This research aims to develop a photogrammetric technique for precise measurements of dental implants and their fit with superstructures.
Developed a camera setup for photogrammetric measurement of dental implants in 3D.
Calibration achieved a measurement accuracy of 0.005 mm using a high-precision analytical plotter.
Measured angular orientation of implants with a precision of 0.01 radians.
Achieved measuring accuracy of 0.02 mm for well-defined clinical components.
Estimation of the center point of implants with precision of 0.05 mm.
Measurements indicated a peripheral gap error of about 0.03 mm, significantly lower than the clinical fit gaps observed.

Lie et al. (1994) studied this question.
