I am a 60 year old male patient. I had a bone graft on the upper right side of the mouth, which resulted in uneven bone formation. Within 6 months of the bone graft, I had one implant placed in the middle where bone height was maximum. 4 months after the first implant was placed, I had two smaller implants placed, as seen in the image, on the sides of the first implant. Additional bone graft material was inserted to the right side where there is a bigger void, and a sinus lift was performed at the site of the implant to the left. All implants are Nobel Active implants.
What do you think of the spacing between the implants? Also, it seems like the new implants are very close to the voids on both sides. Does this increase the possibility of implant failure? What can be done to ensure success as this case proceeds? Any help would be highly appreciated.
