Area of Science:

• Biomaterials Science
• Nanotechnology
• Oral Biology

Background:

• Titanium dental implants face challenges from peri-implant inflammation and biofilm infections, impacting long-term outcomes.
• Current implant surfaces require enhancement to manage microbial colonization, immune responses, and tissue integration simultaneously.
• Surface chemistry and topography critically influence host-implant interactions, including protein adsorption, cellular behavior, and bacterial attachment.

Purpose of the Study:

• To review mechanobiological principles governing host-implant interactions.
• To examine strategies for engineering multifunctional dental implant surfaces.
• To discuss challenges and future directions for clinical implementation.

Main Methods:

• Review of current literature on surface engineering and biomaterials science for dental implants.
• Analysis of biomimetic approaches, including mechano-bactericidal nanostructured surfaces.
• Examination of host-implant interaction principles and translational challenges.

Main Results:

• Nanostructured titanium surfaces inspired by nature show potential for physical bacterial inactivation while supporting bone growth.
• Multifunctional surfaces can be engineered to be antimicrobial, immunomodulatory, and regenerative.
• Key challenges include ensuring mechanical durability, biological masking, and long-term functional stability of engineered surfaces.

Conclusions:

• Biomimetic multifunctional implant surfaces offer a promising strategy for improved dental implant integration and peri-implant health.
• Further translational and clinical validation is necessary for widespread adoption.
• Alternative materials like zirconia are also being explored for implant applications.
