AB  - OBJECTIVE: To evaluate the force-deflection behavior of six beta-titanium wires 
      using a three-point bending test. MATERIALS AND METHODS: The wires timolium 
      (TIM), titanium molybdenum (ORG), beta titanium (BETA), resolve (RES), titanium 
      molybdenum alloy (TMA), and TMA low friction (TMAL) were adapted into two 
      stainless steel brackets, with no angulation or torque. Both brackets were bonded 
      to an acrylic jig with a 10-mm interbracket distance. A testing machine (Instron) 
      applied deflections of 0.2 to 2.0 mm. Force-deflection diagrams were determined 
      from a passive position to an activation of 2 mm and then during deactivation. 
      Forces of activation and deactivation at a deflection of 1 mm were compared by 
      analysis of variance. RESULTS: Results demonstrated that significant differences 
      (P < .05) in force were observed among wires. During activation, forces for the 
      wires were ranked from lowest to highest as TMAL = TMA = RES<ORG = BETA<TIM. 
      During deactivation, forces for the wires were ranked from lowest to highest as 
      TIM<ORG = BETA<RES =  TMA<TMAL. The wires exhibited similar 
      activation-deactivation diagrams. CONCLUSION: This study revealed significant 
      differences in force during activation and deactivation among the six types of 
      beta-titanium wires tested.
