LABORATORY PROCEDURE: PRECISION

Cresco API™ components used in this section:
- Replica
- Process Screw
- Bridge Support (Titanium or Burnout) 

Precisioning process
The patented Cresco™ Precision Machine is used by certified dental laboratories systematically to correct the framework distortion that occurs in the casting processes. This allows Precision Laboratories to deliver frameworks with guaranteed passive fit properties.

1. Screw-retain the Bridge Support to the Replica in the master model using the Process Screw and a slot screwdriver. Place the two Magnetic Disc’s on the two holders in the Cresco™ Precision Machine.

2. Program the Cresco Precision Machine with the desired heights to cut the apical ends of the framework. Each apical end is cut to the desired transversal plane, creating the space required for the corresponding Bridge Support.

3. The individual lengths of the Bridge Supports are calculated and cut automatically by the Cresco™ Precision Machine to fill the created spaces perfectly. During the process, corrections have also been made to compensate for the casting distortions. The Cresco Precision Machine is working with a calculating value of 0.001 mm, ensuring optimal result.

4. The end result is two transversal planes fitting each other precisely, thus creating the optimal situation for a laser weld connection.

5. Laser weld the cut Bridge Supports to their corresponding apical ends of the framework in accordance with the laser welding protocol.

Note: Remove all plaster from the precisioned parts before laser welding.

The precisioned, ground and finalized framework is sent back to the Method Laboratory.
