1 M3 –Pro Gold Operating Guide

2 The features of M3 –Pro Gold
The first 4 files, all are taper 4%; the last 2 files, 2506 and 3504, designed for large canals. Can be pre-bent, make sure the files rotate along the canals. M3-Pro Gold files have better resistance on cyclic fatigue. Much safer than traditional files Each file is strictly tested in factory.

3 M3 –Pro Gold Rotary Files
Package:6 pcs/pack with blister packing Open file: #30, 8% (Blue) MP : #20, 4% (Yellow) MP : #25, 4% (Red) MP : #30, 4% (Blue) MP : #25, 6% (Double red line) MP : #35, 4% (Green mark)

4 Is it slow by 6 pcs files sequence?
M3-Pro Gold sequence Familiar sequence Smooth working flow Reduce the risks of the clinical accident

5 The purpose of M3-Pro Gold preparation:
Build a good space and smooth path for canal irrigation and the obturation. The principle of M3-Pro Gold preparation: The final shape of preparation ensures a smooth path and retain the dentin as much as possible.

6 Negotiate the canals by #10 ss. file
Explore the canals carefully by using #10 stainless steel hand files. Measure the working length

7 Negotiate the canal by #15 ss. file
Negotiate the canals to the working length by #15 stainless steel hand files Repeat the negotiation until the size of canal reaches #16-#17.

8 Dr. Ruddle emphasizes BIG THREE:
Every 2 files ❶Irrigate ❷pound the debris with small SS. file, ❸irrigate again

9 It is recommended to irrigate by 5.25% NaClO
It is the core of rotary files operation to fully irrigate and clear the debris It is recommended to irrigate by 5.25% NaClO

10 300RPM, 3.0N 1) Enlarge the apical area of the canal by open files
Reduce the stress from the preparation of next files. Make sure the lubricants can reach the tip of canals smoothly. Keep a good hand feeling for the next files 300RPM, 3.0N

11 350 RPM, 1.5N 2) Build a glide path by using #19 Path Files
The path built by path files is smooth, continuous and concentric. Brush the wall of the canal when using path file reach the work length, to provide more space for the next files. 350 RPM, 1.5N

12 3) MPG-1, #20, 4% (Yellow), prepare to the working length
Lubricate the file’s tip by EDTA. Prepare the canal to working length by brushing motion. Keep brushing all direction of the wall to prepare the size of canal to #21-#22. Then irrigation, negotiation, irrigation with NaClO. 350RPM, 1.5N

13 Dr Ruddle mentioned brushing motion many times in the video, which is the secret of Protaper ‘s success

14 350RPM, 1.5N 4) MPG-2, #25 , 4% (red), prepare to the working length
Lubricate the file’s tip by EDTA. Prepare the canal to working length by brushing motion. Keep brushing all direction of the wall to prepare the size of canal to #26-#27. The preparation can be finished if some posterior have double canals。 Then irrigation, negotiation, irrigation with NaClO. 350RPM, 1.5N

15 5) MPG-3, #25, 6% (double red), prepare to the working length
Be cautious to use the file 6% if the curve over 45 degree! Lubricate the file’s tip by EDTA. Just make this file amplitude strokes with every 1-2 mm instead of brushing motion. Then irrigation, negotiation, irrigation with NaClO. 350RPM, 2.5N

16 350RPM, 1.5N 6) MPG-4, #35, 4%(green), prepare to the working length
Lubricate the file’s tip by EDTA. Just make this file amplitude strokes with every 1-2 mm instead of brushing motion. Then irrigation, negotiation, irrigation with NaClO. 350RPM, 1.5N

17 The finished preparation by M3- Pro Gold
This preparation is finished with 6% taper The path is glide, continuous and without transportation

18 Root canal obturation Cold lateral condensation: 2% gutta percha points are recommended only. 2. Heat gutta purcha obturation: We recommend to use 4% or 6% gutta purcha points

19 More points about M3-Pro Gold files
Build a straight-line access, make sure the files reach the apical or the fist curve with straight line. Relocate the coronal, ensure the lubricants arrives the 1/3 of the apical with the files. Keep the instruments be always lubricant especially at the 1/3 of the apical With short 1-2mm amplitude strokes to avoid the files to stop at one place. Don’t reach the working length one time, ensure irrigate the canal every 1-2mm. Build a smooth and repeatable access by each files

20 How many times the files can be used?
Anterior teeth: 30 canals Posterior teeth:15 canals( or 5 posterior teeth) Tip : One time use only is recommended if the canal is much too curved
