Nineteen of the Russian's 21 titles have been achieved on hard surfaces
A revitalized the Russian player claimed his maiden trophy for 882 days with a win over Frenchman Moutet in the tournament championship match.
Medvedev, a former world number one, has endured a torrid period, managing just one win at the Grand Slams and undergoing a meltdown at the New York tournament.
The player's varied form on the ATP Tour - and struggles with his service game in especial - led to him exiting of the top ten and eventually separating with long-time trainer Cervara.
Presently working with Johansson and his other coach, the tennis star has steadily advanced in the last few weeks - peaking in a hard-fought 7-5 4-6 6-3 triumph over challenger Corentin Moutet.
This represents Medvedev's initial championship since the Italian tournament and first on a hard surface after spring of 2023.
The win also means Medvedev has secured 21 titles at twenty-one distinct tournaments.
"It's the first time I'm at a competition with my both daughters at once, so to win a trophy is especially meaningful," said world number 14 the champion.
"This victory is in tribute of my child Victoria, because the maiden victory I got when my older daughter her name was delivered was for her."
The tennis star, the former major winner, had lost his past six title deciders, featuring in the German tournament in the past months.
Medvedev's counter-punching strategy and regular reactions on the tennis court had prompted commentators to wonder if his ability to compete at the elite level was over.
But the player has altered his approach in the last few weeks, striving to advance forward and play positively, supported by an improved serve.
Medvedev recovered from a deficit in the opening set against the tricky Frenchman, winning four of the final five points to gain the advantage.
The pair exchanged break points in the following set before Moutet, striving for his maiden ATP Tour title, took control to push for a final set.
The opponent rescued four initial opportunities in a tight final set before the Russian secured a break to fifteen to close out the victory.
Suitably, he clinched the win with a rally at the net area, with his opponent unable to control a shot after over two and a half hours.
