The Effect of Piezosurgical Ridge Splitting and Osseodensification on The Primary Stability of The Implant in Narrow Ridge: (Comparative Randomized Controlled Split Mouth Clinical Trial)

Aim: This study aims to evaluate the effect of and compare between the piezosurgical ridge splitting and osseodensification in implant primary stability.  Subjects and Methods: 28 implants were divided into two groups. Group I: 14 implants in sites received piezosurgery technique. Group II: 14 implants in sites received osseodensification technique.  Then, all implants were evaluated clinically  for primary stability after implant insertion by Osstell mentor magnetic resonance device and radiographically for peri-implant bone density.  Results: unpaired t-test between the two groups showed moderate statistical significant difference in group  II when compared with group I in both primary stability and bone density  Conclusion:  The primary stability in both piezosurgical ridge splitting and osseodensification techniques is within normal range but in favor of osseodensification technique suggesting that osseodensification enhance the bone density thereby improve the implant primary stability.
