Abstract
Background. Improving the implantation conditions in order to reduce the failure is always desirable for researchers.
The aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order
to introduce a novel simulation method to select suitable materials for dental implants.
Methods. In this research, drilling process was performed in the cortical bone of the mandible by finite element analysis
simulation. Then, a 3D model of the produced hole in the drilled site was derived and a dental implant model by ITI design
was inserted into the cavity. The space remaining between the implant and cavity was considered as a newly formed cortical
bone area. Implant loading was performed on two dental implants with different types of material. The change in the
volume of the cortical bone around each implant was considered a criterion for evaluating bone damage. Additionally, the
micromotion of dental implant in the mandible after implantation was used for investigating dental implant stability.
Results. After implant loading, the volume changes in newly formed cortical bone around Ti and Zr-2.5%Nb dental implants
were measured at 0.010809 and 0.010996 mm3
, respectively. Furthermore, micromotion of Ti and Zr-2.5%Nb dental
implants were measured at 0.00514 and 0.00538 mm, respectively.
Conclusion. This study showed that Ti dental implant creates better conditions than Zr-2.5%Nb dental implant in the maxillofacial
region
