A recent international case study led by Dr. Revilla-Leon aimed to examine the accuracy of modern photogrammetry (PG) systems in recording implant positions. The study involved four extraoral systems:
- PIC from PIC Sysytem company
- ICam4D from Imetric
- Grammee from BlueSkyBio
- OxoFit from Oxo company
Additionally, researchers included one intraoral device – Aoralscan Elite from Shining 3D.
Scientists created five test groups, placing special optical markets on the implant abutment analogs and then providing 30 scans. Researchers obtained Euclidean linear and angular measurements to compare them with the experimental scans' characteristics and then used ANOVA and the Turkey test to examine the data trueness degree and the Levene test to analyze the precision level.
As it turned out, scans obtained with PIC and Icam4D have the highest linear trueness among other tools. Additionally, PIC demonstrated the best precision indicators.
Thus, research revealed that PIC Legacy – a PG system released 15 years ago and removed from the market in 2022 – provides the best results with minimal discrepancies from 0.17 to 0.34 degrees. According to PIC Dental media, these results may suggest that newer generations of PIC System's tools may provide even higher accuracy, as they are equipped with cutting-edge technologies such as Micron Vision camera modules.
