Efficacy of Modified Piezosurgery Alveolar Bone Cut With Osseodensification Drills in Expanding Narrow Alveolar Bone

the surgical procedure started with envelop 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. Measuring the width of the alveolar ridge 1 mm below the crest using bone caliber. Using piezoelectric surgery unit (Piezosurgery Ultrasonic® mectron, Italy), a horizontal crestal cut was produced along the crest of the bone. The cut depth extended into the same depth of the final dental implant to be inserted and then Versah Drills will be used in a successive manner and under copious irrigation with chilled sterile normal saline.We will measure the rate of ridge expansion by bone caliber to determine the efficacy of combining Versah drills with piezo surgery in expanding narrow alveolar bone.
