Thanks to digital scanning and high - resolution 3D printing , a Crab subsister has been given a new jaw .
Shirley Anderson , a former mechanic who served in the Navy during the Vietnam War , was diagnosed with tongue cancer in 1998 , after he discovered a lump in his sass . The genus Cancer was treated with years of surgical procedure and radiation therapy , include a radium implant in his jaw that destroy a substantial share of his facial tissue , leaving him without a jaw or an Adam ’s orchard apple tree .
sawbones seek to fix the trouble by using muscle from his thorax to recreate the affected area , but their attempt failed . For many yr , he subsist without a jaw , find it impossible to eat solid food or lecture .
In 2012 , however , his story was discovered by Dr Travis Bellicchi , a maxillofacial prosthetics specialist at the Indiana University School of Dentistry . Although the scale of measurement of the prosthetics needed for Shirley ’s case was four times turgid than any of his late employment , Dr Bellicchi was determined to help .

Dr Bellicchi ab initio make a prosthetic jaw using traditional methods . However , the prosthetic lacked naturalistic detail , often slipped off the side , and was unbearably uncomfortable . So the surgeon seem to more late developments in digital scanning and three-D - grave proficiency .
“ The traditional cognitive process for impression , sculpting , mould - qualification , and aesthetic characterisation is a laborious task , ” Dr. Bellicchi explained in apress going . “ I knew there was a motivation for a digital solution . ”
With the assist of Professor Zeb Wood , a lecturer at the School of Media Arts and Sciences , Dr Bellicchi make a digital model of Shirley ’s face using off-white structure data point from a CT CAT scan and a 3D CAT scan of his facial features . The team used the 3D printer atFormlabsto create a three - dimensional mold of Shirley ’s face , which they then used for the prosthetic .
“ They really could n’t believe how easy it was , " said Cade Jacobs , an Indiana University bookman who usedZBrush3D - grave software package to design the prosthesis . " They had been struggling to get the same resultant for a farseeing time when they were using the traditional appendage . "
Not only is this new prosthetic far more realistic , it is also more breathable , wakeful , and comfortable . In honor of Shirley , Dr. Bellicchi has dubbed this new digital method of creating artificial facial parts “ The Shirley Technique . ” He is now using these novel skills to help a handful of other patient , admit a human being who miss his ear .

Dr Bellicchi add up : “ It ’s a privilege to have an chance to work with a affected role like Shirley because Shirley makes the process collaborative . Shirley participates in my work to improve his prosthesis . Although it ’s likely the most significant challenge I will ever present in my prosthetic career , I think it may be the most rewarding . ”
Although Shirley is still unable to speak , he recently wrote on his whiteboard : “ I have my life story going just as I need . ”
