Evaluation of the Effect of Maxıllary Sinus Augmentatıon on the Maxillary Sınus Volume and Sinus Physiology: A Cone-Beam Computed Tomography Follow-Up
Üst veriTüm öğe kaydını göster
Sinus lifting procedure is a form of preprosthetic surgery for increasing the quantity of bone in the posterior maxilla. Although not many patients develop maxillary sinus pathology-related complaints after sinus floor elevation surgery, this procedure carries the inherent risk of compromising sinus physiology. There is the risk of miscalculating the amount of available bone in the posterior maxilla for implant placement by using two-dimensional panoramic views. CBCT provides much more accurate measurements of the available bone volume. The overall aim of the present thesis were to evaluate three-dimensionally the augmented bone volume and total volume of the maxillary sinus, correlation between the thickness of the Schneiderian membrane and crestal gingival thickness, following sinus lift procedures. In this study all included 22 patients were successful two stage sinus elevation surgeries and without complications. All patients were preoperatively and postoperatively analyzed by CBCT. The average percentage of the grafted part was 14.87 % through manual measurements and 14.66 % through automatically measurements. Safe volume after sinus grafting means not to interfere with the osteomeatal unit that hazardous to sinus physiology. No correlation weref found between the thickness of the Schneiderian membrane and crestal gingival thickness.
