In this episode of\u00a0<\/span><i><span data-contrast=\"auto\">Endo Voices<\/span><\/i><span data-contrast=\"auto\">, Dr. Marcus Johnson joins internationally recognized clinician, researcher, and educator Dr. Yoshi Terauchi for a highly technical yet practical exploration of the science and strategy behind predictable instrument retrieval. From cyclic and torsional fatigue to canal curvature, fragment location, and CBCT assessment, Dr. Terauchi explains why successful retrieval begins with diagnosis, visualization, and disciplined treatment planning.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Dr. Terauchi shares the principles behind his systematic approach to retrieval, including strategic dentin removal, ultrasonic technique, bypassing, and the clinical application of the Yoshi Loop. The conversation highlights the delicate balance between persistence and preservation: when does continued retrieval become more damaging than the fragment itself? Along the way, Drs. Johnson and Terauchi discuss secondary fracture, apical displacement,\u00a0pericervical\u00a0dentin preservation, tactile sensation, and those difficult cases in which the separated instrument lies beyond the curvature.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true}\">\u00a0<\/span><\/p>\n<p><i><span data-contrast=\"auto\">Endo Voices is generously sponsored by\u202f<\/span><\/i><a href=\"https:\/\/www.endodonticpracticepartners.com\/\"><i><span data-contrast=\"none\">Endodontic Practice Partners<\/span><\/i><\/a><i><span data-contrast=\"auto\">.<\/span><\/i><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true}\">\u00a0<\/span><\/p>\n","protected":false},"featured_media":31122,"comment_status":"closed","ping_status":"closed","template":"","feature":[],"podcast-topic":[280,284],"class_list":["post-31121","podcast","type-podcast","status-publish","has-post-thumbnail","hentry","podcast-topic-problem-solving-in-endodontics","podcast-topic-saving-teeth"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Mastering Separated Instrument Retrieval with Dr. Yoshi Terauchi \u2013 Ep. 86 - American Association of Endodontists<\/title>\n<meta name=\"description\" content=\"Endo Voices Podcast is brought to you by the American Association of Endodontists.
