Well my impatient friend, scientists have something better to do. Like create the first 3D printed titanium human jaw and successfully implant it into a female patient.
BOOM.
So what happened was this woman had osteomyelitis (bone infection) that was so bad her lower jaw couldn't be saved. The awesome folks at Hasselt University Biomed (in Belgium) has a functional morphology research group and decided to help out. Functional morphology is the study of why things are shaped the way they are shaped, and how that shape affects the function of the thing.
So this research group created a customized 3D printed titanium jaw. They gave her an MRI so that they could customize the jaw, and built it in just two days.
This woman had a complete lower jaw implant, and it restored vital functions (breathing, speech, chewing, and sensation) as well as aesthetics (her jawline still looks like her). It's an incredible step forward with implants and health care. While current technologies limit the amount of personalized prosthetics that can be made, this could be commonplace in the near future, and represents a huge step forward in medical technology. This technique could be used in hip prosthetics, as well as knees and elbows, even spinal inserts.
It's all very exciting.
