Evaluation of Dental Implant Stability in Narrow Alveolar Ridges Utilizing Osseodensification Technique Versus Screw Expansion: A Comparative Clinical Study

This study aimed to evaluate implant primary stability using Densah bur in comparison with screw expander in narrow alveolar ridge.

The patient is instructed to gargle with 0.2% chlorhexidine mouthwash, scrubbing the perioral area with 10% povidone iodine and draping the patient head with disposable drapes.

The surgery will be performed under local anesthesia using lidocaine hydrochloride 2% with adrenaline 1:8000, the surgical procedure started with flap reflection. A mucoperiosteal elevator was used to reflect the buccal and palatal flaps that were enough to expose the crestal part of alveolar ridge with clear visibility and accessibility.

For Expander group:

The screw expanders will be use to expand the osteotomy site. The diameters will be use 2.3mm ,2.6 mm, 3 mm, 3.4 mm, 3.8 mm in a successive manner. Each expander will be screw until 10 mm of depth is reached as mark on the expander. Each expanders is gently screwed half turn at a time; to allow slow and gradual expansion of the bone . When necessary, the kit ratchet is used to reach the full depth required. After the use of the final expander, an implant of appropriate size will place.
