1. An implant for therapeutically separating bones of a joint, the implant comprising:
a first end plate having a bone engaging surface;
a second end plate having a bone engaging surface and disposed to face the first end plate;
an actuator positioned between the first and second end plates;
a pivot member positioned between the first end plate and the actuator to allow the first end plate to slide and pivot against the actuator;
a drive assembly having a actuator screw coupled to the actuator and configured to translate the actuator to cause the first end plate to vertically rise relative to the second end plate, pivoting of the pivot member allowing an angle between the first and second end plates to change.
