Evaluation of Implant Stability after Conventional Versus Piezoelectric Alveolar Ridge Splitting with Immediate Implantation in Mandibular Posterior Region “A Randomized Controlled Trial”

Abstract

Aim of the Study: The purpose of this study is to answer a clinical question whether the use of piezoelectric alveolar ridge splitting (ARS) with simultaneous implant placement will enhance implant stability in comparison with conventional motorized surgical disc and bur or not.Materials and Methods: twenty four dental implants were placed in fourteen edentulous ridges and were divided into 2 equal groups (Group I & Group II). Patients in both groups underwent ARS for narrow edentulous posterior mandibular ridge with simultaneous implant placement. In Group I, 12 implants were placed in 8 edentulous ridges after ARS performed using piezoelectric saws. In Group II, 12 implants were placed in 6 edentulous ridges after ARS performed using conventional motor driven surgical disc and bur. Implant stability was measured by means of Osstell TM device, first intraoperatively, then at 6 months and 9 months postoperatively. Moreover, radiographic assessment of marginal bone loss (MBL) was done at 6 months postoperatively. Bone width gain was calculated from pre and post-operative cone beam CT.Results: Regarding implant stability, there was a statistically significant difference between the two groups at all time intervals. Regarding MBL, and width gain, there was no statistically significant difference between both groups.Conclusion: Piezosurgery enhanced implant stability but didn’t mitigate the bone loss associated with ARS or increase amount of ridge width gain.
