Wilson has joined the Cherries from Stoke for £1.5 million.
Wilson has joined the Cherries from Stoke City for a fee in the region of £1.5m, signing a two-year contract after making 177 appearances for the Potters.
The Republic of Ireland international has worked under Howe before, previously turning out for Bournemouth across two separate loan spells, and was believed to have been a long term target of Howe's.
Now that he has got his man Howe has expressed his delight, but has not guaranteed Wilson will command a place in his starting 11 immediately.

“I have worked with Marc a couple of times, once as a player at Portsmouth where we played together briefly," said Howe.
"Then, he came here on loan when I was part of the coaching team.
“He is a very talented player, a versatile performer and he adds numbers and experience to our backline.

“It is a minimal fee by today’s standards so we are hopeful he will add what we want to the squad. He has been in the Premier League for a number of years and that can only help us.
“He still has to force his way in and we have some talented players here. We are thin on the ground in terms of defensive options so it is certainly welcome. He will add competition for places in that area.”
Wilson is Bournemouth's seventh summer signing, and the defender arrives with a wealth of experience in the Premier League.
A versatile player who can also operate in midfield, the former Portsmouth will bolster the depth in Bournemouth's squad and provide options across the park, adding to the quality Howe has already brought in this summer.
