Special Issue Information

Dear Colleagues,

Craniofacial defects can arise from various causes, including congenital anomalies, trauma, tumor resection, and surgical interventions. Reconstruction in the craniofacial region presents unique challenges due to the complex anatomy and the need to restore both functional and aesthetic aspects. Successful craniofacial defect reconstruction often requires a multidisciplinary approach to ensure comprehensive evaluation and customized treatment planning to address individual patient needs. Biomaterials play a crucial role in craniofacial defect reconstruction, serving as scaffolds for tissue regeneration or as implants to restore structural integrity. Tissue engineering approaches involving stem cells, growth factors, and bioactive scaffolds hold promise for enhancing tissue regeneration and improving long-term outcomes. These constructs elicit a complex biological response upon implantation. Various tangled signaling mechanisms orchestrate cellular activities essential for tissue repair and regeneration. Different types of cells interact with biomaterials to influence the healing process. Surface properties, such as topography and chemistry, modulate cell adhesion, proliferation, and differentiation. Understanding these molecular mechanisms enables tailoring specific regenerative applications in craniofacial defect reconstruction.

In this Special Issue, we invite contributions that shed light on the molecular mechanisms involved in the successful reconstruction of craniofacial defects. We encourage researchers to submit manuscripts presenting original research findings, review papers, innovative methodologies, and conceptual advances in this field. We aim to investigate and deepen the understanding of the molecular features defining the perfect craniofacial reconstruction model.

Reconstructing the orbit following complex craniofacial fractures presents significant challenges. Throughout the years, several materials have been used for orbital reconstruction, taking into account factors such as their durability, compatibility with living tissue, cost efficiency, safety, and capacity to be adjusted during surgery. Nevertheless, a consensus has not yet been reached on the optimal material for orbital restoration. This study investigates the potential of a hybrid hydroxyapatite–collagen (HAp-COL) material 3D-printed on Ti mesh to be used as an implant for orbital wall reconstruction. HAp-COL powder was synthesized using a high-pressure hydrothermal technique. The powder was further used to 3D-print HAp-COL structures on titanium mesh, with the latter having potential uses in orbital wall reconstruction. Biocompatibility was assessed by evaluating the effects of the HAp-COL material on the adhesion and proliferation of fibroblasts (3T3) and mesenchymal stem cells (MSCs) in culture. In vitro and in vivo results showed that HAp-COL is highly biocompatible and has a good integration of the implant in the bone. The findings reported in this study offer convincing evidence to support the use of our designed HAp-COL for the restoration of orbital wall fractures, with a high level of safety. Full article
