Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present study is a parallel single-blinded randomized controlled clinical trial.

The study will be conducted after being reviewed and approved by the Faculty of Dentistry, AinShams University Research Ethics Committee (FDASU-REC).

The study population will be randomly allocated into two groups of the same size:

Group 1: Osseodensifiction sinus lift will be performed using sticky bone as a graft material.

Group 2: Piezoelectric Internal Sinus Elevation (PISE) will be performed using sticky bone as a graft material.

The aim of the present study is to evaluate the effectiveness and clinical results of osseodensification in comparison to Piezoelectric Internal Sinus Elevation (PISE) Technique in Delayed Implant Placement.

osseodensifiction internal sinus lift / sticky bone graft material

Osseodensifiction compacts bone and simultaneously autografts it into the osteotomy walls and apex instead of removing it. The use of a Densah® drill bit at high speed counterclockwise, without a cutting edge and with a steady irrigation causes the formation of a layer of strong dense bone along the walls of the base of the osteotomy preparation.

Group Type EXPERIMENTAL

osseodensifiction internal sinus lift / sticky bone graft material

Intervention Type PROCEDURE

The osteotomy for the osseodensification internal sinus lift begins with a twist drill advanced at 800 rpm with saline irrigation to within 1-2 mm from the sinus floor. Next, a series of osteotomy drills are used in the same fashion at 800 rpm to widen the osteotomy. The final osteotomy drill is advanced with gentle pressure at 100 rpm counterclockwise without irrigation until a bouncing sensation occurs "haptic feedback" at this point infracture of the sinus has taken place. After infracture, injection of the graft material into the osteotomy site will occur. The final osteotomy drill is used to guide the graft apically. This process is repeated in an incremental fashion to lift the membrane. Once enough space has been created below the antral membrane, implant insertion will occur then suturing.

piezoelectric internal sinus lift / sticky bone graft material

The piezoelectric surgical sets comprise various inserts from osteotomies to diamond-cutting inserts. The hydropneumatics pressure of the saline solution irrigation is subjected to the piezoelectric cavitation pushing the Schneiderian membrane upwards resulting in its' detachment and floating

Group Type ACTIVE_COMPARATOR

piezoelectric internal sinus lift / sticky bone graft material

Intervention Type PROCEDURE

In the PISE technique, an ultrasonic piezoelectric device (acteon), to which a specialized tip is attached, is used to break the sinus floor. Developed for sinus lift by the crestal approach, the Intralift™ Kit makes it possible to undertake dental non invasive surgery in full safety.

The diamond-coated tips, of increasing diameters (from 1.35mm to 2.80mm), are designed to drill and gradually widen the access canal to the sinus membrane. The sterile spray cools the tips down to avoid any rise in temperature, which could lead to oral tissue damage.The membrane elevation is achieved using the TKW5 by means of microcavitation. Thanks to the ultrasonic frequency modulation, the risk of membrane damage is limited. Moreover, the cavitation effect enables excellent visibility of the operating field.
