Wang Na, who was born without an upper jaw bone, eats a biscuit after undergoing cosmetic surgery in the dental hospital subordinated to the Fourth Military Medical University in Xi'an, Shaanxi province, May 17, 2010. Fitted with new teeth, the 22-year-old, who began receiving treatment four years ago, is learning to chew, speak and generally get used to her brand new face. She was abandoned after birth and adopted by a couple, who scoured the province for appropriate therapy methods to help her. [Photo/Xinhua]
