Extra-oral photogrammetry (EPG) is emerging as a reliable alternative to intra-oral scanning for full-arch implant impressions. While IOS performs well in short spans, its accuracy decreases in edentulous arches due to stitching errors and lack of reference points.

EPG overcomes these limitations by capturing implant positions through multi-angle imaging, delivering highly precise 3D data without the need for stitching. However, as it does not record soft tissue, it must be combined with an intra-oral scan to enable complete prosthetic design.

In bone augmentation procedures for implant treatment, proper evaluation of bone defect morphology and appropriate barrier membrane selection significantly influence treatment predictability. Learn more about bone defect morphology and appropriate barrier membrane selection in this article.
