Efficiency of root torquing auxiliaries.

摘要: In an experimental typodont study simulating the third stage of Tip-Edge treatment, effect five torquing auxiliaries on upper four incisors was assessed using method laser reflection. The analysed were: (1) Two-Spurs 0.016", (2) Four-Spurs (3) Reciprocal Lateral Torque (4) Bar 0.022x0.018", 20 degrees, and (5) 0.022x0.018, 30 degrees. When comparing wires, efficiency (amount speed root tipping) varied considerably: wire most efficient auxiliary tested showed good torque central incisors. acting all less than wire. exhibited palatal labial lateral Bars (20 degrees ) were least wires only small effects incisor teeth. clinical work technique, should be choice for
