The effect of archwire vibrations on the stick-slip behavior of the bracket-archwire interface utilizing clinically relevant tipping moments
(University of Missouri--Kansas City, 2011-07-27)This study evaluated bracket-archwire frictional resistance as a function of ligation method and archwire vibration. In vivo archwire vibrations were measured to obtain frequencies and amplitudes for ex vivo testing. ... -
The effect of simulated oral and clinical conditions on the fracture strength of ceramic bracket tie-wings
(University of Missouri--Kansas City, 2011-08-12)This study examined the effect of simulated oral and clinical conditions on the tie-wing fracture strength of a polycrystalline and a monocrystalline bracket. Fracture strength was measured for brackets as-received ... -
Isopropyl alcohol to counteract effects of freezing on extended-storage alginates
(University of Missouri--Kansas City, 2011-07-08)The purpose of the study was to evaluate the effects of freezing and isopropyl alcohol (IA) on two extended-storage alginates. Impressions were made of a custom stainless steel model of known dimensions and stored for ... -
Quality and intensity of pain associated with continuously applied orthodontic stresses of relatively high and low magnitudes
(University of Missouri--Kansas City, 2011-07-21)The purpose was to assess longitudinally pain intensity and quality during tooth translation by 2 continuous stresses. Eight subjects (five males, 3 females) who required maxillary first premolar extractions had maxillary ...
