The Dual Laminate Guard combines a hard acrylic outer shell (for durability) with a soft inner liner (for comfort and retention). It offers the best of both worlds — protection from severe bruxism with the comfort of a soft liner.
Components
• Outer Layer — Hard PMMA, 1.5-2.0mm • Inner Liner — Soft EVA or silicone, 1.0mm • Full-Arch Coverage • Dual-Layer Bond — Chemical and mechanical bond
How It Works
The soft inner liner conforms to tooth surfaces, providing excellent retention and comfort. The hard outer layer resists wear from heavy grinding, protecting both the teeth and the inner liner from perforation.
Digital Workflow
1. Intraoral scan 2. 3D-print model 3. Thermoform inner soft liner (1.0mm) onto model 4. Wax hard outer layer over the liner 5. Flask and process outer PMMA 6. Bond layers during processing 7. Trim and polish 8. QC: Layer bond, thickness, comfort
Manufacturing Standard
• Outer: Heat-cured PMMA, 1.5-2.0mm • Inner: EVA/silicone, 1.0mm, Shore A 60-80 • Bond: Chemical + mechanical, must not delaminate • QC: Layer thickness measurement, delamination test, fit
