Literature shows more than 90 % of NiTi instruments fracture in the apical third or beyond the curve. Fractured instruments in those areas might be not only frustrating but challenging for those without enough experience in successful removal. Besides the challenge, instrument fracture immediately hinders the clinician from performing further treatment, and thus the outcome of the treatment will be compromised. The majority of clinicians would not want to make an attempt to retrieve the broken file in consideration of possibilities of having procedural accidents during the retrieval attempts mainly because instrument retrieval is considered unpredictable. The disadvantages of traditional instrument removal techniques are excessive removal of dentin, which may result in perforation or ledge formation. If the whole procedure for instrument retrieval can be standardized and simply made predictable, it will become no longer issues for every clinician. Therefore, in the lecture it will be described how to make the instrument retrieval procedure easy and predictable so that every single clinician involved in the mishap can also enjoy retrieving those fractured instruments.
Distinguish easy cases from difficult ones for instrument retrieval.
Explain how to make loosening the fractured instrument in preparation more predictable.
Describe how to make it predictable to remove the fractured instrument in removal attempts.
