Sinus Lift

  1. 1. Majd Hasanin
  2. 2. There are two main approaches for lifting the maxillary sinus: Direct Indirect(Cold Well Luk) (Osteotome) Majd Hasanin
  3. 3.  Augmentation can be achieved either by placing material in direct contact with the membrane or by creating a new cavity using a sinus partitioning technique, which is recommended for the creation of a stable site, augmented with autologous bone harvested from an extra- or intraoral site. Majd Hasanin
  4. 4. Majd Hasanin
  5. 5. -- Direct Sinus lift procedure Abrahams, J. J. et al. Am. J. Roentgenol. 2000;174:1289-1292A, Drawing shows that, after incision, soft tissue in anterior maxilla has been reflected back toexpose overlying maxillary sinus (arrowheads). Note osteotomy (arrows) in bone. Majd Hasanin Copyright © 2006 by the American Roentgen Ray Society
  6. 6. --Sinus lift procedure Abrahams, J. J. et al. Am. J. Roentgenol. 2000;174:1289-1292B, Drawing shows cross-sectional (lateral) view of maxillary sinus. Note that bone flap created byosteotomy has been pushed inward with maxillary sinus membrane, Majd Hasanin Copyright © 2006 by the American Roentgen Ray Society
  7. 7. --Sinus lift procedure Abrahams, J. J. et al. Am. J. Roentgenol. 2000;174:1289-1292C, Drawing shows osteotomy and sinus membrane displaced inward and space packed with bone graft. Majd HasaninCopyright © 2006 by the American Roentgen Ray Society
  8. 8. --Sinus lift procedure Abrahams, J. J. et al. Am. J. Roentgenol. 2000;174:1289-1292D, Drawing shows cross-sectional view of maxillary sinus. Bone graft fills space created by inwarddisplacement of osteotomy and sinus membrane. Majd Hasanin Copyright © 2006 by the American Roentgen Ray Society
  9. 9.  It is clear. Easy Access. Loading of the implant can be immediate. More efficient work is done. Majd Hasanin
  10. 10.  More Pain. More post-operative discomfort. Time Consuming. Needs highly efficient practitioner. More susceptible for infection. Majd Hasanin
  11. 11. Majd Hasanin
  12. 12.  Invented by Summer in 1994 ;1. A crestal incision is made, and the crestal ridge is exposed.2. A sharp osteotome is used to "chisel" a rectangle in the crestal ridge of the maxilla, then a sinus-lift osteotome is used like a mallet to fracture the bone Majd Hasanin
  13. 13. 3. Punch a hole through where the rectangle was created into the sinus floor. The sinus is then raised with bone grafting material and implants are placed. Majd Hasanin
  14. 14. Majd Hasanin
  15. 15. › Minimally invasive surgical procedure.› The osteotomy is minimal being 1-3 mm deep and wide.› Minimal instrumentation with closed graft deliver permits a sterile technique.› Simplicity of the procedure requires less time and expertise. Majd Hasanin
  16. 16. › Immediate implant loading is recommended after 3 months.› Blind procedure (the sinus isn’t exposed).› More chance of errors to occur. Majd Hasanin
