“…This value is extremely small and is safely below the citotoxicity level of Ti, reported as 5 ppm [44].The respective corrosion rate for the basal planes of nanostructured Ti is estimated as ~1.65 g cm -2 year -1 or 0.03 g cm -2 week -1 . Usually, the released Ti is found in much larger concentrations in tissues at close distance to the implant (≤1000 m) than in blood or saliva (Table 6), therefore it is safe to assert that the release rate measured in this work improves various reported values [45][46][47][48][49] …”

“…No negative effects from aluminum (Al) ions were seen on the peri-implant bone tissues, even if blasted surfaces contained a significant amount of aluminum, most probably because with blasted implants only a limited and transient release of Al ions occurs. 32 Wennerberg et al 33 found no correlation between ion release and surface roughness levels of commercial implants.…”

Development of an optimal interface between bone and orthopedic or dental implants has taken place for many years. In order to determine whether a newly developed implant material conforms to the requirements of biocompatibility, mechanical stability and safety, it must undergo rigorous testing both in vitro and in vivo. Results from in vitro studies can be difficult to extrapolate to the in vivo situation. For this reason the use of animal models is often an essential step in the testing of orthopedic and dental implants prior to clinical use in humans. This review discusses the reasons, the importance, and the research carried out in rabbits in our quest to develop a dental implant ideally suited for human bone.

“…(a) Sand-blasted largegrit acid-etched (SLA), which involves sandblasting followed by acid etching and then dry-storage in air within sterile packaging. Moderate roughness can promote cellular differentiation and osteogenesis, [15][16][17][18][19] while surface energy/ wettability provides the driving force for bone cell adhesion and proliferation and reinforces matrix protein adsorption, ultimately affecting the quality of the osseointegration of the implant. 13,14 These two methods generate different surface structures, which result in different surface roughnesses and energy/wettability.…”

Background: Titanium-zirconium alloy (TiZr1317) is a new material used for biological implants.There are several studies on the effects of TiZr implants on the biological characteristics of human bone mesenchymal stem cells (hBMSCs).Purpose: The purpose of this study was to investigate the biological responses of hBMSCs to implant holes affected by the physicochemical properties of oral implants (Ti SLA , Ti SLActive , TiZr SLA , and TiZr SLActive ). Materials and Methods: Grade 4 Ti and TiZr (13-17% Zr) substrates were modified by sandblasted large-grit acid-etched (SLA) or hydrophilic sand-blasted large-grit acid-etched (SLActive), resulting in four types of surface with complex microstructures corresponding to the commercially-available implants SLA, RoxolidSLA, SLActive, and RoxolidSLActive (Institute Straumann AG, Basel, Switzerland). Physicochemical properties were detected and the biological responses of hBMSCs were observed.Results: Surface morphology characterization by scanning electron microscopy and atomic force microscopy revealed differences between the four groups. SLA ctive had higher surface energy/ wettability than SLA, indicating that increased surface energy/wettability can promote the absorption of osteogenic proteins and enhance osseointegration. hBMSCs seeded on SLActive substrates exhibited better performance in terms of cell attachment, proliferation and osteoblastic differentiation than cells seeded on SLA.

Titanium release from implants prepared with different surface roughness

Abstract: At a level relevant for commercial oral implants, no correlation was found between increasing roughness and ion release, neither in vitro nor in vivo.
