Surface Characteristics and Cell Adhesion: A Comparative Study of Four Commercial Dental Implants

Temporal Changes in the Causes of the Observed Oxygen Decline in the St. Lawrence Estuary

“…A first possibility is that the intrusions are controlled by the North Atlantic Oscillation (NAO, Loder et al, 2001;Pershing et al, 2001) or the Atlantic Meridional Overturning Circulation (AMOC, Claret et al, 2018;Thibodeau et al, 2018). A slower AMOC is expected under climate change (Stouffer et al, 2006) and was recently found in some observational studies (Caesar et al, 2018;Thornalley et al, 2018). A positive phase of the NAO or a slowdown of the AMOC would lead to a contraction of the subpolar gyre (e.g., Lohmann et al, 2009;Taylor & Stephens, 1998), a northern shift of the Gulf Stream (Joyce & Zhang, 2010) and a reduction of the transport of LCW southwest of the Grand Banks, leading to an increased contribution of NACW over LCW to the Cold Slope waters (Townsend et al, 2015).…”

Dental Implant Macro‐Design Features Can Impact the Dynamics of Osseointegration

“…The OsseoSpeed implant was selected to serve as control, an implant having a long‐term scientific documentation, a significant level of clinical success, and an implant surface with osteogenic properties . The OsseoSpeed implant is the next generation implant of its predecessor, TiOblast, because it presents the same titanium surface properties but the innovative concept of surface fluoride modification that is claimed to induce bioactive properties . The aim of the study was to compare the clinical performance of the OsseoSpeed and the Aadva implant types in the in vivo pig model.…”

Effect of high glucose levels and lipopolysaccharides‐induced inflammation on osteoblast mineralization over sandblasted/acid‐etched titanium surface

“…Indeed, the improvement in the implant surface physical structure has become an important aspect to be considered, as increased surface roughness may promote osseointegration . For instance, the sandblasted/acid‐etched (SLA) titanium surface has been processed to a high degree of bioactivity and has demonstrated enhanced cell adhesion, proliferation and osseointegration . Clinical studies have reported that both the hydrophilic and hydrophobic SLA surfaced implants function well and display high survival rates following implantation .…”

“…14 For instance, the sandblasted/acid-etched (SLA) titanium surface has been processed to a high degree of bioactivity and has demonstrated enhanced cell adhesion, proliferation and osseointegration. 17 Clinical studies have reported that both the hydrophilic and hydrophobic SLA surfaced implants function well and display high survival rates following implantation. 18,19 Additionally, hydrophilicity of active SLA surfaces improves biocompatibility, which is also responsible for fighting bacterial infection as it promotes downregulation of pro-inflammatory cytokines and consequently modulates inflammation.…”
