CAD/CAM: A New Revolution in Forensics
Gayathri Ramesh · Forensic Research & Criminology International Journal · 2018
All humans have an identity in life. The cornerstone of forensic science is the positive identification of a human using his unique traits and characteristics. One of the most challenging aspects in forensic dentistry is the recognition, recovery and analysis of evidences and its matching with the suspects. A calculated and objective comparison utilizing technology would strengthen the validity of evidences in forensic dentistry. The use of advanced computer aided technology like CAD/CAM, has shown, in recent years, that it is possible to match DNA, Blood group antigens and tooth impression from a chewing gum retrieved to undermine the credibility of proof in a crime. The computer system of CAD/CAM can be used to construct a 3D-image of an object that has been retrieved from the crime scene by scanning the object and store all the information and can be used to assess the finding. This avoids any errors made by manual techniques which may not be always accurate. This review on CAD/CAM is described in this article with emphasis on its application in Forensics.
