Predictable Clinical Full Arch Workflows with Advanced Tips, Troubleshooting and Integration
Featuring Dr. Ahmad Al-Hassiny, this webinar discusses the evolution of digital workflows in full-arch implant dentistry. He compares horizontal scan body systems to traditional photogrammetry, presenting data that demonstrates their accuracy. The lecture emphasizes the importance of operator skill, proper tissue management, and choosing the right scanner for immediate post-op cases to achieve a passive fit.
This course examines in detail the predictability and accuracy of digital workflows in All-on-X implant dentistry. Dr. Ahmad begins by sharing his background and critiquing the historical reliance on photogrammetry, arguing that while it was once considered the gold standard, it is often unnecessary bulk and expense compared to modern intraoral scanning solutions.
The core of the lecture deeps dive into horizontal scan body systems. Dr. Ahmad explains the two critical steps in these workflows: digital alignment and the transfer from horizontal to vertical abutment data. He presents comparative data from his own research, highlighting that while photogrammetry and high-end scanners achieve accuracies around 20-30 microns, horizontal scan bodies (such as DirectIP) can achieve even better results, approximately 18-25 microns, which is sufficient for a passive fit.
The speaker provides an extensive review of various commercial systems, analyzing their pros, cons, and pricing structures. He strongly advocates for open, streamlined workflows integrated directly into the scanner software to eliminate extra steps. Furthermore, the lecture covers practical clinical tips, including the necessity of retracting soft tissues for accurate scanning, troubleshooting common issues like overlapping scan bodies, and the importance of verifying MUA seating with X-rays to prevent costly remakes.
