Denise Vicentin (2-R), who lost her right eye and part of her jaw to cancer, embraces a member of the medical staff of doctor Rodrigo Salazar-Gamarra (L) after receiving a digitally-engineered prosthesis, in Sao Paulo, Brazil, on December 3, 2019. Researchers at Paulista University are employing smartphones and 3D printing to create digital facial impressions to make silicone prostheses. The team specializes in maxillofacial prosthetics, a branch of dentistry focused on treating people disfigured by birth defects, disease or trauma. The pioneering method has slashed costs and halved production times. (Photo by Nelson Almeida/AFP Photo)
