LABORATORY PROCEDURE: PRECISION
Cresco API™ components used in this section:
- Replica
- Process Screw
The page guides you through the Precision Laboratory and Prosthetic procedures but retains the main focus on the Method Laboratory handling procedures. Therefore a more detailed Precision Laboratory procedure is needed for the Precision Laboratories.

|
1. Screw-retain the framework to the master model using at least two Process Screws and a slot screwdriver. Tighten the framework using light finger force.
|
|
|
2. Apply sticky wax to the interface between the ends of the Replicas and the apical ends of the framework to secure the position between the framework and the Replica in the master model.
|
|
|
3. Remove the retaining Process Screws carefully, leaving the sticky wax intact.
Note: The Process Screws must be completely removed.
|
|
|
4. Mount the master model with the sticky wax-retained framework onto a Magnetic Disc using plaster. Place the unit in the top holder of the Fixator. Build up plaster on an additional Magnetic Disc and place it on the bottom holder of the Fixator.
|
|
|
5. Lower the framework unit to a fixed vertical level by closing the Fixator and thereby dipping the framework into the plaster material. After the material has set, remove the sticky wax.
|
|
|
6. Separate the two Magnetic Discs with the framework now embedded in the hardened plaster material of the opposing Magnetic Disc. The Fixator preserves the vertical and horizontal relationship between the Replicas in the master model and the framework. If necessary, remove plaster material to expose at least 3 mm of the apical ends of the framework.
