This LIVE-demo workshop will demonstrate the importance of proper positioning of the microscope/patient/doctor for microsurgery, enabling the practitioner to do the surgery comfortably and efficiently. A complete surgery will be performed on an extracted tooth mounted in a stone model, reproducing real-life situations. The procedure will be performed under the microscope utilizing all the microsurgical instruments as well as the new generation of bioceramic putty for root end fillings. The armamentarium will be discussed in detail, allowing the audience to see each instrument's relevance for the procedure.

Evolutionary technologies have resulted in a new generation of instruments designed to access areas that traditional "round" NiTi cannot safely reach. After initial negotiation of the root canal space with a glide path file, these "virtual core" files complete the cleaning to the maximum natural diameter. The native anatomy configuration is sustained and intra-canal dentin conservation is optimized. This conservative root treatment is completed by bioceramic root filling technology that does not shrink, wash out or require excessive preparation on the coronal third of the canal space. Participants will experience the use of these instruments and learn the subtle differences between the use of these files and the traditional NiTi instruments.

This LIVE-demo course offers training in non-surgical retreatment under microscope, with new three dimensional files that allow for effective and easy gutta percha removal from the canals. The key to successful retreatment is adequate disinfection. In order to allow for irrigation and medication to be effect against the persistent intracanal infection, the previously filled gutta percha and sealer have to be efficiently removed. Along with finisher files the re-instrumented canals are cleaner both of debris and biofilm. After biomechanical instrumentation, obturation technique with bioceramic sealer and gutta percha will be demonstrated to reseal the canal hermetically. By the end of the session the participant should be able to remove gutta percha, instrument and obturate a couple teeth of various complexities in an adept structured workflow, which is repeatable, and easily transferable to their clinical practice. An iatrogenic error such a perforation can be disheartening. During this hands-on steps to repair perforations with biocermaic putty will also be discussed.
