Why is a butt joint cavo-surface angle preferred for amalgam restorations?

Show Answers

Because it enhances both compressive and tensile strengthIt lowers compressive strength but raises tensile strengthIt reduces both compressive and tensile strengthsIt boosts compressive strength along with tensile strength

Explanation

A butt joint cavo-surface angle is chosen for amalgam restorations as it improves both compressive and tensile strength, ensuring better durability and resistance to forces.
