The Directa FenderWedge Small is a component within matrix systems and retraction, categorized under restorative and cosmetic dental supplies. It is engineered for use in direct restorative procedures, providing interproximal separation and protection of adjacent teeth during cavity preparation and material placement.
This specific format is distinguished by its small matrix size, indicated by the orange color. This design is suited for clinicians performing restorative work in areas requiring minimal interproximal space and precise adaptation, such as anterior or smaller posterior teeth. The manufacturer part number is 602751.

About interdental wedges
A wedge is pushed in between two teeth to adapt the matrix to the contour at the gum line, hold it steady and separate the teeth a little. If the wedge is too narrow the matrix will not adapt properly to the tooth surface and a correct marginal seal is not obtained. A wedge that is too wide pushes the matrix beyond the space meant for the restoration and leaves a concavity. Wedges are made of wood, of plastic and of silicone.
A matrix band can be held in place with a wedge, a separation ring, PTFE tape, or block-out or flowable resin, and of those the wedge is the most used for sealing at the gum line and holding the matrix. Protecting the surface of the neighbouring tooth during preparation is described as one of the important biological principles in fixed prosthodontics. Damage to that surface leaves the tooth more open to caries, more sensitive to temperature and more exposed to periodontal disease.
What to look at when choosing a wedge
Height and width: the correct height and width of the wedge is described as crucial to avoid undesirable effects, and the number of heights and widths on the market is limited. A study reports that in many cases the wedge has to be customised, for example with a bur, to do its job.
How a size gets picked: the same study found no published guide or technique for choosing a wedge, so it is usually picked by eye at the size the clinician believes is about right, often after trying several. Trying several sizes costs working time and raises the risk of damage to the tissue between the teeth.
Overhangs: in one study of bone loss over 25 years, loss beside over-contoured restorations averaged 0.16 mm a year against 0.06 mm beside unrestored teeth.
Wedges and guards that protect the next tooth
One study reported damage in 74 percent of preparations where no protection was used, against 50 percent with a metal matrix band and 46 percent with a wooden wedge. A later study of crown preparations found obvious damage on 16 percent of the far surfaces and 4 percent of the near surfaces when a metal band and a wooden wedge were both applied.
Alongside plain wedges, this shelf carries wedge guards and interproximal protection strips made for that job.
