Bilateral dislocated fractures of mandibular condyles result in...

Anterior open bite
Improved mandibular movement
Decreased oral opening
Enhanced chewing ability

The correct answer is: Anterior open bite

When the mandibular condyles of both sides of the jaw are dislocated, it results in an anterior open bite where there is a gap between the upper and lower front teeth when biting down. Option B is incorrect because the mandibular movement will actually be limited and hindered due to the dislocation. Option C is also incorrect because dislocated fractures can result in a wider oral opening due to the separation of the jaw bones. Option D is incorrect because the dislocation can actually lead to difficulty in chewing due to the misalignment of the jaw. Therefore, option A is the correct answer as it is the most likely outcome of bilateral dislocated fractures of the mandibular condyles.
