Protaper Rotary Files Sequence Endodontic Rotary Files Systems

Dental Protaper Rotary Files Sequence Endodontic Rotary File Systems

• Unique convex triangle
• Three cutting blades
• Better chip-hold groove
• The cutting edge spacing is gradually increasing, from the tip of the file gradually elongated and thickened
• None-cutting tips reducing andavoiding slop,stairs,apical offset
• Safer, faster,more efficient
• Ni-Ti material with heat re-active ability makes it flexible to reach apical region
• Suitable for small root None-cutting tips
• None-cutting tips reducing and avoiding slop,stairs,apical offset
• Fatigue resident,resisting breaking,flexible
• Corrosion protection

• Build straight canal
• Use 10#,15#K file to find root
• Use open file to open the crown (less depth than 15#k file)
• Measure and make sure working length (use15#k file)
• Use channel file to the work length
• Use 20#file working lengtho
• Use 25# file to working length
• Use 30#file to working length
