Through this study, three-dimensional (3D) models of craniofacial including soft tissue and prosthesis were constructed from computed tomography (CT) image datasets. The implant models were developed using computer-aided design (CAD) software and all models were analyzed via finite element analysis (FEA) software.
Finite element analysis was performed to investigate the stress transfer of various thread profiles and material properties of dental implant system to the surrounding mandibular bone, followed by statistical analysis to examine the relationship of the two factors.
In this paper, effect of the implant thread profile on
the stability and osseointegration at the peri-implant bone were evaluated by finite element analysis. These study include five different common threads profile of implant body – buttress, reverse buttress, V-shape, sinusoidal and square – that were evaluated via finite element analysis. Three dimensional model of a mandible was reconstructed from CT dataset and a region of interest was selected at the left side around the first molar. Result showed that the reverse buttress and V-shape thread offer high stability by provide less micromotion at the dental implant body.
