An instrument fracture is very frustrating. Instrument retrieval is even more frustrating and considered the most challenging in endodontics. 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 lecture unique techniques for instrument retrieval will be proposed and discussed to make the instrument retrieval highly predictable and minimize dentin sacrifice. The accurate diagnosis and treatment planning in combination with CBCT for instrument retrieval will also be shown and discussed using contemporary concepts.
