- Works with all impression materials.
- Wax bonds directly — edge shaping without pretreatment.
- Rigid enough not to give way on removal.
A custom tray gives an even material thickness in the impression, and that is where the accuracy comes from. KeyTray does not flex when the tray is pulled off, and takes wax directly when the borders are to be shaped.
