Dent, 46, has guided the IceHogs to back-to-back Calder Cup Playoff appearances after missing the postseason in his first three seasons.
He served as an assistant coach for five seasons under Mike Haviland and Bill Peters before being he was promoted in 2011. During his time as an assistant with the Blackhawks organization, his teams have compiled a regular season record of 216-145-17-22 and qualified for the Calder Cup playoffs in four of the five seasons.
In all, he has served as an IceHogs coach for nine seasons and is the franchise's all-time leader in games coached at 378.
One of the first tasks Dent will have at the end of the season will be replacing assistant Mike Osiecki, who is leaving for his alma mater, Wisconsin, to serve in the same role.
