Nineteen of Medvedev's 21 victories have been won on hardcourt
A revitalized the Russian player secured his maiden title for nearly 30 months with a win over Frenchman Moutet in the tournament title decider.
The athlete, a ex- number one, has experienced a torrid year, winning just a single victory at the big events and undergoing a meltdown at the US Open.
Medvedev's varied form on the professional circuit - and difficulties with his serve in particular - led to him dropping out of the top ten and ultimately separating with former coach Cervara.
Currently training with Johansson and Goetzke, Medvedev has gradually advanced in the past month - culminating in a tightly fought three-set victory over opponent Moutet.
This represents his first trophy after the Italian tournament and first on a hardcourt from that period of the previous year.
The win also means the Russian has won twenty-one victories at 21 different events.
"It's the first time I am participating in a competition with my both daughters at once, so to get a trophy is particularly special," stated tennis professional Medvedev.
"This championship is in honour of my second daughter Victoria, because the maiden victory I won when my older daughter her name was delivered was for her."
Medvedev, the former major winner, had been defeated in his last six title deciders, featuring in the German tournament in the past months.
His counter-punching strategy and frequent reactions on the playing surface had caused commentators to doubt if his capacity to perform at the top level was concluded.
But the player has implemented adjustments in the last few weeks, attempting to approach the net and compete aggressively, reinforced by an better serving game.
He recovered from a disadvantage in the initial set against the difficult Frenchman, securing four of the final five games to go ahead.
The competitors traded breaks in the second set before Moutet, bidding for his first professional title, seized the initiative to create a third set.
Moutet saved 4 early chances in a competitive final set before Medvedev won the break to that score to secure the win.
Suitably, he secured victory with a point at the front of the court, with his opponent incapable to handle a return after over two and a half hours.
