Round-end diamonds create chamfer margin and facial reduction for direct and indirect veneer restorations.

Round-end diamonds are the most commonly used burs for facial surface preparation in veneer restorations, both direct and indirect.

They are preferred for several reasons:

- Smoothness:

Round-end diamonds provide a smooth and even surface on the prepared tooth, which is crucial for a good bond with the veneer and an aesthetically pleasing result.

- Precise control:

The rounded shape allows for precise control over the depth and angle of reduction, minimizing the risk of damaging the underlying tooth structure.

- Versatility:

Round-end diamonds can be used for various tasks on the facial surface, including chamfer margin creation, facial reduction, and smoothing out minor irregularities.

Other types of burs may be used in specific situations for veneer preparation on the facial surface, but round-end diamonds remain the most popular and versatile choice.

Additional Details:

Here are some additional details about burs used for veneers:

- Diamond grit:

The grit size of the diamond bur depends on the desired outcome. For initial preparation, a medium grit (e.g., #300) is often used. For finishing and smoothing, a finer grit (e.g., #600) might be preferred.

- Bur size:

The size of the bur will depend on the size and shape of the tooth and the intended amount of reduction. Smaller burs are used for more delicate areas, while larger burs can be used for larger reductions.

- Shank type:

Burs come in various shank types, such as FG (friction grip) and CA (friction grip with latch). Make sure to choose the correct shank type compatible with your dental handpiece.
