Engineering the Restorative Future: Bioactive Materials, Biomimetic Concepts, and Digital Transformation in Contemporary Prosthodontics
Abstract
A paradigm shift in restorative dentistry is taking place from passive replacement of lost tooth structure to biologically integrated, biomimetic and digitally engineered restorative solutions. This is a narrative review of the changing face of current restorative dentistry, from a holistic standpoint of bioactive materials and biomimetic principles, advanced prosthodontic biomaterials, and using digital technology. The first part of the review examines how traditional restorative materials and bioactive materials that release ions, remineralize, inhibit the formation of biofilms, and interact with the tooth–restorative interface differs from each other. The first part of the review will examine the differences between traditional restorative materials and bioactive materials that are able to release ions, remineralize, inhibit the formation of biofilms and interact with the tooth–restorative interface. It then reviews biomimetic strategies aimed at maintaining native tooth structure and recreating the hierarchical, mechanical and functional properties of natural enamel and dentin. The modern developments of high-performance ceramics, zirconia, lithium disilicate, hybrid and resin-based ceramics, surface-functionalised and bioactive prosthodontic materials are also presented and discussed with special focus on their clinical applications and limitations. The review also emphasizes the revolutionaries that have taken place with intraoral scanners, CAD/CAM, digital treatment planning, artificial intelligence, computer-aided implant planning, 3D printing, digital occlusal analysis, and digital quality control. The convergence of advanced biomaterials, biomimetic design and digital manufacturing is highlighted as a cornerstone for increasingly personalized and precision-oriented restorative care. Although significant technological advances have been made, there are significant issues related to long-term clinical evidence, mechanical durability, biological safety, interfacial stability, standardization, cost, accessibility, and integration into a routine clinical workflow. The next generation in restorative dentistry will be multifunctional, adaptive and potentially regenerative systems. The incorporation of materials science, biomimicry, digital engineering, and biological considerations could ultimately help to restore tissue, restore natural function, and deliver patient care that is individualized, predictable and harmonious with biology
