Effect of mini-screw maximum insertion torque on skeletal orthodontic anchorage
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 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...

متن کاملEffectiveness of the surgical torque limiter: a model comparing drill- and hand-based screw insertion into locking plates
BACKGROUND The objective of this study is to analyse the effectiveness of the surgical torque limiter during operative use. The study also investigates the potential differences in torque between hand and drill-based screw insertion into locking plates using a standardised torque limiter. METHODS Torque for both hand and power screw insertion was measured through a load cell, registering 6.66...
متن کاملFirst Metatarsophalangeal Joint Arthrodesis: A Retrospective Comparison of Crossed-screws, Locking and Non-Locking Plate Fixation with Lag Screw
Background:Locking plate fixation is increasingly used for first metatarsophalangeal joint (MTP-I) arthrodesis. Still there is few comparable clinical data regarding this procedure. Methods:We retrospectively evaluated 60 patients who received an arthrodesis of the MTP-I between January 2008 and June 2010. With 20 patients each we performed a locking plate fixation with lag screw, arthrodesis w...
