This study presents a digital workflow for creating implant overdentures using unsplinted attachment systems. This method enhances patient outcomes through improved cleansability and cost-effectiveness.
Area of Science:
- Dentistry
- Prosthodontics
- Digital Dentistry
Background:
- Unsplinted attachment systems for implant overdentures offer advantages like cost-effectiveness and easier cleaning.
- Edentulous patients benefit from improved manual dexterity with these systems.
Observation:
- A digital workflow for fabricating a maxillary implant overdenture using conometric-style attachments (Atlantis® Conus) opposing standard attachments (LOCATOR®) is detailed.
- The workflow incorporates a facially driven approach, digital scanning of master casts with wax rims, and virtual tooth set-up for predictable esthetics.
Findings:
- The described procedure offers a predictable and accurate technique for digital fabrication of implant overdentures.
- The workflow includes virtual teeth set-up, 3D-printed trial dentures, milled definitive prostheses, and intraoral pick-up for both attachment systems.
Implications:
- This digital workflow provides a streamlined and accurate method for fabricating implant overdentures with unsplinted attachments.
- The technique enhances patient satisfaction by improving esthetics, function, and hygiene.
