Summary
This study introduces a digital dental technique for immediate complete dentures using an intraoral scanner and CAD software. It enables precise registration of functional borders and transforms initial scans into definitive digital records.
Area of Science:
- Digital dentistry
- Prosthodontics
- Oral scanning technologies
Background:
- Traditional methods for registering functional borders of immediate complete dentures can be time-consuming and prone to inaccuracies.
- The integration of digital technologies offers potential improvements in efficiency and precision for denture fabrication.
Purpose of the Study:
- To describe a novel digital dental technique for registering the functional borders of immediate complete dentures.
- To illustrate the process of virtually matching recorded data to convert initial intraoral scans into definitive digital scans.
Main Methods:
- Utilizing an intraoral scanner for capturing patient anatomy.
- Employing dental computer-aided design (CAD) software for data processing and virtual manipulation.
- Incorporating a peripheral custom tray to aid in functional border registration.
Main Results:
- Successful registration of functional borders for immediate complete dentures using a digital workflow.
- Demonstration of virtual matching capabilities to refine initial intraoral scans into definitive digital models.
- The technique facilitates a streamlined digital process from impression to definitive digital scan.
Conclusions:
- The described digital technique offers a viable and potentially more accurate method for registering functional borders in immediate complete denture fabrication.
- This approach leverages current digital dental technologies to enhance the prosthodontic workflow.
- Further clinical validation may confirm the benefits of this digital registration technique.
