# Preserve Before You Replace: Modern Endodontic Microsurgery for Natural Tooth Preservation ![endodontic tools](/sites/g/files/omnuum6001/files/styles/hwp_5_4__480x385/public/2026-07/endo_equipment.jpg?itok=Y4JCAK5i) #### calendar\_today Date and Time **November 19, 2026** 07:00PM - 08:00PM EST #### pin\_drop Location **Zoom** [ Register arrow\_circle\_right ](https://cvent.me/9EzzkV) ## About this webinar As implant dentistry continues to expand treatment possibilities, preserving the natural dentition remains a cornerstone of comprehensive patient care. Modern endodontic microsurgery has transformed what was once considered a procedure of last resort into a highly predictable, precision-driven treatment that can extend the lifespan of natural teeth. In this one-hour webinar, [**Dr. Allen Ali Nasseh**](/people/allen-ali-nasseh "Allen Ali Nasseh") will explore the evolution of endodontic surgery from traditional apicoectomy techniques to contemporary microsurgical approaches that incorporate magnification, enhanced illumination, advanced biomaterials, and minimally invasive protocols. Through real-world clinical cases and evidence-based treatment concepts, participants will learn how endodontic microsurgery can provide patients with an opportunity to retain strategic teeth that may not be suitable candidates for nonsurgical retreatment alone. Designed for clinicians seeking practical guidance in treatment planning, this session will examine case selection, surgical principles, biologic considerations, and restorative decision-making that support long-term tooth preservation. Participants will gain practical insights into when microsurgery may be the preferred alternative to extraction and implant replacement. This webinar will strengthen your understanding of modern microsurgical techniques and reinforce the value of preserving natural dentition whenever possible. --- *This webinar is part of the monthly* [**HSDM** **Specialty Lecture Series**](#series)*, monthly one-hour live webinars designed to fit your busy schedule.
