The Method of Digital Holographic Interferometry for Research of Dental Implants

The method for measuring the axial deformations of dental implants with the use of digital holographic interferometry is developed. The optical scheme for registration of digital holograms of diffuse objects is developed and optimized. The software has been developed for recording, processing and reconstruction of digital holographic interferograms. Special equipment has been created for fastening and dosed load of dental implants. The experimental dependence obtained during the study shown that popular today titanium abutments take less deformation under mechanical load than abutments from ZrO 2 . Also, the same dependency for the implant length is shown.
