1. „Box in" the impression on the tray carrier for pin paralleling.
|
|
|
|
2. Place tray carrier with impression onto the slider with solid ZEISER® base plate underneath.
|
|
3. Survey the required pin position and drill the pin holes.
|
|
|
|
4. Push table down gently to defi nite stop position. Drill two holes per segment.
|
|
5. Insert tapered pins into drilled holes and press down according to friction required.
|
|
|
|
6. Pour up the impression with die stone or BLUE-STAR.
|
|
7. Load ZEISER®-base plate with stone or BLUE-STAR around pins. Invert plate; seat onto the impression.
|
 |
 |
8. After approx. 20 minutes (stone) or 8 hrs (BLUESTAR) remove the impression from the tray carrier and separate the „pour up" from the base plate. Simply tap the base plate with a small hammer, until the arch lifts off.
|
| 9. Take the arch right off the base plate.
|
 |
 |
10. Trim the arch, clean, blow dry and reposition back onto base plate.
|
|
11. A visible gap between tooth arch and base plate will show the actual stone expansion. Now section the model: The linear expansion is thus eliminated and the segments will drop back flush onto the base plate. The expansion error is now corrected.
|
 |
 |
12. The ZEISER® master model, a dimensionally stable and perfectly accurate reproduction of the actual situation in the mouth. „There will be no visible dimensional change across the arch using BLUE-STAR epoxy resin."
