An attempt to create a standardized (reference) model for experimental investigations on implant’s sample.

The aim of this study was to determine, evaluate and measure strain of vertically loaded implant using the digital image correlation method. The Straumann® dental implant system with the SLActive® surface was used in this study. Implant was immersed in poly-methyl-methacrylate during his hardening process. After preparation procedure a sample of implant and poly-methyl-methacrylate was obtained. This sample was loaded using external load from 0 to 400 N. Maximum strain in the 4 mm surface layer was 0.30% whereas maximum strain in the 6 mm surface layer (opposite side) was 0.20%, detected in the marginal and apical part of implant-poly-methyl-methacrylate sample. Minimum strain measured by Aramis software was 0.01%, detected in the 4 mm surface layer. According to results obtained by Aramis data processing, the 4 mm surface layer indicated higher overall strain in apical direction with the strains of 0.18–0.21%. Increasing the load did not affect the value of maximum strain however, higher load influenced the overall strain concentration increased especially in marginal and apical part of the sample surfaces that surrounded lateral sides of implant body.
