[Implant optimization with help of numerical finite element studies].
During the past years numerical finite element studies have become more and more important for the evaluation of stress effect on the implant surrounding bone. Based on the results of recent researches and finite element studies B.I.T.-Implants were developed from IK-Implants, which have been clinical successful for over 12 years. The result are two different screw implants with a very homogeneous and tolerable stress distribution in bone.
