Sinus membrane elevation without bone graft through crestal approach and simultaneous implant placement
By: Dong-Woo Kang, Young-Kyun Kim
Purpose
This study aims to evaluate the aspects of healing around the implants placed with sinus floor elevation without bone grafts through crestal approach.
Materials & Methods
Subjects and Outcomes of the study
Period : May 2014 to Dec 2014
Patients : A total of 7 patients
Implants : 9 TSIII short implants( SA 3, CA 6)
Outcome measures : the gray value in right after surgery, 3 months after surgery, prosthesis loading
Results
- The implant’s success rate without bone grafts for 16 months follow-up period was 89%.
- Although changing patterns are inconsistent, the same patient’s implants showed a similar Gray value changing pattern.
- Mucosal thickness and haziness seen in the immediate postoperative period were mostly reduced after 3 months.

| M2/54Y | #26 | 2.48 mm | 0.27 mm | 1.16 mm |
| M3/37Y | #16 | 3.04 mm | 0.51 mm | 1.02 mm |
| M4/54Y | #15 | 5.70 mm | 0.54 mm | 2.14 mm |
| M4/54Y | #16 | 4.05 mm | 0.88 mm | 3.64 mm |
| Average | 3.66 mm | 0.71 mm | 2.31 mm |
Conclusion
Sinus membrane elevation and simultaneous implant placement without bone grafts through crestal approach technique seem to be good results.
