    • All devices are recognized as foreign body materials once inserted in the living body, and they will all cause foreign body reactions. To determine the degree of integration, both qualitative and quantitative data are obtained by examining histological sections. This technique is the state of the art and has been so for decades. Quantitative analysis is important, but one cannot solely rely on data that computer programs rather rapidly generate. The qualitative examinations are of utmost importance. Tissue which has been properly fixed, processed, and maintained in the laboratories can be used for a broad range of histological analysis. This chapter presents some qualitative and quantitative state-of-the-art techniques used in relation to bone tissue analyses around biomaterials. Methods are described from fixation of tissue, preparation of sections, routine and new techniques adjusted to state-of-the-art techniques, and some complementary techniques. The importance of investigating the tissue reactions in various levels, from light microscopic to molecular, such as the localization of proteins as well as some quantification methods will be presented. In the future, we foresee even more complementary techniques to obtain more information regarding this tissue.

  • Improved osseointegration and interlocking capacity with dual acid treated implants: a rabbit study.
  • 2016

    • Aim To investigate how osseointegration is affected by different nano- and microstructures. The hypothesis was that the surface structure created by dual acid treatment (AT-1), applied on a reduced topography, might achieve equivalent biomechanical performance as a rougher surface treated with hydrofluoric acid (HF). Materials and methods In a preclinical rabbit study, three groups (I, II, and III) comprised of test and control implants were inserted in 30 rabbits. The microstructures of the test implants were either produced by blasting with coarse (I) or fine (II) titanium particles or remained turned (III). All test implants were thereafter treated with AT-1 resulting in three different test surfaces. The microstructure of the control implants was produced by blasting with coarse titanium particles thereafter treated with HF. The surface topography was characterized by interferometry. Biomechanical (removal torque) and histomorphometric (bone–implant contact; bone area) performances were measured after 4 or 12 weeks of healing. Results Removal torque measurement demonstrated that test implants in group I had an enhanced biomechanical performance compared to that of the control despite similar surface roughness value (Sa). At 4 weeks of healing, group II test implants showed equivalent biomechanical performance to that of the control, despite a decreased Sa value. Group III test implants showed decreased biomechanical performance to that of the control. Conclusions: The results of the present study suggest that nano- and microstructure alteration by AT-1 on a blasted implant might enhance the initial biomechanical performance, while for longer healing time, the surface interlocking capacity seems to be more important.
