  • Richter, PW; Thomas, ME; Van Deventer, T (Bureau Scientific Publications, 1999-08)
    Solid freeform fabrication is a recent technology by which prototype devices can be manufactured layer by layer under computer control. This allows the production not only of individual devices of complex shape, but also ...
  • Thomas, ME; Richter, PW; Van Deventer, T; Crooks, J; Ripamonti, U (Bureau Scientific Publications, 1999-08)
    An improved strategy is described for the manufacture of macroporous hydroxyapatite bioceramics for bone substitute applications. This is based on a modified fugitive phase technique, which allows production of relatively ...
  • Schenker, R; De Beer, DJ; Du Preez, WB; Thomas, ME; Richter, PW (Bureau Scientific Publ, 1999-08)
    The technologies of reverse engineering and rapid prototyping are emerging as useful new tools in medicine. One application is of particular interest in orthopaedic, dental and reconstructive surgery. It involves the ...
  • Du Preez, WB; Richter, PW; Hope, D (2006-11)
    Eyeborn is an innovative hydroxyapatite orbital implant used to replace the eyeball of a patient who has lost an eye. A prosthetic eye cap is fitted on the front of the Eyeborn implant, restoring the patient's appearance ...

    Polyurethane (PU) may be suitable for various implant applications; however, it lacks bioactivity. Bioactivity allows for direct tissue attachment at the bio- interface, enabling implant fixation while preventing fibrous ...
  • Nilen, RWN; Richter, PW (Springer Science and Business Media, 2008-04)
    Biphasic calcium phosphate ceramics (BCP) comprising a mix of non-resorbable hydroxyapatite (HA) and resorbable b-tricalcium phosphate (b-TCP) are particularly suitable materials for synthetic bone substitute applications. ...
