Photogrammetry Technique for the 3D Digital Impression of Multiple Dental Implants

2019
In the computer-aided design and manufacturing (CAD/CAM) dentistry, intra-oral scanners (IOS) are usually used to capture the teeth/implants position and adjacent soft tissues for fabrication of prostheses. However, scanning errors are associated with IOS for full arch impressions and teeth/implants with divergent alignments.
