This study is aiming to evaluate primary stability of implant in closed sinus lifting cases by Densah bur in compared to Osteotome in partially edentulous patients hoping that densah bur can lift the sinus membrane and improve primary stability of implant.
The osteotome technique is effective in certain cases, but the most sensitive aspect is the tapping force, which should be sufficient enough to infracture the sinus floor cortical bone but restrained enough to prevent the osteotome tip from traumatizing the Schneiderian membrane.
Several surgical techniques have been proposed to minimize the sinus membrane perforation rate by using a piezosurgical device, balloon, hydrostatic pressure.
The success of therapy in posterior maxilla is not only dependent on the success of the sinus elevation but also the primary stability of the implant that allow bone apposition on the implant surface without any micromovement for osseeointegration.
Later, densah burs are introduced as another treatment option for internal transalveolar approach of sinus floor elevation with improving primary stability of implant by osseodensification.
As treatment options of edentulous maxillary today may include dental implants, the practitioner must be familiar with various sinus lift surgical techniques in order to choose an ideal treatment option for the patient.
