Implant position: opinion?


I just did a case today. 2 extractions(1.5 and 1.7), a cystectomy in area of 1.7. I placed 2 implants in position of 1.4 and 1.6 (with sinus lift lateral approach). Clinically, I measured the distance implant-teeth, implant -implant. The distance between implant 1.4 and 1.3 was more then 2.3 mm (I tried to place it more to the alveolar of 1.5 ). After 2 Rx it shows that it is in contact with 1.3. (I know that to be sure I need to do a CBCT).Can you give me an honest opinion, and advice on this case? Thanks in advance.
