Recent studies evaluating the consequences of bone preparation led us to rethink the design of bone-cutting drills, especially those intended for implant bed preparation (IBP). The aim is to utilise highly efficient clinical protocols in combination with the preservation of bone viability at the osteotomy site. Safe and efficient clinical protocols allow for fast restorative loading protocols with predictable results.
The common drilling and tapping procedures for the conformation of the implant bed can impact the surrounding bone viability. The main purposes of drilling are to provide fixation for the implant in the apical portion and/or fixation to the lateral walls of the surrounding bone. This mechanical fixation delivers short-term primary stability.
Primary stability after implant placement can be measured with a variety of devices today, which helps the clinician to take an educated decision which treatment might be possible or best in this specific scenario. What we cannot evaluate today is the transient and long-term effect of the implant bed preparation: Depending on the drilling technique, drilling materials, drill bit geometry or bone characteristics, a greater or lesser degree of thermal and mechanical injury can occur.
Temperature rises during the bone drilling procedure can easily reach threshold temperature, above which necrosis of human bone will take place. Any critical thermal damage will result in increased bone remodelling and an extended healing period that is delaying the osseointegration process. Creating a safe IBP with healthy bone cells surrounding the implant can certainly be a key ingredient for implant success and the subsequent restorative approach.
Various clinical approaches to implant site preparation and the related thermal damage including the clinical consequences will be illuminated in this lecture:
Dr. Marcus Abboud graduated from the University of Bonn (Germany) in 1996 and started his Prosthodontic training at the same University in 1997. In 2000 he received his PhD in dentistry/Prosthodontics. From 2001 – 2003 he worked in the Department of Dental Research (Material Science) at the University of Bonn before joining the Oral Surgery Certificate Program at the same University in 2003. He successfully completed the program in 2007 and worked there as an Assistant Professor and PI for Interdisciplinary Clinical Studies until September 2010. Dr. Abboud received his Expert Certification in CBCT Technology and Diagnostics in 2010 from the Dental Medical Association Nordrhein.
Dr. Abboud was the Founding Chair of the Department of Prosthodontics and Digital Technology at Stony Brook University School of Dental Medicine (SDM) in New York from 2011-2016. During this tenure at SDM he established 3 specialty programs (Prosthodontics, Oral and Maxillofacial Prosthodontics and Oral and Maxillofacial Radiology) and a productive research and education operation. In addition, he was responsible for the Division of Endodontics and he was the Director of Continuing Education at SDM.
From July 2016 to September 2019 he was Full Professor and Associate Dean for Digital Dentistry at the University of Kentucky College of Dentistry. During his tenure he modernized the UK College of Dentistry pre- and postdoctoral education programs, improved the clinical efficiency and increased clinical revenue, patient visits and student applications due to the integration of digital dentistry and implantology in all areas of the College of Dentistry.
Since September 2019 he is working as the CEO of Loocid LLC, a medical & dental innovation company.
Dr. Abboud has authored over 50 publications, research articles and book chapters. He has performed over 250 national and international lectures on CAD/CAM technology, digital dentistry, implantology, bone grafting, guided surgery and CBCT/CT diagnostic imaging and has been involved in research for over 18 years. He holds multiple patents, being used in various countries, which provide new solutions for dentistry.
