Abstract

We demonstrate that there was more microstructural damage in cortical bone due to overtightening through deep insertion of orthodontic microscrews than occurred at the lower insertion depth. Extensive osseous microdamage may detract from the stability of immediately-loaded microscrews and implants due to the bone-remodeling processes initiated by microdamage. The subject of just how serious this potential risk is should be addressed in future studies.
