Masserann instrumentation |  |
|
The well established MASSERANN technique for the removal of metal
fragments (posts, burs etc.) from root canals is based on the principle of freeing the obstruction
around its periphery.
One of its many advantages is that the fragment is removed quickly with minimal loss of substance
and without the danger of pushing it further into the canal.

MASSERANN MICRO KIT
« Unbreakable » rotary NITI files are at the origin of a new demand
for devices to remove broken instruments.
The Masserann Micro Kit will be the safety parachute in your dental practice.

 |
 |
• Extraction rapide.
• Reasonably quick operation.
• Little risk of pushing fragment further.
• Minimum loss of tooth substance.
• Minimum weakening of root structure.
• No heat built up.
|
|
1. Open access
Enlarge canal orifice using round bur.
Use Gates drill to create straight access to the fragment.
|
|
2. Clear fragment
Use trepan bur to set free approximately 4 mm of fragment (slow anticlockwise rotation).
Masserann trepan burs can be used either by hand with the short manual handle or with a
reducing contra-angle (300-600 rpm) with attachment system according to ISO 1797-2 standard
(tightly screw with the flat spanner).
|
|
 |
3. Grip & remove fragment
• Slide opened extractor over freed end of fragment.
• Hold extractor firmly in place and turn the screw head until it fragment
is gripped.
• Remove fragment :
-in anticlockwise rotation for all cutting root canal instruments.
-in clockwise rotation for all filling instruments (ex : spiral fillers).
|
Bear in mind that...
• Fragment must always be removed in rotation – never pull out only.
• Direct straight access is a must: Masserann tools are straight.
• Positioning the instruments is most important:
- Use your finger to guide the trepan in the right direction.
- 2 Xrays from different angles will help checking orientation of fragment before and when applying extractor.
Cleaning:
- Immerge in a detergent bath, possibly ultrasonic cleaning bath.
- Cleaning, disinfection and sterilisation instructions for root canal instruments apply to the Masserann instruments.
Sterilization :
- Autoclave - 135°C/2.1 bars (275°F/29psi) – 18 mn minimum under sterilization bag.
