Is there any difference between conventional, passive self-ligating and active edgewise self ligating brackets a systematic review of the literature and network meta analysis.Yves G. Bolender. Episode 36. IOC 2020

Systematic review:

Significant findings favour self ligating

1. Time to tie an archwire: 107 seconds (CI 95%: -111 -103)
2. Time to remove an archwire: 23 seconds (CI 95%: -27 -18)
3. Bleeding on probing (at 4 weeks): -0.10 (CI 95%: -0.12 – -0.08)
4. Expansion inter-canine width: 0.5mm (CI 95%: -0.91 – -0.11)

Significant findings favour conventional ligating

1. Pain perception (in 19x25SS): 18 (CI 95%: -5.4 -31.1)
2. Expansion inter-molar width: 0.5mm (CI 95%: 0.07-0.94)

Significant findings in favour of active self ligating

1. Time to align mandibular teeth: 10 days (CI 95%: -17.8 -2.3)

Non significant finding

1. Treatment duration: 0.94 (CI 95%: -0.39-2.26)
2. Total number of appointments: 0.35 (CI 95%: -0.67-1.36)
3. Time to align mandibular teeth: No difference Vs conventional ligation 55 days (CI 95%: -122-232)
4. Reduction in irregularity: 0.10 (CI 95%: -0.7-0.5)
5. Speed of space closure: -10 (CI 95%: -0.31-0.11)
6. Pain perception in alignment
7. Bracket failure rate: -47 (CI 95%: 0.58-3.79)
8. Treatment outcomes: PAR / ICON
9. IMPA: -25 (CI 95%: 1.05-1.56)
10. Root resorption: -05 (CI 95%: -2.60- 0.50)
