        abstract = {Rapid prototyping (RP) and additive manufacturing (AM; commonly “3D printing”) have transformed dental laboratory workflows, offering new approaches for the design and fabrication of fixed partial dentures (FPDs). RP technologies—stereolithography (SLA), digital light processing (DLP), selective laser sintering/melting (SLS/SLM), material jetting and binder-jetting—enable layer-by-layer fabrication of models, patterns, frameworks and definitive restorations. This review summarizes RP technologies and materials relevant to FPD prosthodontics, evaluates accuracy and fit data, discusses clinical workflows and limitations, and outlines future directions including directly printed ceramics and hybrid production routes. Evidence suggests that RP-produced single-unit and short-span FPDs can achieve clinically acceptable marginal and internal fits comparable to conventional and milled restorations in many settings, while larger-span frameworks and long-term mechanical performance remain active areas of research. Practical considerations for clinicians and technicians are emphasized to harness RP safely and effectively in FPD practice.},
