Many years ago I lost my upper rt 4 and 6 teeth. Upper rt 5 had had a couple of unsuccessful apesectomies but until recently anchored a bridge. Upper 1 and 2 are post crowns and upper three achored a bridge over missing 4 to no 5. Upper 5 started to produce an abscess which kept appearing on my gum and bursting and as a result of this I decided I would have an assessment for implant(s). On further x-raying my mouth it was found that upper 1 and 2 had shadows which in the future could prsent problems and in fact upper 2 failed and has just this week had to be removed resulting in my now wearing a temporary denture. Upper 5 was removed in January. I have consulted with an implant surgeon and he is suggesting the removal of remaining 1 and 3 (although 3 is a perfecting healthy tooth) and inserting three implants to carry a bridge. When 5 was removed and now 3 I noted that the sockets have not been packed with synthetic bone (I have been advised that I do not require bone grafts.) Will these cavities not having this packing in any way minimise the effectiveness of my implants and would you have an opinion on removing 3 which is a healthy tooth. Appartently the removal of three will provide for a better aesthetic look as it is felt that two implants side by side results in loss of papilla. Any reassurance would be great!
