SELF LIGATION www.speedsystem.com 2 Activa - 1986 (Passive) Design Characteristics Rotating circular component formed a rigid outer wall that retained archwire in archwire slot. Ligating member incapable of cooperating with the archwire to facilitate corrective tooth movement. Vertical slot for auxiliaries. Clinical Acceptance Heavy promotion by the manufacturer in the 1980's resulted in this design receiving much attention. Initial interest in this design was widespread, but its use was limited by its bulky design and poor clinical performance. The bracket was eventually taken off the market. Smart Clip - 2004 (Passive) Design Characteristics Flexible Nickel Titanium "c" clips which flex open to permit both archwire insertion and archwire removal. The clips also serve to retain the archwire in the archwire slot. Clinical Acceptance Clinical use of this design is growing as interest in selfligating designs increases. InOvation R, C - 2000 (Active) Design Characteristics Curved flexible component forms a flexible outer wall that retains archwire in archwire slot. "Elgiloy" ligating member capable of cooperating with the archwire in corrective tooth movement. This design features "tiewings". Clinical Acceptance Clinical use of this design is growing as interest in selfligating designs increases. Damon I, II, III, MX, Q - 1997 (Passive) Design Characteristics Flat rectangular component forms a rigid outer wall that retains archwire in archwire slot. Ligating member incapable of cooperating with the archwire in corrective tooth movement. This design features "tie-wings". Clinical Acceptance The various Damon designs are all very similar in clinical performance. Clinical use of this design is growing as interest in self-ligating designs increases. Mobil Lock - 1980 (Passive) Design Characteristics Circular component of variable thickness formed a rigid outer wall that retained archwire in archwire slot. Ligating member incapable of cooperating with the archwire to facilitate corrective tooth movement. Ligating member able to “lock” the bracket to the archwire. Clinical Acceptance Based on the design of a movable/re-usable archwire hook. After gaining very limited clinical acceptance in the early-1980’s, this design was virtually abandoned by the manufacturer.
