  3. 3.  Inlay type ridge augmentation  Direct and indirect sinus lift procedure
  4. 4.  Tatum 1986---modified caldwell luc approach
  5. 5.  U shaped osteotomy of the maxillary sinus  Swinging the partially freed-up bone segment cranialy into the maxillary sinus.  Created space is filled with bone graft  Implant is palced after 6 months

  7. 7. Indirect sinus lift procedure  less invasive  shorter healing and waiting period  <10mm >7mm  Increasing vertical height of the bone upto 4mm  sinus is approached from crest of the alveolar ridge and an osteotome is used.
