Summary
This study introduces a novel digital workflow for fabricating custom trays for maxillofacial prostheses. This technique accurately replicates denture morphology using intraoral scanning, CAD software, and 3D printing for improved prosthetic outcomes.
Area of Science:
- Biomedical Engineering
- Dental Prosthetics
- Digital Dentistry
Background:
- Maxillofacial prostheses require precise replication of denture morphology for optimal function and aesthetics.
- Traditional methods for custom tray fabrication can be time-consuming and may not accurately capture complex denture shapes.
Purpose of the Study:
- To present a new fabrication workflow for a three-dimensional (3D) printed custom tray.
- To duplicate the morphology of a treatment denture for maxillofacial prostheses using digital technology.
Main Methods:
- Utilized an intraoral scanner to capture the oral cavity's morphology.
- Employed computer-aided design (CAD) software for data adjustment and a 3D printer for custom tray fabrication.
- Integrated treatment denture morphology into the definitive denture through a silicon impression of the cameo surface.
Main Results:
- The 3D printed custom tray accurately fitted the patient's mouth.
- Closed tray impressions were successfully made for implant-supported locator attachments.
- The morphology of the treatment denture was accurately transferred to the definitive implant partial denture.
Conclusions:
- This digital technique offers a practical and accurate approach for fabricating custom trays and definitive dentures.
- Leveraging existing digital technology enables precise replication of denture morphology, beneficial for complex maxillofacial defects.
