Straight vs Angulated Multi-Units: the decision that determines where your screw channels land. In immediate full-arch workflows, you don’t “discover” screw access later – you design it at the MUA stage. This is exactly where the XGATE Standard prosthetic concept comes into play. This walkthrough shows a practical way to predict screw-channel emergence before scanning and milling a next-day provisional.
When you place straight MUAs, the screw channel follows the implant axis — easy to read, easy to plan. With angulated MUAs, the channel may shift unpredictably unless you have a clear reference for the future axis. That’s where a positioning handle becomes a planning tool, not just an insertion tool.
Key point: if you scan at the multi-unit level, you’re committing to that platform/angulation — you can adjust height later, but you can’t “convert” a 30° workflow into straight or 17° without re-impressing.
