Atraumatic ridge expansion and implant site preparation with motorized bone expanders.

The osteotome technique has been utilized for many years as a viable approach to expand atrophic ridges. Despite its effectiveness, the mechanical impact from the surgical mallet is not well tolerated by patients. Additionally, reports in the literature describe postoperative complications that include concussions and benign paroxysmal vertigo. These conditions can be alarming for the patient and clinician, as their effects may persist for several weeks. A new technique for atraumatic ridge expansion has been developed that introduces the surgical use of motor-driven instruments at low speeds.
