The self adjusting file system / Dr.sarah alkhateeb

SAF generate minimal reactional force and resulted in minimal dentin removal and this could result to the reduction of fracture risk and dentinal defect

It also all the details of this lecture you can lesson to them in my channel Dr. Sarah alkhateeb https://www.youtube.com/watch?v=YZ66xpoQ5rc&t=28s

1. The self adjusting file system Done by: Dr sarah abd alsalam Supervised by: Dr Ban

2. Rotary nickel titanium were first introduced clinically in 1993 in represent a real shift in endodintic New design have been introduced over the years attempting to make these instrument more efficient, more flexible and safer in the term of file seperation

3. Current rotary file systems are effective tools. Nevertheless they have two main shortcoming:- A- They are unable to effectively clean and shape the oval canals and depend too much on irrigant to do cleaning B- The long term survival of the tooth is by unnecessary excessive removal of dentin and creation of microcrack Current rotary file systems are effective tools. Nevertheless they have two main shortcoming:- A- They are unable to effectively clean and shape the oval canals and depend too much on irrigant to do cleaning B- The long term survival of the tooth is by unnecessary excessive removal of dentin and creation of microcrack

4. Is a shaping and cleaning system designed for minimally invasive endodontic treatment Self adjusting file system

5. The new SAF technology uses a hollow compressible Niti file, with no central metal core , through which a continuous flow of irrigant is provided

6. The SAF has lattice like design makes the instrument extremely flexible in all three dimentions to fit the cross section of the canal at any vertical location

7. The SAF is the first file that does not have a solid metal shaft is designed as a hollow tube with rough outer surface

8. This technology uses a new concept of cleaning and shaping in which a uniform layer of dentin is removed from the root canal thus avoiding unnecessary excessive removal of dentin

9. The SAF allow for effective cleaning of all root canals including oval canals, thus allowing for effective disinfection and obturation of all canal morphologies

10. The SAF is avaliable in three standard lengths ( 21mm,25mm,31mm ) and two diameters ( 1.5mm,2.0mm )

11. 1- SAF System:- include the VATEA peristaltic irrigation device and RDT hand piece The SAF operated with any of two system

12. RDT hand piece operates the SAF with 0.4mm amplitude vertical vibration and designed to be operated at 5,000 rpm RDT hand piece

13. RDT hand piece heads the only hand piece that provide the combined motion of vertical vibration and rotation required for proper operation of SAF

14. The RDT hand piece is designed to sustain prolonged exposure to sodium hypochlorite

15. The VATEA system is a self contained fluid delivery unit intended to deliver irrigant solution during endodontic procedure VATEA system

16. The irrigant is delivered via a disposable silicone tube The flow of irrigant toggled by using a foot pedal and the operator can adjust the flow rate by using -/+ push buttons

17. 2- SAF proSystem :- include the endostation endodontic motor The Endostation is a multi functional endodontic motor that enable the user to operate various endodontic system including SAF and all major brands of rotary and reciporcating file

18. The Endostation include peristaltic pump and irrigation system The irrigation system are operated by foot pedal

19. A large LCD screen and audio are used to indicate the flow rate , working time and battery status

20. SAF in obturation

21. SAF in retreatment

22. When comparing with other rotary system there is economic value thanks to the SAF because of the additional clinical benefits including avoidance of post operative pain, highly efficient endo treatment, the ability of improved cleaning and disinfection in short time with less risk and less complication

23. Thank you
