The Luckman Post Dam Technique (Digital Workflow In Exocad) | Overview of Technique

In this video, I break down the Luckman post dam technique from start to finish — and show you exactly how I apply it in a fully digital workflow using Exocad. After sharing a quick overview of this technique, I had dentists and lab technicians from all over the world reach out wanting more detail. So in this video, I go deeper. This is not a new technique — it’s been around for a long time — but when you combine it with digital design tools, it becomes incredibly powerful. Credit to Cory Glenn for opening to my eyes to this digital technique. Here’s what we cover: • How to identify key anatomical landmarks (incisive papilla, hamular notches, vibrating line) • The “inverted guitar pick” design concept for the post dam • Proper depth control (≈1 mm center, feathering to ~0.5 mm) • Why compressible tissue selection is critical (and where most people go wrong) • Step-by-step execution inside Exocad using “distance to scan data” • How to build a true peripheral seal before placing your post dam • Tips to avoid rocking, discomfort, and poor retention This is one of those techniques where small details make a massive difference in retention and patient comfort. Digital dentistry doesn’t replace fundamentals — it magnifies them. If you’re designing dentures digitally (or want to start), this is a technique worth mastering.
