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.
