Digitally Designed and Milled Verification Jigs Generated from Photogrammetry Data Acquisition: A Clinical Report

Area of Science:

• Dental Implantology
• Digital Dentistry
• Prosthodontics

Background:

• Conventional verification jigs are technique-sensitive and labor-intensive.
• Bridging analog and digital workflows is crucial for full-arch implant rehabilitation.
• Accurate verification of implant positioning is essential for definitive prosthesis fabrication.

Purpose of the Study:

• To present a proof-of-concept for CAD/CAM fabrication of milled verification jigs.
• To introduce a digital method for intraoral verification of digitally acquired data.
• To simplify the process of full-arch implant rehabilitation.

Main Methods:

• Photogrammetry was used for intraoral data acquisition.
• A CAD/CAM milled verification jig was designed and fabricated.
• The jig was used to verify implant 3D positioning in a patient undergoing full-arch implant rehabilitation.
• A digital prosthodontic protocol was followed.

Main Results:

• The CAD/CAM milled verification jig successfully confirmed implant 3D positioning.
• The digital workflow streamlined the verification process compared to conventional methods.
• The protocol facilitated the fabrication of definitive zirconia prostheses.

Conclusions:

• CAD/CAM milled verification jigs offer a viable alternative to conventional methods.
• This digital approach enhances the accuracy and efficiency of full-arch implant rehabilitation.
• The presented protocol effectively bridges analog and digital workflows in prosthodontics.
