An Alexander System Standard Edgewise
PATTerson MeTAl BrAckeTs Use PArAllel TorQUe To AchIeve sUPerIor resUlTs.
Torque in Slot
PArAllel TorQUe BrAckeTs Slot walls and base walls are parallel. Facial surface and base are parallel.
Torque in Base
Why Is PArAllel TorQUe sUPerIor To TorQUe In sloT And TorQUe In BAse?
Either slot walls and base walls or facial surface and base is parallel, but not both.
ProBleMs WITh TorQUe In sloT
In order to line up slots, bracket bases must vary in height, increasing difficulty and decreasing accuracy during bonding.
BenefITs of PArAllel TorQUe
Slots are always centered over base for easier, more accurate bracket placement during bonding. Archwire force is transmitted directly to center of tooth’s crown.
ProBleMs WITh TorQUe In BAse
Torque in Base brackets stick out further facially increasing the chance for occlusal interference and patient discomfort.
