NS-2 Predictable and Minimally Invasive Retrieval of Separated Instruments

5 (10 votes)

CE: 1.5

Course Description: 

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. Literature shows that when NiTi instruments fracture, they mostly fracture in the apical one-third or beyond a curve of the canal because of the superelastic property. In addition, the instrument fracture immediately hinders the clinician from performing further treatment, and thus the outcome of the treatment will be compromised. Although the success rates of instrument retrieval with ultrasonics alone are very high in the range of 80 to 90 %, ultrasonic retrieval attempts are deemed to be unpredictable in terms of time and dentin sacrifice. The disadvantages of traditional instrument removal techniques are excessive removal of dentin during trephine, which may result in perforation or predispose the tooth to vertical root fracture. Hence it is essential to maintain as much tooth structure as possible to prevent root fracture and perforation. In the workshop unique techniques for instrument retrieval will be proposed and discussed to make the instrument retrieval highly predictable and minimize dentin sacrifice. The recent studies have shown that the instrument retrieval with this technique was predictable and was significantly more successful and more conservative in dentin sacrifice than the traditional techniques. The unique procedures in combination with CBCT for instrument retrieval will also be shown and discussed using contemporary concepts.

At the conclusion, participants should be able to:

  • Describe how to make an accurate diagnosis for instrument retrieval.
  • Make a predictable treatment plan for instrument retrieval.
  • Explain the concept of instrument retrieval.
