Sin­ga­pore team de­vel­ops de­vice for faster jaw re­con­struc­tion

BioSpectrum (Asia) - - Science News -

A team of re­searchers from the Na­tional Den­tal Cen­tre Sin­ga­pore, has de­vel­oped a ti­ta­nium mo­du­lar endo-pros­the­sis that can be used to re­place the af­fected part of the lower jaw. The cur­rent method uses a bone from the pa­tient’s lower leg. Af­ter the sec­tion of the jaw is re­moved, the pro­ce­dure in­volves af­fix­ing the de­vice into holes drilled into the bone stumps and fix­ing screws to se­cure it to the jaw. Cur­rently, sur­geons re­move a bone in the pa­tient’s lower leg along with the blood ves­sels and shape it to fit the jaw of the pa­tient. This re­quires an op­er­a­tion of up to 12 hours, three weeks of hos­pi­tal­i­sa­tion and a re­cov­ery pe­riod of two weeks, with pos­si­ble com­pli­ca­tions such as in­fec­tion, and ex­ten­sive scar­ring on the leg. The new way of re­con­struc­tion will lead to a shorter op­er­a­tion of four to eight hours, fewer post-op­er­a­tive com­pli­ca­tions, and a faster re­cov­ery of three days in­stead of two weeks. The Na­tional Den­tal Cen­tre Sin­ga­pore team has filed a patent ap­pli­ca­tion and clin­i­cal tri­als are ex­pected to be­gin by 2020. They are also ex­pect­ing to com­mer­cialise the prod­uct by 2025.
