Biological characterisation of materials produced by powder injection moulding (PIM) has been conducted, with the aim of promoting the use of PIM materials for dental applications to widen the potential applications of PIM. The biocompatibility trials focused on two alloys: the titanium alloy TiAl6V4, a well known biocompatible metal used for dental implants in contact with bone tissue; and a homogeneous 90Ti/10ZrO(2) composite applied for abutments in contact with epithelial tissue. It is concluded that PIM allows the production of materials with good biocompatibility with respect to osseointegration as well as soft tissue adhesion, compared with traditional materials for dental practice.
