Final answer:
Angled Tofflemire and sectional matrices are used to restore buccal or lingual extensions in dental restorations. Angled Tofflemire is suitable for amalgam, while a sectional matrix with a ring system is used for composite restorations.
Step-by-step explanation:
The matrices that can be used to restore buccal or lingual extensions in dental procedures are the angled Tofflemire matrix and the sectional matrix. The angled Tofflemire matrix is designed to fit the contours of the tooth and provide support for the restoration where it extends on the buccal or lingual side. It's typically used for amalgam restorations. On the other hand, the sectional matrix is used with a ring or wedge system to create tight contacts and natural contours for composite restorations.
