Can I salvage dvd+r with "incomplete last session" ?

Hello

Back in August, I've burned with k3b and a pioneer dvdr109 some prodye
DVD that I cannot read anymore (although I did verify them with k3b).

Anyway,  dvd+rw-mediainfo reports:

What does this "incomplete status" means for the last session and
track state ?

Is there any way to "finish" the session to get a readable dvd ?
(to salvage my data)

Cheers
