[Use of the computer in dentistry: video superimposition and facial reproduction using the expedience of the computer interface].

Abstract

Both video superimposition and computer facial reproduction play a useful role in the process of identification, particularly in the early stages of an investigation or when other more definitive methods may not be available. Video superimposition combined with a computer overlay technique can be used to establish whether a skull outline matches an image of a missing person, being a photograph, slide or videoimage. A computer driven robot can be used to simplify the alignment of the skull with the position of the head on the image. Craniofacial or facial reproduction are used in both 2D or 3D to produce an image which can be used for identification purposes.
