Bone tissue plays a crucial role
in protecting internal organs
and providing structural support and locomotion of the body. Treatment
of hard tissue defects and medical conditions due to physical injuries,
genetic disorders, aging, metabolic syndromes, and infections is more
often a complex and drawn out process. Presently, dealing with hard-tissue-based
clinical problems is still mostly conducted via surgical interventions.
However, advances in nanotechnology over the last decades have led
to shifting trends in clinical practice toward noninvasive and microinvasive
methods. In this review article, recent advances in the development
of nanoscale platforms for bone tissue engineering have been reviewed
and critically discussed to provide a comprehensive understanding
of the advantages and disadvantages of noninvasive and microinvasive
methods for treating medical conditions related to hard tissue regeneration
and repair.
