Carmelo Anthony scored 38 points and grabbed 12 rebounds to lead the Nuggets.
John Salmons scored a season-high 33 points, but coach Scott Skiles said they got little else offensively.
The Bucks lost for the 8th time in the last 10 games and they continue to be the worst-shooting and lowest-scoring team in the league.
The Bucks are off for five days now. The first game after the all-star break is next Tuesday at home against Minnesota.
