Inappropriate choice of dental implant type in relation to the detailed structure of bone at the site, and inadequate surgical technique has led to 5 % failure of dental implants worldwide. By using the finite element method, three typical implant insertion scenarios are modelled and evaluated in this chapter. The scenarios are implant thread forming, cutting and the combination of forming and cutting. The bone–implant system is modelled using three-dimensional finite element technique which incorporates realistic material properties in simulating the cancellous and cortical bone. The bone–implant contact is defined using ‘surface-to-surface’ discretisation and the arbitrary Lagrangian–Eulerian adaptive meshing scheme. In current practice many implant companies recommend thread cutting for normal bone and forming for compact bone so that implant stability can be ensured. Based on the findings of the present study, the combination of forming and cutting may also be recommended for clinical practice because it best matches the specified ideal stress level resulting in positive bone stimulation with minimum resorption. Stress information obtained in these three implant insertion scenarios will advance the understanding of bone response at an early stage of the osseointegration process and primary stability.
