Lateral sinus lift or verticle sinus lift?
Tooth #3 was extracted 12 months ago and a bone graft was placed. Patient is ready to do an implant in the area. There is less than 5 mm of vertical height of bone in the area. Would bicortical fixation be enough with an internal violated antrum approach with an osteotome verticle sinus lift or would it be more stable to do a lateral sinus lift? Please view cbct.
