Stackable surgical guides represent the state of the art in guided implant surgery. Unlike single guides, stackable systems use multiple guide layers, each dedicated to a specific surgical step, enabling progressive precision throughout the procedure.
How Stackable Guides Work
Layer 1 (Base Guide): Seats on teeth or mucosa, establishing the primary reference plane. This guide remains in place throughout surgery.
Layer 2 (Pilot Guide): Fits onto the base guide, directing the pilot drill to the exact planned entry point and angulation.
Layer 3 (Sequential Guide): Guides progressively larger drills, each increasing osteotomy diameter while maintaining axis control.
Layer 4 (Final Guide): Directs the final drill or implant placement, ensuring the implant seats exactly as planned.
Advantages Over Single Guides
- Each drill size has a dedicated sleeve, eliminating sleeve wear issues
- Progressive control reduces angular deviation at each step
- Better irrigation access due to layered design
- Individual layers can be replaced if contamination occurs
