QuadroJig: A Reverse-Engineering Analog Protocol for Prosthetic- Periodontal Co-Acquisition in Full-Arch Implant
Summary
The QuadroJig protocol offers a structured workflow for full-arch implant rehabilitation, improving prosthetic and biologic information transfer during delayed loading cases. This method enhances precision in implant placement and soft tissue management.
Area of Science:
- Dental Implantology
- Prosthodontics
- Periodontology
Background:
- Digital workflows are common in full-arch implant rehabilitation.
- Delayed-loading cases need structured methods for transferring information between removable and fixed prostheses.
Purpose of the Study:
- Introduce the QuadroJig protocol for analog-driven, transdisciplinary full-arch implant rehabilitation.
- Enable simultaneous acquisition of critical prosthetic and biologic data.
Main Methods:
- Utilize a stabilized intraoral construct from a flangeless denture duplicate.
- Employ vertical bone sounding for periosteal mapping and execution.
- Reverse-engineer the prosthetic tissue junction for prototype fabrication.
Main Results:
- Simultaneous acquisition of implant position, occlusion, esthetics, and soft tissue dimensions.
- Facilitates prosthetic-periodontal co-acquisition and execution.
- Supports fabrication of prototype prostheses coordinated with peri-implant anatomy.
Conclusions:
- The QuadroJig protocol provides a practical approach to delayed full-arch rehabilitation.
- It is particularly beneficial in digitally underserved clinical settings.
- The workflow integrates prosthetic design with peri-implant anatomy for improved outcomes.
