3D打印技術助癌病人製新下巴

04-07-2016

 現時的3D打印技術發展愈來愈發達,美國印第安納大學牙醫學院一名外科醫生使用3D打印技術,為一名癌症病人造出一個人工下巴。

英國《電訊報》報道,癌症病人安德森在1998年,獲診斷出在舌頭上長了一塊腫瘤,醫生曾經利用他胸口的肌肉,嘗試重新製造面部下半部分,但手術失敗。

醫生亦曾經試過以陶土製造一個人工下巴,但由於陶土太大及太重,每次只可以配戴數小時,導致安德森只可以戴上面罩,亦不能進食固體食物。

最終醫生與他的團隊,利用硅酮以3D打印技術,打造更輕的下巴,讓安德森能長時間配戴,亦無礙他的呼吸。

過去已經有六位病人受助於這種治療方法,包括一位需要更換耳朵的病人。

Cancer patient receives a 3D-printed jaw

 

Abigail Watson/Indiana University
If you lose your lower jaw to cancer, you don't have many options for prosthetics. At that size, traditional clay is so heavy and unwieldy that you can only wear it for a few hours at a time. Indiana University's Dr. Travis Bellicchi and team have developed a much better alternative, though. He recently gave tongue cancer patient Shirley Anderson a 3D-printed jaw after losing his natural jaw to the side effects of radiation treatments. The digitally-modeled piece is not only much lighter, but far more natural-looking — the creators could create more natural borders and account for fine details like skin pores. The result is good enough that Anderson could comfortably wear the prosthesis in public without drawing significant attention.

Crucially, the technique is already paying dividends beyond Anderson. A man who lost an ear to an industrial accident got a natural-looking replacement just 6 weeks later, and there are five other patients who've received 3D-printed prosthetics. There may well be a time in the near future where the technology regularly helps patients restore missing features.
