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 018×025 slot)

Active gingival slot 018×030

• Better rotational control
• Quicker torque expression

Advantage in anchorage and less auxillaries

• Base archwire can be 19x25ss: high rigidity
• Active wire can be larger:  16x22NiTi

Archwire sequence

• 012 CUNiTi initially 1 slot
• 012 CUNITI Both slots
• 016 CUNITI Both slots
• 16×22 CUNITI Both slots
• 17x25SS (working archwire) in 18×30 slot

Issues: Friction
