Transcript of Facial Reconstruction

Clues! The skull provides clues to personal appearance. The brow ridge, the distance between the eye orbits, the shape of the nasal chamber, the shape and projection of the nasal bones, the chin's form, and the overall profile of the facial bones all determine facial features in life. The Steps!
1. Markers indicate the depths of tissue
to be added to the skull (a cast in
this case). Studies over the past century of males and females of
different ancestral groups determine
the measures of these depths.
2. Applying strips of clay, the artist
begins to rebuild the face by filing in around the markers.
3. The artist begins to refine features around the artificial eyes.
4. The lips take shape.
5. Facial contours have been smoothed
and subtle details added to accurately personalize the reconstruction. Important Considerations -Publicity is essential to the success of a clay facial reconstruction.
-A forensic sculptor is not qualified to determine the biological profile of the decedent; a forensic anthropologist should provide the profile before the reconstruction is completed.
-See examples of a forensic sculptor’s previous reconstructions to ensure his/her knowledge, experience and talent to produce a believable reconstruction
-The fee for a reconstruction is generally between $700-$2,000. Computer Facial Reconstruction Computer facial reconstruction has developed far enough to allow a virtual form of reconstructing the face from a skull, making it easy and efficient to travel from computer to computer. Such software allows for a 3D image/structure of the finished face to be rotated and moved around on a monitor.

Applying muscle and skin to the bone requires computer tomography (CT) scans of actual living people, which acquire images showing where bones cast shadows onto the skull and record bones and flesh in a 3 dimensional, view. By: Megan Bryan Facial Reconstruction In facial reconstruction, a sculptor, familiar with facial anatomy works with a forensic anthropologist, to interpret skeletal features that reveal the subject's age, sex, and ancestry, and anatomical features like facial asymmetry, evidence of injuries, or loss of teeth before death. The finished product only approximates actual appearance because the cranium does not reflect soft-tissue details . Yet a facial reconstruction can put a name on an unidentified body in a modern forensic case—or, in an archaeological investigation, a face on history. Introduction The disadvantages of facial reconstruction is that no sculptor is able to present an exact look alike. The advantage is a sculpture is successful if it aids in jogging someone's memory or can narrow down a search by excluding anyone whose face does not resemble the reconstructed face.
