Preliminary Evaluation of a New Dental Implant Design with Finite Element Analysis

It is important to obtain mechanical coupling between dental implants and bone, because the lack of mechanical coupling may cause bone loss around implants. In this research, a new cylindrical dental implant composed of three parts was designed to offer favored mechanical environment for the bone. A special gap structure changed the means of the stress transmission and decreased the stress in the cortical bone around the neck of the implant. Through finite element analysis (FEA) of stress distribution in bone around implant-bone interface, the advantages of this new implant (reducing stress concentration in cervical cortex and satisfying varieties of clinical needs) were verified. The peak stress for the new design was about 30 percent less than that of the traditional implant and the flexibility of the design was also confirmed by changing the gap depth and the wall thickness.
