Keystone ProForm .020" crown and bridge material: thin, clear, rigid thermoforming sheets for vacuum-forming matrices over a model or wax-up. The clear matrix is used to fabricate chairside provisional crowns and bridges and to check reduction during preparation.
The material holds its shape once formed, lets you see the material and margins through it, and bonds to acrylic. Each 5" x 5" sheet fits standard vacuum and pressure forming machines.
