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
Yes could be increased
