In vitro assessment of maximum insertion and removal torque with three different miniscrews on artificial maxilla and mandible

Conclusion It is suggested to perform a pre-insertion drilling due to the higher insertion torque in the posterior mandible, to maintain an acceptable range of maximum insertion torque and achieve primary stability without unnecessary bone damage. It is concluded that the screw design as well as bone characteristics have significant effects on the stability of the screw.
