“…[32] Despite the differences in the osseointegration times, the bone characteristics, the size of implants or other less influential parameters, the overall patterns of healing are similar to those found in other studies using the sheep model. [33][34][35] All micro-CT parameters measured showed unambiguous increments in the bone turnover on and around the calcium modified surfaces with respect to the controls. In general, these test surfaces achieved more vertical bone growth, both ectopic and towards the marrow.…”

“…In using a similar surface to SLA, a recent study showed that the implant surface morphology seemed to influence the increase of osteogenesis. These implant surfaces, characterized by moderately deep cavities that are very similar to the osteocyte lacunae, could act as a microscopic scaffold for mesenchymal and/or osteoblast-like cell adhesion (Franchi et al 2007).…”

Two‐ and three‐dimensional profilometer assessments to determine titanium roughness

et al. 2009

In this study, a comparative topography analysis of titanium (Ti) surfaces was performed using two- (2D) and three-dimensional (3D) profilometers. Ti samples were either only sandblasted (SB) using Al(2)O(3) particles or were SB and received an additional chemical treatment using a solution of 4% HF (SLA). Samples with no treatment were used as a control group (C). Therefore, three different surfaces were evaluated: SB, SLA and C. The Ti surface topographies were evaluated by scanning electron microscopy. An Ra roughness measurement was performed on each Ti sample by 2D and 3D profilometers. Surface roughness was also characterized using amplitude, spatial and hybrid 3D parameters. 2D and 3D profilometer analyses produced very close results. Mean Ra values range from 0.19 to 0.25 (C, p<0.05), 0.84 to 0.99 (SLA, p<0.05) and 0.98 to 1 microm (SB, p>0.05). The statistically different Ra values depending on the surface studied may be explained by methodological and technical differences. Also, 3D profilometer seems to be the more appropriate analytical method for measuring the roughness of Ti surfaces because it also describes surface organization.

“…Also the implant surface treatment modalities increase the primary stability, since an increase in roughness may improve the contact between the bone and the implant. In addition, in vitro studies have shown that the sandblasted and etched implants promote the osteogenesis by improving the osteoblastic activity, as compared to the machined ones (8)(9)(10). Regarding the quantity and the quality of the bone, there is a consistent literature showing that most of the failures in implantology are more linked to the quality than to the quantity of bone.…”

SUMMARYObjective. In the last few decades the implantology has achieved excellent results in the prosthetic rehabilitation of the partially or totally edentulous patients. The clinicians, given the pressing demand by patients, must deal with the situations in which the lack of the availability and sometimes the low quality of the bone can lead to the treatment failure. Although the manufacturers recommend to follow codified surgical protocols, alternative techniques of preparation, apt to ensure a better primary implant stability, have been developed. The aim of this study was to determine in vitro, by using the resonance frequency (Osstell mentor), which technique of implant site preparation (piezo surgery, conventional, under-preparation, bone compaction, osteodistraction) is able to improve implant stability of type IV cancellous bone. Methods. 10 pig ribs were prepared, and a surgical pre-drilled and calibrated guide for proper implant placement was used. On each rib, 5 implant sites were prepared, one for each technique. Results. One-way ANOVA did not show statistically significant differences among the "implant stability quotient" (ISQ) values of the 5 techniques utilized. Conclusions. Thus, in light of these results, in the clinical practice of the type IV bone one technique is replaceable with the others, as none of them improves implant stability. The choice should instead be directed to the technique that accelerates the healing process and the osseointegration.
