Abstract - The aim of this article is to illustrate and discuss current methods applied in the analysis of biomechanical components in dental applications. For illustration purposes, the strain development of a non-passively ï¬tting implant supported ï¬xed restoration was evaluated using the four techniques: photoelastic examination, strain gauge measurements, ï¬nite element analysis, and three-dimensional deformation analysis. Photoelastic analysis only allowed for a raw estimation of the strains evoked by superstructure ï¬xation. Quantitative results could be derived from both strain gauge measurements and three-dimensional deformation analysis which could then be used to simulate the loading situation around the supporting implants.
