1. Wave one gold

2.  The WAVEONE GOLD system is a
single-file and single-use technique.
Through the convergence of an
advanced design, Gold-wire technology,
and a unique reciprocating movement,
preparing canals is now safer, easier
and faster.

3.  Its a new single-file mechanized shaping system.
The WaveOne concept provides a single file shaping
technique, regardless of the length, diameter, or
curvature of any given canal.
 Only 1 file is generally
utilized to fully shape any given
canal.
 Over 4 times safer and almost 3
times faster than using multiple
rotary files to achieve the same final
shape.

4. 3 size WaveOne files
 1. WaveOne Small file (yellow ring): used in fine
canals. The tip size is ISO 21 with a continuous taper
of 6%.
2. WaveOne Primary file (red ring): used in the majority
of canals. The tip size is ISO 25 with an apical taper of
8% that reduces towards the coronal end.
3. WaveOne Large file (black ring): used in large
canals. The tip size is ISO 40 with an apical taper of 8%
that reduces towards the coronal end.

5. File Selection
 # 20 K file or larger
use waveone large
file
 # 10 K file moves to
length easily use
waveone primary file
 # 10 K file very
resistant to move use
waveone small file

6. Features
 Single-file and single-use concept
 Reverse helix; semi-active and modified guiding tip
 Offset parallelogram-shaped cross-section, limiting
the engagement zone
 New supermetal technology termed Gold-wire
 Unique, unequal bidirectional reciprocation movement
 Primary WAVEONE GOLD file is at least 80% more
flexible, 50% more resistant to cyclic fatigue, and
23% more efficient, compared to the original Primary
WaveOne M-wire file

7. Guidelines
• Establish straightline coronal and radicular
access
• In the presence of a viscous chelator, use a size
10 hand file to verify and secure a glide path to
length. In more restrictive canals, use a size 10
hand file in any region of a canal to secure a glide
path
• Expand this glide path to at least 0.15mm,
preferably using Gold Glider
• In the presence of NaOCl, initiate the shaping
procedure with the PRIMARY file

8. • Use gentle inward pressure, and let the PRIMARY file
passively progress 3-4mm through any region of the canal
that has a confirmed glide path. Remove the file, irrigate,
recapitulate and then re-irrigate
• Continue with the PRIMARY file and, in one or more
passes, pre-enlarge the coronal two-thirds of the canal
• Utilize a brushing motion on the outstroke to eliminate
interferences or enhance shaping results in canals that
exhibit irregular cross-sections
• In more restrictive canals and in the presence of
viscous chelator, use a size 10 hand file to negotiate
the terminus of the canal. Gently work this file until
it is completely loose at length

9. • Establish working length, confirm patency and verify the
glide path
• Expand this glide path to at least 0.15mm, preferably
using Gold Glider
• Carry the PRIMARY file to the full working length in
one or more passes. Inspect the apical flutes; if they
are loaded with dentinal debris, then the shape is
finished*
• If the PRIMARY does not progress then use the
SMALL file to working length and, if desired, then the
PRIMARY file to optimize the shape * If the PRIMARY
file is loose at length with no dentinal debris in the
apical flutes, continue shaping with the MEDIUM file
and/or LARGE file until the apical flutes are loaded

10. Technique
 A WaveOne file was used in a reciprocating motion
according to the manufacturer’s instructions using
(WaveOneTM endo motor). The silicon stopper was set on
the WaveOne file at 2/3 of WL.
 Then, the file was introduced in the
canal with a slow in (light apical
directed force) and out
(circumferential brushing) motion
without pulling the instrument
completely out of canal.

11.  After 3 in-and-out movements, the
WaveOne file was pulled out of the canal
to clean the flutes, and the canal was
irrigated.
 The WaveOne file was used until it had
reached 2/3 of the WL as indicated by
stopper on the file. Then the file was
reused in the same manner until the WL
had been reached

13. Advantages
o Reinforces patient safety
o 50% more resistant to cyclic fatigue
o Reduced screwing effect compared to standard rotary
systems Covers a wider range of canal morphologies
o Enhanced file flexibility thanks to the Gold technology
o Extended size range (Small, Primary, Medium, Large)
Shortens the shaping time
o Takes the cutting efficiency to a higher level
o A single file per treatment also translates into time
savings for canal shaping and irrigation
