Evaluation of the marginal fit and fracture resistance of interim restorations fabricated using different techniques: an in vitro study.

Background: Interim restorations are essential for preserving structural integrity and function until the definitive restoration is placed. Their mechanical properties and marginal fit are crucial for clinical performance and are influenced by the fabrication technique and material used.

Aim: The aim of this in vitro study was to investigate the marginal fit and fracture resistance of manually fabricated, computer-aided design and computer-aided manufacturing (CAD/CAM) milled, and CAD/CAM three-dimensionally (3D) printed 3-unit interim fixed dental prostheses (FDPs).
