What type of bur is typically used for proximal and lingual axial reduction in partial coverage restorations?

The use of a round-tipped diamond bur for proximal and lingual axial reduction in partial coverage restorations is appropriate due to its design, which allows for a smooth and controlled reduction of the tooth structure. The round-tipped shape enables the dentist to access the contours of the tooth effectively, particularly in areas where space is limited, such as the proximal surfaces. This bur provides a balance of cutting efficiency and safety, minimizing the risk of damaging adjacent teeth or supporting structures during the preparation process.

In the context of partial coverage restorations, which require careful attention to the angulation and contour of the preparation, a round-tipped diamond bur facilitates the preservation of tooth structure while achieving an ideal path of insertion and retention for the restorative material. Its use is particularly beneficial for achieving a well-rounded preparation that promotes optimal adhesion and aesthetics in the final restoration.
