Marcus Camby finished with 14 and 10 rebounds -- his 23rd double-double this season -- and Nene contributed 12 points.
The Nuggets have won 14 of the last 15 games at home against the Blazers.
LaMarcus Aldridge finished with 24 points and a career-high 17 rebounds, only his third double-double of the season. Zach Randolph added 26 points and Brandon Roy had 16. Jarrett Jack finished with 13 points and nine assists.
The Nuggets held on to their late lead this time. When Portland played in Denver on Feb. 2, the Blazers came back from a seven-point deficit in the final 1:35 before losing 114-107 in overtime. Former Blazer Steve Blake took over in overtime, scoring eight of the Nuggets' 17 points.
Blake also had a big basket on Tuesday night. After Aldridge hit a shot to trim Denver's lead to 99-93, Blake nailed a jumper with 1:24 remaining to put away the game.
After trailing by as many as 18 in the first half, Portland made a game of it, outscoring Denver 32-18 late in the third quarter. The Blazers pulled to 75-71 on a 3-pointer by Ime Udoka with 15 seconds left in the period.
However, Denver built the lead back up to seven on a free throw by Iverson and Nene's putback of a missed free throw by Iverson at the buzzer.
J.R. Smith returned to the court after missing eight of the last nine games due to arthroscopic surgery on his left knee. Smith played almost 15 minutes and hit just one 3-pointer.
