What is the primary purpose of burnishers in dental restorations?

The primary purpose of burnishers in dental restorations is to press and adapt restoration margins. Burnishers are specialized hand instruments used to smooth and polish the surface of restorative materials, such as amalgam or composite. This process helps to achieve a better fit of the restoration against the tooth structure, which minimizes gaps and reduces the risk of secondary decay. By adapting the margins effectively, burnishers also contribute to the overall strength and longevity of the restoration.

In addition to pressing and adapting the margins, burnishers can enhance the aesthetics of the restoration by creating a smoother surface, which can improve the gleam and appearance of dental work. The use of these instruments is critical in ensuring that the restoration blends well with the natural tooth and functions effectively within the oral environment.
