I got a decent cut in my finger the other day. By today it has healed itself completely and the pattern looks undistrurbed. My question is, how does our body know the pattern to regenerate and how much damage has to be done to disturb the pattern regeneration?

I touched a hot frying pan when i was a kid. It was one of those “don’t touch, it’s hot” , so of course I had to ttouch it. It didn’t seem bad or even large (apple seed sized). 30+ years later and where the blister was I don’t have any lines or whorls. Just little bumps.
This is a pretty good explanation:

The short version is friction from pressing your fingers up against stuff in the womb makes the skin fold up a little and form ridges. That’s why identical twins don’t have the same fingerprints.
The really odd part is they can wear out, and then need to grow back. (or you can just have bad luck with a belt sander)
As for changing the pattern as far as I know you would have to bust up the skin enough where it forms scar tissue, and interrupts the pattern.
The DNA, the stuff that decides what your fingerprints are from conception, makes sure they heal the same as they were, but it’s never 100% accurate. That said, the only way to make a finger print unrecognizable in a scan would be to slice, burn, or dissolve your fingertips off.
I can honestly say that I incurred whatever amount of damage that is, on both hands. Some years back my professional license required me to be fingerprinted, but weren’t able to get satisfactory prints because I don’t really have any! I have an autoimmune thing that raises all sorts of hell with my hands, and it turns out it throws a wrench in the whole fingerprinting thing too. The pads of my fingers look like they’ve been sanded down, lol.
If the cut is clean, then ofcourse your finger print pattern will be the same as it is. But if you completely scalp off your fingger print then it wont be back, not by natural regeneration atleast
If you wonder why its because there is no stem cell that can be dedicated to regenerate a finger print
