Clinical Tips: FenderWedge
Protection and Separation


The importance of protecting the adjacent tooth.

Bur damage to neighbouring teeth is sadly a common problem in the everyday dental practice. Research proves that teeth are damaged in more than 70% of all cases during Class II preparations.*

" We all take out proximal fillings and see big bur damage to the approximal surface. We grandly look at them and think how clumsy the previous dentist must have been - but then it happens to us! It is not always our fault however. That enemy, the tongue, can often drive the hand piece and bur straight forward at a critical time, even with the best finger rests. So, if you are like me and accept it may happen, you want to protect the adjacent tooth. I have found the Directa FenderWedge is by far the easiest and most cost-effective protection product to date.

Why should I use FenderMate?

FenderWedge prevents damage to the adjacent tooth and gingiva that can occur during Class II preparations.

FenderWedge is a combination of a steel plate and a plastic wedge. Inserted into the interproximal space, it protects the tissue and separates the teeth thus simplifying the application of a matrix.


How should I use FenderWedge?

FenderWedge can be inserted buccally or lingually for optimal access and vision and is available in four colour-coded sizes. A FenderWedge that requires firm pressure to be inserted will provide better separation and stays in place throughout the preparation.

If the protective plate is perforated FenderWedge should be replaced. Should any damage occur to the plastic wedge during preparation the procedure may be continued, as the protective plate inside the wedge reaches down to the gingiva.

When FenderWedge is removed some bleeding may occur. This is caused by pressure on the tissue.
