6.3.2 Introduction
In recent years, rapid prototyping (RP) has been used to build highly accurate
anatomical models from medical scan data. These models have proved
to be a valuable aid in the planning of complex reconstructive surgery,
particularly in maxillofacial and craniofacial cases. Typically, RP is used to
create accurate models of internal skeletal structures on which operations
can be accurately planned and rehearsed (1, 2, 3, 4). Such models have been
successfully used for positioning osseointegrated implants. Osseointegrated
implants are titanium screws attached directly to a patient’s bone structure
