Scan and Import Models

To begin, scan the patient's teeth using an intraoral scanner and generate a digital model in .STL format. Import the .STL file into D3 Splint software. It is important to clean up the model by removing any soft tissue or unwanted elements that may interfere with the night guard design process. You can use a free software called Meshmixer to clean the models.

Articulate Models

Once the models are prepared, mount them on a virtual articulator in D3 Splint. Adjust the articulator pin to create room for the splint (usually 2mm thick is a good default) to simulate the patient’s bite and jaw movements. This step ensures that the night guard fits correctly and provides the necessary occlusal contact for comfort and effectiveness.

Design the Night Guard

Utilize D3 Splint’s tools to outline the perimeter of the night guard, defining the areas it will cover. Choose from design options like a flat plane or anterior ramp and adjust the thickness to meet the patient’s needs. Refine the design by smoothing out rough edges and sculpting thin areas.

Add a Print Support and Label

To facilitate printing, your 3d printing software can add supports, but D3 splint also has options to add small raft platforms or supports that connect to the anterior the guard only. This supports proper positioning during the 3D printing process. Include a label for easy identification, such as the patient’s initials or a practice-specific code.

Export and Print

Export the final design as an STL file from D3 Splint and import it into a 3D printing software and print!

Post-Processing

After printing, remove the night guard from the printer and break off the base or raft. Polish the night guard using a polishing paste to ensure it is smooth, comfortable, and ready for patient use.

Key Points

  • Accurate Scanning and Model Preparation: Ensuring clean and precise digital models is essential for successful night guard design.
  • Articulation: Proper articulation settings ensure the night guard fits well and provides effective occlusal protection.
  • Design Refinement: Smoothing out rough areas and adjusting undercuts ensures patient comfort.
  • Post-Processing: Polishing is vital for creating a finished product that is comfortable and effective.

Additional Considerations

  • Resin Selection: Use biocompatible resin suitable for night guards to ensure patient safety.
  • Customizations: Add bite ramps or grooves to address specific patient needs.
  • Patient Follow-Up: Schedule a follow-up appointment to ensure proper fit and function, making adjustments as necessary.

Overall Conclusion

Designing and 3D printing night guards using D3 Splint and 3d printing in-office is an efficient and effective workflow for dental practices. This process allows for the creation of high-quality, custom-fit night guards, improving patient outcomes while streamlining the production process. With the right tools and training, this technology can become a valuable asset in any dental practice.
