Question: 1 / 1775

Inverted cone burs are mainly used for what purpose?

To create mixtures for fillings

To smooth tooth structures

To make undercuts for retention grooves

Inverted cone burs play a crucial role in restorative dentistry, specifically designed for creating undercuts and retention grooves in tooth structures. This design, which has a narrower shaft and a wider tip, allows the dental professional to effectively prepare a tooth for restoration by providing a mechanical retention feature. This is especially important in situations where the restoration material needs to adhere securely to the tooth, preventing it from being dislodged during normal use.

The use of inverted cone burs for forming these undercuts is vital because it enhances the retention of the filling material within the cavity preparation. This ensures a stable bond and longevity of the filling, which is critical for the overall success of dental restorations.
