What purpose do mandrels serve in dental procedures?

Mandrels are specifically designed tools used in dental procedures, primarily serving the purpose of holding polishing discs. This is vital for the finishing and polishing of restorations, such as crowns, bridges, and other dental materials. By securely attaching a polishing disc to a mandrel, dental professionals can efficiently refine the surface of dental restorations, ensuring a smooth finish and optimal esthetics.

The use of mandrels allows for precise control during the polishing process, which is essential for achieving the desired surface texture and shine. An effective polishing process not only enhances the appearance of restorations but also minimizes the risk of plaque accumulation and provides a smoother surface for patient comfort.

Other options do not accurately reflect the function of mandrels. While tooth structure reinforcement, material application, and size measurement are important aspects of dental procedures, they do not involve the specific role of mandrels.
