Outcome Measures

Primary Outcomes (2)

  • Retention

    Retention will be assessed by visual inspection and probe to detect debonded crowns.

    1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

  • Fracture

    Fractures will be assessed using visual inspection to detect incomplete fracture lines or complete fractures with loss of crown material.

    1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Secondary Outcomes (1)

  • The gingival condition

    1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Study Arms (2)

Arm 1

EXPERIMENTAL

Zirconia crown cemented with Predicta® Bioactive Cement

Drug: Zirconia crown cemented with Predicta® Bioactive Cement

Arm 2

ACTIVE COMPARATOR

Zirconia crown cemented with resin-cement

Drug: Zirconia crown cemented with resin-cement

Interventions

• For the bioactive cement group (Predicta® Bioactive Cement), the prepared tooth will be dried using compressed air but not desiccated. Cement will be dispensed through the auto-mixtip directly into the crown, and the crown will be properly positioned over the tooth; cement will be allowed to self-set for 20 seconds while maintaining gentle pressure on the crown. Buccal and lingual margins will be flash-cured for 10 seconds each using a light-curing unit to immediately cure the excess cement for easier removal, and buccal and lingual surfaces will then be light-cured for an extra 10 seconds each.

Arm 1

• For the resin-cement group, the tooth will be dried with compressed air but not desiccated. The sealant will be applied with the syringe; then, the crown will be appropriately positioned over the tooth, and cement will be allowed to self-set for 2 minutes and cured while maintaining gentle pressure on the crown. Excess cement will be removed before the cement is completely set.
