NextDent Tray is a biocompatible Class I material designed to print individual impression trays. The material distinguishes itself through high printing speed and accuracy. NextDent Tray resin enables technicians to make even the most complex trays in a matter of minutes.
The printed trays are rigid and suitable for all types of impression material, making high-quality, high-precision impressions possible.
In order to achieve good accuracy with Tray it is important to follow the part setup instructions below for orientation and supports. Some other key tips are as follows:
- Ensure flatter upfacing surfaces are well supported.
- When Tray sits for a few hours, a thin hazy film form on the surface of the membrane. While stirring, use the Resin Mixer to gently remove the film from the membrane.
CAUTION: Do NOT press down on the film when stirring.
- Verify proper cleaning method. Insure cleaning solvents are not saturated and parts are allowed to dry before post cure.
Most Tray models have a feature on the end used as a handle. Orient part with at the handle normal to the XY-plane. In addition, the supports should not be on the fitted surface. Thus, the part may need to be tilted in a direction to prevent supports being added to this surface.
Figure 1. Right side view of properly oriented tray part.
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. The supports should also properly cover bottom area of tray or from gum area.
Figure 2. Bottom view of part on left needs supports manually added to part using Modify tab tools. Right side view is a properly supported tray part.
Figure 3. Isotropic view of part shows no supports are on the fitted surface of the part.
Tray parts may have text and/or numbers engraved onto the handle of the part. The support nodes should be removed from this area using the tools on the Modify tab.
Figure 4. Text on handle of part has supports within the engraved area. Image on the right has the supports properly removed.
