In this paper,we consider the Böhmer-Vandersloot(BV)model of loop quantum black holes obtained from the improved dynamics approach.We adopt the Saini-Singh gauge,in which it was found analytically that the BV spacetime is geodesically complete.We show that black/white hole horizons do not exist in this geodesically complete spacetime.Instead,there exists only an infinite number of transition surfaces,which always separate trapped regions from anti-trapped ones.Comments on the improved dynamics approach adopted in other models of loop quantum black holes are also given.
