The Art of File Retrieval

One of the iatrogenic accidents in endodontic treatment is an instrument fracture within the root canal system. An instrument fracture is very frustrating.
Instrument retrieval is even more frustrating and considered more challenging in endodontics than any other part of endodontic procedure. The recent studies have shown that the instrument retrieval with Terauchi technique was predictable and was significantly more successful as well as more conservative in dentin sacrifice than the traditional techniques. The unique procedures in combination with CBCT for instrument retrieval will be shown and discussed on this course using contemporary concepts.

Course Aims
To date no standardized technique for successful instrument removal has been established. It is very crucial to safely remove a fractured instrument. TFRK (Terauchi File retrieval Kit) has been developed to both minimise dentin sacrifice and the time resquired to remove a fractured instrument and maximise the success without causing iatrogenic events. Learn predictable and minimally invasive techniques to retrieve a broken endodontic file using TFRK method.
