This research integrated finite element analysis (FEA) and optimum design to obtain a fast, accurate and automatic optimization system for the design of an ultrasonic horn. The optimization system was developed to achieve uniform amplitude distribution on the output surface of a block shaped horn for the ultrasonic plastic welding. Agreement between the experimental and numerical data proved that this optimization system was efficient in the design of ultrasonic horns.

Objectives: In this study, dental implants with three different tooth pitch are designed and tested under static loads and fatigue analysis. In order to reveal the strengths of the different implant designs in dental implant application, the experimental setup where real physical environments were created experimental data was obtained, and these data were compared with numerical data. Materials and Methods: It is difficult to find an analytical solution for problems involving complex geometries. For this reason, numerical methods such as finite element analysis (FEA) are used. For compared finite element results and experimental analysis a new experimental setup has been created to simulate the physical conditions inside the mouth. In this arrangement, the temperature is close to ideal with the acidic environment inside the mouth. Firstly, the geometrical implant system determined on the CNC machine was produced. Results and Conclusion: In this study, dental implant research with 3 different screw pitch was performed. The results obtained from the experimental results were compared with the results obtained from the numerical analysis and it was observed that the accuracy of the numerical analysis was approximately 95%. It was observed that the tensions were less in the dental implant with higher number of screw pitch. In terms of the difficulty of experimental studies, finite element analysis saved both time and money. Thanks to this method, different scenarios can be applied to the optimum design of the dental implant and it can be designed in a computer environment before applying to the patient.
