In-Depth Information
The success of TADs also depends on other factors like proper initial mechanical stability and
loading quality and quantity. Clinically there are difficulties encountered in the removal of TADs
due to increased osseointegration even on the smoother surface TADs. Therefore, it is postulated
that the balance lies in the fabrication of an ideal surface that could stimulate initial osseointegra-
tion and facilitate its removal once the TAD is no longer needed. Biocompatible coatings like tita-
nium nanotubes should be studied to evaluate if the nanotubular layer can enhance initial
osseointegration and can serve as an interfacial layer between the newly formed bone and the TAD.

Conclusions
The applications of nanotechnology and nanoparticles have offered the biomaterial scientists the
opportunity to fabricate materials with improved physical and mechanical properties. The field of
dental biomaterials is constantly evolving. The addition of such nanoparticles to currently available
materials enhances their properties and clinical use. The applications of nanotechnology in ortho-
dontic materials have been reported in the literature over the past few years. However, the number
of studies specifically addressing orthodontics and nanotechnology are small. The authors expect
that the next decade will bring an increase in the amount and quality of research that will help
unveil the next generation of nanomaterials for orthodontic treatment. There are many avenues yet
to be explored that would help move MEMS/NEMS based systems in orthodontics from the draw-
ing board to the bench top and clinical study arena. The utilization of nanoparticles for improving
the TADs should be one such avenue.
