NCT06580483

Brief Summary

Methods: 28 patients with bilateral remaining first premolar in the maxillary or mandibular arch were enrolled in the study. Dome shaped preparations of the abutments were performed. The amalgam and composite restorations were randomly assigned to either the right or left remaining premolar; then conventional steps of overdenture fabrication and insertion were accomplished. Patients were followed up for 3 years.

Outcome Measures

Primary Outcomes (2)

  • Wear depth

    For each patient, a scan of the abutments was performed using intra-oral scanner in the day of overdenture insertion and another scan was performed after 36m follow up periods and then both scans are compared

    36 months

  • Survival of the restoration

    Restoration survival was assessed according to the criteria approved by the FDI World Dental Federation (FDI) Scientific Committee in 2007 and the General Assembly in 2008 as criteria specifically developed for use in clinical trials.

    36 months

Study Arms (2)

A tooth (on one side) supporting complete overdenture

EXPERIMENTAL

The tooth is prepared to receive a restoration

Other: amalgam restoration

A tooth (on the other side) supporting complete overdenture

ACTIVE COMPARATOR

The tooth is prepared to receive another restoration

Other: nano-composite

Interventions

An abutment tooth is restored on a side by amalgam plug

A tooth (on one side) supporting complete overdenture

An abutment tooth is restored on a side by nano-composite

A tooth (on the other side) supporting complete overdenture
