Area of Science:

  • Dentistry
  • Digital Dentistry
  • Prosthodontics

Background:

  • Intraoral scanners are increasingly popular for dental impressions.
  • Traditional custom tray techniques remain valuable, especially for multiple abutment teeth.
  • Manual custom tray fabrication involves complex laboratory procedures.

Purpose of the Study:

  • To present a digital workflow for designing custom trays.
  • To utilize open-source software for custom tray fabrication.
  • To offer an alternative to traditional and proprietary digital methods.

Main Methods:

  • A digital workflow was developed for custom tray design.
  • Open-source dental software was employed in the workflow.
  • The process focuses on creating a definitive impression tool.

Main Results:

  • A custom tray can be designed using readily available, open-source software.
  • This digital approach bypasses the need for manual laboratory fabrication.
  • The workflow addresses the cost barrier associated with additional software modules.

Conclusions:

  • Open-source software provides a viable solution for digital custom tray design.
  • This workflow enhances accessibility and potentially reduces costs in dental prosthodontics.
  • Digital custom tray fabrication is achievable without expensive proprietary software.
