In view of the recent innovations and modifications in the mini screws and mini plates it would be clinically useful to know the percentage of success in the secondary insertion?
the success of secondary insertion of orthodontic implant depend on multiple factors which are the cause of failure, site of re-implantation is the same site or other, same implant or other one.
the factors that affect the 2ndary reinsertion success are:
Age, gender, loading time, gingival or bone localization (Maxillary or mandibular cortical plate "anteriorly or posteriorly), diameter and length of the miniscrew, physical properties of screw alloy " type , and number of threads", and torque used during threading of the screw.
