I am considering immediate placement of a fixture replacing tooth # 19. I have had 20+ years placing implants as a GP, but this will be my first immediate placement. I am considering using a 5.0 Nobel Active, or a 7.0 Keystone. I plan on using the bone between the roots as a starting point, and grafting the remaining voids with demineralized bone matrix paste and covering with a resorbable membrane. I am concerned about primary closure without raising a flap. I am considering lowering the crestal height to allow the soft tissue to fully close. I would appreciate any insight on this proposed treatment.
