SP-37 - The Research and Application of Dynamic Navigation Technology in Endodontic Microsurgery

Presentation Description/Abstract: In recent years, dynamic navigation (DN) technology has been increasingly applied in the field of endodontics. This presentation presents the research and application of a novel approach of DN used in Endodontic Microsurgery (EMS), which can be divided into two parts. In the first part of in vitro study, we explore the accuracy and efficiency of DN-assisted EMS in a surgical simulation model, with the comparison of different guided methods[1], registration methods, and field of view and voxel size of CBCT. In the second part of in vivo study[2], we investigated the accuracy[3] and prognosis outcomes of DN-assisted EMS, with an analysis of potential prognostic factors. Based on our results, DN technology could improve the accuracy and efficiency for guided osteotomy and root-end resection and achieve a favorable prognosis in EMS. In conclusion, DN-aided-EMS could be considered an effective and reliable treatment strategy.
