The purpose of this study was to established the manufacturing process technology of an ultra-thin, multi-functional micro-implant(MFMI) that was optimized in fractured small animals, not mainly large animals. The test results showed a reckon type plate was more suitable than a straight plate because of excellent deformation energy. It was found that the structure of the hole and the screw could be fastened in all directions with the limited contact design of the threaded part cut off in 4 directions. It was possible to manufacture a reckon type plate reflecting the neck part of 2.0 mm width. It was confirmed that the plate hole could be stably and easily deformed and fastened without damaging the hole through the round type bending device.
