This 59 year old male with no significant personal or medical history who presented with bilateral edentulous maxillary posterior segments. I have treatment planned him for implant placements. I have enclosed the CBCT scan. My question is if it is advisable to proceed with bilateral sinus lifts to create a more favorable environment for the implants with bone augmentation. The CBCT scans show deficient bone bilaterally in range of 3-5 mm and thickened sinus membrane (5-6 mm in 1st quadrant and up to 16 mm in 2nd quadrant in first molar region). Clinically no signs of maxillary sinusitis are evident. How do you recommend that I should proceed with this case? Do you advise going ahead with the sinus lifts?
