Piezoelectric Osteotomy and Ridge Expansion Technique In Edentulous Mandibular For Dental Implants

Abstract : The mandibular ridge is characterized by high resorption rate following teeth extraction in the early period, followed by a remarkably slowing rate within the first year, ending by a slower gradual continuous and irreversible decrease in resorption'l+". This may result in narrow ridges with associated problem of insufficient bone to accept future prosthesis (4). Several classifications were reported in the literature (5·10) as regards ridge resorption in order to describe the anatomical variations in different anatomic levels and estimation of the bone height and width and amount of basal bone to be used by the clinician for establishing a relational plan of treatment. Problems associated with management of edentulous resorbed ridges with insufficient bone thickness presents a challenge for prosthetic replacement. Various surgical approaches were reported including: soft -tissue vestibuloplasty; ridge augmentation with alloplastic or biologic materials; and implantation (II) Placement of dental implants in narrow ridges using ridge split osteotomy may result in fracture during osteotomy (12). Ridge expansion techniques were described by Dr. Summers using osteotomes (13), this was followed by other expansive techniques (split crest, edentulous ridge expansion [ERE], ridge expansion osteotomy [REO]) which were used in Class IV premaxilla and posterior mandibular levels they uniformly claimed that the osteotome technique whenever compared with traditional drilling techniques using burs carries several advantages specially in atrophic bone(13.17). Trials on the development of ultrasonic devices throughout the literature started as early as 1934 by Hayes (18). The true turning point occurred when in 1997 Vercelloti (19), used some ultrasonic instruments for ablation to remove an ankylotic root and immediately realized the limits in cutting bone not more than Imrn thick with marginal necrosis due to overheating. Subsequently, Vercelloti(19) realized that the limited power enabled osteotomy only with thin sharp inserts, hence he underwent a scientific technological research project with a team which purpose was to develop an ideal ultrasonic technology for bone cutting and ended up with the development of an initial prototype called "Piezosurgery". Unfortunately, the higher power over ablators only slightly improved cutting performance and caused excessive overheating of the bone. Pursuing researches with a team of scientists extensive research ended up by the invention of new surgical techniques with new disciplines in 1999 "Piezoelectric Bone Surgery" the greek word piezo means pressure, it is the result of
