title: [Resilience behavior of titanium implants with integrated maintenance-free biokinetic elements].
abstract: Good functional properties are essential in dental implantology. Bio-kinetics elements are imitating dental resilience. In this study a new kind of implants with maintenance-free shock-absorbing elements was introduced and their bio-mechanic properties were tested. The mobile implant (SIS Inc, Klagenfurt, Austria) is a self-cutting conical screw implant with an integrated bio-kinetic element. The shock absorber is a central part of the implant and a titanium ring obturates the shock absorbing unit in the implant. The resilience of the implant was tested by axial and excentric loading in a special testing unit. Furthermore a survival test of the elastic titanium ring in the most exposed cervical part of the implant was performed. The region was examined by scanning electron microscopy after 12 million loading cycles in the axial and radial direction. A progressive shock absorption was registered during radial and axial loading. The maximum movements were 0.06 mm in the axial and 0.16 mm in the radial direction. No signs of material destruction were seen in the electron microscopic analysis. Thus a maintenance-free bio-kinetic implant with progressive shock-absorbing qualities is presented.
