An innovative method to successfully erupt buccally impacted canines in difficult positions, that is, sector III and IV mesial the root of lateral incisors into occlusion, has been described. 3-dimensional retraction spring is fabricated using 0.017 × 0.025-inch Titanium Molybdenum Alloy(TMA) wire 45-degree bends are made simultaneously 2 directions. The first bend given distally starting from ...

The aim of this study was to evaluate the tooth movement efficacy retraction springs made a new β-titanium alloy, “gum metal”, which has low Young’s modulus and nonlinear super elasticity. Using double loop incorporated into an archwire gum metal (GUM) titanium molybdenum alloy (TMA), maxillary anterior teeth were moved distally close extraction space. long-term movements simulated by finite el...

We considered possibilities of an application diffractive free-form optics in laser processing metallic materials aerospace production. Based on the solution inverse problem heat conduction, algorithm was developed that calculates spatial distribution power density irradiation order to create required thermal effect materials. It found use for beam shaping made it possible obtain specified prop...
