Clinical Evaluation of Indirect Tooth-Colored Onlays With Cervical Margin Relocation

Two-year Clinical Evaluation of Different Indirect Tooth-colored Onlay Restorations Placed in Posterior Teeth With Cervical Margin Relocation and Laboratory Investigation of Marginal Adaptation

Conditions

Indirect Tooth-colored Onlay Restorations in Posterior TeethClinical Performance of Cervical-margin-relocated Onlay Restorations

Summary

This study will evaluate the performance of three different tooth-colored onlay materials in adult patients' posterior teeth. First, investigators will use a bulk-fill composite resin to raise the cavity margin above the gum line and below the contact point. Then each patient will receive three onlays made from different materials. Investigators will follow patients at 2 weeks, 6 months, 18 months, and 24 months to assess how well the onlays fit, function, and whether restorations cause sensitivity or new decay. The results will help dentists choose the most durable onlay restorations for deep-margin elevation cases.

Eligibility

Inclusion Criteria3

  • Molar tooth with proximal subgingival carious lesion of ICDAS 4 or 5, causing weakening of one or more cusps.

  • Acceptance of the follow-up period and recall visits for 2 years.

Exclusion Criteria11

  • Distance between the gingival margin and the crestal bone < 2 mm.
  • The tooth would require direct pulp capping.
  • Poor oral hygiene (or not completing the oral hygiene phase).
  • Chronic periodontitis.
  • Pulpitis or non-vital tooth.
  • Orthodontic treatment.

Interventions

OTHERMachinable 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.

OTHERPressed 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.

OTHERMachinable 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.
