ObjectiveTo investigate the initial mechanical environment (ME) changes in root surface, periodontal ligament (PDL), and alveolar bone due to two treatment strategies, low or high moment‐to‐force ratio (M/F).
Setting and Sample PopulationIndiana University‐Purdue University Indianapolis. Eighteen patients who underwent maxillary bilateral canine retraction.
Material and methodFinite element models...
Nearly fully dense (>96% theoretical maximum density) powder mixture compacts with combinations of Nb, Ni, Mo, W, and Ta, with Al, were produced by explosive consolidation. The quasi-static and dynamic behavior and failure mechanisms were investigated experimentally and computationally. For two mixtures (Ni+Al, W+Al) the Al phase was continuous, while for the other three mixtures (Nb+Al, Ta+Al,...
