FEA experiments are conducted in a model and a generated model from in vivo data CBCT scanning. The model consists of a crown, implant, two neighbour teeth, and cortical and cancellous bone with various scenarios of loading. The mechanism of stress distribution was evaluated to simulate pre- and post-loading. The results show that an increase in cortical thickness will increase the stress transferred into the surrounding area. This condition can protect the bone from suffering from high stress due to loading, which means that it is good for clinical purposes. Inversely, the friction coefficients decrease the ability to transfer the stress; hence, the dental implant with a high friction coefficient will protect the bone from overloading the stress due to external loading. The external loading can cause the micro motion in the dental which is larger than neighbour teeth.
