  4. 4. sinus lined by- respiratory epi. Namely pseudostratified, ciliated, columnar epi www.indiandentalacademy.com
  5. 5. www.indiandentalacademy.com
  6. 6. The widespread use of implants for the replacement of missing teeth has led to the use of more sophisticated surgical techniques in sites that previously were considered as contraindication to implant therapy www.indiandentalacademy.com
  7. 7. The posterior region of the edentulous maxilla frequently presents insufficient bone for rehabilitation by means of endosseous implants. Maxillary sinus lifting using a bone graft was first introduced by Boyne and James and Tatum. This technique has been used to permit the. placement of endosseous implants in edentulous or excessively pneumatized maxillae www.indiandentalacademy.com
  8. 8. . Although the lateral maxillary window approach, also known as the CaldwelllLuc approach, may yield very successful clinical results for sinus grafting, this method has many shortcommings. www.indiandentalacademy.com
  9. 9. Limitations of the lateral maxillary approach include  sinus membrane perforation (10% to 35%),  bleeding,  infection,  infraobital nerve laceration,  and the need for extensive surgical expertise. www.indiandentalacademy.com
  10. 10. Postoperative discomfort including  swelling,  discoloration,  disability,  hematoma,  and pain occur very often www.indiandentalacademy.com
  11. 11. The other technique currently in practice is a limited sinus elevation using an osteotome, which yields an average bone height According to standard protocol, the osteotome technique can only be used when the ridge height is more than 5 mm and implants are placed simultaneously with the elevation of the sinus floor. Moreover, this procedure can also be complicated by membrane perforation and tear. www.indiandentalacademy.com
  12. 12. Kfir etal reported a minimally invasive technique for sinus membrane balloon elevation followed by implant placement. This procedure had satisfactory bone augmentation results (usually> 10 mm) and good implant durability. www.indiandentalacademy.com
  13. 13. For patients, this procedure eliminates the complications,  discomfort,  disfiguration,  and disability associated with the traditional lateral window approach www.indiandentalacademy.com
  14. 14. Local anaesthesia (via infiltration of the posterior superior alveolar nerve and greater palatine nerve) was executed using articaine hydrochloride . An alveolar horizontal full-thickness flap was performed. No vertical releasing incision was employed and the flap was reflected not exceeding the alveolar ridge www.indiandentalacademy.com
  15. 15. www.indiandentalacademy.com
  16. 16. Implant site preparation employing a 2-mm- diameter pilot drill, followed by one with a diameter of 2.8 mm, reached about 1 mm short of the sinus floor. Then, the sinus floor was gently elevated using osteotomes www.indiandentalacademy.com
  17. 17. After examining the integrity of the sinus membrane by way of the Valsalva maneuver, the dedicated inflatable balloon (Hager & Meisinger) was anchored and the balloon was slowly inflated with gentle inflating pressure using an inflator syringe filled with 0.90% normal saline. www.indiandentalacademy.com
  18. 18. Once the desired elevation (usually > 10 mm) was obtained, the balloon was deflated and removed. A second test of membrane integrity was completed in the same manner as previously mentioned. www.indiandentalacademy.com
  19. 19. www.indiandentalacademy.com
  20. 20. A mix of autologous platelet-rich fibrin (obtained by centrifugation of 20 mL of patients' blood divided into two test tubes and spun for 10 minutes at 1,600 RPM,) and Bio-Oss particles was filled under the elevated sinus membrane www.indiandentalacademy.com
  21. 21. www.indiandentalacademy.com
  22. 22. After bone transplantation, implants (CAM LOG Biotechnologies) ranging from 3.8 to 5.0 mm in diameter were placed and primary closure was performed with 4-0 absorbable sutures Prosthetic rehabilitation was delivered 4 weeks after implant exposure. www.indiandentalacademy.com
  23. 23. Patients were discharged with a single, 600- mg dose of Ibuprofen for the treatment of pain and Velosef 0.5 g tid for 7 days for prophylaxis www.indiandentalacademy.com
  24. 24. Pre- and postoperative panoramic films or CTs (optional) were taken for every case to measure and compare the results of the sinus membrane lift procedure using a water balloon. Periapical films were employed to observe the marginal bone resorption and Osseo- integration after permanent prostheses delivery www.indiandentalacademy.com
