Full-arch implant dentistry is often discussed in terms of scanner performance and “optical accuracy,” yet long-term clinical success depends just as much — if not more — on geometric control and data alignment.
This lecture explores the critical distinction between optical capture and geometric stability in All-on-X workflows. Participants will gain a clear understanding of why full-arch errors accumulate, how drift occurs, and why passive fit is fundamentally a geometry challenge rather than a purely optical one.
Key topics include:
• Why “good scans” can still produce misfit prostheses • The role of landmark geometry in cross-arch stability • Data merge reliability and cross-dataset anchoring • Central-first scanning strategies to control drift • The impact of scan body design on reproducibility • Clinical implications for passivity, occlusion and long-term success • How Scan Ladder’s design philosophy addresses geometric accuracy in real-world workflows
This session is ideal for clinicians and technicians who want to move beyond marketing claims and understand the true drivers of predictable All-on-X accuracy.
Attendees will leave with practical insights they can immediately apply to improve full-arch outcomes, reduce remakes, and achieve more reliable passive fit.
Education focus: Work smarter, not harder — by understanding the geometry behind accuracy.
