In this paper the finite element procedure is used to evaluate various bone, implant and loading parameters for their influence on the stress distribution within the bone, in particular in the mandible. The methodology and analysis techniques employed to enable accurate modelling of the implant and bone systems are discussed in the companion paper (Part I). The analysis results show that an increase in the Young?s moduli for the cancellous and cortical bone yields elevated stress magnitudes in the bone. Thinner cortical bone results in elevated stress levels within itself as well as in the cancellous bone. In both ...

Thinner cortical bone results in elevated stress levels within itself as well as in the cancellous bone. In both cancellous and cortical bone, t he implant length demonstrates to be more influential, in terms of differences between the minimum and maximum stress values, as compared to the diameter. The masticatory forces exhibit a more significant influence on the stress than all the other parameters. Therefore loading should be considered an imperative factor when planning an i mplant placement.
