Mechanical Prep Techniques Flashcards
1
Q
Protaper hand files techniques
A
10k 2/3rds EWL
10k,15k file to CWL (balanced force)
S1 - coronal 3rd
S2 - mid 3rd
SX - auxiliary file to open orifice
F1 - finishing file to CWL
F2 - finishing file to CWL
2
Q
Modified double flare technique
A
10k 2/3rds EWL
GG4,3,2 to 2/3rds
10k-25k CWL
30k until file binds, then take next to 2 file sizes to CWL to create apical stop + decide MAF
STEPBACK
Take 1 size larger than MAF
30k - 14mm
35k - 13mm
25k - 12mm
3
Q
Reciproc deciding file sizes
A
Canal narrow/partially invisible - R25
20k passive to WL - R40
30k passive to WL - R50
4
Q
Reciproc steps
A
10k,15k, R25 2/3rds EWL
10k CWL
R25 CWL
MAF 25k inserted
5
Q
Protaper retx steps
A
500-700rpm
D1 - coronal 3rd
D2 - mid 3rd
D3 - apical 3rd
