Pre-wedging is completed ahead of cavity preparation. In accordance with Lee Ann Brady,10 pre-wedging not only separates the tooth but additionally preserves the delicate tissue.

If your wedge is unfastened, around extension of the material can happen. If there is insufficient wedging force, an open Speak to is acquired. That is contradictory for the studies performed by David Clark11 in which no pre-wedging was accomplished and it led to overhang of restorative content.

In such a case, some Kolar Plus White (Kerr Corporation) was put just after sharpening to re-produce a snow-capped look to the cuspal locations, as noticed on the adjacent natural tooth.
They efficiently slide along with the interdental papilla to take a seat reduced interproximally, permitting for maximum tooth separation whilst also assisting to protect against black triangles [29].
