Dentsply Protaper Retreatment Files. Basic description of the rotary files system for retreatment suggested for the students in our courses, part of the guide for the main systems available in Brazil.
Manufacturer's description:
File for retreatment. D1-D2-D3. D1 is indicated to work in the coronal 1/3 of the canal and has an active tip. D2 and D3 have an inactive tip and work in the middle and apical thirds of the canal, respectively.
- Less chance of fracture. - Allows work in very curved and atresed canals. - Greater economy. - Greater safety for the professional. - Greater efficiency in instrumentation. - Greater durability of the instruments. - Greater speed in treatment. - Less stress for patient and professional. - Lower risk of RSI (Repetitive Strain Injury). - Treatment being performed in fewer sessions (makes room for new patients or subletting the room) = higher revenue. - Can be used easily and safely by general practitioners and undergraduate students. - Easier to learn the kinematics of work - less risk of fracture. - Faster treatment time. - Less stress on patient and practitioner. - Better cleaning. - Less contact of the instrument with the canal walls. - Lower risk of fracture. - Made of Nickel-Titanium: Greater existing resistance, Greater existing flexibility, Greater durability. - Rotatory files (motor-driven): Faster treatment speed, Simplicity of use, Brush movement (same as Gates burs), Mandrel has only 13mm. - Multi-conicity in the same instrument: Each file only works where it is really necessary, Allows the system to have only 8 files, Greater flexibility at the tip and greater resistance at the base of each instrument. - Easier to remove instruments in case of fracture. - Requires no or less recapping. - It has cutting edges with variable helical angle: Greater cutting power. - Adequate space for debris removal. - No screw effect Electro-polished files: Less imperfections on the bond surface. - Exclusive retreatment system.
