Cortical bone microdamage produced by micro-osteoperforation screws versus orthodontic miniscrews: an in vitro study

The alternative use of Orthodontic Miniscrew Implants (OMIs), traditionally used for skeletal anchorage, to facilitate micro-osteoperforations (MOPs) for accelerating orthodontic tooth movement has been reported in previous studies. The objective of the present in vitro study was to compare the microdamage generated by OMIs and MOP-purposed screws of similar dimensions in porcine cortical bone.
