Direction to Use
There are three types of wedging techniques
Wedge Wedging
- In this technique, two wedges are used.
- One wedge is inserted from lingual embrasure area while another is inserted between the wedge and matrix band at right angle to first wedge.
- These are primarily indicated while treating mesial aspect of maxillary first premolar because of presence of flutes in root near the gingival area.
Piggyback wedging
- In this techinique two wedges are used
- One (larger) wedge is inserted as used normally, while the other smaller wedge (piggyback) is inserted above the larger one.
- It is indicated in cases of shallow proximal box with gingival recession.
- This technique provides closer adaptation and contour of the matrix band.
Double Wedging
- One from lingual embrasure and one from facial embrasure.
- Only if middle 2/3 of proximal margin can be adequately wedged.
- When proximal box is wide faciolingually.
