The archwires are an efficient aid to modify the occlusion plan, by controlling the Spee curve efficiently and optimally. Teeth move farther and faster with lower initial load forces and increased residual forces as full shape recovery progresses
Lower load forces of engagement
• Easier wire deflection and delivery to bracket
• Less stress on bonds
• Increased patient comfort
Higher residual forces of recovery
• Full shape recovery
• Complete unraveling and archform development
• Stays active to the end
