Long term it should not be a problem, even at most majors. It was not a lapse of ethics or judgement (like a criminal issue), and everyone understands that sometimes the CFI simply can't ensure a positive outcome. You will have to explain it carefully at a regional interview, but you are by no means the first CFI to bend an airplane. Accept responsibility, talk about what you learned, and don't try to blame it all on the student. If the student froze and you had to fight for the controls, there might not have been much you could do...there is no requirement that a CFI be stronger than his students.
