Jesper Mattson and Niklas Kronwall both scored a goal and an assist, while Johan Holmqvist recorded his second shutout of the event to help the Tre Kronor to the title.
The teams began their final match cautiously trying to find a way to expose their rival’s defensive frailties without taking unnecessary risks.
However, the Swedes looked more focused and played with greater accuracy to clinch a comfortable 2-0 lead before the first intermission as their forwards Mattson and Fredrik Emvall scored one apiece within just 37 seconds.
Detroit Red Wings defender Kronwall netted Sweden’s third 4:07 into the second period, while Jorgen Jonsson made it 4-0 on a two-man powerplay with 2:59 remaining before the second break.
In the third period, the Swedes eased up the pressure but their domination was never in doubt as they easily stifled the Czechs’ attacking efforts grabbed their first world crown since 1998.
With that win, the Swedes also grabbed the lead in their head-to-head record with the Czechs as the opponents were both with four wins at the world championships before their final clash here.
Earlier on Sunday, Finland won the bronze medal, clinching their first podium place since 2001, by thrashing Canada 5-0.
“Bronze medal games are not easy at all,” Finland manager Erkka Westerlund said after the match. “The mental preparations after losing the semi-final are very difficult.
“I’m proud of my team. They’ve prepared very well for tonight and they really were a team of lions on the ice. It’s always tough to beat Canada, the motherland of hockey.”
Antti Miettinen scored a goal and an assist, while Fredrik Norrena produced 37 saves and recorded his third shutout of the event to help Finland gain revenge for a 4-2 defeat in the qualifying round of the event.
However, Canada still have an impressive head-to-head record against Finland at the world championships with 33 wins to just seven defeats and two draws.
Tomi Kallio put Finland in the lead 4:06 into the match on a powerplay, while Florida Panthers’ forward Oli Jokinen increased Finland’s advantage 5:20 into the second on a two-man powerplay.
Riku Hahl added his goal with 3:42 remaining before the second intermission before Dallas Stars’ strikers Miettinen and Jussi Jokinen both scored in the third to complete whitewashing of Canada.
“I would like to congratulate Finland. They deserved their win, they were better than us,” Canada’s coach Marc Habscheid said. “Yesterday we suffered a really heart-breaking loss but our guys came out hard and we started well.
“My team is very young. A bigger part of it is the future of Canadian hockey and you can see our future is great.”
