Chistov showed a burst of speed, cutting around Komisarek and slipping a shot between Huet's pads for his second of the season, making it 4-2.
The Canadiens, unbeaten in regulation since a 6-5 loss to the Bruins in Montreal on Dec. 4, erased a two-goal deficit midway through the second period.
Montreal cut it to 2-1 when Komisarek scored on a deflected shot from the left point with 3:54 left in the opening period. Ryder's short-handed score tied it 12:08 into the second.
After Alexei Kovalev was given minor penalties for tripping and unsportsmanlike conduct, Saku Koivu took a loose puck and rushed out of the zone, setting up a 2-on-1 break. He slipped a cross-ice pass to Ryder, who fired a shot past a diving Thomas.
The Bruins grabbed a 1-0 lead on Chara's goal 8:29 into the first period when his slap shot from the left point appeared to take a short hop past Huet. They made it 2-0 on Sturm's power-play goal 4:14 later when he one-timed Bergeron's pass from the right circle.
Thomas kept the game scoreless with a couple of splendid stops in the opening 4½ minutes. He robbed Mike Johnson with a sliding glove stop and made a diving glove save on Sergei Samsonov.
Notes: Bergeron extended his consecutive point streak to eight games, one short of his career best set earlier this season. ... Bruins winger P.J. Axelsson missed his 10th straight game with a left foot injury. ... Montreal plays its next three games away from the Bell Centre. ... The Canadiens had won the prior two meetings against the Bruins after losing the teams' first of the season. ... It was a lively crowd, filled with many Montreal fans that could be heard chanting 'Let's Go Habs!' a number of times.
