Having racked up his second European Tour title of 2024 at the Flanders Darts Trophy earlier this month, Chisnall came out on top of the 128-player field at the Mattioli Arena to double his Players Championship title tally for the year.
Chisnall was at his free-flowing best en route to the final, producing averages of 108.72 and 107.19 in victories over Mervyn King and Madars Razma respectively.
"The final was a tough battle, it wasn't a good game but I'm just happy to get over the line," said Chisnall, whose £15,000 prize sees him regain his place as world number five.
"I think my game is up there with the best in the world at the moment; I'm playing really well and my confidence is high.
"Six months ago I was losing first and second round matches but then I started to battle and I've won some big titles.
"There are some big events coming up and I normally have a good end to the year; I just need to get my TV form going now.
"I'm looking forward to the World Grand Prix; I've been hitting my doubles well so it should be a good one for me."
Chisnall began the day with comfortable victories over Callan Rydz, Dylan Slevin and Jeffrey Sparidaans before coming back from 5-3 down to defeat Razma 6-5 in their last 16 tie.
The six-time TV event finalist then overcame King 6-2 in the quarter-finals and Stephen Burton 7-4 in the semi-finals to set up a showdown with Dobey.
A scrappy contest saw both players struggle to replicate the form shown in the previous rounds, with a four-leg mid-match winning streak from Chisnall proving pivotal.
Dobey's 7-2 semi-final win over Martin Schindler saw him hit a nine-dart finish in the opening leg of a scintillating display which saw him post his fifth ton-plus average of the tournament.
That was the second perfect leg of the day, following Adam Warner's nine-darter in his second round defeat to Jurjen van der Velde.
