Advancements in dental implant technology: the impact of smart polymers utilized through 3D printing

Abstract

The field of dental implantology has witnessed significant advancements in recent years, driven by innovations in materials science and manufacturing technologies. One such innovation that holds promise for revolutionizing dental implant technology is the integration of smart polymers through 3D printing. This review article provides a comprehensive overview of the impact of smart polymers in enhancing the performance and functionality of dental implants. We begin by elucidating the fundamental properties of smart polymers, including their stimuli-responsive behavior, biocompatibility, and mechanical strength. Subsequently, we explore the evolution and applications of 3D printing, e.g. like direct metal laser sintering (DMLS) and selective laser melting (SLM),  in dentistry, highlighting its role in fabricating customized dental implants. The integration of smart polymers into dental implants is discussed in detail, covering surface modification techniques, incorporation of bioactive agents, and customization for patient-specific needs. Furthermore, we examine how smart polymers contribute to improving aspects such as osseointegration, peri-implantitis management, and overall implant longevity. Clinical insights and case studies are presented to illustrate the real-world applications and outcomes of smart polymer-based dental implants. Finally, this review aims to provide valuable insights for clinicians, researchers, and industry professionals involved in the development and utilization of advanced dental implant technologies.
