Nineteen of Medvedev's 21 championships have been earned on hard courts
A resurgent Medvedev won his maiden title for nearly 30 months with success over opponent Moutet in the tournament title decider.
The Russian, a former number one, has experienced a difficult year, managing just one win at the big events and suffering a setback at the American major.
The player's unpredictability on the ATP Tour - and issues with his service game in specific - caused him falling of the world's top 10 and finally separating with long-time mentor Cervara.
Now training with Johansson and Rohan Goetzke, the tennis star has steadily improved in the recent weeks - culminating in a closely contested three-set victory over challenger Corentin Moutet.
It is Medvedev's maiden championship since the Rome competition and initial on a hard surface after March of the previous year.
Victory also signifies he has secured twenty-one victories at twenty-one different events.
"It's the first time I'm at a tournament with my both daughters simultaneously, so to win a trophy is especially meaningful," commented world number 14 Medvedev.
"This title is in honour of my child her name, because the first title I achieved when my first daughter her name was born was for her."
Medvedev, the past champion, had failed in his past six championship matches, comprising in Halle in the past months.
Medvedev's retrieving play style and frequent outbursts on the tennis court had prompted some to question if his ability to perform at the elite level was concluded.
But the 29-year-old has altered his approach in the last few weeks, striving to come to the net and perform aggressively, backed up by an better serving game.
The champion fought back from a disadvantage in the opening set against the challenging opponent, securing 4 of the concluding five games to gain the advantage.
The competitors traded breaks in the second set before the challenger, attempting for his maiden tour victory, took control to create a decider.
The opponent rescued four initial chances in a close third set before Medvedev won the break to 15 to secure the win.
Appropriately, he clinched the win with a shot at the net, with his opponent unable to manage a return after over two and a half hours.
