Guest guest Posted March 5, 2012 Report Share Posted March 5, 2012 Following matrix band placement, a wedge is placed.Following wedging, the teeth will be slightly moved apart. Then the band is burnished against the contact point. This ensures contact between restoration and adjacent tooth once the wedge and band is removed. So if we miss to place wedges it will result in open contacts. Also wedges help to approximate bands to the cervical margins of the cavity. If not cervical margins will be overfilled (especially in mesial surface of upper first premolars where concavity of canine fossa interfere with band adaptation). Hope this helps.
