Characteristics and biological responses of selective laser melted Ti6Al4V modified by micro-arc oxidation.

Background/purpose: Additive manufacturing (AM) technology, such as selective laser melting (SLM), has been used to fabricate medical devices of Ti-6wt.% Al-4wt.%V (Ti6Al4V) alloys in dentistry.

Engineering three-dimensional structures using bio-inspired dopamine and strontium on titanium for biomedical application.

The excellent mechanical properties and chemical stability of titanium and its alloys have led to their wide use as a material for dental and orthopaedic implants. However, the bio-inert nature of these materials must be overcome to enhance cell affinity and cell function following implantation. Effective implants require strong interfacial bonding, mechanical stability, osteoblast attachment, enhanced spreading and growth during early stages, and induced differentiation and mineralization in later stages.

Comparison of osseointegration on various implant surfaces after bacterial contamination and cleaning: a rabbit study.

Purpose: To examine the osseointegration of various implant surfaces after bacterial contamination and cleaning.

Materials And Methods: Four types of implant surface were manufactured: machined (M); plasma-spray hydroxyapaptite (HA); sandblasted, large-grit, acid-etched (SA); and titanium anodic oxide (TAO) were manufactured. The surface characteristics of these implants were determined using a scanning electron microscope, an energy dispersive spectrometer, and a contact profilometer.
