Key Points

To assess how a titanium base affects the passive fit of monolithic zirconia three-unit fixed partial dentures (FPDs) on multi-unit abutments (MUAs).
Implant-supported monolithic zirconia FPDs were evaluated on MUAs with and without titanium bases.
Assessments were conducted to gauge passive fit under clinical conditions.
No significant differences were observed in the passive fit between restorations with and without titanium bases.
The study affirms the clinical reliability of screw-retained monolithic zirconia restorations.

Abstract

The use of a titanium base did not significantly affect the passive fit of monolithic zirconia FPDs on MUAs. The results highlight the clinical reliability of screw-retained monolithic zirconia restorations, both with or without T-base and provides a foundation for future studies involving more complex restorative designs and conditions.
