I placed 2 implants in the maxillary right posterior quadrant using an indirect sinus lift without bone grafts. The implant in 16 is 3.5×11.5mm and the implant in 17 is 5x10mm. The buccolingual bone width was sufficient. I am concerned about 2 potential problems:
- Do you consider the implant in 17 site too close to tooth 18?
- The distance between the implants is considerable.
Can you recommend options for prosthetic rehabilitation with the greatest chance for long term success?
