The Polish team finished runner-up, behind hosts Great Britain, at the championship, which was held in Nottingham from April 29 to May 5.
The Polish men's national ice hockey team won four matches in the tournament, defeating Lithuania 7-0, Italy 4-2, South Korea 7-0, and Romania 6-2, according to the Polish Ice Hockey Federation (PZHL).
The Poles, coached by Slovak Robert Kalaber, lost to Great Britain 4-5 in extra time, the Polish Ice Hockey Federation said.
The Polish team went into the tournament ranked 22nd in the world by the International Ice Hockey Federation (IIHF).
Poland are returning to the elite pool after a hiatus of more than two decades, news outlets reported.
"It's really amazing," said Poland captain Krystian Dziubiński. "I've been waiting for Poland to go back to the top division since I was a kid."
Forward Alan Łyszczarczyk said: "It's awesome. I've been working for this my whole life. We all have. Now the dream has come true for everyone."
Poland will face off against the likes of Canada, the United States, Sweden and Finland at next year’s IIHF Ice Hockey World Championship in the Czech Republic.
