The Effect of Simvastatin With Guided Bone Regeneration in Ridge Splitting and Simultaneously Implantation

Study Overview
=================
Brief Summary
-----------------
Ridge split augmentation technique, with immediate implant placement, reduces the time of the treatment and the time of the final prosthetic reconstruction. Furthermore, compression of the bone increases its density. SMV is also found to promote osteogenic differentiation of bone marrow stem cells, suppress osteoclastic differentiation in bone tissue, and promotes osseointegration around implants in animal studies. The aim of this study is to compare surgical outcomes of the application of the alveolar ridge splitting (ARS) in combination with guided bone regeneration (GBR) using bone grafting and a barrier membrane, associated with immediate implant placement versus ARS in combination with the use of SMV with GBR using bone grafting and a barrier membrane, associated with immediate implant placement in patients with horizontally atrophic jaw bones.
