Alumina is
Alumina is aluminium oxide, a hard ceramic used in selected dental crowns, frameworks, implants, and laboratory components.
The short answer
Aluminium oxide is a ceramic, not a metal filling. Its hardness and light colour suit some prosthetic designs, while the indication depends on strength, appearance, and bite.
How should you assess an alumina ceramic restoration?
Ask which ceramic is proposed, how it will be bonded or cemented, and whether the tooth position suits it.
When should you arrange care for an alumina restoration?
Arrange care if a restoration chips, loosens, feels rough, changes the bite, or traps food.
What should you ask before choosing an alumina component?
Ask what alumina component is being used, why it fits, and how it compares with other ceramics.
