Nanomodified Peek Dental Implants: Bioactive Composites and Surface Modification—A Review

Figure 2

A schematic diagram of the process of melt-blending to produce bioactive PEEK composites. First, the PEEK powder and nanofillers are codispersed in a suitable solvent. The solvent is then removed and the mixture is placed in suitable moulds and heated to a temperature above the melting point PEEK under high pressure in a mould (so-called compression moulding). Upon cooling, the resultant material is composite of PEEK and the fillers. The solid composite is then machined to provide shape or surface characteristics suitable for a dental implant.
