Summary of Webinar: Simplified Orthodontic Biomechanics with Double Slot Bracket - Thaer Hamid Brazil

Conclusion

New bracket concept, could reduce anchorage demand for specific mechanics

What is it?

· Metal bracket with 2 conventional slots (1 passive, 1 active ligating) in a vertical arrangement

How does it work?

Passive incisal slot 022 x 028

· More liberty between archwire and slot

· Greater force (when compared to 018x025 slot)

Active gingival slot 018x030

· Better rotational control

· Quicker torque expression

Advantage in anchorage and less auxillaries

· Base archwire can be 19x25ss: high rigidity

o active wire can be larger:  16x22NiTi

Archwire sequence

012 CUNiTi initially 1 slot

012 CUNITI Both slots

016 CUNITI Both slots

16x22 CUNITI Both slots

17x25SS (working archwire) in 18x30 slot
