_On16April2010,thefirstlivedemonstrationof a cutting-edge endodontic surgical procedure was presented at the American Association of Endodon- tists annual scientific session in San Diego. Performed by Dr L. Stephen Buchanan, the experi- mental procedure—CT-guided endodontic Surgery (GES)—used SimPlant surgical treatment planning software(Materialise)toplotanidealpathtothedis- eased mesio-buccal (MB) root and bone of an upper firstmolar.Thiswasfollowedbythedigitalfabrication of a SimPlant drill guide to transfer the treatment planned in computer space to the patient’s jaw. While this drilled guide software has been used successfully for many years in implant dentistry, it hadnotbeenpreviouslyusedforendodonticsurgery. Dr Buchanan said he was introduced to the GES concept when he trained for implant surgery. His friend,thelateDrDavidRosenberg,towhomheded- icatedthisprocedure,taughthimthatdrillguidescan greatly improve surgical speed and accuracy during implantplacement.WhenagraduatestudentatUCLA asked whether CT-generated drill guides could work forendodonticsurgery,hesaidthathiswholeconcept of endodontic surgery changed. Surprisingly, upon conducting a literature search, Buchanan found out thisconceptwasfirstbroughtintothepublicdomain in 2007.1 Fortheseveralhundredendodontistswhowatched this live demonstration, it was clear this was not yet a more efficient procedure. The potential, however, was evident. 44 I I meetings _ AAE 2010 roots2_2010 AAE hosts first live CT- guided endodontic surgery Author_ Sierra Rendon, USA
