CMA System
CMA system consists of 4 nickel-titanium rotary endodontic instruments for root canal shaping and retreatment. The use of CMA instruments with an ENDO motor with the “auto reverse” function is advised.
Characteristics
A unique and simple sequence:
The same instruments for shaping and removing filling canal materials.
The same instruments for shaping and removing filling canal materials.
Simplicity:
Only one and
the same sequence
for treatment and
retreatment.
Only one and
the same sequence
for treatment and
retreatment.
The same sequence for:
simple, curved and fine canals of monoradicular teeth and molars.

Advantages
Reassuring and resistant rotary instruments.
Not sharp point:
Respect for canal trajectories.

Short handle (11mm):
Improves access to posterior zones.

Deformation of the instrument visible to the naked eye:
Preventing the instrument fatigue.

Instructions for use
| Speed on treatment | 300 to 400 rpm | |
|---|---|---|
| Torque on treatment | 2 N/cm | |
| Speed on retreatment | 400 to 600 rpm | |
| Torque on retreatment | 2 N/cm | |
| Movement | Progression towards the apex by continuous short and rapid up-and-down strokes, finishing off with a “brushing” movement on the root canal walls. |
