Vizard? Quincy? Fullbring? Zanpaktou?

-Is there a way to cure hollowfication?
-Also is there a way to cure full vizard?
-Do quincys lose their powers after final form? If so is this permanent unless granted power from another quincy such as iryu and his father?\
-Is there a way to destroy a fullbring and make that person an ordinary human?
-Can a zanpaktou be fully broken and die without it's shinigami?

1) Visored seemed to be only cure to being hollowfied. Rather than becoming a hollow and rampaging the person retains their humanity.

2)Visored being a controlled state, there is no real danger to the user. Healing might be possible, but unsure to how.

3)Quincy lose their power after the form granted from removing their glove forcefully. The restoration process Ishida's father used is indeed the method to restore them

4)From the manga it would seem that if a Fullbringer gives their power to a shinigami they become human. One could guess it's similar to how a shinigami can give powers to a human to make temporary shinigami. Although for Fullbring seems more permanent.

5) With what has happened with Renji, Ikkaku, Ichigo, and the Sword fiend arc you get a plausible answer. Once the wielder is unconscious the zanpukto returns to it's normal sealed form. A zan can be damaged, but will recover over time. Finally if the user falls/dies the zanpukto can perish with along with the wielder.
