Özet
The aim of this study was to compare the stress values on the implant caused by the change in the implant diameter, length, and the angle of the implant placement. Thus, our goal was to determine the correct implant preference with regard to the appropriate diameter, length, and insertion angle. In our study, a total of 6 different types of implants with 2 different diameters (3.7 mm and 4.7 mm) and 3 different lengths (5 mm, 10mm, and 13mm) belonging to these diameters were selected. These 6 different sized dental implants were applied to the maxilla and mandible, vertically and angled, and a total of 24 models were obtained. The maximum and minimum principal stress values in cortical and cancellous bone were determined as a result of the applied forces. The maximum and minimum von misses stress values and the places where they occurred were determined as a result of the application of the vertical and oblique (30 °) forces, with a total of 300 N from the 3 different occlusal points by placing Zimmer brand implants that were 5, 10, and 13 mm in length and 3.7 and 4.7 mm in diameter on the maxilla and mandible separately at an angle of 30 °. Taken together, in all models, under each loading condition, as the implant diameter and length increased, the stress levels in the bone and implant decreased. Thus, implant diameter is more effective than implant length at changing the stress values. There was a significant increase in the stress levels of the cortical bone and implants in the oblique loading models compared to the vertical loading models. © 2021. All rights reserved.
