It involves extraction of the offending tooth, extra oral apicectomy, followed by reinsertion of the tooth into its anatomical location. The following case report presents a situation where an endodontic instrument was separated in the mesiobuccal root of the left mandibular second molar during instrumentation that could not be retrieved. The decision of intentional re-implantation was made after detailed discussion with the patient, weighing pros and cons of each available treatment option. Fortunately, a favourable outcome was observed over a span of one year and the patient is still on follow-up for evaluation of long-term prognosis.
