Louie Spence, Katarina Witt and Robin Cousins will make up the panel for the ITV skating show's next run, which begins in January.
The news follows Friday's confirmation that former judges Jason Gardiner and Emma Bunton have left the series.
Karen Barber will return in her role as head coach.
Choreographer Spence has worked with Kylie Minogue, Robbie Williams and Mariah Carey, and is best known for appearing on Sky1's Pineapple Dance Studios and Show Business.
He said: "I'm looking forward to being part of such a challenging and spectacular show and can't wait to give my encouragement and critique on the contestants' dance and performance on the ice."
Figure skating champion Witt won gold medals at the Sarajevo 1984 and Calgary 1988 Olympic Games, and holds the record for most consecutive European titles alongside Sonja Henie.
"I can't wait to join the Dancing on Ice judging panel," Witt added. "As well as offering support and constructive advice to this year's celebrity skaters I'm also looking forward to working alongside my close friends Torvill and Dean."
ITV Controller of Entertainment Layla Smith said: "We are thrilled to welcome Louie and Katarina to the new Dancing on Ice panel. The pair have a wealth of experience which they will be bringing to the new series. Their unique flare and passion for their professions will doubtless make for some interesting debates.
"We'd like to thank Emma Bunton and Jason Gardiner for their valued contribution during previous series and wish them both all the best with their future projects."
Barber rejoins the judging panel after serving as the celebrities' mentor on the last series of the show, while head judge Cousins retains his position in the lineup, which he has held since the programme began.
Christine Bleakley recently replaced Holly Willoughby as next year's host alongside Phillip Schofield.
