This study presents a novel dental implant workflow combining extraoral photogrammetry and reverse scanning. This method efficiently fabricates complete-arch implant-supported prostheses for both upper and lower jaws.
Area of Science:
- Dental Technology
- Prosthodontics
- Digital Dentistry
Background:
- Fabricating implant-supported restorations requires precise digital scanning.
- Existing implant scanning workflows can be complex and technique-dependent.
- Understanding registration procedures is crucial for integrating scan data.
Purpose of the Study:
- To describe an efficient implant workflow for fabricating complete-arch implant-supported prostheses.
- To detail the combination of extraoral photogrammetry and reverse scanning methods.
- To highlight the importance of understanding scanning steps and reference landmarks.
Main Methods:
- Utilized extraoral photogrammetry for data acquisition.
- Employed the reverse scanning method for implant position capture.
- Combined these techniques for maxillary and mandibular complete-arch prostheses fabrication.
Main Results:
- Successfully fabricated complete-arch implant-supported prostheses using the combined technique.
- Demonstrated an efficient workflow for capturing necessary scan data.
- Provided clear steps and reference landmarks for technology implementation.
Conclusions:
- The combined extraoral photogrammetry and reverse scanning workflow is effective for complete-arch implant restorations.
- Understanding specific scanning techniques and landmarks enhances workflow efficiency and success.
- This approach offers a streamlined solution for dental professionals in implant prosthodontics.
