Wide-diameter implants (WDIs) were also tested with wide base (WB) abutments. This resulted in four test groups: (1) narrow-diameter implants (NDIs; 3.5 mm) with RB/WB abutments, (2) regular-diameter implants (RDIs; 4.0 mm) with RB/WB abutments, (3) WDIs (5.0 mm) with RB/WB abutments, and (4) WDIs (5.0 mm) with WB abutments.

This study aims to verify whether measuring the implant stability quotient at the abutment level is identical to the value obtained at the implant level. Material And Methods - A retrospective clinical study and an in vitro study were performed. For each study, the implant stability quotient measured at the implant level defined the control groups. The values obtained after the abutment seating composed the test groups, which were divided into three test sub-groups, corresponding to three different multi-unit abutments: straight (MUAS) and 17° angled (MUA17), both with 2.5 mm collar, and 30° angled (MUA30) with 3.5 mm collar. Data was compared by the Wilcoxon signed rank test and Kruskal-Wallis test.
