Chara, speaking to reporters at the Bruins' end-of-season availability Friday, said his jaw was being held together by "two plates, some wires and screws" for the last three games of the Final, won by the Blues on Wednesday.
"It's an amazing job on this," Chara said. "They were able to put [it] together quick -- 36 hours from the end of Game 4 to Game 5.
"Just being hit by a puck or blocking shots, there's nothing you can do about that. You play the game to put your body out there."
The 42-year-old Chara said the expected recovery time is 5-6 weeks.
He also is planning to have an MRI for the lower-body injury that kept him out of Game 4 of the Eastern Conference finals against the Carolina Hurricanes.
"That's who he is," Bruins forward Jake DeBrusk said. "It was just one of those things where you want to rally around him and help him out."
Chara thanked the Boston fans for their support, citing their "overwhelming cheers and applause" before as he stood on the ice before Game 5.

The Bruins reported to their workout facility Friday for their wrapup media availability.
Forward Brad Marchand said he was dealing with issues in his groin and abdomen, and also a sprained hand that he exacerbated during the intrasquad scrimmage scheduled to keep the team fresh during a long layoff after sweeping the Hurricanes.
But mostly, the Bruins are hurting after getting to the last possible game of the season and falling short.
"You start thinking about 'what if,'" said Marchand, who was a member of the team that won it all in 2011 and returned to the Cup Final two years later. "When you get that taste, when you get that close, it just makes you want it that much more. That makes it that much harder to lose. When you know how good it is, getting that taste is a weapon.
"Nobody's going to say anything that's going to make you feel any better. Even if we win the Cup next year, that isn't going to make this go away."
