DAN HOLTZCLAW: Full Arch Immediate Implant Therapy Complications - The PATZI and HESIAn Protocols


Immediately loaded full arch dental implant procedures such as All-On-X have a 20+ year history of successful performance. While most short-term studies show extremely high survival, mid to long term studies have shown trends of increasing failure rates for conventional implants in such cases. Many AOX cases have minimal bone to begin with, and these situations are exacerbated when implants fail. Remote anchorage techniques such as zygomatic and pterygoid implants can rescue failing AOX cases with applications such as the PATZi protocol. What can be done, however, when these advanced implants fail. The Holtzclaw Extrasinus Infratemporal Anchorage (HESIAn) zygomatic implant protocol is a highly advanced method which can rescue these cases. In addition to reviewing the principles of the PATZi protocol, this lecture will describe the HESIAn protocol, its indications, and provide an analysis of multiple cases with up to 3 years of follow up.
