Extraction and crestal approach sinus lift vs extraction and delayed implant placement? Fremont, CA

Extraction and crestal approach sinus lift vs extraction and delayed implant placement?

Planning a case for implant placement. #14 and #13 [maxillary left first molar and second premolar; 26, 25] are unrestorable. Resorbed ridge height is about 8mm at #14 area. My plan is to extract 13 and 14, place 11.5mm length implant for #13 (more apically for stability) and 6.0 diameter x 10mm length implant for #14. I plan to perform crestal approach lift, and lift approximately 3-4mm. My comfort zone would be to place a longer implant in 14 area but concerned about possible tear trying to lift too much, therefore planning to make diameter wider. My other concern is obtaining primary closure and risk of failure if I cant close suture once done, and risks of extracting, lift and implant placement all at the same time instead of extraction and grafting, waiting 4 months then implant placement with sinus lift. Ive attached CBCT, slices of 13 and 14 as well as intra oral of area. Your input is appreciated.
