No results posted yet for this study

Summary

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.

Conditions

  • Sinus Pneumatization

Interventions

OTHER

closed sinus lifting by Osteotome

* Local anesthesia will be injected intra-orally * A full thickness flap will be elevated * A pilot drill will be used to start the osteotomy preparation, which should be ended 1mm short of sinus floor. * The widening drills can be sequentially used to widen the osteotomy site to the same level * An osteotome of diameter a little less than the planned implant body, will be inserted in the prepared osteotomy site and gently tapped to reach the same level. * The osteotome will be tapped gently to fracture up the sinus floor. * Xenograft will be added to the osteotomy as the grafting material. * Once the desired height of sinus elevation will be gained and grafted, the implant fixture will be inserted. * Smart peg will be placed on implant and Ostell will be used to record ISQ. * Healing collar will be placed on implant. * Suturing the flab around healing collar.

closed sinus lifting by Densah bur

* Local anesthesia will be injected intra-orally * A full thickness flap will be elevated * A pilot drill will be used to start the osteotomy , which should be ended 1mm short of sinus floor. * Change the drill motor to reverse- densifying Mode * with the densah bur (2.5mm) until 1 mm short of the sinus floor. * Use the next wider Densah Bur (3.0) in densifying-mode until feeling the haptic feedback of the bur reaching the dense sinus floor, modulate pressure with a gentle pumping motion to advance past the sinus floor in 1 mm increments. * densah burs (3.5mm) advance in the osteotomy. * Xenograft will be added to the osteotomy . * Once the desired height of sinus elevation will be gained and grafted, the implant fixture will be inserted. * Smart peg will be placed on implant and Ostell will be used to record ISQ. * Healing collar will be placed on implant. * Suturing the flab around healing collar.
