Using Dental LT Comfort Resin: A Step-by-Step Guide

Follow this guide to successfully integrate Dental LT Comfort Resin into your workflow for producing high-quality, biocompatible splints.

1. Design

Using your preferred dental CAD software, design the splint or guard. For optimal results, ensure the design has a minimum thickness of 2.0 mm on the occlusal surface and 1.5 mm on the buccal and lingual walls. Once complete, export the design as an STL or OBJ file.

2. Print

Import the file into PreForm software. Select "Dental LT Comfort" as the material and a layer height of 100 microns. Orient the part with the occlusal surface angled between 10–30 degrees relative to the build platform for the best balance of accuracy and print speed. Ensure a dedicated, clean resin tank and build platform are used to maintain biocompatibility.

3. Wash

Place the printed parts in a Form Wash filled with isopropyl alcohol (IPA, ≥96%) and wash for 5 minutes. This removes any uncured resin from the surface. Do not exceed the recommended wash time as it can affect the part's dimensional accuracy.

4. Dry

After washing, remove the parts and allow them to air dry completely for at least 30 minutes. You can use compressed air to speed up the process. The parts must be fully dry and free of any tackiness before post-curing.

5. Post-Cure

Place the clean, dry parts in a Form Cure. Post-cure at 60 °C for 60 minutes. This step is mandatory to achieve the material's full mechanical properties and ensure its biocompatibility for patient safety.

6. Finishing and Polishing

First, remove the support structures using a cutting disc. To achieve high optical transparency, polish the appliance using a two-step process. Start with a rag wheel and fine pumice to pre-polish the surface. Then, use a dry rag wheel with a polishing compound to achieve a final, crystal-clear finish.
