Area of Science:

Dentistry
Prosthodontics
Digital Dentistry

Background:

Immediate loading protocols are gaining popularity to shorten treatment durations.
Digital workflows offer advantages in speed, accuracy, and aesthetics for dental restorations.

Purpose of the Study:

To describe a fully digital workflow for fabricating immediate fixed complete dentures (FCDs) using a dual scan impression technique.
To evaluate this workflow for both zygomatic and standard implants in a patient with a severely atrophic maxilla.

Main Methods:

A dual scan impression technique involving stereophotogrammetry and intraoral scanning (IOS) was employed.
Surgical placement of zygomatic and standard implants, followed by digital scanning to create standard tessellation (STL) files.
Virtual model alignment and milling of provisional and definitive FCDs.

Main Results:

The dual scan technique resulted in a precise fit for both provisional and definitive FCDs.
The digital workflow significantly reduced scanning and fabrication times.
Improved satisfaction was reported by both the clinician and the patient.

Conclusions:

The described fully digital workflow using a dual scan technique is an effective and reliable method for fabricating immediate and definitive screw-retained FCDs.
This approach offers a viable alternative for managing complex cases requiring zygomatic and standard implants.
The digital workflow enhances efficiency and patient outcomes in implant dentistry.
