A. Use the Bioclear Punch Pliers to assist
in the removal of the matrix and wedge.
Squeeze the end of the handle to
open and, upon release, the point
will punch through the matrix.
Store at cool and dry place
