Maxillofacial prostheses are usually fabricated on the models obtained following the
impression procedures. Disadvantages of conventional impression techniques used in
production of facial prosthesis are deformation of soft tissues caused by impression
material and disturbance of the patient due to.Additionally production of prosthesis
by conventional methods takes longer time. Recently, rapid prototyping techniques
have been developed for extraoral prosthesis in order to reduce these disadvantages
of conventional methods. Rapid prototyping technique has the potential to simplify
the procedure and decrease the laboratory work required. It eliminates the need for
measurement impression procedures and preparation of wax model to be performed by
prosthodontists themselves In the near future this technology will become a standard
for fabricating maxillofacial prostheses. (Eur J Dent 2011;5:472-477)
