Reciproc System file and Rotary System file 1. Higher Cutting Efficiency
Alternating forward and reverse rotation continuously changes the contact angle between the file and dentin, greatly reduces cutting resistance, accelerates removal of dentin debris and shortens clinical operation time.
2. Lower Risk of File Separation
Reverse rotation releases torsional stress and fatigue stress accumulated on files in curved root canals, avoids stress concentration, effectively reduces file fracture and binding, and improves operational safety.
3. Better Root Canal Shaping
The motion mode is gentler with uniform cutting on canal walls. It avoids over-cutting the canal isthmus, apex and curved segments, better preserves the original root canal morphology, taper and trajectory.
4. Superior Canal Negotiation
The reciprocating forward-reverse motion facilitates entry into narrow, calcified and curved root canals. It negotiates blocked fine canals more easily and has a higher success rate for complex canals than continuous rotation files.
5. Less Patient Discomfort
It delivers stable vibration and torque, reduces mechanical irritation inside root canals, alleviates soreness and pain during treatment and improves patient comfort.
6. Longer Service Life of Files
Optimized stress cycle slows down metal fatigue and blade wear of files, so it features better durability during repeated clinical use compared with continuous rotation files. file
