Nineteen of Medvedev's 21 victories have been won on hardcourt
A comeback the Russian player secured his first championship for 882 days with victory over Frenchman Moutet in the tournament title decider.
The athlete, a ex- world number one, has had a torrid season, achieving just one win at the big events and undergoing a setback at the New York tournament.
Medvedev's varied form on the tennis tour - and difficulties with his serving in specific - led to him falling of the world's top 10 and eventually parting ways with former mentor his previous coach.
Now collaborating with Johansson and Goetzke, he has gradually improved in the last few weeks - peaking in a tightly fought 7-5 4-6 6-3 triumph over Frenchman Corentin Moutet.
This marks the player's initial title following the Rome competition and maiden on a hardcourt after that period of the previous year.
Victory also indicates he has secured 21 titles at 21 various tournaments.
"For the first time I am participating in a competition with my two daughters together, so to win a title is particularly special," said world number 14 Daniil Medvedev.
"This championship is in dedication of my child my daughter, because the initial championship I won when my first daughter her name was born was for her."
The athlete, the past champion, had lost his last six title deciders, including in the German tournament in the past months.
His defensive play style and recurring emotional displays on court had caused observers to doubt if his capacity to perform at the elite level was over.
However the 29-year-old has altered his approach in the last few weeks, making an effort to approach the net and perform aggressively, supported by an better serving game.
The champion fought back from a break down in the initial set against the challenging opponent, winning four of the concluding five points to go ahead.
The pair swapped break points in the middle set before the challenger, striving for his first professional victory, gained dominance to create a decider.
The opponent defended 4 early-game break points in a competitive final set before the champion secured a break to that score to secure the win.
Suitably, Medvedev clinched the title with a point at the net, with the Frenchman failing to manage a return after a lengthy match.
