Evaluation of Biomechanical Characteristics of Dental Implant

In evaluation of the long-term success of a dental implant, the reliability and the stability of the implant-abutment and implant bone interface plays a great role. In general, the success of the treatment depends on many factors affecting the bone-implant, implant-abutment and abutment-prosthesis interfaces. In the literature, many researchers have investigated biomechanical and biophysical mechanisms of the implant. However modal analysis of implants with abutment under dynamic loading has not investigated formally. In this study, natural frequencies and modal behaviors of the three types of cylinder-type titanium implants were investigated. In this model, the implant was embedded into a cubic section of bone. A torsional behaviour and axial mode of vibration were found for type II, whereas a bending behaviour was dominant for type I. The implant dimensions influence the values for the resonance frequencies. Our results show that the resonance frequency of the implant with the type I increased irregularly from 17.52 kHz to 23.44 kHz, and from 24.78 kHz to 32.44 kHz for the type III .
