Geometrical design characteristics of orthodontic mini-implants predicting maximum insertion torque
OBJECTIVE To determine the unique contribution of geometrical design characteristics of orthodontic mini-implants on maximum insertion torque while controlling for the influence of cortical bone thickness. METHODS Total number of 100 cylindrical orthodontic mini-implants was used. Geometrical design characteristics of ten specimens of ten types of cylindrical self-drilling orthodontic mini-im...
متن کاملThe effect of insertion angle on orthodontic mini-screw torque
BACKGROUND Primary stability is an important factor for the clinical success of orthodontic mini-screws. The present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws. MATERIALS AND METHODS In this experimental study, 72 mini-screws (Dual Top Anchor System, Jeil, 1.6 mm diameter, 8 mm length) were use...

Effect of mini-screw maximum insertion torque on skeletal orthodontic anchorage. ii To my husband Mike whose has always supported me no matter how ambiguous or flighty my life plans have been. Everyday we spend together makes me a better person. iii ACKNOWLEDGEMENTS I would like to thank my thesis supervisor, Dr. Tom Southard, for all his support and guidance throughout my thesis and education....
متن کاملInsertion torque, pull-out strength and cortical bone thickness in contact with orthodontic mini-implants at different insertion angles.
This study aimed to evaluate biomechanical behaviour of inclined orthodontic mini-implants by analyzing its insertion torque (IT), axial pull-out strength (APS), and cortical bone thickness in contact with mini-implant (CBTC). A total of 102 mini-implants were inserted at 90 degree, 60 degree, and 45 degree to the surface of synthetic bone. Peak IT was measured, and the mini-implants were align...
