Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Machinable lithium-disilicate ceramic onlay (IPS e.max CAD)
Each participant contributes one randomized molar restored with a machinable lithium-disilicate onlay (IPS e.max CAD). Adhesive luting is performed under rubber-dam isolation using the standardized protocol.
Machinable lithium-disilicate ceramic onlay (IPS e.max CAD)
Single indirect onlay restoration milled from an IPS e.max CAD block and crystallized according to the manufacturer's Instructions for Use, then adhesively luted on a randomized molar under.
Pressed lithium-disilicate ceramic onlay (IPS e.max Press)
Each participant contributes one randomized molar restored with a pressed lithium-disilicate onlay (IPS e.max Press). Adhesive luting is performed under rubber-dam isolation using the standardized protocol.
Pressed lithium-disilicate ceramic onlay (IPS e.max Press)
Single indirect onlay restoration heat-pressed from an IPS e.max Press ingot and then adhesively luted on a randomized molar under rubber-dam isolation.
Machinable composite onlay (BRILLIANT Crios)
Each participant contributes one randomized molar restored with a machinable composite onlay (BRILLIANT Crios). Adhesive luting is performed under rubber-dam isolation using the standardized protocol.
Machinable composite onlay (BRILLIANT Crios)
Single indirect onlay restoration milled from a BRILLIANT Crios block and then adhesively luted on a randomized molar under rubber-dam isolation.
