AuthorsAbstractFixed prosthodontics has developed significantly due to the development of new high-technological ceramic and hybrid restorative materials, which are intended to balance mechanical reliability with high esthetics and biologic compatibility. Contemporary zirconia and lithium-based ceramics have expanded indications for metal-free restorations, while hybrid and resinmatrix systems have emerged as alternatives designed to modulate stress distribution and facilitate conservative preparation strategies. This review synthesizes current evidence regarding the clinical performance of these materials, focusing on survival and longevity, mechanical and technical complications, biologic response, esthetic stability, and the influence of procedural variables. Available data indicate that advanced ceramics demonstrate predictable performance in load-bearing applications, although complications such as fracture, chipping, and wear remain relevant considerations. Hybrid systems may offer advantages in machinability and reparability, yet long-term comparative clinical evidence is still limited. Restoration outcomes are strongly influenced by preparation design, adhesive and cementation strategy, occlusal management, and digital workflow precision. Despite promising developments, heterogeneity in study design and outcome definitions restricts direct comparison across material classes. Continued long-term prospective research and standardized reporting are essential to refine material-specific indications and strengthen evidence-based decision-making in fixed prosthodontic practice. 1. Introduction The field of fixed prosthodontics has experienced significant development throughout the past few decades, which is dictated by the unceasing progress in restorative materials and concepts of treatment. Modern prosthodontic ideologies are dominated by biologically oriented preparation techniques, adhesive techniques and extended treatment modalities that no longer depend on conventional approaches to metal-ceramic restorations.1 The success of fixed restorations in the long term is closely tied to periodontal health and soft tissue compatibility, which are biologic considerations that are the core of restorative planning and material choice. Marginal adaptation, emergence profile and restorative contours have a direct effect on periodontal response and long- term maintenance.2 The digital workflows of technological developments and the additive manufacturing methods have also increased the restorative opportunities. New types of materials with specific structural and mechanical properties, such as 3D-printed crowns and hybrid prostheses, have been developed.3 Simultaneously, it has produced hybrid ceramics as alternative materials used to restore crowns, which attempt to blend the structural integrity of ceramic materials and the strength of polymer-based systems.4 Other novel inventions in the science of dental material include high-strength zirconia, lithium-based glass ceramics, and improved restorative systems to maximize functional longevity and esthetic integration.5 Innovation in material engineering has also helped in enhancing fracture prevention and long-term service of prosthodontic materials.6 Also, •••••••••••••••••••••••••••••••• ejprd.org- Published by Riset Publishing Services LLC.
