Question

Which matrix system is used for anterior composite resin or glass ionomer restorations?

Options:
a) Tofflemire matrix system
b) Circumferential matrix system
c) Automatrix system
d) Palodent matrix system
e) Sectional matrix system

Answer 1

The matrix system used for anterior composite resin or glass ionomer restorations is the Sectional matrix system.

Step-by-step explanation:

The matrix system used for anterior composite resin or glass ionomer restorations is the Sectional matrix system. This system is designed to separate the teeth, create tight contacts, and provide proper contour and shape for the restoration. It consists of a metal or plastic matrix band that is placed around the tooth to form a wall, and a wedge that is inserted to create space for the composite or glass ionomer material. The sectional matrix system allows for better control and precision when placing the restoration, resulting in more esthetic and functional outcomes.
