FEA prediction of crestal bone retention around dental implants

Bone and soft tissue response to two different dental implant systems was investigated through stress analysis and a canine implantation study. It was observed that in the collar region, when exposed to an 80 Newton axial load, the maximum crestal bone stress adjacent to the laser microtextured implant (LL) is lower than the stress in the bone adjacent to the S implant. In canine implantation study, the crestal bone height, which typically drops rapidly in the early implantation time periods, was found to be considerably higher in the LL specimens. It was demonstrated that laser microstructured surfaces show bone and soft tissue attachment features that are consistent with long term retention of alveolar crest bone.
