Special Issue Information

Dear colleagues,

We are pleased to invite you to contribute to a Special Issue of Journal of Functional Biomaterials, titled "Advances in Restorative Dentistry Materials”. This issue aims to explore the latest innovations, research findings, and clinical applications in the field of restorative dentistry materials.

Restorative dentistry is witnessing remarkable progress, driven by continuous advancements in material science and technology. These developments are significantly enhancing the efficacy, durability, and aesthetic outcomes of dental treatments. This Special Issue seeks to gather cutting-edge research and reviews that highlight these advancements, providing a comprehensive overview of current trends and future directions.

Key areas of interest include the following:

  1. Ceramics:
  • The development of new ceramic materials that offer superior aesthetic and mechanical properties;
  • Applications of CAD/CAM technology in the fabrication of ceramic restorations;
  • The long-term clinical performance of ceramic materials.
  1. Bonding:
  • Advances in adhesive systems and bonding agents for improved retention and longevity;
  • Explorations of universal adhesives and their effectiveness across different substrates;
  • Mechanisms of bond degradation and strategies to enhance bond durability;
  • Clinical techniques for optimizing bonding outcomes in various restorative procedures.
  1. Manufacturing Processes:
  • The integration of digital dentistry and 3D printing technologies in restorative dentistry;
  • The impact of CAD/CAM systems on the precision and customization of dental restorations;
  • Innovations in manufacturing processes to enhance the quality and efficiency of restorative materials;
  • The role of nanotechnology in developing high-performance restorative materials.
  1. Composite Resins:
  • Enhancements in the formulation of composite resins for improved aesthetics and functionality;
  • Strategies to minimize polymerization shrinkage and enhance wear resistance;
  • The development of bioactive composites that promote remineralization and inhibit bacterial growth.
  1. Biocompatibility:
  • Assessments of the biocompatibility of new restorative materials;
  • Sustainable practices and the environmental impact of restorative dentistry materials;
  • The use of eco-friendly materials and processes in restorative dentistry.

We believe that this Special Issue will serve as a valuable resource for practitioners and researchers alike, fostering further advancements in restorative dentistry materials.

Multilayer monolithic zirconia, which incorporates polychromatic layers that mimic natural tooth gradients, offers enhanced aesthetics and functionality while reducing debonding risks and improving fabrication efficiency. However, uncertainties remain regarding the fracture characteristics of multilayer monolithic zirconia crowns under occlusal loading, whether composed of uniform or combined yttria levels. The current study investigated how variations in yttria levels and thicknesses affected the optical properties and fracture loads of multilayer monolithic zirconia. Samples of multilayer monolithic zirconia in the Vita A1 shade were used, while employing 3Y (SZ) and 4Y + 5Y (AZ) yttria levels. The optical properties, including the color difference (ΔEWS) and translucency parameters (TP00), were measured using a digital colorimeter. The fracture loads were analyzed using a universal testing machine, and fractured surfaces were examined under a stereomicroscope. Statistical analyses assessed the impacts of the yttria levels and sample thicknesses on the optical properties. The ΔEWS values of SZ ranged 3.6 to 4.0, while for AZ, ΔEWS at 0.5 mm was 3.9 and <2.6 for other thicknesses. The TP00 values decreased with an increased thickness, with AZ generally exhibiting greater translucency than SZ. In the fracture load investigations, SZ (>1600 N) generally exceeded AZ (>1260 N), with fracture loads notably increasing with thickness, particularly for premolars (SZ > 3270 N, AZ > 2257 N). SZ predominantly exhibited partial and complete fractures, whereas AZ showed fewer non-fracture categorizations. Complete fractures began with dense, irregular cracks that extended outward to reveal smooth surfaces, while premolars subjected to higher loads exhibited concentric ripple-like structures. Partial fractures revealed radial textures indicative of areas of stress concentration. In summary, higher yttria levels were correlated with increased translucency, while variations in the fracture loads primarily stemmed from differences in the tooth position or thickness. Overall, multilayer monolithic zirconia incorporating combined yttria levels of 4Y + 5Y (AZ) offered high translucency, precise color matching, and substantial fracture resistance, rendering it highly suitable for aesthetic and functional dental applications.
