Can you advise me after failed bone graft, as I don’t want to return to dentist who nearly killed me?

Q. In Nov 09 I had all my top teeth pulled after having a 9 unit bridge fail. The teeth extracted were 6,7,8,11,& 12, Implants were placed in 11 & 12. Bone graft was done on total upper jaw. I have a bleeding disorder called Von Willibrands. I ended up in the hospital that night and had to stay to get a special drip for my bleeding. I bleed so much that I threw up a lot. I was real concerned about damage all of this could have had done to my bone graft. I had a front missing that had caused a lot of bone loss. The dentures made had the impress were the bone loss was. So this caused the new bone to be pushed in. It also caused my stitches to tear louse to soon. I choose not to go back to this surgeon because he could have killed me by not doing his job with my Haematologist as he was given number and was suppose to do. He said since I had a few pulled before he thought it would be ok not to, since they tried once and didn\’t get a call back. My concerns or now before I have new teeth made is that i have a lot of sensitivity by implants and a lot of bone loss in 7,8,9,and 10. and a dip in the center of my mouth where bone was pushed. I basicly have a lot of uncomfort. I feel like somethings not right. the surgeon I saw to put abundment in says it doesn\’t have to be perfect. I dont want to go any further unless things or right. I feel that i need more bone put in that i loss from bleeding, throwing up and have dentures that had not been corrected for bone implant. Could you give me some advice. Thank you. Wish I could send pictures.,
