“…In addition, it has been suggested that the microstructure of the base substrate needs to be optimized in order for the nanostructure to present maximal effects (Löberg et al. ). Thus, the aim of this study was to investigate how osseointegration was affected by different surface structures treated by oxalic and hydrofluoric acid treatment compared to a surface structure created by coarse blasted particle treated with only hydrofluoric acid.…”

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 (S a ). At 4 weeks of healing, group II test implants showed equivalent biomechanical performance to that of the control, despite a decreased S a 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.

“…Atomic force microscopy (AFM) technique that enables nanoscale mapping (De Oliveira et al, ; Löberg et al, ; Sharma et al, ) have been used to investigate the 3D topographic features in different studies of the ([Ce‐TZP]‐[Al 2 O 3 ]) dental alloys (Podzorova et al, ). Now there is a question about the characterization of the 3D surface morphology of ([Ce‐TZP]‐[Al 2 O 3 ]) dental alloys processed with/without Ca +2 modifier.…”

The objective of this study was to characterize the three-dimensional (3D) surface micromorphology of the ceramics produced from nanoparticles of alumina and tetragonal zirconia (t-ZrO2) with addition of Ca(+2) for sintering improvement. The 3D surface roughness of samples was studied by atomic force microscopy (AFM), fractal analysis of the 3D AFM-images, and statistical analysis of surface roughness parameters. Cube counting method, based on the linear interpolation type, applied for AFM data was used for fractal analysis. The morphology of non-modified ceramic sample was characterized by the rather big (1-2 μm) grains of α-Al2O3 phase with a habit close to hexagonal drowned in solid solution of t-ZrO2 with smooth surface. The pattern surfaces of modified composite content a little amount of elongated prismatic grains with composition close to the phase of СаСеAl3О7 as well as hexahedral α-Al2O3-grains. Fractal dimension, D, as well as height values distribution have been determined for the surfaces of the samples with and without modifying. It can be concluded that the smoothest surface is of the modified samples with Ca(+2) modifier but the most regular one is of the non-modified samples. A connection was observed between the surface morphology and the physical properties as assessed in previous works.
