Complete Digital Restoration: Implant-Supported Prosthesis Using Rapid Prototyping and a Model-Free Approach

Area of Science:

• Dentistry
• Digital Dentistry
• Prosthodontics

Background:

• Periodontally compromised dentition necessitates advanced restorative solutions.
• Traditional workflows for full-arch implant rehabilitation can be time-consuming and involve multiple appointments.

Purpose of the Study:

• To present a completely digital workflow for fabricating provisional restorations in full-arch dental implant rehabilitation.
• To evaluate the efficiency and patient comfort of a cast-free approach using digital technologies.

Main Methods:

• Utilized digital intraoral scanning for data acquisition.
• Employed rapid prototyping techniques, including milling and 3D printing, for provisional restorations.
• Implemented a staged approach with preplanned provisional restorations for a six-implant supported mandibular prosthesis.

Main Results:

• The digital workflow facilitated a cast-free fabrication process.
• Staged provisional restorations allowed for a smooth transition to final implant rehabilitation.
• The approach demonstrated increased patient comfort and time efficiency in clinical procedures.

Conclusions:

• A completely digital workflow is feasible for full-arch implant restorations.
• Digital preplanning and fabrication of provisional restorations enhance clinical efficiency and patient experience.
• This cast-free method offers a modern alternative for dental implant rehabilitation.
