Bioclear TwinRing - For Class II Matrix Adaptation

For Posterior Class II restorations

Custom Tab Content 4

Instructions:

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.
