Abstract
Background: Although it is important to elucidate the deformation distribution of alveolar bone around a dental implant, there are some disadvantages in the existing experimental methods such as strain gauge method, photoelasticity method, etc. Therefore, an advanced experimental technique is required not only for problems but also for showing the validity of numerical analysis such as finite element analysis.
Objective: A new advanced experimental technique combining a bone model and digital image correlation (DIC) method is proposed to enable systematic, quantitative evaluations.
Method: A laminated test block (SAWBONES, WA, USA) having the same bilayer structure as actual bone was employed as the bone model specimen. The DIC method was used to visualize the displacement and strain distributions of alveolar bone around a dental implant.
Results: The new proposed experimental technique made it possible to analyze the deformation distribution around a dental implant systematically and quantitatively.
Conclusions: The proposed experimental technique can be used to assess the deformation distribution behavior of alveolar bone around a dental implant systematically and quantitatively.
