Navigating Full Arch Challenges: A Talk with Dr. Sean Lan: Part 3

What if your membrane actually stayed put and your grafts healed the way you planned? We sat down with Dr. Sean Lan to map a practical path from soft tissue basics to hard tissue confidence, focusing on the decisions that make full-arch treatment predictable rather than precarious.

We start where results begin: donor thickness and visibility. Sean explains why 3–4 mm palatal tissue unlocks pedicled options, when a free CTG is the better bet, and how loupes transform half‑millimeter judgment calls. On maxillary implants, we compare buccal soft tissue strategies—pedicled wrap to bone vs tack‑on CTG—and share when a large palatal flap after reduction can be repurposed for added volume. Stability threads through everything: quick transosseous anchor points, when to suture to abutments, and how to get tension‑free closure with thoughtful flap advancement.

Then we shift to bone. Think “wet sand in a cup” for within‑contour grafts, and why going outside the contour changes physics, risk, and membrane demands. We unpack buckle veneer grafts, sticky bone myths, autogenous techniques like split bone blocks, and realistic membrane choices guided by PASS principles. If you’ve ever fought a floating membrane, you’ll get step‑by‑step tactics: periosteal slings, apical tacking sutures, fixation screws, double‑membrane shortcuts, and using implants or transosseous holes as smart anchor points. Sean also shares a practical cortical plate save—his “poor man’s plate”—to avoid over‑reduction and set up a site that later needs only soft tissue finishing.

Mandibles get honest airtime: fewer escape routes, more muscle pull, higher stakes. We talk training that actually helps—Pink Bible, Zucchelli’s volumes, selective live courses—and how to build reps ethically. Zygomatic implants enter as a necessary but rare tool, best learned with supervision and careful indications. We close on subperiosteals in the most atrophic jaws, urging product decisions to follow biology and evidence, not marketing. Sometimes the most patient‑centered answer is a bar overdenture instead of “fixed at all costs.”
