Summary
A new digital workflow integrates metal frameworks into implant overdentures using the custom disk method. This technique ensures a precise fit and accurate artificial tooth placement for enhanced patient outcomes.
Area of Science:
- Dentistry
- Biomaterials Engineering
- Digital Fabrication
Background:
- Digital workflows for complete dentures are established, but not for those with metal frameworks like implant overdentures.
- Existing methods lack standardization for fabricating complex implant-supported prosthetics.
Purpose of the Study:
- To describe a novel digital workflow for fabricating implant overdentures with metal reinforcement.
- To adapt the custom disk method for creating implant overdentures with integrated metal frameworks.
- To establish a standardized technique for metal-reinforced complete dentures.
Main Methods:
- Utilized a custom disk method with prefabricated artificial teeth embedded in resin.
- Milled both the denture base and artificial teeth simultaneously from the custom disk.
- Integrated a metal framework into the resin denture base for a 4-implant-supported overdenture.
Main Results:
- Successfully fabricated a 4-implant-supported overdenture with a metal reinforcement using the digital workflow.
- The custom disk method was effectively applied to implant overdenture fabrication with metal frameworks.
- Achieved a precise fit of the denture base and accurate positioning of artificial teeth.
Conclusions:
- The described digital workflow provides a viable method for fabricating implant overdentures with metal frameworks.
- This technique offers a standardized approach applicable to both implant overdentures and complete dentures with metal reinforcement.
- The integration of metal frameworks enhances denture stability, fit, and aesthetic outcomes.
