Dissimilar laser welding of NiTi shape memory alloy to austenitic stainless steel archwires
In this research, dissimilar welding of NiTi shape memory alloy to AISI 304 austenitic stainless steel Archwires was investigated. For this purpose, common straight orthodontic archwire with rectangular cross-section and dimensions of (0.635 × 0.432 mm) were selected and the laser welding technique was used to connect the wires. The microstructure, chemical composition and phasesin the weld zon...

متن کاملComparison of Mechanical Properties between Different Orthodontic Stainless Steel Archwires
Introduction: The Damon system recommended the use of revolutionary, hightechnology Damon edgewise 0.019” x 0.025” orthodontic stainless steel archwires (OSSA) for major mechanics and finishing and claimed that this new archwires offer greater efficiency during orthodontic treatment. No study has been carried out to compare this relatively new archwires to other popular OSSA already in the mark...
متن کاملIncidence of Apical Crack Initiation during Canal Preparation using Hand Stainless Steel (K-File) and Hand NiTi (Protaper) Files
AIM To evaluate the incidence of apical crack initiation during canal preparation with stainless steel K-files and hand protaper files (in vitro study). MATERIALS AND METHODS Sixty extracted mandibular premo-lar teeth are randomly selected and embedded in an acrylic tube filled with autopolymerizing resin. A baseline image of the apical surface of each specimen was recorded under a digital mi...
متن کاملExternal apical root resorption following orthodontic treatment.
This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR. The incidence of EARR was positively associated with tooth position (P < .001), appl...
