Image-guided photogrammetry accuracy: In vitro evaluation of an implant-supported complete arch digital scanning technology

Image-guided photogrammetry was feasible for implant-supported complete arch digital scanning with linear and 3D deviations lower than those of conventional SPG. Linear deviations were close to 0 µm and angular deviations about 0.4 degrees, with the 4-implant casts being more accurate. Implant position did not affect accuracy with the exception of anterior implants that showed higher angular deviations in the 6-implant casts. Even though actual patient casts were investigated, allowing the IGP outcomes to be generalized with caution, trials are needed to validate its clinical performance.
