Abstract
Three models with single implant placed in posterior mandibular edentioulus section were constructed using solidworks software. In each model only one implant material was used, therefore a zirconia model. TiNbZr model and titanium model were obtained. All variable rather than implant material was standedized for all the models.
The material properties for zirconia implant, TiNbZr implant, titanium implant, compact bone, cancellous bone, feldspathic porcelain and mucosa were indentified.
Each model was subjected to two types of load applied separately in two different times. One load was vertical load applied to the central fossa of the crown. The other one was oblique load applied to the lingual incline of the buccal cusp of the crown. The model was restrained at its inferior border to avoid total body displacement.
Using ANSYS mechanical software, the models were meshed with adaptive coarse mesh and analysis was conducted with iterative method.
The stresses at the cervical, middle and apical bone parts around each implant were recorded, the result were collected, and comparison was made.
The result, showed that zirconia implant model induces the least amount of Von Misses Stresses in the cervical portion of the peri-implant bone and the highest amount of stresses within the middle and apical parts. While the opposite occurred with the (TiNbZr) implant models
