The situation is as you described Bryan, there is a small portion of the bone graft not being covered with soft tissue on the palate.

I cant really tell if it was initially covered since I realised of.it after the 4th day.

The surgeon saw me several times. The first time at the 4th day and he saw there was a fibrin clot right were I have the exposed bone (i dont have fibrin.any longer).

He just told me to have great higiene over that area and now he is on vacations, he doesnt seem to worry much about the exposure. In one month he will make a flap and take out the dead bone, tho Im worried if it gets infected.
