Functional Scaffolds for Hard Tissue Engineering and Surgery

Dear Colleagues,

Hard tissue engineering is a rapidly advancing research field in frame of biomaterials engineering and regenerative medicine that seeks to restore or replace hard tissues—such as bone, osteochondral interfaces (and other skeletal tissues like cartilage, ligaments and tendons), enamel, dentin (and accompanying soft tissues like dental pulp and periodontal ligaments)—through the development of biomaterial-based, often cell- or biofactor-loaded three-dimensional porous implants/scaffolds. These scaffolds are designed to be surgically implanted (during surgical treatments used in hard tissue surgery, i.e., the orthopaedic surgery, the craniofacial surgery, the maxillofacial surgery, and the oral surgery) to regenerate load-bearing structures, repairing both their mechanical function and biological continuity. In reconstructing defects that exceed the tissue’s innate regenerative capacity and in repairing complex osteochondral interfaces—a persistent clinical challenge—engineered scaffolds serve as temporary templates that guide new tissue formation while providing mechanical support under physiological loads. Recent advances in biomaterials chemistry and engineering, biofunctionalization, and additive manufacturing now enable the creation of scaffolds with graded microarchitectures, multi-material compositions, and programmed release of bioactive cues, allowing for designs that better mimic anatomical gradient biostructures, control cell behavior, and synchronize tissue degradation with new tissue formation. Beyond osteoconductive microarchitectures, current efforts focus on scaffolds that provide a 3D microenvironment capable of actively instructing repair (osteoinductive, angiogenic, immunomodulatory), preventing or treating infection (through intrinsic antimicrobial features or local drug delivery), and addressing adjunct needs such as localized cancer therapies or enhanced vascular ingrowth.

This Special Issue aims to exhibit and discuss the latest advancements in functional scaffolds for hard tissue engineering and surgery, including design strategies, new biomaterials, fabrication methods, biological functionalization, and preclinical or translational studies that link scaffold parameters to functional outcomes under clinically relevant mechanical and biological conditions. It is our pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are welcome.

Potential topics include, but are not limited to, the following:

• Approaches to functionalize scaffolds for biological activity;
• Development and characterization of functional scaffolds for hard tissue engineering and surgery;
• New biomaterials and bioactive factors for hard-tissue repair;
• Fabrication methods (conventional and additive) and design workflows;
• Infection control and controlled drug delivery from scaffolds;
• In vitro and in vivo validation of functional scaffolds.
