Implant, N, a thing implanted in something else, especially a piece of tissue, prosthetic device, or other object implanted in the body.

Prosthetic, N, An artificial body part; a Prosthesis.

Artificial, N, made or produced by human beings rather than occurring naturally, typically as a copy of something natural.

Device, N, a thing made or adapted for a particular purpose, especially a piece of mechanical or electronic equipment.

Naruto's Prosthetic arm is considered a device cause it has a purpose and is definitely a prosthetic as you guy's have called it. So is what Obito and Madara had. So again, there's no proof what Naruto had was any different. You can't even prove what it looks like or if it has anything mechanical about it. You are going off a different hand, Momoshiki's prototype. Momoshiki's hand is not the Hashirama Hand. For all you know, Naruto just ripped it off, tried the prototype, then removed it and put back the Hashirama hand like Madara did with a White Zetsu clone's hand.
