Davis' start helped the Magic shoot 46 percent (21 for 45) from the field in the first half on their way to building a 51-35 halftime advantage.
Indiana sprinted out to a 15-8 lead before a 32-8 run by the Magic gave them their largest lead of the half at 40-23.
Orlando spread the offensive wealth, getting a variety of shots inside and out. The Magic hit six 3-pointers and Davis and Vucevic combined for 19 first-half points.
Magic coach Jacque Vaughn acknowledged it would take some time to integrate Davis back into the rotation like he was before his injury. He also said he isn't worried about cutting into the groove Vucevic has found on the inside in Davis' absence.
Vaughn said having them both healthy now will give him extra options against bigger teams. He said Vucevic having to play without Davis recently has given Vucevic a lot more confidence.
"That's just the trust that I have in him and the fact that he could guard Hibbert and when Hibbert leaves the floor, I could stick him on David West," Vaughn said. "That's unbelievable conditioning by himself, drive that he has. ... He's continuing to improve and I'm extremely proud of him."
With four of their next five games at home, Davis said he hopes his team takes advantage of their surroundings.
"We've got to protect home court definitely," he said. "And to be home gives you a level of comfort. At the same time, we're not really trying to be comfortable. We're trying to win games. We're behind. We lost a lot of games. We've gotta go and kind of catch back up."
NOTES: Vucevic now leads Orlando with 20 double-doubles this season. ...
