NextDent Try-In

NextDent Try-In is a biocompatible Class I material suitable for printing Try-In devices, a baseplate combined with the individual designed tooth setup, to check bite registration and occlusion.

Accuracy Tips

In order to achieve good accuracy with Try-In it is important to follow the part setup instructions below for orientation and supports. Some other key tips are as follows:

  1. Angle the model-fitting surface 30 degrees from the build area as shown in the Orientation section below.
  2. Verify proper cleaning method. Insure cleaning solvents are not saturated and parts are allowed to dry before post cure.

Orientation – Full Arches

Orient part with the front palate facing towards the grid on 3DSprint™. Use Transform functions to orient part such that the fitted surface does not have down facing surfaces.

Add Supports – Full Arches

Add supports to the part using the Create Supports function under the Smart Supports icon. Look at the supports and determine how they may need to be modified. The supports should not be on the fitted surface. As shown in Figure 37. These are a result of bad part orientation.

Reorient the part and check for support nodes on the fitting surface. If nodes still appear, then remove them using the Modify tools in Smart Supports window.

In addition to the fitted surface, the gun line should not have supports near the fitted edge. If support nodes appear to near the gum line, reorient the part. If nodes still appear, then remove them using the Modify tools in Smart Supports window.
